The global standard in green building
Leadership in Energy and Environmental Design or LEED® is an international symbol of sustainability excellence and green building leadership. LEED’s proven and holistic approach helps virtually all building types lower carbon emissions, conserve resources, and reduce operating costs by prioritizing sustainable practices. Canada is one of the top territories in the world for LEED certification.
Buildings generate nearly 30% of all greenhouse gases, and 35% of landfill waste, while consuming up to 70% of municipal water.

Why LEED
LEED works because it recognizes that sustainability is key to the design, construction, and operation of all buildings. LEED helps owners and developers create high-performing, resilient buildings that reduce carbon emissions, save water, conserve energy and reduce waste. LEED also improves people’s quality of life by delivering the optimal conditions for health, comfort and productivity – such as better quality air and natural light.
LEED certification provides independent, third-party verification that a building project was designed and built, or operated, to achieve high performance in six areas of human and environmental health:

Location & Transportation

Sustainable Site Development

Water Savings

Energy Efficiency

Materials Selection

Indoor Environmental Quality
How LEED works
Projects pursuing LEED certification earn points for green building strategies across several categories. Based on the number of points achieved, a project earns one of four LEED rating levels: Certified, Silver, Gold or Platinum.
LEED certification involves a few steps.
- Determine which LEED rating system you are eligible for.
- Register your project at LEED Online and pay the registration fee to demonstrate your commitment.
- Prepare and submit your certification application for review by CAGBC along with a certification fee.
- After a detailed review, projects receive the decision. Successful candidates are certified.
Find the LEED that’s right for you
LEED is for all building types and all building phases including new construction, interior fit outs, operations and maintenance and core and shell.
Building Design and Construction (BD+C)
For new construction or major renovations, including Core & Shell projects.
Interior Design and Construction (ID+C)
For complete interior fit-out projects.
Operations and Maintenance (O+M)
For existing buildings that are not undertaking a major renovation.
Recertification
For projects that have previously achieved certification under LEED — including BD+C and ID+C.
Homes
For single family homes, low-rise multi-family (1 to 3 storeys ) or mid-rise multi-family (4 to 6 storeys).
Cities and Communities
For entire or sub-sections of a city, to measure and manage water consumption, energy use, waste, transportation and human experience.
Neighborhood Development (ND)
For new land development or redevelopment projects for residential, non residential or mixed usages.
CAGBC’s role in LEED
LEED leans on the green building community to continuously improve and stay ahead of evolving government policy. CAGBC represents Canada in LEED’s international development process, and supports the market with certification, verification, education and training. CAGBC members play a vital role in this work, supporting the LEED Canada Steering Committee and Technical Advisory Groups.
LEED Interpretations
Administered by the USGBC, LEED Interpretations are published periodically in the form of official addenda. LEED Interpretations provide answers to technical inquiries about applying LEED in situations not already addressed by the rating systems, reference guides and Minimum Program Requirements. Teams can access published LEED Interpretations online in the searchable addenda database.
Alternative Compliance Paths (ACPs) and Resources
ACPs provide project teams the flexibility to use locally-relevant, equivalent means of demonstrating compliance to credit requirements. Read up on ACPs applicable in Canada:
LEED v4 Canadian Alternative Compliance Paths (ACPs) – outlines ACPs available to Canadian LEED v4 projects
Zero Energy Performance Index (zEPI) Pilot ACP – enables LEED v4 and LEED v4.1 projects to use any version of NECB or ASHRAE 90.1. Uses energy consumption and greenhouse gas emissions savings, and the zEPI calculation methodology.
