The BC Building and Safety Standards Branch has created the following BC Step Code changes for Part 9 homes (single detached, townhomes, etc.) taking effect May 1, 2023:
- Introduces the Zero Carbon Step Code, an opt-in building carbon pollution standard for operational carbon
- Introduces a prescriptive option for Step 3, Part 9 buildings if a local government passes an enabling bylaw
- More airtightness testing options
- New energy performance improvement compliance calculations
The changes apply to building permits applied for on or after May 1, 2023.
We have asked for clear interpretations of the changes, especially the Zero Carbon Step Code, however the branch reports they have nothing available at this time. When available, we will forward the information to VRBA members. For more information, visit https://energystepcode.ca/requirements/#bcbc-2018-rev-4
