Alberta Building Code Updated for A2Ls on October 22, 2024
HRAI staff have been working with federal, provincial, and territorial officials for many months to ensure that codes are being updated to enable the HVACR’s transition to A2L refrigerants.
Alberta’s Building Code has been updated, through a Variance to accept the 2023 edition of CSA B52 effective October 22, 2024. This change enables the installation of A2L systems in buildings subject to the Alberta Building Code – including residential dwellings (new construction and renovations) and most other buildings.
To access the Variance, you may click on the following link on Alberta’s Building STANDATA page: https://www.alberta.ca/building-standata, scrolling down to Building code variances (2023) to view the document numbered 23-BCV-009. A direct link is also available by clicking here.
