LEED v4 and v4.1 ACP Updates

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. This is also the approach of the Zero Carbon Building program.

CaGBC would like to thank its Technical Advisory Group and Steering Committee volunteers for their assistance in developing this ACP.

 

BC Energy Step Code ACP

The BC Energy Step Code ACP provides a recognition path for projects going beyond code, enabling them to earn LEED points for energy performance by simply demonstrating compliance with Step 2 or higher of the BC Energy Step Code.

The ACP is available to Part 3 buildings in British Columbia pursuing LEED v4 or LEED v4.1 under BD+C or Multifamily Midrise, in jurisdictions where the BC Energy Step Code has been referenced and its provisions are being enforced.
