Creating Sustainability in Our Schools
Why CEEMI? (Global) • Manage Limited Resources and Budgets • Act Socially Responsible • Teach Environmental Stewardship to Our School District and Community ….We all prac9ce this to varying degrees Comprehensive Energy and Environmental Management Initiative
Creating Sustainability in Our Schools
CEEMI Strategies: 1. Behavioral Modifica9ons 2. Building System Op9miza9on 3. Environmental Strategies 4. Energy Strategies 5. Capital Improvements 6. Building Cer9fica9on 7. Educa9onal Integra9on
Comprehensive Energy and Environmental Management Initiative
Strategy #1: Behavioral Modi,ications Real Savings… § Restrict Thermostat Setpoint Range on Trane Tracer System: • heat no higher than 71 degrees • cool no lower than 73 degrees
§ Modified Cutler Hammer Ligh9ng Control Schedule: • manual on switch in mornings • classroom sweeps at evening intervals
…Reduc%on in kwh/therms up to 10%
Strategy #1: Behavioral Modi,ications Best Practices in Food Service Real Savings… § Water § Electric instantaneous heaters § Aerators on hand wash sinks § Electricity/Gas § “Just In Time” Opera9ons (ovens, hot wells, warming cabinets) § HVAC § Close F/C doors during deliveries § Vacuum coils on condenser units § Add frequency drives on AHU’s
Strategy #1: Behavioral Modi,ications Reduce Printing Waste
Real Savings… §
73,214,882 Copies Made in ‘08/’09
§
Established Copy Limits in ‘09/’10
§
Goal: 20% Volume Reduc9on (14,500,000)
§ Actual Reduc9on: 19,000,000 …$190,000 Savings in One Year!
Strategy #2: Building System Optimization Rezone Building Temperature Controls
Real Savings…
Temperature Controls at Wood View ES: 1. 2.
3.
4.
Rezone building to separate interior and exterior spaces Wrote program to monitor average and extreme temperatures at perimeter Wrote program to allow override control of outside air dampers Wrote program to allow override of classroom cooling dampers
Fan energy dropped by nearly 70%, represen9ng $250 per week savings, per school!
Strategy #2: Building System Optimization Pumps, Fans and Variable Frequency Drives
Real Savings…
From Summer of 2007 through today: § Over 30 Variable Frequency Drives installed on AHU’s, RTU’s, Fans, Chiller/ Boiler Pumps § 2 “Fan Walls” installed for AHU’s § Mul9ple new efficient Chiller/Boiler Pumps
§ Used in house labor for all installa9ons
Strategy #2: Building System Optimization Utilize Technology
Building Automation System (BAS): § Utilize Trane Tracer Software as Platform § Migrating to Trane’s ES Web Based System § Allows Universal Monitoring and Response
to Temperature Control in the District § Future Goal is to Incorporate ‘Dashboard’
Capability
Strategy #3: Environmental Strategies Recycling Pick-‐ups at Schools
Real Savings… § Re-‐evaluated recycling dumpster pick-‐up at schools § Went from 2 pick-‐ups/week with 6 yard dumpster to 1 pick-‐up/week with an 8 yard dumpster
Annual savings of $3,900 for our elementary schools
Strategy #3: Environmental Strategies Recycling Pilot Program: Plastics, Metal & Paper
Identify and Educate Staff/Students of Opportunity Goal for Each Cafeteria and Kitchen: from 7 bags of trash daily to 5 bags of trash and 2 bags of recycling daily 2 bags diverted daily X 100 school days (175 days/school year) X 12 elementary schools 2,400 bags diverted from landfill each year!
Strategy #3: Environmental Strategies Recycling Program: Scrap Material
Initiated by Grounds Department… • Collect scrap material from district projects • Normally would end up in landfill • Transport material to recycling yards
…Collect approx. $25,000 annually in scrap payments.
Strategy #3: Environmental Strategies Recycling Pilot Program: Styrofoam Styrofoam (polystyrene) Recycling: § Over 1 million Styrofoam Lunch
Trays Used Annually § Establish Lunch Room Program in
Each School to Clean and Stack Trays § Transport Bagged Trays to Recycling
Center § Goal is to further reduce trash
quantity and increase recycling amount
…Over 20,000 trays a week diverted from landfill.
Strategy #3: Environmental Strategies Bio Soils on Grounds Work
Real Savings… § Jane Addams Site Improvement Project § Obtained Soils Free of Charge from Metropolitan Water Reclamation District § Used as Amendment to Topsoil § Improves Soil Quality § Adds Organics § No Weeds § Reduces Long Term Soil Maintenance
…saved $12,000 on new soccer field (40 semi-‐loads @ $300/load)
Strategy #3: Environmental Strategies Green Cleaning Program § All Schools Comply with Illinois Green
Cleaning Act § District Initiative is to EXCEED Standards-
built into our cleaning specifications • Additional green cleaning products
(hand soap, green seal certified products) • Microfiber dust pads and clothes in
lieu of terry cloth and paper towels • Use of water based scrubbers (no
chemicals)
Strategy #4: Energy Strategies Condensate Recovery System
Real Savings (Bolingbrook High School) Condensa9on from main AHU’s collected in a tank and used as make-‐up water for cooling towers. • Es%mated to save 257,000 gallons of water/year. • Approximately 7% of total water used for cooling system.
Strategy #4: Energy Strategies Energy Grants

Fixtures in Fieldhouses and Gyms § L.E.D. fixtures more energy efficient than Metal Halide § Installation Summer 2014 § Benefits: • Complete light level flexibility • Reduced maintenance costs • Reduction in electrical usage • Estimate $51,700 annual savings
Strategy #6: Building Certi,ication LEED Certi,ication
Real Savings…
Our “green” school performs posi9vely… but room for improvement, currently 58.5 Energy Use Intensity (EUI)!
Strategy #6: Building Certi,ication Governor’s Illinois Sustainable Schools Compact
Commitment of Individual Schools to Sustainable Practices: § Conserve Energy and Lower Carbon Emissions § Encourage Recycling and Purchase Products
with Minimal Packaging § Conserve Water for Landscaping § Plant Drought Resistant Native Species in Landscaping Areas
Strategy #7: Educational Integration Showcase School Programs
The Ecology Club at Mar9nez Middle School… § Students Interested in Environmental Issues § Students Sponsor Various Projects § Recycled Art Fair § Earth Day Celebra9on
