Zero Energy Performance Index (zEPI) Pilot ACP
The Zero Energy Performance Index (zEPI) Pilot Alternative Compliance Path (ACP) was developed specifically for the Canadian market. It provides a new approach to how energy performance is evaluated, adding flexibility, aligning with local energy codes, and better ensuring LEED buildings contribute meaningfully to Canada’s climate goals.
Applicable to LEED v4 and v4.1 projects, the ACP enables projects to use any version of NECB or ASHRAE 90.1 cited by the local authority, avoiding the need to perform additional energy modelling under a different standard or version. More importantly, the pilot ACP uses energy consumption and greenhouse gas (GHG) emissions savings rather than energy cost and GHG emissions savings, thus avoiding distortions that can be caused by differences in fuel costs. The ACP leverages the zEPI calculation methodology.
Taken together, energy consumption and GHG metrics help incentivize efficient, low-carbon designs and align LEED with Canadian market conditions and requirements.
