Overview The Canada Green Building Council (CaGBC) has embarked upon a multi-year development project to introduce the next generation of LEED in Canada through the LEED Canada Initiative. In parallel to this effort, the CaGBC also launched GREEN UP - Canada's Building Performance Program (formerly called Green Building Performance Initiative) a focused effort to develop an affordable and easily accessible tool for energy and environmental management for new and existing buildings. Both initiatives will enable large-scale reduction in greenhouse gas emissions, energy savings, and other environmental benefits for all building types and communities across Canada.

What is LEED? •

The Leadership in Energy and Environmental Design (LEED) Green Building Rating System™ encourages and accelerates global adoption of sustainable green building and development practices through the creation and implementation of universally understood and accepted tools and performance criteria.



LEED is a third-party certification program and an internationally accepted benchmark for the design, construction and operation of high performance green buildings. It provides building owners and operators the tools they need to have an immediate and measurable impact on their buildings’ performance.



LEED is a point-based rating system; points are earned for building attributes considered environmentally beneficial. LEED differs from other rating systems in that it has quantified most of the "green credits."



Goal is to reduce the carbon footprint

What is LEED? LEED promotes a whole-building approach to sustainability by recognizing performance in five key areas of human and environmental health: 1. sustainable site development 2. water efficiency 3. energy efficiency 4. materials selection 5. indoor environmental quality Credits and Prerequisites are organized into these five categories.

An additional category, Innovation & Design Process, addresses sustainable building expertise as well as design measures not covered under these five environmental categories.

LEED Certification Certification is based on the total point score achieved, following an independent review and an audit of selected Credits. Four possible levels of certification ($): 1. Certified 2. Silver 3. Gold 4. Platinum The Canadian rating systems are an adaptation of the US Green Building Council's (USGBC) LEED Green Building Rating System, tailored specifically for Canadian climates, construction practices and regulations.

Why Certify? A rapidly-growing number of private sector organizations and governments are adopting LEED certification in their policies, programming and operations, with the goal of achieving and demonstrating sustainability. The reasons for certifying include: 1. Gain recognition for green building efforts ($) 2. Validate achievement through third party review ($) 3. Qualify for a growing array of government incentives ($) 4. Contribute to a growing green building knowledge base

LEED Canada Green Building Rating Systems There are a number of LEED Canada rating systems available to meet the needs of different building and project types. These include: 1. New Construction 2. Commercial Interiors 3. Core & Shell 4. Existing Buildings – Operations & Maintenance 5. Homes 6. Neighbourhood Developments

1. New Construction (NC) The LEED Canada-NC 1.0 rating system applies to new construction and major renovations of commercial and institutional buildings, i.e., buildings regulated by Part 3 of the National Building Code. It also applies to retail, mid- and high-rise multi-unit residential buildings (MURBs), public assembly buildings, manufacturing plants, and other types of buildings. The thresholds for LEED Canada-NC 1.0 are: • Total available: 70 points • • • •

Certified: Silver: Gold: Platinum:

26 points 33 points 39 points 52 points

2. Commercial Interiors (CI) LEED Canada for Commercial Interiors is the green benchmark for the tenant improvement market. It is the recognized system for certifying high-performance green interiors that are healthy, productive places to work; are less costly to operate and maintain; and have a reduced environmental footprint. LEED Canada CI gives the power to make sustainable choices to tenants and designers, who do not always have control over whole building operations. The thresholds for LEED Canada CI 1.0 are: • Total available: 57 points • • • •

Certified: Silver: Gold: Platinum:

21 points 27 points 32 points 42 points

3. Core and Shell (CS) LEED Canada for Core and Shell (CS) is a derivative of LEED Canada NC and applies to buildings where less than 50% of the building area will be fit-up to LEED Canada NC requirements prior to certification. The thresholds for LEED Canada CS are: • Total available: 70 points • • • •

Certified: Silver: Gold: Platinum:

26 points 33 points 39 points 52 points

4. Existing Building – Operation & Maintenance (EB: O&M 2009) LEED® Canada for Existing Buildings: Operations and Maintenance represents an ongoing commitment by building operators to continuously assess the environmental performance their buildings. The LEED Canada EB:O&M 2009 rating system helps building owners and operators measure operations, improvements and maintenance on a consistent scale, with the goal of maximizing operational efficiency while minimizing environmental impacts. LEED Canada EB:O&M 2009 addresses whole-building cleaning and maintenance issues (including chemical use), recycling programs, exterior maintenance programs, and systems upgrades. Buildings may be operated and maintained for decades, and so under this rating system they must file for recertification at least once every five years to maintain their LEED Canada EB:O&M status. The thresholds for LEED Canada EB: O&M 2009 are: • Total available: 110 points • • • •

Certified: Silver: Gold: Platinum:

40 points 50 points 60 points 80 points

5. Homes • LEED Canada for Homes is a rating system that promotes the design and construction of highperformance green homes. A green home uses less energy, water and natural resources; creates less waste; and is healthier and more comfortable for the occupants. • Benefits of a LEED home include lower energy and water bills; reduced greenhouse gas emissions; and less exposure to mold, mildew and other indoor toxins. The net cost of owning a LEED home is comparable to that of owning a conventional home.

6. Neighbourhood Developments (ND) •

The USGBC has developed a draft of the LEED for Neighbourhood Development (LEED ND) rating system to guide and assess sustainable community development. The system was created as a partnership between the USGBC, Natural Resources Defense Council and the Congress of New Urbanism. The USGBC is moving into a pilot project phase to test the draft standard with actual community development projects before finalizing and releasing LEED ND in the US.



The CaGBC has been approached by industry leaders and local governments across the country to introduce LEED ND in Canada as soon as possible. The CaGBC hopes to introduce LEED Canada ND in 2010. A number of Canadian projects are taking part in the USGBC LEED ND pilot and will inform the adaptation of the rating system in Canada.

Certification LEED Certification distinguishes building projects that have demonstrated a commitment to sustainability by meeting the highest performance standards. The Certification process involves: • Documentation • Credit Interpretations • Certification It is helpful to have a LEED Accredited Professional as the project contact and team member responsible for coordinating the LEED process. (Note: you get 1 point for using a LEED Accredited Professional)

LEED Accredited contractors – makes your life easier. Need to make the decision to go LEED as 1st step in the project. Critical to start the documentation immediately and follow through in detail throughout the entire project. Ex: raw material, proximity,
