Overheating protection is one of the newer additions to Section 9.33, and builders who assume it requires whole-home cooling often overlook a compliant, lower-cost path: the refuge room approach. This course gives BC home builders practical working knowledge of heating and air-conditioning requirements for a single dwelling unit, what the 26°C overheating threshold means in practice, and how a refuge room can satisfy compliance without whole-home cooling — plus when CSA F280 applies to central mechanical cooling.
You'll also cover duct material and installation requirements where ductwork is part of the system, and how to translate design decisions into permit-ready documentation, including what must be updated if the mechanical design changes mid-construction.
At the end of this course, participants will be able to:
- Apply Section 9.33 requirements for heating and air-conditioning systems in a single dwelling unit, including the overheating protection requirement
- Distinguish between whole-home central cooling and a compliant refuge room approach to overheating protection
- Apply CSA F280 requirements where central mechanical cooling is used
- Meet duct material and installation requirements for systems that include ductwork
- Prepare permit-ready mechanical documentation and update it correctly when the design changes during construction
