Efforts by CaGBC and industry stakeholders shift focus to energy consumption and carbon emissions
Ottawa, ON – December 14, 2020 – The unique needs of the Canadian market were reflected in the latest addenda to the Leadership in Energy and Environmental Design (LEED) rating system. They include an alternative compliance pathway (ACP) that shifts the focus from energy cost to energy usage.
The LEED v4 and LEED v4.1 zEPI Pilot ACP was accepted by the U.S. Green Building Council (USGBC), LEED’s governing body, before being included in the most recent addenda. It follows over a year of effort by the Canada Green Building Council (CaGBC) its Technical Advisory Group (TAG) and Steering Committee volunteers as well as key stakeholders.
“The Canadian building sector operates in an evolving market driven by changing climate change policy and regulation,” said Mark Hutchinson, Vice President of Green Building Programs at CaGBC. “The ACP process enables us to identify and research approaches that evolve LEED for the needs of the Canadian market and deliver on more efficient, climate-resilient buildings.”
As an option, LEED projects can now use reductions in energy consumption and GHG emissions to evaluate energy performance by leveraging the Zero Energy Performance Index (zEPI) calculation methodology.
With this new ACP, projects can use any version of the National Energy Code of Canada for Buildings (NECB) or ASHRAE 90.1 cited by the local authority and avoid the need to perform additional energy modelling under a different standard or version.
By shifting focus to energy consumption rather than energy cost, projects can avoid distortions caused by differences in fuel costs. Taken together, energy consumption and GHG metrics will help incentivize efficient, low-carbon designs and align LEED with Canadian market conditions and requirements.
It is anticipated that these addenda, including this ACP, represent the last significant updates to LEED v4.1 BD+C and ID+C before going to ballot, likely in 2021.
CaGBC is the leading national organization dedicated to advancing green building, building retrofit, and sustainable community development practices. As the voice of green building in Canada, CaGBC works with industry and government at the local, provincial, and national levels to make every building greener. CaGBC focuses on reducing carbon emissions and the overall environmental impacts of buildings while improving occupant health and contributing to a vibrant low-carbon economy. To accomplish this, CaGBC sets and verifies advanced green building standards, conducts government advocacy and market research, and provides education and training that has reached over 45,000 Canadian professionals since 2002. In 2004, CaGBC established the LEED® green building rating system in Canada and developed the first Zero Carbon Building Standard in 2017. CaGBC is a member of the World Green Building Council, supporting international efforts to reduce environmental impacts and enhance global health in buildings and communities.
