There may be energy procurement opportunities for the Township of Raritan to reduce annual electricity costs, which are $7,471 higher, when compared to the average estimated NJ commercial electricity rates. SWA recommends further negotiation with energy suppliers, listed in Appendix D. Environmental Benefits SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 16 cars from the roads each year or is equivalent of planting 481 trees to absorb CO 2 from the atmosphere. Energy Conservation Measure Implementation Based on the requirements of the Local Government Energy Audit (LGEA) program, the Township of Raritan must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report’s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit per building. The minimum amount to be spent, net of other NJCEP incentives, is $1,987. SWA recommends that the Township of Raritan implement the following Energy Conservation Measures using an appropriate Incentive Programs for reduced capital cost: Recommended ECMs Install 37 Occupancy sensors Retrofit the vending machines with VendingMisers Add a new condensing boiler Retro-commission the HVAC systems Install a 20kW PV system

INTRODUCTION Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, ‘whole building’ strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the municipal building at 1 Municipal Drive, Flemington. The process of the audit included facility visits on February 4th, 2011, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and other recommendations for improvements. The scope of work includes providing a summary of current building conditions, current operating costs, potential savings, and investment costs to achieve these savings. The facility description includes energy usage, occupancy profiles and current building systems along with a detailed inventory of building energy systems, recommendations for improvement and recommendations for energy purchasing and procurement strategies. The goal of this Local Government Energy Audit is to provide sufficient information to the Township of Raritan to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures for the Municipal building.

HISTORICAL ENERGY CONSUMPTION Energy usage, load profile and cost analysis SWA reviewed utility bills from January 2009 through December 2010 that were received from the utility companies supplying the municipal building with electric and natural gas. A 12 month period of analysis from December 2009 through November 2010 was used for all calculations and for purposes of benchmarking the building. Electricity - The municipal building is currently served by one electric meter. The municipal building currently buys electricity from JCP&L at an average aggregated rate of $0.166/kWh and consumed approximately 453,480 kWh, or $75,493 worth of electricity, in the previous year. The average monthly demand was 111.3 kW and the annual peak demand was 130.6 kW. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate baseload or minimum electric usage required to operate the municipal building.
Natural gas - The municipal building is currently served by one meter for natural gas. The municipal building currently buys natural gas from Elizabethtown Gas Co. at an average aggregated rate of $1.075/therm and consumed approximately 23,977 therms, or $25,764 worth of natural gas, in the previous year. The chart below shows the monthly natural gas usage and costs. The green line represents the approximate baseload or minimum natural gas usage required to operate the municipal building.

The chart above shows the monthly natural gas usage along with the heating degree days or HDD. Heating degree days is the difference of the average daily temperature and a base temperature, on a particular day. The heating degree days are zero for the days when the average temperature exceeds the base temperature. SWA’s analysis used a base temperature

of 65 degrees Fahrenheit. This chart shows that the gas used curve does not follow the HDD curve during the summer months and that there is considerable gas used for building heating even during the summer. The following graphs, pie charts, and table show energy use for the Municipal building based on utility bills for the 12 month period.

Energy benchmarking SWA has entered energy information about the municipal building in the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system. This municipal building is categorized as an office facility space type and is eligible to receive a national energy performance rating. The present benchmarking score of the building is 28. The Site Energy Use Intensity is 115 kBtu/sqft/yr compared to the national average of an office
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 8/58
building consuming 91 kBtu/sqft/yr. See ECM section for guidance on how to improve the building’s rating. Additionally, should the municipality desire to better this average, there are other large scale and financially less advantageous improvements that can be made, such as large scale HVAC upgrades.
Per the LGEA program requirements, SWA has assisted the Township of Raritan to create an ENERGY STAR® Portfolio Manager account and share the municipal building facilities information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Township of Raritan (user name of “RaritanTownship” with a password of “RaritanTownship”) and TRC Energy Services (user name of “TRC-LGEA”). Tariff analysis Tariff analysis can help determine if the municipality is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Natural gas prices often increase during winter months since large volumes of natural gas is needed for heating. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the Township of Raritan. The Municipal building is currently paying a general service rate for natural gas including fixed costs such as meter reading charges. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on

electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Energy Procurement strategies Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electricity are $0.150/kWh, while the municipal building pays a rate of $0.166/kWh. The municipal building annual electric utility costs are $7,471 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 7% over the most recent 12 month period.
Electric rate fluctuations follow the expected pattern with a peak during the summer, drop-offs in the shoulder months and a small rise in the winter due to the high energy rates. The average estimated NJ commercial utility rates for gas are $1.550/therm, while municipal building pays a rate of $1.075/therm. Natural gas bill analysis shows fluctuations up to 38% over the most recent 12 month period.
Steven Winter Associates, Inc. - LGEA Report

Page 10/58
Natural Gas rate fluctuations may have been caused by fixed fees and costs assessed during the summer months when usage is at a minimum. SWA recommends that the municipal building further explore opportunities of purchasing both natural gas and electricity from third-party suppliers in order to reduce rate fluctuation and ultimately reduce the annual cost of energy for the municipal building. Appendix C contains a complete list of third-party energy suppliers for the Township of Raritan service area.

Building Envelope Due to favorable weather conditions (min. 18 deg. F delta-T in/outside and no/low wind), some exterior envelope infrared (IR) images were taken during the field audit. IR technology helps to identify energy-compromising problem areas in a non-invasive way. Exterior Walls The exterior wall envelope is mostly constructed of 6” 16 Gauge metal stud wall with a 5/8” concrete board to its exterior and either a 2” stone veneer or precast concrete finish with 4 inches of fiberglass batt cavity insulation. There are also some sections constructed of 2” EIFS with either concrete masonry units or metal stud walls to its interior with R-19 fiberglass batt insulation. Note: Wall insulation levels could not be verified in the field and are based on available construction plans. Exterior and interior wall surfaces were inspected during the field audit. They were found to be in overall good condition with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. The following specific exterior wall problem spots and areas were identified:
Typical wall surfaces with some signs of uncontrolled roof water runoff on walls due to defective roof flashing and damaged and clogged gutters and downspouts.

Base The building’s base is composed of a slab-on-grade floor with a perimeter footing with poured concrete foundation walls and a slab edge/perimeter insulation. Slab/perimeter insulation levels could not be verified in the field and are based on available construction plans. The building’s base and its perimeter were inspected for signs of uncontrolled moisture or water presence and other energy-compromising issues. Overall the base was reported to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energycompromising issues neither visible on the interior nor exterior. Windows The building contains basically two different types of windows. 1. Fixed type windows of different sizes with an insulated aluminum frame, clear double glazing and interior mini blinds. The windows are located throughout the building and are original. 2. Sidelight and transom windows alongside glass doors with an insulated aluminum frame, clear double glazing and no shading. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues.

The following IR images further illustrate the good condition of the existing doors:
Building air-tightness Overall the field auditors found the building to be reasonably air-tight, considering the building's use and occupancy, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses. Mechanical Systems Heating Ventilation Air Conditioning The Municipal Building is fully heated and cooled. There were no major comfort related complaints from the building occupants. A minor complaint noted was regarding lack of temperature control arising due to lack of air movement in one of the toilets. Equipment The Municipal Building contains four indoor heating/cooling packaged units, hot water boilers, a chiller, pumps, and ventilation fans. A comprehensive Equipment List can be found in Appendix A. The building contains four Trane air handling units (AHUs) equipped with chilled and hot water coils for cooling and heating the building. The units are equipped with supply and return air fans, both controlled by variable frequency drives (VFD). The fan motors were all NEMA premium efficiency motors and the VFDs were seen to be operating fine. For example, VFD for unit AC-1 supply was seen at 36.1Hz, for unit AC-2 supply at 41.7 Hz, and for unit AC-3 at 43.8Hz. All the units were installed in 2002 and have about 60% of service life remaining and appeared to be in good condition. The heating hot water is produced by five (5) gas-fired, Slant/Fin, Galaxy hot water boilers located in the Mechanical room. The boilers are rated for 399MBH input each and have an estimated 81% thermal efficiency. The boilers were installed in 2002 and have about 68% of remaining usable service life of a small commercial boiler of 20 years according to the LGEA

equipment lifespan guidelines. The boilers appear to be in good condition ion as seen in the picture below.
Slant/Fin boilers – appear to be in good condition Chilled water is provided to various air handling units from one 125 ton air cooled Trane chiller located outside on grade. The chiller was installed in 2002 and is in good condition. It is rated for 10.5 EER at full load, and 9.8 EER at full load. The chiller still has about 68% of useful life remaining.
Trane Air cooled chiller There are five exhaust fans which exhaust air from the bathrooms and the kitchen areas of the building. The fans appeared to be in good condition and had about 47% of their service life remaining.

Distribution Systems The air is delivered to various spaces within the building using distribution ducts. There are terminal variable air volume (VAV) boxes. The building is divided into four main zones, and each zone is served by a central Trane air handling unit. The return air is either fed back into the unit or exhausted out of the building. Hot water is distributed to the air handling units and to the VAV boxes by a hot water pipe distribution system. There are two hot water pumps and only one pump works at a time; other remains on the standby. Each pump is equipped with a 7.5hp NEMA premium efficiency motor. Chilled water is distributed to the air handling units by a chilled water pipe distribution system. There are two chilled water pumps and only one pump works at a time; other remains on the standby. Each pump is equipped with a 7.5hp NEMA premium efficiency motor.
Hot water pumps
Chilled water pumps
Controls There is no central building management system for equipment controls. The main equipment like chillers, boilers, air handling units, etc. are controlled from local, stand alone, dedicated controls systems. These local controls systems don’t seem to communicate with each other effectively. The boilers are controlled by a wall mounted controls system manufactured and installed by Tekmar controls. It regulates supply water temperature based on outside air temperature or through indoor air temperature through a 10K zone control. The system pump is turned on when there is a heat demand and the outdoor temperature is cool enough to require heat into the system in the winter. There is an internal timer to program schedules for occupied and unoccupied modes settings. Each air handling unit has a standalone controls system with a time clock, which is individually set for occupied and unoccupied modes. The morning warm up schedule is initiated in going from unoccupied to occupied mode. Supply and return fans are equipped with variable frequency drives, which control the fan speed based on the duct mounted pressure sensor signal. The duct distribution system comprises variable air volume boxes
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 19/58
serving various spaces. The discharge air controller uses the enthalpy based economizers to vary the ventilation air in the shoulder seasons. During unoccupied modes, the supply fan and return fans are shut down and there is no ventilation; supply fans turn on only if the night set back temperature signal demand for more heat. The VAV box is connected to its own thermostat and maintains air flow in the space to control the temperature and ventilation.
Boilers control
Variable Frequency Drive
VAV thermostat
Chiller is programmed to run if the outside air temperature rises above 60 deg F. The chiller and the chilled water pumps are interlocked. Based on the utility bill analysis there is natural gas heating used in the VAV hot water coils from May to November, and this would be considered a wasteful use of energy inherent with these types of HVAC systems employing VAVs. There is no simple solution to deal with this situation – some building users simply shut down the boilers in the summer time and rely on the occupants to war warm clothing if the room feels cold. Domestic Hot Water The domestic hot water (DHW) for the Municipal Building is provided by two AO Smith natural gas heaters. One DHW is of 30 gallons storage and rated for 32 MBH input, and the other is of 50 gallons storage and rated for 42MBH input. Both are estimated to have an efficiency of 80% and were installed in 2002. They have about 38% of remaining service life.

Electrical systems Lighting See attached lighting schedule in Appendix B for a complete inventory of lighting throughout the building including estimated power consumption and proposed lighting recommendations. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July 2012. Interior Lighting - The municipal building currently contains mostly T8 lamped electronically ballasted fixtures and self-ballasted compact fluorescent lamps. There are also a few incandescent self-ballasted lamps in the courtroom and offices. Based on measurements of lighting levels for each space, there are no vastly over-illuminated areas. Exit Lights - Exit signs were found to be of the LED type. Exterior Lighting - The exterior lighting surveyed during the building audit was found to be a mix of metal halide lamp and incandescent fixtures. Exterior lighting is controlled by automatic timers.
Appliances and process SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as “plug-load” equipment, since they are not inherent to the building’s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building’s energy usage based on utility analysis. There are two older model refrigerated vending machines that SWA recommends to be retrofitted VendingMiser® devices. Also installed at the municipal building is a newer model Frigidaire manufactured refrigerator that should remain and two older model Summit manufactured refrigerators that should be replaced with new Energy Star certified units.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES Renewable energy is defined as any power source generated from sources which are naturally replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving and the cost of installation is decreasing due to both demand and the availability of governmentsponsored funding. Renewable energy reduces the need for using either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased from the utility company. Solar photovoltaic panels and wind turbines use natural resources to generate electricity. Geothermal systems offset the thermal loads in a building by using water stored in the ground as either a heat sink or heat source. Cogeneration or Combined Heat and Power (CHP) allows for heat recovery during electricity generation. Existing systems Currently there are no renewable energy systems installed in the building. Evaluated Systems Solar Photovoltaic Photovoltaic panels convert light energy received from the sun into a usable form of electricity. Panels can be connected into arrays and mounted directly onto building roofs, as well as installed onto built canopies over areas such as parking lots, building roofs or other open areas. Electricity generated from photovoltaic panels is generally sold back to the utility company through a net meter. Net-metering allows the utility to record the amount of electricity generated in order to pay credits to the consumer that can offset usage and demand costs on the electric bill. In addition to generation credits, there are incentives available called Solar Renewable Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the municipal building is a good candidate for a 20 kW Solar Panel installation. See ECM#9 for details. Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure. Wind The municipal building is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The municipal building is not a good candidate for geothermal installation since it would require replacement of the entire existing HVAC system, of which major components still have between 30% and 70% remaining useful life.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 23/58
Combined Heat and Power The municipal building is not a good candidate for CHP installation and would not be costeffective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently.

ECM#3: Install thirty-seven (37) new occupancy sensors On the days of the site visits, SWA completed a lighting inventory of the Township of Raritan Municipal Building (see Appendix B). The building contains twenty areas that could benefit from the installation of occupancy sensors. These areas consisted of various meeting rooms and offices that are used sporadically throughout the day and could show energy savings by having the lights turn off after a period of no occupancy. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advanced micro-phonic lighting sensors include sound detection as a means to controlling lighting operation.

ECM#4: Replace two (2) refrigerators with 18 cu. ft. ENERGY STAR® models On the day of the site visit, SWA observed that there were two older refrigerators, 18 cu. ft. models in the building which were not Energy Star rated (using approximately 380 kWh/year). Appliances, such as refrigerators, that are over 10 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerators with a 18 cu. ft. ENERGY STAR® refrigerator. Besides saving energy, the replacement will also keep their surroundings cooler. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

ECM #5: Add a new lead Condensing Gas Boiler The heating hot water is produced by five (5) gas-fired, Slant/Fin, Galaxy hot water boilers located in the Mechanical room. The boilers are rated for 399MBH input each and have an estimated 81% thermal efficiency. The boilers were installed in 2002 and appear to be in good condition. The utility bill analysis shows that the boilers are used throughout the year because of the demand for hot water in VAV reheat coils during summer. In this light, SWA recommends adding a 300 MBH boiler of higher efficiency. The new boiler will become the lead boiler and work to meet 85% or more of the regular heating load. The back up boilers would fire only in extreme weather and for any emergencies. Condensing boilers allow condensation of moisture in flue gases resulting in lower flue gas temperatures with increased efficiencies up to 95%. The new high efficiency condensing boilers should have a guaranteed minimum thermal efficiency of 85% and efficiencies of up to 95% achievable during condensing mode at lower return water temperatures.

There may be energy procurement opportunities for the Township of Raritan to reduce annual utility costs, which are $2,313 higher, when compared to the average estimated NJ commercial utility rates. SWA recommends further negotiation with energy suppliers listed in Appendix C. Environmental Benefits SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 3 cars from the roads each year or is equivalent of planting 88 trees to absorb CO 2 from the atmosphere. Energy Conservation Measure Implementation Based on the requirements of the Local Government Energy Audit (LGEA) program, the Township of Raritan must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report’s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit per building. The minimum amount to be spent, net of other NJCEP incentives, is 1,468. SWA recommends that the Township of Raritan implement the following Energy Conservation Measures using an appropriate Incentive Programs for reduced capital cost: Recommended ECMs Replace T12 light fixtures with T8 Replace existing domestic water heater Install occupancy sensors Install programmable thermostat with controller Install a 20kW PV system

INTRODUCTION Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, ‘whole building’ strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the Public Works Department Building at 1 Municipal Drive, Flemington. The process of the audit included facility visits on February 4th, 2011, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and other recommendations for improvements. The scope of work includes providing a summary of current building conditions, current operating costs, potential savings, and investment costs to achieve these savings. The facility description includes energy usage, occupancy profiles and current building systems along with a detailed inventory of building energy systems, recommendations for improvement and recommendations for energy purchasing and procurement strategies. The goal of this Local Government Energy Audit is to provide sufficient information to the Township of Raritan to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures for the Public Works Department Building.

HISTORICAL ENERGY CONSUMPTION Energy usage, load profile and cost analysis SWA reviewed utility bills from January 2009 through December 2010 that were received from the utility companies supplying the Public Works Department Building with electric and propane. A 12 month period of analysis from December 2009 through November 2010 was used for all calculations and for purposes of benchmarking the building. Electricity - The Public Works Department Building is currently served by one electric meter. The Public Works Department Building currently buys electricity from JCP&L at an average aggregated rate of $0.153/kWh and consumed approximately 154,707 kWh, or $23,641 worth of electricity, in the previous year. The average monthly demand was 44.1 kW and the annual peak demand was 47.5 kW. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate baseload or minimum electric usage required to operate the Public Works Department Building.
Propane - The Public Works Department Building is currently served by one meter for propane. The Public Works Department Building currently buys propane from the Suburban Propane Company at an average aggregated rate of $2.304/gallon and consumed approximately 6,174 gallons, or $14,225 worth of propane, in the previous year. The chart below shows the monthly propane usage and costs. The green line represents the approximate baseload or minimum propane usage required to operate the Public Works Department Building.

The following graphs, pie charts, and table show energy use for the Public Works Department building based on utility bills for the 12 month period. Note that the electricity cost at $45/MMBtu of energy is almost 3 times as expensive as propane at $17/MMBtu.
Energy benchmarking SWA entered the energy information about the Public Works Department Building in the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system. This Public Works Department Building is categorized as an “other service” facility space type and was not eligible to receive a national energy performance rating. The Site Energy Use Intensity is 57 kBtu/sqft/yr compared to the national average of an “other – service” building consuming 104 kBtu/sqft/yr. See ECM section for guidance on how to improve the building’s rating. Additionally, should the municipality desire to reach this average there are other large scale and financially less advantageous improvements that can be made, such as envelope window, door and insulation upgrades that would help the building reach this goal.

Per the LGEA program requirements, SWA has assisted the Township of Raritan to create an ENERGY STAR® Portfolio Manager account and share the Public Works Department Building facilities information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Township of Raritan (user name of “RaritanTownship” with a password of “RaritanTownship”) and TRC Energy Services (user name of “TRC-LGEA”). Tariff analysis Tariff analysis can help determine if the municipality is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Propane prices often increase during winter months since large volumes of propane are needed for heating equipment. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling equipment. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the Township of Raritan. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Energy Procurement strategies Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 9/50
inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electric are $0.150/kWh, while the Public Works Department Building pays a rate of $0.153/kWh. The Public Works Department Building annual electric utility costs are $435 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 12% over the most recent 12 month period. Electric rate fluctuations follow the expected pattern with a peak during the summer, drop-offs in the shoulder months and a small rise in the winter due to the high energy rates.
The average estimated NJ commercial utility rates for propane are $2.00/gallon, while Public Works Department Building pays a rate of $2.304/gallon. The Public Works Department Building annual propane costs are $1,878 higher, when compared to the average estimated NJ commercial utility rates. Propane bill analysis shows fluctuations up to 37% over the most recent 12 month period. Propane rate fluctuations may have been caused by fixed fees and costs assessed during the summer months when usage is at a minimum. SWA compared the cost of Propane to the cost of Natural gas as follows: on a per therm basis, the cost of propane works out to $1.70/therm, whereas the average New Jersey gas rates are about $1.5/therm. The Public Works Department pays about 15% more than it would have paid had it been served with natural gas, based on the average prevailing New Jersey rates.

EXISTING FACILITY AND SYSTEMS DESCRIPTION This section gives an overview of the current state of the facility and systems. Please refer to the Proposed Further Recommendations section for recommendations for improvement. Based on visits from SWA on Friday, February 04, 2011, the following data was collected and analyzed. Building Characteristics The single story, slab on grade, 24,000 square feet public works facility was originally constructed in 1986. It houses administration offices, locker rooms, garage spaces and various work stations.
Partial Southwest Façade
Partial Southeast Façade
Partial Northeast Façade
Partial Northwest Façade
Building Occupancy Profiles Its occupancy is approximately 27 employees daily from 7:30 to 3:30 Monday through Friday and as necessary based on emergency conditions. Building Envelope Due to favorable weather conditions (min. 18 deg. F delta-T in/outside and no/low wind), some exterior envelope infrared (IR) images were taken during the field audit. IR technology helps to identify energy-compromising problem areas in a non-invasive way.

Exterior Walls The exterior wall envelope is mostly constructed of exposed and painted CMU (Concrete Masonry Unit) and some CMU (Concrete Masonry Unit) with fluted brick finish. No insulation was recorded. The interior is mostly exposed CMU (Concrete Masonry Unit) and painted gypsum wallboard. Note: Wall insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction. Exterior and interior wall surfaces were inspected during the field audit. They were found to be in overall good condition with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. The following specific exterior wall problem spots and areas were identified:
Cracked caulk, shifted brick, signs of water damage and uncontrolled roof water runoff due to damaged gutters.
The following IR images further demonstrate the condition of the exterior walls:

Roof The building has a three tier roof with one above the offices and two above the garage. All three are predominantly a flat or slightly sloped, no parapet type over steel decking, with a light-colored EPDM single-membrane finish. It is original with three and a half inches of roof insulation. Note: Roof insulation levels could not be verified in the field, and are based on available construction plans. Roofs, related flashing, gutters and downspouts were inspected during the field audit. They were reported to be in overall good condition, with no signs of uncontrolled moisture, airleakage or other energy-compromising issues detected on all roof areas. The following typical roof systems were identified:
Typical roof systems. Base The building’s base is composed of a slab-on-grade floor with a perimeter foundation and no detectable slab edge/perimeter insulation. Slab/perimeter insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction.

The building’s base and its perimeter were inspected for signs of uncontrolled moisture or water presence and other energy-compromising issues. Overall the base was reported to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energycompromising issues neither visible on the interior nor exterior. Windows The building contains basically three different types of windows. 1. Unit (fixed and hopper) type windows with a non-insulated aluminum frame, clear single glazing and no interior or exterior shading devices. The windows are located throughout the building and are original. 2. Slider type windows with a non-insulated aluminum frame, clear double glazing and no interior or exterior shading devices. The windows are located in the sign room mezzanine only. 3. Typical transom and sidelight windows alongside the glass doors. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. The following specific window problem spots were identified:
Typical exterior windows. Exterior doors The building contains several different types of exterior doors. 1. Solid metal type exterior doors. They are located throughout the building and are original. 2. Overhead aluminum type exterior doors with glass panels. They are located throughout the garage areas and are original. 3. Glass with aluminum/steel frame type exterior doors. They are located on the north façade at the main entrance. All exterior doors, thresholds, related flashing, caulking and weather-stripping were inspected for signs of moisture, air-leakage and other energy-compromising issues. Overall, the doors were found to be in good condition with no signs of uncontrolled moisture, airleakage and/ or other energy-compromising issues.

The following specific door problem spots were identified:
Typical exterior doors. Building air-tightness Overall the field auditors found the building to be reasonably air-tight, considering the building's use and occupancy, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses. Mechanical Systems Heating Ventilation Air Conditioning The DPW Building is fully heated and only partly cooled. There were no major comfort related complaints from the building occupants. Equipment The DPW Building contains two roof mounted packaged units, nine propane fired unit heaters, an infra-red heating tube, and ventilation fans. A comprehensive Equipment List can be found in Appendix A.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 16/50
The rooftop units contain a propane fired burner for heating and a direct expansion (DX) system for cooling, made up of an evaporator, condenser and refrigerant loop. The units were manufactured by York and installed around 2005. The units have about 60% remaining life and appear to be in good condition. The packaged units are rated for 9 EER in efficiency. Considering that the current units still have a good amount of useful service life remaining, SWA does not recommend replacing these units with higher efficiency units in the near future due to economic considerations. The units consist of a down flow enthalpy controlled economizer which varies the outside air quantity based on the outside air temperature.
Roof top packaged units – appear to be in good condition The DPW building contains areas that are heated only by propane fired ceiling hung unit heaters. There is a small unit heater for the “Sign Shop”; there is one small unit heater serving the “Wash Bay”; and there are seven relatively larger unit heaters installed in the “Storage Garage”. The Wash Bay heater was found to be in non-working condition, and so were four of the heaters in the Storage Garage. The Shop area was also equipped with an overhead infra red heating tube manufactured y CoRayVac. The office type spaces of the building are provided ventilation by outside air intake louvers on the rooftop units. The outside air louvers are motorized to allow economizer operation when the outside air conditions are favorable. The shop floor is provided ventilation by means of various exhaust fans. SWA noted that most of the ventilation fans were operating beyond the service life of a ventilation fan of 10 years. Distribution Systems The air is delivered to various spaces within the building using distribution ducts. There are supply and return air ducts terminating at the roof top packaged units. The exhaust air is either returned back or exhausted using the unit power exhauster. The supply air is a mixture of returned air and fresh air. Supply air is either heated or cooled depending on the space thermostat setting and requirement. Controls Roof top packaged units are controlled from individual programmable thermostats. The thermostats seemed to be programmed for night set backs during the winter months. There is no central building management system for equipment controls. The unit heaters are mostly controlled by manual thermostats of two types as show below. Various exhaust fans are switch operated and turned on manually if required.

Programmable Thermostats for RTU; Non programmable ones for unit heaters Domestic Hot Water The domestic hot water (DHW) for the DPW Building is provided by one large heater. There is one propane fired heater with 250 gallons storage and rated for 243 MBH input and an estimated 70% efficiency. The heater was installed in 1985 and is operating well beyond its estimated service life of 13 years, and looks like it is badly in need of replacement.
Domestic Hot Water Heater Electrical systems Lighting See attached lighting schedule in Appendix B for a complete inventory of lighting throughout the building including estimated power consumption and proposed lighting recommendations. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July 2012.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 18/50
Interior Lighting - The Public Works Department Building currently contains mostly T12 lamped magnetically ballasted fixtures and self-ballasted compact fluorescent lamps. There are also high bay metal halide and high pressure sodium lamped fixtures. Based on measurements of lighting levels for each space, there are no vastly over-illuminated areas. Exit Lights - Exit signs were found to be a mixture of the LED and incandescent type. Exterior Lighting - The exterior lighting surveyed during the building audit was found to be high pressure sodium lamped fixtures. Exterior lighting is controlled by automatic timers.
Appliances and process SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as “plug-load” equipment, since they are not inherent to the building’s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building’s energy usage based on utility analysis. There is one older model refrigerated vending machine that SWA recommends to be retrofitted with VendingMiser® devices. Also installed at the Public Works Department Building are two older model refrigerators that should be replaced with new Energy Star certified units. One of those units is a large 17 cubic foot unit and the other is a compact unit. Elevators The Public Works Department Building does not have an installed elevator. Other electrical systems There is no significant energy-impacting electrical systems installed at the Public Works Department Building.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES Renewable energy is defined as any power source generated from sources which are naturally replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving and the cost of installation is decreasing due to both demand and the availability of governmentsponsored funding. Renewable energy reduces the need for using either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased from the utility company. Solar photovoltaic panels and wind turbines use natural resources to generate electricity. Geothermal systems offset the thermal loads in a building by using water stored in the ground as either a heat sink or heat source. Cogeneration or Combined Heat and Power (CHP) allows for heat recovery during electricity generation. Existing systems Currently there are no renewable energy systems installed in the building. Evaluated Systems Solar Photovoltaic Photovoltaic panels convert light energy received from the sun into a usable form of electricity. Panels can be connected into arrays and mounted directly onto building roofs, as well as installed onto built canopies over areas such as parking lots, building roofs or other open areas. Electricity generated from photovoltaic panels is generally sold back to the utility company through a net meter. Net-metering allows the utility to record the amount of electricity generated in order to pay credits to the consumer that can offset usage and demand costs on the electric bill. In addition to generation credits, there are incentives available called Solar Renewable Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the Public Works Department Building is a good candidate for a 20 kW Solar Panel installation. See ECM#6 for details. Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure. Wind The Public Works Department Building is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The Public Works Department Building is not a good candidate for geothermal installation since only part of the building is cooled year round, making the geothermal system uneconomical to install.

Combined Heat and Power The Public Works Department Building is not a good candidate for CHP installation and would not be cost-effective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently.

ECM# 3: Install two (2) new occupancy sensors On the days of the site visits, SWA completed a lighting inventory of the Township of Raritan Public Works Department Building (see Appendix B). The building contains two areas that could benefit from the installation of occupancy sensors. These areas are the lunch room and an office that are used sporadically throughout the day and could show energy savings by having the lights turned off after a period of no occupancy. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advanced micro-phonic lighting sensors include sound detection as a means to controlling lighting operation.

ECM#4: Replace one (1) large refrigerator with 18 cu. ft. ENERGY STAR® model On the day of the site visit, SWA observed that there was one older refrigerator, 17 cu. ft. model in the building which were not Energy Star rated (using approximately 773 kWh/year). Appliances, such as refrigerators, that are over 10 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerators with a 17 cu. ft. top freezer ENERGY STAR® refrigerator. Besides saving energy, the replacement will also keep their surroundings cooler. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

ECM#5: Install (1) New Thermostats along with Controller There are two propane fired DX roof top package units serving the building, which are controlled from individual programmable thermostats. One of the units serves the Administration offices and the other unit serves the Mezzanine office/shop. Both the thermostats are programmed for occupied and unoccupied modes, separately for summer and winter operations. SWA noted that the Mezzanine area has a variable occupancy pattern, and there may be extended period of times with no occupancy at all. SWA proposes occupancy sensor based temperature settings to cut down energy usage. SWA proposes that the building install (1) new programmable thermostat, a new central controller that can be programmed infinitely from a computer, an outside air stat, and new control wiring. In the new proposed settings, the Mezzanine HVAC packaged units mentioned above would operate at a minimum setting and remain off during unoccupied hours in summer and shoulder seasons. The new thermostat would be wired into the controller and receive the schedule from here. The settings would revert to occupied mode settings on receiving an occupancy signal, and remain in the setting when the occupants are detected. The proposed temperature settings are as follows:
Proposed settings
Summer Occupied Unoccupied 78F Off
Winter Occupied Unoccupied 68F 62F
Shoulder Occupied Unoccupied 72F Off

ECM#6: Install 20 kW Photovoltaic System Currently, the Public Works Department Building does not use any renewable energy systems. Renewable energy systems such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset a portion of the purchased electricity for the building. Power stations generally have two separate electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a building uses from month to month. Demand is the amount of electrical power that a building uses at any given instance in a month period. During the summer periods, electric demand at a power station is high, due to the amount of air conditioners, lights, and other equipment being used within the region. Demand charges increase to offset the utility’s cost to provide enough electricity at that given time. Photovoltaic systems offset the amount of electricity used by a building and help to reduce the building’s electric demand, resulting in a higher cost savings. Installing a PV system will offset electric demand and reduce annual electric consumption, while utilizing available state incentives. PV systems are modular and readily allow for future expansions. The size of the system was determined considering the available roof surface area, without compromising service space for roof equipment and safety, as well as the facilities’ annual base load and mode of operation. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area (providing 13.1 watts per square foot). A 20 kW system needs approximately 87 panels which would take up 1,523 square feet. A PV system would reduce the building's electric load and allow more capacity for surrounding buildings as well as serve as an example of energy efficiency for the community. The building is not eligible for a residential 30% federal tax credit. The building owner may want to consider applying for a grant and / or engage a PV generator / leaser who would install the PV system and then sell the power at a reduced rate. Typically, a major utility provides the ability to buy SREC’s at $600/MWh or best market offer. However, this option is not available from the local utility. Please see below for more information.

Assumptions: SWA estimated the cost and savings of the system based on past PV projects. SWA projected physical dimensions based on a typical Polycrystalline Solar Panel (230 Watts, Model ND-U23-C1). PV systems are sized based on total wattage and physical dimensions for an array will differ with the efficiency of a given solar panel (W/sq ft). Rebates/financial incentives: • NJ Clean Energy - Solar Renewable Energy Certificate Program. Each time a solar electric system generates 1,000kWh (1MWh) of electricity, a SREC is issued which can then be sold or traded separately from the power. The buildings must also become net-metered in order to earn SRECs as well as sell power back to the electric grid. A total of $13,800/year, based on $600/SREC, has been incorporated in the above costs for a period of 15 years; however it requires proof of performance, application approval and negotiations with the utility.

ECM #9: Replace the existing domestic hot water heater The domestic hot water (DHW) for the DPW Building is provided by one propane fired heater with 250 gallons storage and it is rated for 243 MBH input at an estimated 70% efficiency. The heater was installed in 1985 and SWA recommends replacing the heater with another in kind. The utility bill analysis shows that the DHW is used throughout the year; however, the total DHW usage was estimated to be only 62MMBTu, or about 620 Therms, totaling about $1,041 annually. SWA concludes that the DHW load is not very high and that the heater is sparingly used – and in this light, it becomes clear that converting this heater to a natural gas fired condensing boiler would not be economical. Condensing boilers allow condensation of moisture in flue gases resulting in lower flue gas temperatures with increased efficiencies up to 95%.

PROPOSED FURTHER RECOMMENDATIONS Capital Improvements Capital Improvements are recommendations for the building that may not be cost-effective at the current time, but that could yield a significant long-term payback. These recommendations should typically be considered as part of a long-term capital improvement plan. Capital improvements should be considered if additional funds are made available, or if the installed costs can be shared with other improvements, such as major building renovations. SWA recommends the following capital improvements for the Public Works Department Building: •
Convert the building to natural gas - SWA analyzed that the Public Works Department building pays about 15% more than it would pay had it been served with natural gas, based on the average prevailing New Jersey rates, which works out to about $2,100 annually as the total Propane annual cost is $14,225. The building personnel expressed an interest to convert the building from Propane to Natural gas, and had obtained a quote of about $15,000 to convert all the Propane fired burners to Natural gas. This conversion would work out to about 7 year simple payback. SWA recommends the building to strongly converting away from Propane.
•
Convert Propane unit heaters to infra red heaters – Majority of the building shop already contains propane fired infra red heating tubes. The adjoining Storage garage and the Wash areas were equipped with propane fired unit heaters operated by thermostats, some of which were not even functional. SWA recommends the Township of Raritan to install infra red heating tubes in lieu of the unit heaters. These areas are not usually occupied with people and are not cooled during summer. They are maintained at a low temperature throughout the winter, in order to keep the salt moist and water above freezing. Hence, the savings from the replacement alone would not justify the investment, and this measure should be treated as a capital improvement.
•
Replace exhaust fans – There are about 6 exhaust fans which are either not in operating conditions or are operating beyond their useful service lives. SWA recommends the Township of Raritan to replace these exhaust fans with new, in kind ones. The energy savings alone would be marginal, and the replacement is expected to cost about $3,500.
•
Install premium motors when replacements are required - Select NEMA Premium motors when replacing motors that have reached the end of their useful operating lives.
•
Re-caulk all shifted brick.
Operations and Maintenance Operations and Maintenance measures consist of low/no cost measures that are within the capability of the current building staff to handle. These measures typically require little investment, and they yield a short payback period. These measures may address equipment settings or staff operations that, when addressed will reduce energy consumption or costs. •
Clean and maintain gutters, downspouts and downspout deflectors to minimize uncontrolled roof water run-off causing exterior wall damage.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 33/50
•
Maintain weather-stripping around all exterior doors and roof hatches.
•
Provide water-efficient fixtures and controls - Adding controlled on/off timers on all lavatory faucets is a cost-effective way to reduce domestic hot water demand and save water. Building staff can also easily install faucet aerators and/or low-flow fixtures to reduce water consumption. There are many retrofit options, which can be installed now or incorporated as equipment is replaced. Routine maintenance practices that identify and quickly address water leaks are a low-cost way to save water and energy. Retrofitting with more efficient water-consumption fixtures/appliances will reduce energy consumption for water heating, while also decreasing water/sewer bills.
•
SWA recommends that the building considers purchasing the most energy-efficient equipment, including ENERGY STAR® labeled appliances, when equipment is installed or replaced. More information can be found in the “Products” section of the ENERGY STAR® website at: http://www.energystar.gov.
•
Use smart power electric strips - in conjunction with occupancy sensors to power down computer equipment when left unattended for extended periods of time.

APPENDIX E: GLOSSARY AND METHOD OF CALCULATIONS Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically the total cost (materials + labor) of installing the measure minus any available incentives. Both the total cost and the incentive amounts are expressed in the summary for each ECM. Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the calculated energy savings (kWh or Therm) of each ECM and the calculated energy costs of the building. Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired, this value can factor in an annual increase in energy costs as long as the source is provided. Simple Payback: This is a simple measure that displays how long the ECM will take to breakeven based on the annual energy and maintenance savings of the measure. ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM will be in place and whether or not it will exceed the simple payback period. Additional guidance for calculating ECM lifetimes can be found below. This value can come from manufacturer’s rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source. Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It is the difference in the operating, maintenance, and / or equipment replacement costs of the existing case versus the ECM. In the case where an ECM lifetime will be longer than the existing measure (such as LED lighting versus fluorescent) the operating savings will factor in the cost of replacing the units to match the lifetime of the ECM. In this case or in one where one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of the ECM. Return on Investment (ROI): The ROI is expresses the percentage return of the investment based on the lifetime cost savings of the ECM. This value can be included as an annual or lifetime value, or both. Net Present Value (NPV): The NPV calculates the present value of an investment’s future cash flows based on the time value of money, which is accounted for by a discount rate (assumes bond rate of 3.2%). Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even point for the investment. If the owner is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the owner to compare ECMs against each other to determine the most appealing choices. Gas Rate and Electric Rate ($/therm and $/kWh): The gas rate and electric rate used in the financial analysis is the total annual energy cost divided by the total annual energy usage for the 12 month billing period studied. The graphs of the monthly gas and electric rates reflect the total monthly energy costs divided by the monthly usage, and display how the average rate fluctuates throughout the year. The average annual rate is the only rate used in energy savings calculations.

* The lifetime operating cost savings are all avoided operating, maintenance, and/or component replacement costs over the lifetime of the ECM. This can be the sum of any annual operating savings, recurring or bulk (i.e. one-time repairs) maintenance savings, or the savings that comes from avoiding equipment replacement needed for the existing measure to meet the lifetime of the ECM (e.g. lighting change outs).
Excel NPV and IRR Calculation In Excel, function =IRR (values) and =NPV (rate, values) are used to quickly calculate the IRR and NPV of a series of annual cash flows. The investment cost will typically be a negative cash flow at year 0 (total cost - incentive) with years 1 through the lifetime receiving a positive cash flow from the annual energy cost savings and annual maintenance savings. The calculations in the example below are for an ECM that saves $850 annually in energy and maintenance costs (over a 10 year lifetime) and takes $5,000 to purchase and install after incentives:

Solar PV ECM Calculation There are several components to the calculation: Costs: Energy Savings: Incentive:
Assumptions:
Material of PV system including panels, mounting and net-metering + Labor Reduction of kWh electric cost for life of panel, 25 years Solar Renewable Energy Credits (SRECs) – Market-rate incentive. Calculations assume $600/Megawatt hour consumed per year for a maximum of 15 years; added to annual energy cost savings for a period of 15 years. (Megawatt hour used is rounded to nearest 1,000 kWh) A Solar Pathfinder device is used to analyze site shading for the building and determine maximum amount of full load operation based on available sunlight. When the Solar Pathfinder device is not implemented, amount of full load operation based on available sunlight is assumed to be 1,180 hours in New Jersey.
Total lifetime PV energy cost savings = kWh produced by panel * [$/kWh cost * 25 years + $600/Megawatt hour /1000 * 15 years] ECM and Equipment Lifetimes Determining a lifetime for equipment and ECM’s can sometimes be difficult. The following table contains a list of lifetimes that the NJCEP uses in its commercial and industrial programs. Other valid sources are also used to determine lifetimes, such as the DOE, ASHRAE, or the manufacturer’s warranty. Lighting is typically the most difficult lifetime to calculate because the fixture, ballast, and bulb can all have different lifetimes. Essentially the ECM analysis will have different operating cost savings (avoided equipment replacement) depending on which lifetime is used. When the bulb lifetime is used (rated burn hours / annual burn hours), the operating cost savings is just reflecting the theoretical cost of replacing the existing case bulb and ballast over the life of the recommended bulb. Dividing by the bulb lifetime will give an annual operating cost savings. When a fixture lifetime is used (e.g. 15 years) the operating cost savings reflects the avoided bulb and ballast replacement cost of the existing case over 15 years minus the projected bulb and ballast replacement cost of the proposed case over 15 years. This will give the difference of the equipment replacement costs between the proposed and existing cases and when divided by 15 years will give the annual operating cost savings.

Township of Raritan – Municipal Building
Page 2/58
EXECUTIVE SUMMARY The Township of Raritan municipal building is a two-story slab on grade building comprising a total conditioned floor area of 34,200 square feet. The original structure was built in 2002, and there have been no major renovations or additions since then. The following chart provides a comparison of the current building energy usage based on the period from December 2009 through November 2010 with the proposed energy usage resulting from the installation of recommended Energy Conservation Measures (ECMs) excluding any renewable energy: Table 1: State of Building—Energy Usage

*Includes operation and maintenance savings; **Includes SRECS
SWA has entered energy information about the residential complex into the U.S. Environmental Protection Agency’s (EPA) Energy Star Portfolio Manager Energy Benchmarking system. The building has an Energy Star Rating of 28 and a Site Energy Utilization of 115 kBtu/sqft/yr. The building equipment appears to be in good condition; however, there was some concern related to building controls and high use of heating gas use during the summer. Recommendations Based on the current state of the building and its energy use, SWA recommends implementing the following Energy Conservation Measures: Table 2: Energy Conservation Measure Recommendations ECMs 0-5 Year 5-10 Year >10 year Total Proposed Renewable Energy
First Year Savings ($) $2,643 $3,950 $12,209 $18,801 $12,209
Simple Payback Period 3.3 0.6 11.5 8.0 11.5
Initial Investment ($) $8,849 $2,399 $140,000 $151,248 $140,000
CO2 Savings (lbs/yr) 27,884 127,514 42,256 197,654 42,256
In addition to these ECMs, SWA recommends: •
•
Capital Investment opportunities – measures that would contribute to reducing energy usage but require significant capital resources as well as long-term financial planning o Install a new Direct Digital Control (DDC) Building Automation System (BAS) o Modify ducting system in Toilet and Lunch room areas Operation and Maintenance (O&M) measures that would contribute to reducing energy usage at low cost – not cost o Clean and maintain gutters, downspouts and downspout deflectors o Maintain weather-stripping around all exterior doors and roof hatches
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 3/58
There may be energy procurement opportunities for the Township of Raritan to reduce annual electricity costs, which are $7,471 higher, when compared to the average estimated NJ commercial electricity rates. SWA recommends further negotiation with energy suppliers, listed in Appendix D. Environmental Benefits SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 16 cars from the roads each year or is equivalent of planting 481 trees to absorb CO 2 from the atmosphere. Energy Conservation Measure Implementation Based on the requirements of the Local Government Energy Audit (LGEA) program, the Township of Raritan must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report’s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit per building. The minimum amount to be spent, net of other NJCEP incentives, is $1,987. SWA recommends that the Township of Raritan implement the following Energy Conservation Measures using an appropriate Incentive Programs for reduced capital cost: Recommended ECMs Install 37 Occupancy sensors Retrofit the vending machines with VendingMisers Add a new condensing boiler Retro-commission the HVAC systems Install a 20kW PV system

INTRODUCTION Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, ‘whole building’ strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the municipal building at 1 Municipal Drive, Flemington. The process of the audit included facility visits on February 4th, 2011, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and other recommendations for improvements. The scope of work includes providing a summary of current building conditions, current operating costs, potential savings, and investment costs to achieve these savings. The facility description includes energy usage, occupancy profiles and current building systems along with a detailed inventory of building energy systems, recommendations for improvement and recommendations for energy purchasing and procurement strategies. The goal of this Local Government Energy Audit is to provide sufficient information to the Township of Raritan to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures for the Municipal building.

HISTORICAL ENERGY CONSUMPTION Energy usage, load profile and cost analysis SWA reviewed utility bills from January 2009 through December 2010 that were received from the utility companies supplying the municipal building with electric and natural gas. A 12 month period of analysis from December 2009 through November 2010 was used for all calculations and for purposes of benchmarking the building. Electricity - The municipal building is currently served by one electric meter. The municipal building currently buys electricity from JCP&L at an average aggregated rate of $0.166/kWh and consumed approximately 453,480 kWh, or $75,493 worth of electricity, in the previous year. The average monthly demand was 111.3 kW and the annual peak demand was 130.6 kW. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate baseload or minimum electric usage required to operate the municipal building.
Natural gas - The municipal building is currently served by one meter for natural gas. The municipal building currently buys natural gas from Elizabethtown Gas Co. at an average aggregated rate of $1.075/therm and consumed approximately 23,977 therms, or $25,764 worth of natural gas, in the previous year. The chart below shows the monthly natural gas usage and costs. The green line represents the approximate baseload or minimum natural gas usage required to operate the municipal building.

The chart above shows the monthly natural gas usage along with the heating degree days or HDD. Heating degree days is the difference of the average daily temperature and a base temperature, on a particular day. The heating degree days are zero for the days when the average temperature exceeds the base temperature. SWA’s analysis used a base temperature

of 65 degrees Fahrenheit. This chart shows that the gas used curve does not follow the HDD curve during the summer months and that there is considerable gas used for building heating even during the summer. The following graphs, pie charts, and table show energy use for the Municipal building based on utility bills for the 12 month period.

Energy benchmarking SWA has entered energy information about the municipal building in the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system. This municipal building is categorized as an office facility space type and is eligible to receive a national energy performance rating. The present benchmarking score of the building is 28. The Site Energy Use Intensity is 115 kBtu/sqft/yr compared to the national average of an office
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 8/58
building consuming 91 kBtu/sqft/yr. See ECM section for guidance on how to improve the building’s rating. Additionally, should the municipality desire to better this average, there are other large scale and financially less advantageous improvements that can be made, such as large scale HVAC upgrades.
Per the LGEA program requirements, SWA has assisted the Township of Raritan to create an ENERGY STAR® Portfolio Manager account and share the municipal building facilities information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Township of Raritan (user name of “RaritanTownship” with a password of “RaritanTownship”) and TRC Energy Services (user name of “TRC-LGEA”). Tariff analysis Tariff analysis can help determine if the municipality is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Natural gas prices often increase during winter months since large volumes of natural gas is needed for heating. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the Township of Raritan. The Municipal building is currently paying a general service rate for natural gas including fixed costs such as meter reading charges. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on

electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Energy Procurement strategies Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electricity are $0.150/kWh, while the municipal building pays a rate of $0.166/kWh. The municipal building annual electric utility costs are $7,471 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 7% over the most recent 12 month period.
Electric rate fluctuations follow the expected pattern with a peak during the summer, drop-offs in the shoulder months and a small rise in the winter due to the high energy rates. The average estimated NJ commercial utility rates for gas are $1.550/therm, while municipal building pays a rate of $1.075/therm. Natural gas bill analysis shows fluctuations up to 38% over the most recent 12 month period.
Steven Winter Associates, Inc. - LGEA Report

Page 10/58
Natural Gas rate fluctuations may have been caused by fixed fees and costs assessed during the summer months when usage is at a minimum. SWA recommends that the municipal building further explore opportunities of purchasing both natural gas and electricity from third-party suppliers in order to reduce rate fluctuation and ultimately reduce the annual cost of energy for the municipal building. Appendix C contains a complete list of third-party energy suppliers for the Township of Raritan service area.

Building Envelope Due to favorable weather conditions (min. 18 deg. F delta-T in/outside and no/low wind), some exterior envelope infrared (IR) images were taken during the field audit. IR technology helps to identify energy-compromising problem areas in a non-invasive way. Exterior Walls The exterior wall envelope is mostly constructed of 6” 16 Gauge metal stud wall with a 5/8” concrete board to its exterior and either a 2” stone veneer or precast concrete finish with 4 inches of fiberglass batt cavity insulation. There are also some sections constructed of 2” EIFS with either concrete masonry units or metal stud walls to its interior with R-19 fiberglass batt insulation. Note: Wall insulation levels could not be verified in the field and are based on available construction plans. Exterior and interior wall surfaces were inspected during the field audit. They were found to be in overall good condition with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. The following specific exterior wall problem spots and areas were identified:
Typical wall surfaces with some signs of uncontrolled roof water runoff on walls due to defective roof flashing and damaged and clogged gutters and downspouts.

Base The building’s base is composed of a slab-on-grade floor with a perimeter footing with poured concrete foundation walls and a slab edge/perimeter insulation. Slab/perimeter insulation levels could not be verified in the field and are based on available construction plans. The building’s base and its perimeter were inspected for signs of uncontrolled moisture or water presence and other energy-compromising issues. Overall the base was reported to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energycompromising issues neither visible on the interior nor exterior. Windows The building contains basically two different types of windows. 1. Fixed type windows of different sizes with an insulated aluminum frame, clear double glazing and interior mini blinds. The windows are located throughout the building and are original. 2. Sidelight and transom windows alongside glass doors with an insulated aluminum frame, clear double glazing and no shading. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues.

The following IR images further illustrate the good condition of the existing doors:
Building air-tightness Overall the field auditors found the building to be reasonably air-tight, considering the building's use and occupancy, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses. Mechanical Systems Heating Ventilation Air Conditioning The Municipal Building is fully heated and cooled. There were no major comfort related complaints from the building occupants. A minor complaint noted was regarding lack of temperature control arising due to lack of air movement in one of the toilets. Equipment The Municipal Building contains four indoor heating/cooling packaged units, hot water boilers, a chiller, pumps, and ventilation fans. A comprehensive Equipment List can be found in Appendix A. The building contains four Trane air handling units (AHUs) equipped with chilled and hot water coils for cooling and heating the building. The units are equipped with supply and return air fans, both controlled by variable frequency drives (VFD). The fan motors were all NEMA premium efficiency motors and the VFDs were seen to be operating fine. For example, VFD for unit AC-1 supply was seen at 36.1Hz, for unit AC-2 supply at 41.7 Hz, and for unit AC-3 at 43.8Hz. All the units were installed in 2002 and have about 60% of service life remaining and appeared to be in good condition. The heating hot water is produced by five (5) gas-fired, Slant/Fin, Galaxy hot water boilers located in the Mechanical room. The boilers are rated for 399MBH input each and have an estimated 81% thermal efficiency. The boilers were installed in 2002 and have about 68% of remaining usable service life of a small commercial boiler of 20 years according to the LGEA

equipment lifespan guidelines. The boilers appear to be in good condition ion as seen in the picture below.
Slant/Fin boilers – appear to be in good condition Chilled water is provided to various air handling units from one 125 ton air cooled Trane chiller located outside on grade. The chiller was installed in 2002 and is in good condition. It is rated for 10.5 EER at full load, and 9.8 EER at full load. The chiller still has about 68% of useful life remaining.
Trane Air cooled chiller There are five exhaust fans which exhaust air from the bathrooms and the kitchen areas of the building. The fans appeared to be in good condition and had about 47% of their service life remaining.

Distribution Systems The air is delivered to various spaces within the building using distribution ducts. There are terminal variable air volume (VAV) boxes. The building is divided into four main zones, and each zone is served by a central Trane air handling unit. The return air is either fed back into the unit or exhausted out of the building. Hot water is distributed to the air handling units and to the VAV boxes by a hot water pipe distribution system. There are two hot water pumps and only one pump works at a time; other remains on the standby. Each pump is equipped with a 7.5hp NEMA premium efficiency motor. Chilled water is distributed to the air handling units by a chilled water pipe distribution system. There are two chilled water pumps and only one pump works at a time; other remains on the standby. Each pump is equipped with a 7.5hp NEMA premium efficiency motor.
Hot water pumps
Chilled water pumps
Controls There is no central building management system for equipment controls. The main equipment like chillers, boilers, air handling units, etc. are controlled from local, stand alone, dedicated controls systems. These local controls systems don’t seem to communicate with each other effectively. The boilers are controlled by a wall mounted controls system manufactured and installed by Tekmar controls. It regulates supply water temperature based on outside air temperature or through indoor air temperature through a 10K zone control. The system pump is turned on when there is a heat demand and the outdoor temperature is cool enough to require heat into the system in the winter. There is an internal timer to program schedules for occupied and unoccupied modes settings. Each air handling unit has a standalone controls system with a time clock, which is individually set for occupied and unoccupied modes. The morning warm up schedule is initiated in going from unoccupied to occupied mode. Supply and return fans are equipped with variable frequency drives, which control the fan speed based on the duct mounted pressure sensor signal. The duct distribution system comprises variable air volume boxes
Steven Winter Associates, Inc. - LGEA Report

Page 19/58
serving various spaces. The discharge air controller uses the enthalpy based economizers to vary the ventilation air in the shoulder seasons. During unoccupied modes, the supply fan and return fans are shut down and there is no ventilation; supply fans turn on only if the night set back temperature signal demand for more heat. The VAV box is connected to its own thermostat and maintains air flow in the space to control the temperature and ventilation.
Boilers control
Variable Frequency Drive
VAV thermostat
Chiller is programmed to run if the outside air temperature rises above 60 deg F. The chiller and the chilled water pumps are interlocked. Based on the utility bill analysis there is natural gas heating used in the VAV hot water coils from May to November, and this would be considered a wasteful use of energy inherent with these types of HVAC systems employing VAVs. There is no simple solution to deal with this situation – some building users simply shut down the boilers in the summer time and rely on the occupants to war warm clothing if the room feels cold. Domestic Hot Water The domestic hot water (DHW) for the Municipal Building is provided by two AO Smith natural gas heaters. One DHW is of 30 gallons storage and rated for 32 MBH input, and the other is of 50 gallons storage and rated for 42MBH input. Both are estimated to have an efficiency of 80% and were installed in 2002. They have about 38% of remaining service life.

Electrical systems Lighting See attached lighting schedule in Appendix B for a complete inventory of lighting throughout the building including estimated power consumption and proposed lighting recommendations. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July 2012. Interior Lighting - The municipal building currently contains mostly T8 lamped electronically ballasted fixtures and self-ballasted compact fluorescent lamps. There are also a few incandescent self-ballasted lamps in the courtroom and offices. Based on measurements of lighting levels for each space, there are no vastly over-illuminated areas. Exit Lights - Exit signs were found to be of the LED type. Exterior Lighting - The exterior lighting surveyed during the building audit was found to be a mix of metal halide lamp and incandescent fixtures. Exterior lighting is controlled by automatic timers.
Appliances and process SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as “plug-load” equipment, since they are not inherent to the building’s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building’s energy usage based on utility analysis. There are two older model refrigerated vending machines that SWA recommends to be retrofitted VendingMiser® devices. Also installed at the municipal building is a newer model Frigidaire manufactured refrigerator that should remain and two older model Summit manufactured refrigerators that should be replaced with new Energy Star certified units.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES Renewable energy is defined as any power source generated from sources which are naturally replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving and the cost of installation is decreasing due to both demand and the availability of governmentsponsored funding. Renewable energy reduces the need for using either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased from the utility company. Solar photovoltaic panels and wind turbines use natural resources to generate electricity. Geothermal systems offset the thermal loads in a building by using water stored in the ground as either a heat sink or heat source. Cogeneration or Combined Heat and Power (CHP) allows for heat recovery during electricity generation. Existing systems Currently there are no renewable energy systems installed in the building. Evaluated Systems Solar Photovoltaic Photovoltaic panels convert light energy received from the sun into a usable form of electricity. Panels can be connected into arrays and mounted directly onto building roofs, as well as installed onto built canopies over areas such as parking lots, building roofs or other open areas. Electricity generated from photovoltaic panels is generally sold back to the utility company through a net meter. Net-metering allows the utility to record the amount of electricity generated in order to pay credits to the consumer that can offset usage and demand costs on the electric bill. In addition to generation credits, there are incentives available called Solar Renewable Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the municipal building is a good candidate for a 20 kW Solar Panel installation. See ECM#9 for details. Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure. Wind The municipal building is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The municipal building is not a good candidate for geothermal installation since it would require replacement of the entire existing HVAC system, of which major components still have between 30% and 70% remaining useful life.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – Municipal Building
Page 23/58
Combined Heat and Power The municipal building is not a good candidate for CHP installation and would not be costeffective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently.

ECM#3: Install thirty-seven (37) new occupancy sensors On the days of the site visits, SWA completed a lighting inventory of the Township of Raritan Municipal Building (see Appendix B). The building contains twenty areas that could benefit from the installation of occupancy sensors. These areas consisted of various meeting rooms and offices that are used sporadically throughout the day and could show energy savings by having the lights turn off after a period of no occupancy. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advanced micro-phonic lighting sensors include sound detection as a means to controlling lighting operation.

ECM#4: Replace two (2) refrigerators with 18 cu. ft. ENERGY STAR® models On the day of the site visit, SWA observed that there were two older refrigerators, 18 cu. ft. models in the building which were not Energy Star rated (using approximately 380 kWh/year). Appliances, such as refrigerators, that are over 10 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerators with a 18 cu. ft. ENERGY STAR® refrigerator. Besides saving energy, the replacement will also keep their surroundings cooler. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

ECM #5: Add a new lead Condensing Gas Boiler The heating hot water is produced by five (5) gas-fired, Slant/Fin, Galaxy hot water boilers located in the Mechanical room. The boilers are rated for 399MBH input each and have an estimated 81% thermal efficiency. The boilers were installed in 2002 and appear to be in good condition. The utility bill analysis shows that the boilers are used throughout the year because of the demand for hot water in VAV reheat coils during summer. In this light, SWA recommends adding a 300 MBH boiler of higher efficiency. The new boiler will become the lead boiler and work to meet 85% or more of the regular heating load. The back up boilers would fire only in extreme weather and for any emergencies. Condensing boilers allow condensation of moisture in flue gases resulting in lower flue gas temperatures with increased efficiencies up to 95%. The new high efficiency condensing boilers should have a guaranteed minimum thermal efficiency of 85% and efficiencies of up to 95% achievable during condensing mode at lower return water temperatures.

There may be energy procurement opportunities for the Township of Raritan to reduce annual utility costs, which are $2,313 higher, when compared to the average estimated NJ commercial utility rates. SWA recommends further negotiation with energy suppliers listed in Appendix C. Environmental Benefits SWA estimates that implementing the recommended ECMs is equivalent to removing approximately 3 cars from the roads each year or is equivalent of planting 88 trees to absorb CO 2 from the atmosphere. Energy Conservation Measure Implementation Based on the requirements of the Local Government Energy Audit (LGEA) program, the Township of Raritan must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report’s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit per building. The minimum amount to be spent, net of other NJCEP incentives, is 1,468. SWA recommends that the Township of Raritan implement the following Energy Conservation Measures using an appropriate Incentive Programs for reduced capital cost: Recommended ECMs Replace T12 light fixtures with T8 Replace existing domestic water heater Install occupancy sensors Install programmable thermostat with controller Install a 20kW PV system

INTRODUCTION Launched in 2008, the Local Government Energy Audit (LGEA) Program provides subsidized energy audits for municipal and local government-owned facilities, including offices, courtrooms, town halls, police and fire stations, sanitation buildings, transportation structures, schools and community centers. The Program will subsidize up to 100% of the cost of the audit. The Board of Public Utilities (BPUs) Office of Clean Energy has assigned TRC Energy Services to administer the Program. Steven Winter Associates, Inc. (SWA) is a 38-year-old architectural/engineering research and consulting firm, with specialized expertise in green technologies and procedures that improve the safety, performance, and cost effectiveness of buildings. SWA has a long-standing commitment to creating energy-efficient, cost-saving and resource-conserving buildings. As consultants on the built environment, SWA works closely with architects, developers, builders, and local, state, and federal agencies to develop and apply sustainable, ‘whole building’ strategies in a wide variety of building types: commercial, residential, educational and institutional. SWA performed an energy audit and assessment for the Public Works Department Building at 1 Municipal Drive, Flemington. The process of the audit included facility visits on February 4th, 2011, benchmarking and energy bills analysis, assessment of existing conditions, energy modeling, energy conservation measures and other recommendations for improvements. The scope of work includes providing a summary of current building conditions, current operating costs, potential savings, and investment costs to achieve these savings. The facility description includes energy usage, occupancy profiles and current building systems along with a detailed inventory of building energy systems, recommendations for improvement and recommendations for energy purchasing and procurement strategies. The goal of this Local Government Energy Audit is to provide sufficient information to the Township of Raritan to make decisions regarding the implementation of the most appropriate and most costeffective energy conservation measures for the Public Works Department Building.

HISTORICAL ENERGY CONSUMPTION Energy usage, load profile and cost analysis SWA reviewed utility bills from January 2009 through December 2010 that were received from the utility companies supplying the Public Works Department Building with electric and propane. A 12 month period of analysis from December 2009 through November 2010 was used for all calculations and for purposes of benchmarking the building. Electricity - The Public Works Department Building is currently served by one electric meter. The Public Works Department Building currently buys electricity from JCP&L at an average aggregated rate of $0.153/kWh and consumed approximately 154,707 kWh, or $23,641 worth of electricity, in the previous year. The average monthly demand was 44.1 kW and the annual peak demand was 47.5 kW. The chart below shows the monthly electric usage and costs. The dashed green line represents the approximate baseload or minimum electric usage required to operate the Public Works Department Building.
Propane - The Public Works Department Building is currently served by one meter for propane. The Public Works Department Building currently buys propane from the Suburban Propane Company at an average aggregated rate of $2.304/gallon and consumed approximately 6,174 gallons, or $14,225 worth of propane, in the previous year. The chart below shows the monthly propane usage and costs. The green line represents the approximate baseload or minimum propane usage required to operate the Public Works Department Building.

The following graphs, pie charts, and table show energy use for the Public Works Department building based on utility bills for the 12 month period. Note that the electricity cost at $45/MMBtu of energy is almost 3 times as expensive as propane at $17/MMBtu.
Energy benchmarking SWA entered the energy information about the Public Works Department Building in the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Portfolio Manager Energy benchmarking system. This Public Works Department Building is categorized as an “other service” facility space type and was not eligible to receive a national energy performance rating. The Site Energy Use Intensity is 57 kBtu/sqft/yr compared to the national average of an “other – service” building consuming 104 kBtu/sqft/yr. See ECM section for guidance on how to improve the building’s rating. Additionally, should the municipality desire to reach this average there are other large scale and financially less advantageous improvements that can be made, such as envelope window, door and insulation upgrades that would help the building reach this goal.

Per the LGEA program requirements, SWA has assisted the Township of Raritan to create an ENERGY STAR® Portfolio Manager account and share the Public Works Department Building facilities information to allow future data to be added and tracked using the benchmarking tool. SWA has shared this Portfolio Manager account information with the Township of Raritan (user name of “RaritanTownship” with a password of “RaritanTownship”) and TRC Energy Services (user name of “TRC-LGEA”). Tariff analysis Tariff analysis can help determine if the municipality is paying the lowest rate possible for electric and gas service. Tariffs are typically assigned to buildings based on size and building type. Rate fluctuations are expected during periods of peak usage. Propane prices often increase during winter months since large volumes of propane are needed for heating equipment. Similarly, electricity prices often increase during the summer months when additional electricity is needed for cooling equipment. As part of the utility bill analysis, SWA evaluated the current utility rates and tariffs for the Township of Raritan. The electric use for the building is direct-metered and purchased at a general service rate with an additional charge for electrical demand factored into each monthly bill. The general service rate is a market-rate based on electric usage and electric demand. Demand prices are reflected in the utility bills and can be verified by observing the price fluctuations throughout the year. Energy Procurement strategies Billing analysis was conducted using an average aggregated rate which is estimated based on the total cost divided by the total energy usage for each utility over a 12 month period. Average aggregated rates do not separate demand charges from usage, and instead provide a metric of

Page 9/50
inclusive cost per unit of energy. Average aggregated rates are used in order to equitably compare building utility rates to average utility rates throughout the state of New Jersey. The average estimated NJ commercial utility rates for electric are $0.150/kWh, while the Public Works Department Building pays a rate of $0.153/kWh. The Public Works Department Building annual electric utility costs are $435 higher, when compared to the average estimated NJ commercial utility rates. Electric bill analysis shows fluctuations up to 12% over the most recent 12 month period. Electric rate fluctuations follow the expected pattern with a peak during the summer, drop-offs in the shoulder months and a small rise in the winter due to the high energy rates.
The average estimated NJ commercial utility rates for propane are $2.00/gallon, while Public Works Department Building pays a rate of $2.304/gallon. The Public Works Department Building annual propane costs are $1,878 higher, when compared to the average estimated NJ commercial utility rates. Propane bill analysis shows fluctuations up to 37% over the most recent 12 month period. Propane rate fluctuations may have been caused by fixed fees and costs assessed during the summer months when usage is at a minimum. SWA compared the cost of Propane to the cost of Natural gas as follows: on a per therm basis, the cost of propane works out to $1.70/therm, whereas the average New Jersey gas rates are about $1.5/therm. The Public Works Department pays about 15% more than it would have paid had it been served with natural gas, based on the average prevailing New Jersey rates.

EXISTING FACILITY AND SYSTEMS DESCRIPTION This section gives an overview of the current state of the facility and systems. Please refer to the Proposed Further Recommendations section for recommendations for improvement. Based on visits from SWA on Friday, February 04, 2011, the following data was collected and analyzed. Building Characteristics The single story, slab on grade, 24,000 square feet public works facility was originally constructed in 1986. It houses administration offices, locker rooms, garage spaces and various work stations.
Partial Southwest Façade
Partial Southeast Façade
Partial Northeast Façade
Partial Northwest Façade
Building Occupancy Profiles Its occupancy is approximately 27 employees daily from 7:30 to 3:30 Monday through Friday and as necessary based on emergency conditions. Building Envelope Due to favorable weather conditions (min. 18 deg. F delta-T in/outside and no/low wind), some exterior envelope infrared (IR) images were taken during the field audit. IR technology helps to identify energy-compromising problem areas in a non-invasive way.

Exterior Walls The exterior wall envelope is mostly constructed of exposed and painted CMU (Concrete Masonry Unit) and some CMU (Concrete Masonry Unit) with fluted brick finish. No insulation was recorded. The interior is mostly exposed CMU (Concrete Masonry Unit) and painted gypsum wallboard. Note: Wall insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction. Exterior and interior wall surfaces were inspected during the field audit. They were found to be in overall good condition with only a few signs of uncontrolled moisture, air-leakage or other energy-compromising issues detected on all facades. The following specific exterior wall problem spots and areas were identified:
Cracked caulk, shifted brick, signs of water damage and uncontrolled roof water runoff due to damaged gutters.
The following IR images further demonstrate the condition of the exterior walls:

Roof The building has a three tier roof with one above the offices and two above the garage. All three are predominantly a flat or slightly sloped, no parapet type over steel decking, with a light-colored EPDM single-membrane finish. It is original with three and a half inches of roof insulation. Note: Roof insulation levels could not be verified in the field, and are based on available construction plans. Roofs, related flashing, gutters and downspouts were inspected during the field audit. They were reported to be in overall good condition, with no signs of uncontrolled moisture, airleakage or other energy-compromising issues detected on all roof areas. The following typical roof systems were identified:
Typical roof systems. Base The building’s base is composed of a slab-on-grade floor with a perimeter foundation and no detectable slab edge/perimeter insulation. Slab/perimeter insulation levels could not be verified in the field or on construction plans, and are based upon similar wall types and time of construction.

The building’s base and its perimeter were inspected for signs of uncontrolled moisture or water presence and other energy-compromising issues. Overall the base was reported to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energycompromising issues neither visible on the interior nor exterior. Windows The building contains basically three different types of windows. 1. Unit (fixed and hopper) type windows with a non-insulated aluminum frame, clear single glazing and no interior or exterior shading devices. The windows are located throughout the building and are original. 2. Slider type windows with a non-insulated aluminum frame, clear double glazing and no interior or exterior shading devices. The windows are located in the sign room mezzanine only. 3. Typical transom and sidelight windows alongside the glass doors. Windows, shading devices, sills, related flashing and caulking were inspected as far as accessibility allowed for signs of moisture, air-leakage and other energy compromising issues. Overall, the windows were found to be in good condition with no signs of uncontrolled moisture, air-leakage and/ or other energy-compromising issues. The following specific window problem spots were identified:
Typical exterior windows. Exterior doors The building contains several different types of exterior doors. 1. Solid metal type exterior doors. They are located throughout the building and are original. 2. Overhead aluminum type exterior doors with glass panels. They are located throughout the garage areas and are original. 3. Glass with aluminum/steel frame type exterior doors. They are located on the north façade at the main entrance. All exterior doors, thresholds, related flashing, caulking and weather-stripping were inspected for signs of moisture, air-leakage and other energy-compromising issues. Overall, the doors were found to be in good condition with no signs of uncontrolled moisture, airleakage and/ or other energy-compromising issues.

The following specific door problem spots were identified:
Typical exterior doors. Building air-tightness Overall the field auditors found the building to be reasonably air-tight, considering the building's use and occupancy, as described in more detail earlier in this chapter. The air tightness of buildings helps maximize all other implemented energy measures and investments, and minimizes potentially costly long-term maintenance, repair and replacement expenses. Mechanical Systems Heating Ventilation Air Conditioning The DPW Building is fully heated and only partly cooled. There were no major comfort related complaints from the building occupants. Equipment The DPW Building contains two roof mounted packaged units, nine propane fired unit heaters, an infra-red heating tube, and ventilation fans. A comprehensive Equipment List can be found in Appendix A.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 16/50
The rooftop units contain a propane fired burner for heating and a direct expansion (DX) system for cooling, made up of an evaporator, condenser and refrigerant loop. The units were manufactured by York and installed around 2005. The units have about 60% remaining life and appear to be in good condition. The packaged units are rated for 9 EER in efficiency. Considering that the current units still have a good amount of useful service life remaining, SWA does not recommend replacing these units with higher efficiency units in the near future due to economic considerations. The units consist of a down flow enthalpy controlled economizer which varies the outside air quantity based on the outside air temperature.
Roof top packaged units – appear to be in good condition The DPW building contains areas that are heated only by propane fired ceiling hung unit heaters. There is a small unit heater for the “Sign Shop”; there is one small unit heater serving the “Wash Bay”; and there are seven relatively larger unit heaters installed in the “Storage Garage”. The Wash Bay heater was found to be in non-working condition, and so were four of the heaters in the Storage Garage. The Shop area was also equipped with an overhead infra red heating tube manufactured y CoRayVac. The office type spaces of the building are provided ventilation by outside air intake louvers on the rooftop units. The outside air louvers are motorized to allow economizer operation when the outside air conditions are favorable. The shop floor is provided ventilation by means of various exhaust fans. SWA noted that most of the ventilation fans were operating beyond the service life of a ventilation fan of 10 years. Distribution Systems The air is delivered to various spaces within the building using distribution ducts. There are supply and return air ducts terminating at the roof top packaged units. The exhaust air is either returned back or exhausted using the unit power exhauster. The supply air is a mixture of returned air and fresh air. Supply air is either heated or cooled depending on the space thermostat setting and requirement. Controls Roof top packaged units are controlled from individual programmable thermostats. The thermostats seemed to be programmed for night set backs during the winter months. There is no central building management system for equipment controls. The unit heaters are mostly controlled by manual thermostats of two types as show below. Various exhaust fans are switch operated and turned on manually if required.

Page 17/50
Programmable Thermostats for RTU; Non programmable ones for unit heaters Domestic Hot Water The domestic hot water (DHW) for the DPW Building is provided by one large heater. There is one propane fired heater with 250 gallons storage and rated for 243 MBH input and an estimated 70% efficiency. The heater was installed in 1985 and is operating well beyond its estimated service life of 13 years, and looks like it is badly in need of replacement.
Domestic Hot Water Heater Electrical systems Lighting See attached lighting schedule in Appendix B for a complete inventory of lighting throughout the building including estimated power consumption and proposed lighting recommendations. As of July 1, 2010 magnetic ballasts most commonly used for the operation of T12 lamps will no longer be produced for commercial and industrial applications. Also, many T12 lamps will be phased out of production starting July 2012.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 18/50
Interior Lighting - The Public Works Department Building currently contains mostly T12 lamped magnetically ballasted fixtures and self-ballasted compact fluorescent lamps. There are also high bay metal halide and high pressure sodium lamped fixtures. Based on measurements of lighting levels for each space, there are no vastly over-illuminated areas. Exit Lights - Exit signs were found to be a mixture of the LED and incandescent type. Exterior Lighting - The exterior lighting surveyed during the building audit was found to be high pressure sodium lamped fixtures. Exterior lighting is controlled by automatic timers.
Appliances and process SWA has conducted a general survey of larger, installed equipment. Appliances and other miscellaneous equipment account for a significant portion of electrical usage within the building. Typically, appliances are referred to as “plug-load” equipment, since they are not inherent to the building’s systems, but rather plug into an electrical outlet. Equipment such as process motors, computers, computer servers, radio and dispatch equipment, refrigerators, vending machines and printers all create an electrical load on the building that is hard to separate out from the rest of the building’s energy usage based on utility analysis. There is one older model refrigerated vending machine that SWA recommends to be retrofitted with VendingMiser® devices. Also installed at the Public Works Department Building are two older model refrigerators that should be replaced with new Energy Star certified units. One of those units is a large 17 cubic foot unit and the other is a compact unit. Elevators The Public Works Department Building does not have an installed elevator. Other electrical systems There is no significant energy-impacting electrical systems installed at the Public Works Department Building.

RENEWABLE AND DISTRIBUTED ENERGY MEASURES Renewable energy is defined as any power source generated from sources which are naturally replenished, such as sunlight, wind and geothermal. Technology for renewable energy is improving and the cost of installation is decreasing due to both demand and the availability of governmentsponsored funding. Renewable energy reduces the need for using either electricity or fossil fuel, therefore lowering costs by reducing the amount of energy purchased from the utility company. Solar photovoltaic panels and wind turbines use natural resources to generate electricity. Geothermal systems offset the thermal loads in a building by using water stored in the ground as either a heat sink or heat source. Cogeneration or Combined Heat and Power (CHP) allows for heat recovery during electricity generation. Existing systems Currently there are no renewable energy systems installed in the building. Evaluated Systems Solar Photovoltaic Photovoltaic panels convert light energy received from the sun into a usable form of electricity. Panels can be connected into arrays and mounted directly onto building roofs, as well as installed onto built canopies over areas such as parking lots, building roofs or other open areas. Electricity generated from photovoltaic panels is generally sold back to the utility company through a net meter. Net-metering allows the utility to record the amount of electricity generated in order to pay credits to the consumer that can offset usage and demand costs on the electric bill. In addition to generation credits, there are incentives available called Solar Renewable Energy Credits (SRECs) that are subsidized by the state government. Specifically, the New Jersey State government pays a market-rate SREC to facilities that generate electricity in an effort to meet state-wide renewable energy requirements. Based on utility analysis and a study of roof conditions, the Public Works Department Building is a good candidate for a 20 kW Solar Panel installation. See ECM#6 for details. Solar Thermal Collectors Solar thermal collectors are not cost-effective for this building and would not be recommended due to the insufficient and intermittent use of domestic hot water throughout the building to justify the expenditure. Wind The Public Works Department Building is not a good candidate for wind power generation due to insufficient wind conditions in this area of New Jersey. Geothermal The Public Works Department Building is not a good candidate for geothermal installation since only part of the building is cooled year round, making the geothermal system uneconomical to install.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 20/50
Combined Heat and Power The Public Works Department Building is not a good candidate for CHP installation and would not be cost-effective due to the size and operations of the building. Typically, CHP is best suited for buildings with a high electrical baseload to accommodate the electricity generated, as well as a means for using waste heat generated. Typical applications include buildings with an absorption chiller, where waste heat would be used efficiently.

ECM#1: Install one (1) VendingMiser™ devices on refrigerated vending machines Energy vending miser devices are now available for conserving energy used by beverage vending machines and coolers. There isn’t a need to purchase new machines to reduce operating costs and greenhouse gas emissions. When equipped with the vending miser devices, refrigerated beverage vending machines use less energy and are comparable in daily energy performance to new ENERGY STAR® qualified machines. Vending miser devices incorporate innovative energy-saving technology into small plug-and-play devices that installs in minutes, either on the wall or on the vending machine.

ECM#2: Install one hundred and fourteen (114) new T12 toT8 retrofit kits On the day of the site visit, SWA completed a lighting inventory of the Raritan Department of Public Works Building (see Appendix B). The existing lighting inventory contained one hundred and fourteen inefficient T12 fluorescent fixtures with magnetic ballasts. SWA recommends replacing each existing fixture with more efficient T8 fluorescent fixtures with electronic ballasts through retrofit kits. Retrofitted T8 fixtures with electronic ballasts provide equivalent or better light output while reducing energy consumption by 30% when compared to a T12 fixture with magnetic ballast.

ECM# 3: Install two (2) new occupancy sensors On the days of the site visits, SWA completed a lighting inventory of the Township of Raritan Public Works Department Building (see Appendix B). The building contains two areas that could benefit from the installation of occupancy sensors. These areas are the lunch room and an office that are used sporadically throughout the day and could show energy savings by having the lights turned off after a period of no occupancy. Typically, occupancy sensors have an adjustable time delay that shuts down the lights automatically if no motion is detected within a set time period. Advanced micro-phonic lighting sensors include sound detection as a means to controlling lighting operation.

ECM#4: Replace one (1) large refrigerator with 18 cu. ft. ENERGY STAR® model On the day of the site visit, SWA observed that there was one older refrigerator, 17 cu. ft. model in the building which were not Energy Star rated (using approximately 773 kWh/year). Appliances, such as refrigerators, that are over 10 years of age should be replaced with newer efficient models with the Energy Star label. SWA recommends the replacement of the existing refrigerators with a 17 cu. ft. top freezer ENERGY STAR® refrigerator. Besides saving energy, the replacement will also keep their surroundings cooler. When compared to the average electrical consumption of older equipment, Energy Star equipment results in large savings. Look for the Energy Star label when replacing appliances and equipment, including: window air conditioners, refrigerators, printers, computers, copy machines, etc. More information can be found in the “Products” section of the Energy Star website at: http://www.energystar.gov.

ECM#5: Install (1) New Thermostats along with Controller There are two propane fired DX roof top package units serving the building, which are controlled from individual programmable thermostats. One of the units serves the Administration offices and the other unit serves the Mezzanine office/shop. Both the thermostats are programmed for occupied and unoccupied modes, separately for summer and winter operations. SWA noted that the Mezzanine area has a variable occupancy pattern, and there may be extended period of times with no occupancy at all. SWA proposes occupancy sensor based temperature settings to cut down energy usage. SWA proposes that the building install (1) new programmable thermostat, a new central controller that can be programmed infinitely from a computer, an outside air stat, and new control wiring. In the new proposed settings, the Mezzanine HVAC packaged units mentioned above would operate at a minimum setting and remain off during unoccupied hours in summer and shoulder seasons. The new thermostat would be wired into the controller and receive the schedule from here. The settings would revert to occupied mode settings on receiving an occupancy signal, and remain in the setting when the occupants are detected. The proposed temperature settings are as follows:
Proposed settings
Summer Occupied Unoccupied 78F Off
Winter Occupied Unoccupied 68F 62F
Shoulder Occupied Unoccupied 72F Off

ECM#6: Install 20 kW Photovoltaic System Currently, the Public Works Department Building does not use any renewable energy systems. Renewable energy systems such as photovoltaic (PV) panels can be mounted on the building roof facing south which can offset a portion of the purchased electricity for the building. Power stations generally have two separate electrical charges: usage and demand. Usage is the amount of electricity in kilowatt-hours that a building uses from month to month. Demand is the amount of electrical power that a building uses at any given instance in a month period. During the summer periods, electric demand at a power station is high, due to the amount of air conditioners, lights, and other equipment being used within the region. Demand charges increase to offset the utility’s cost to provide enough electricity at that given time. Photovoltaic systems offset the amount of electricity used by a building and help to reduce the building’s electric demand, resulting in a higher cost savings. Installing a PV system will offset electric demand and reduce annual electric consumption, while utilizing available state incentives. PV systems are modular and readily allow for future expansions. The size of the system was determined considering the available roof surface area, without compromising service space for roof equipment and safety, as well as the facilities’ annual base load and mode of operation. A commercial multi-crystalline 230 watt panel has 17.5 square feet of surface area (providing 13.1 watts per square foot). A 20 kW system needs approximately 87 panels which would take up 1,523 square feet. A PV system would reduce the building's electric load and allow more capacity for surrounding buildings as well as serve as an example of energy efficiency for the community. The building is not eligible for a residential 30% federal tax credit. The building owner may want to consider applying for a grant and / or engage a PV generator / leaser who would install the PV system and then sell the power at a reduced rate. Typically, a major utility provides the ability to buy SREC’s at $600/MWh or best market offer. However, this option is not available from the local utility. Please see below for more information.

Assumptions: SWA estimated the cost and savings of the system based on past PV projects. SWA projected physical dimensions based on a typical Polycrystalline Solar Panel (230 Watts, Model ND-U23-C1). PV systems are sized based on total wattage and physical dimensions for an array will differ with the efficiency of a given solar panel (W/sq ft). Rebates/financial incentives: • NJ Clean Energy - Solar Renewable Energy Certificate Program. Each time a solar electric system generates 1,000kWh (1MWh) of electricity, a SREC is issued which can then be sold or traded separately from the power. The buildings must also become net-metered in order to earn SRECs as well as sell power back to the electric grid. A total of $13,800/year, based on $600/SREC, has been incorporated in the above costs for a period of 15 years; however it requires proof of performance, application approval and negotiations with the utility.

ECM #9: Replace the existing domestic hot water heater The domestic hot water (DHW) for the DPW Building is provided by one propane fired heater with 250 gallons storage and it is rated for 243 MBH input at an estimated 70% efficiency. The heater was installed in 1985 and SWA recommends replacing the heater with another in kind. The utility bill analysis shows that the DHW is used throughout the year; however, the total DHW usage was estimated to be only 62MMBTu, or about 620 Therms, totaling about $1,041 annually. SWA concludes that the DHW load is not very high and that the heater is sparingly used – and in this light, it becomes clear that converting this heater to a natural gas fired condensing boiler would not be economical. Condensing boilers allow condensation of moisture in flue gases resulting in lower flue gas temperatures with increased efficiencies up to 95%.

PROPOSED FURTHER RECOMMENDATIONS Capital Improvements Capital Improvements are recommendations for the building that may not be cost-effective at the current time, but that could yield a significant long-term payback. These recommendations should typically be considered as part of a long-term capital improvement plan. Capital improvements should be considered if additional funds are made available, or if the installed costs can be shared with other improvements, such as major building renovations. SWA recommends the following capital improvements for the Public Works Department Building: •
Convert the building to natural gas - SWA analyzed that the Public Works Department building pays about 15% more than it would pay had it been served with natural gas, based on the average prevailing New Jersey rates, which works out to about $2,100 annually as the total Propane annual cost is $14,225. The building personnel expressed an interest to convert the building from Propane to Natural gas, and had obtained a quote of about $15,000 to convert all the Propane fired burners to Natural gas. This conversion would work out to about 7 year simple payback. SWA recommends the building to strongly converting away from Propane.
•
Convert Propane unit heaters to infra red heaters – Majority of the building shop already contains propane fired infra red heating tubes. The adjoining Storage garage and the Wash areas were equipped with propane fired unit heaters operated by thermostats, some of which were not even functional. SWA recommends the Township of Raritan to install infra red heating tubes in lieu of the unit heaters. These areas are not usually occupied with people and are not cooled during summer. They are maintained at a low temperature throughout the winter, in order to keep the salt moist and water above freezing. Hence, the savings from the replacement alone would not justify the investment, and this measure should be treated as a capital improvement.
•
Replace exhaust fans – There are about 6 exhaust fans which are either not in operating conditions or are operating beyond their useful service lives. SWA recommends the Township of Raritan to replace these exhaust fans with new, in kind ones. The energy savings alone would be marginal, and the replacement is expected to cost about $3,500.
•
Install premium motors when replacements are required - Select NEMA Premium motors when replacing motors that have reached the end of their useful operating lives.
•
Re-caulk all shifted brick.
Operations and Maintenance Operations and Maintenance measures consist of low/no cost measures that are within the capability of the current building staff to handle. These measures typically require little investment, and they yield a short payback period. These measures may address equipment settings or staff operations that, when addressed will reduce energy consumption or costs. •
Clean and maintain gutters, downspouts and downspout deflectors to minimize uncontrolled roof water run-off causing exterior wall damage.
Steven Winter Associates, Inc. - LGEA Report
Township of Raritan – DPW Building
Page 33/50
•
Maintain weather-stripping around all exterior doors and roof hatches.
•
Provide water-efficient fixtures and controls - Adding controlled on/off timers on all lavatory faucets is a cost-effective way to reduce domestic hot water demand and save water. Building staff can also easily install faucet aerators and/or low-flow fixtures to reduce water consumption. There are many retrofit options, which can be installed now or incorporated as equipment is replaced. Routine maintenance practices that identify and quickly address water leaks are a low-cost way to save water and energy. Retrofitting with more efficient water-consumption fixtures/appliances will reduce energy consumption for water heating, while also decreasing water/sewer bills.
•
SWA recommends that the building considers purchasing the most energy-efficient equipment, including ENERGY STAR® labeled appliances, when equipment is installed or replaced. More information can be found in the “Products” section of the ENERGY STAR® website at: http://www.energystar.gov.
•
Use smart power electric strips - in conjunction with occupancy sensors to power down computer equipment when left unattended for extended periods of time.
•
Create an energy educational program - that teaches how to minimize energy use. The U.S. Department of Energy offers free information for hosting energy efficiency educational programs and plans. For more information please visit: http://www1.eere.energy.gov/education/.
Note: The recommended ECMs and the list above are cost-effective energy efficiency measures and building upgrades that will reduce operating expenses for the Township of Raritan Public Works Department Building based on the requirements of the LGEA program, The Township of Raritan must commit to implementing some of these measures, and must submit paperwork to the Local Government Energy Audit program within one year of this report’s approval to demonstrate that they have spent, net of other NJCEP incentives, at least 25% of the cost of the audit (per building). The minimum amount to be spent, net of other NJCEP incentives, is $1,468.

APPENDIX E: GLOSSARY AND METHOD OF CALCULATIONS Net ECM Cost: The net ECM cost is the cost experienced by the customer, which is typically the total cost (materials + labor) of installing the measure minus any available incentives. Both the total cost and the incentive amounts are expressed in the summary for each ECM. Annual Energy Cost Savings (AECS): This value is determined by the audit firm based on the calculated energy savings (kWh or Therm) of each ECM and the calculated energy costs of the building. Lifetime Energy Cost Savings (LECS): This measure estimates the energy cost savings over the lifetime of the ECM. It can be a simple estimation based on fixed energy costs. If desired, this value can factor in an annual increase in energy costs as long as the source is provided. Simple Payback: This is a simple measure that displays how long the ECM will take to breakeven based on the annual energy and maintenance savings of the measure. ECM Lifetime: This is included with each ECM so that the owner can see how long the ECM will be in place and whether or not it will exceed the simple payback period. Additional guidance for calculating ECM lifetimes can be found below. This value can come from manufacturer’s rated lifetime or warranty, the ASHRAE rated lifetime, or any other valid source. Operating Cost Savings (OCS): This calculation is an annual operating savings for the ECM. It is the difference in the operating, maintenance, and / or equipment replacement costs of the existing case versus the ECM. In the case where an ECM lifetime will be longer than the existing measure (such as LED lighting versus fluorescent) the operating savings will factor in the cost of replacing the units to match the lifetime of the ECM. In this case or in one where one-time repairs are made, the total replacement / repair sum is averaged over the lifetime of the ECM. Return on Investment (ROI): The ROI is expresses the percentage return of the investment based on the lifetime cost savings of the ECM. This value can be included as an annual or lifetime value, or both. Net Present Value (NPV): The NPV calculates the present value of an investment’s future cash flows based on the time value of money, which is accounted for by a discount rate (assumes bond rate of 3.2%). Internal Rate of Return (IRR): The IRR expresses an annual rate that results in a break-even point for the investment. If the owner is currently experiencing a lower return on their capital than the IRR, the project is financially advantageous. This measure also allows the owner to compare ECMs against each other to determine the most appealing choices. Gas Rate and Electric Rate ($/therm and $/kWh): The gas rate and electric rate used in the financial analysis is the total annual energy cost divided by the total annual energy usage for the 12 month billing period studied. The graphs of the monthly gas and electric rates reflect the total monthly energy costs divided by the monthly usage, and display how the average rate fluctuates throughout the year. The average annual rate is the only rate used in energy savings calculations.

* The lifetime operating cost savings are all avoided operating, maintenance, and/or component replacement costs over the lifetime of the ECM. This can be the sum of any annual operating savings, recurring or bulk (i.e. one-time repairs) maintenance savings, or the savings that comes from avoiding equipment replacement needed for the existing measure to meet the lifetime of the ECM (e.g. lighting change outs).
Excel NPV and IRR Calculation In Excel, function =IRR (values) and =NPV (rate, values) are used to quickly calculate the IRR and NPV of a series of annual cash flows. The investment cost will typically be a negative cash flow at year 0 (total cost - incentive) with years 1 through the lifetime receiving a positive cash flow from the annual energy cost savings and annual maintenance savings. The calculations in the example below are for an ECM that saves $850 annually in energy and maintenance costs (over a 10 year lifetime) and takes $5,000 to purchase and install after incentives:

Solar PV ECM Calculation There are several components to the calculation: Costs: Energy Savings: Incentive:
Assumptions:
Material of PV system including panels, mounting and net-metering + Labor Reduction of kWh electric cost for life of panel, 25 years Solar Renewable Energy Credits (SRECs) – Market-rate incentive. Calculations assume $600/Megawatt hour consumed per year for a maximum of 15 years; added to annual energy cost savings for a period of 15 years. (Megawatt hour used is rounded to nearest 1,000 kWh) A Solar Pathfinder device is used to analyze site shading for the building and determine maximum amount of full load operation based on available sunlight. When the Solar Pathfinder device is not implemented, amount of full load operation based on available sunlight is assumed to be 1,180 hours in New Jersey.
Total lifetime PV energy cost savings = kWh produced by panel * [$/kWh cost * 25 years + $600/Megawatt hour /1000 * 15 years] ECM and Equipment Lifetimes Determining a lifetime for equipment and ECM’s can sometimes be difficult. The following table contains a list of lifetimes that the NJCEP uses in its commercial and industrial programs. Other valid sources are also used to determine lifetimes, such as the DOE, ASHRAE, or the manufacturer’s warranty. Lighting is typically the most difficult lifetime to calculate because the fixture, ballast, and bulb can all have different lifetimes. Essentially the ECM analysis will have different operating cost savings (avoided equipment replacement) depending on which lifetime is used. When the bulb lifetime is used (rated burn hours / annual burn hours), the operating cost savings is just reflecting the theoretical cost of replacing the existing case bulb and ballast over the life of the recommended bulb. Dividing by the bulb lifetime will give an annual operating cost savings. When a fixture lifetime is used (e.g. 15 years) the operating cost savings reflects the avoided bulb and ballast replacement cost of the existing case over 15 years minus the projected bulb and ballast replacement cost of the proposed case over 15 years. This will give the difference of the equipment replacement costs between the proposed and existing cases and when divided by 15 years will give the annual operating cost savings.
