Coming May 1, 2023: BC Building Code Changes

The BC Building Code changes to enable 20% better energy efficiency and provide an opt-in Zero Carbon Step Code (formerly known as the Carbon Pollution Standard) were signed by the Minister of Housing last week and will take effect May 1, 2023.

 

Some highlights include:

 

• The opt-in Zero Carbon Step Code will be available for local governments to reference starting May 1, 2023.
• Read a PDF convenience copy of the BC Building Code changes (for information only).
• The performance approach for Step 3 in Part 9 construction remains the default option. Local governments wishing to enable a prescriptive energy efficiency approach for Step 3 in Part 9 construction must pass a bylaw to enable that approach. This responds to feedback from rural or remote communities who wish to maintain a prescriptive-based option, while also meeting requests from other local governments wishing to retain the performance-based approach.
• Backup heat from wood stoves and decorative gas fireplaces will be excluded from GHG modelling in Part 9 buildings. This responds to feedback from communities that experience frequent power outages.

 

CHBA BC’s submission incorporated member feedback from all locals and provided recommendations to exclude backup emergency heat.

 

CHBA BC will provide additional updates to our members as the effective date gets closer.
