CSA F280 Heat Loss & Heat Gain Requirements for Part 9 Buildings

Description

2 CPD

CSA F280 is the Canadian standard used to calculate heating and cooling loads for houses and small residential buildings. In practice, it defines how big your furnace, heat pump, and cooling equipment are allowed to be based on an engineering calculation instead of rules‑of‑thumb. In British Columbia, CSA F280 is no longer optional—it is now embedded in the 2024 BC Building Code for residential construction.
