Fall Public Review for the 2025 Code Cycle
The current public review for the 2025 code cycle is open and the deadline to submit comments is December 19, 2024. CHBA members are encouraged to help shape future codes by providing comments. The Proposed Change Forms (PCF) are available on the Canadian Board for Harmonized Construction Codes (CBHCC) website. There are two key proposals that are being resubmitted because substantive comments in earlier public reviews – including many from CHBA – have led to significant revisions:
- PCF 1823 now provides more granularity when limiting the maximum solar heat gain coefficient for windows,
- PCF 2026 now aligns the prescriptive requirements for operational greenhouse gas emissions with the point trade-off system for energy efficiency.
There is also a third PCF that will have a major impact on the installation of doors and windows:
- PCF 1950 clarifies the requirements for protection from precipitation of rough opening sills for windows and doors by extending the second plane of protection, in combination with PCF 1951 which allows for reduction of insulation levels to allow for water drainage.
Additionally, there is an ad-hoc public review scheduled for January 2025 to cover the following PCF:
- PCF 2061 which adds a maximum safe indoor air temperature to address overheating in new dwelling units will be extensively revised.
As these proposals will significantly impact the residential construction industry, visit CHBA’s webinar page if you want to learn more about how these PCFs were originally proposed. For more information or if you want CHBA staff to include your comments in our submission, please contact Frank Lohmann, Jack Mantyla or Alex Bols.
