Revision 5, related to the Zero Carbon Step Code, has been published.
Effective March 10, 2025, new buildings must meet at least EL-1 of the Zero Carbon Step Code. This means that applicable buildings will be required to measure and disclose operational greenhouse gas emissions.
The Part 3 and Part 9 Step Code Compliance Checklists already disclose operational greenhouse gas emissions to the Authority Having Jurisdiction, so users of those checklists are already familiar with GHG reporting.
Local governments retain the ability to require or incentivize compliance with higher levels of the Zero Carbon Step Code.
You can access Revision 5 of the BC Building Code 2024 on the Errata & Revisions page of the Building Codes and Standards website.
