A map and table reference of BC Climate Zones per BCBC. The BC Building Code defines the energy performance targets of the Step Code based on the building's climate zone (CZ). The BC climate zones are defined by the average heating degree-days below 18°C (HDD). The BC Building Code states that the authority having jurisdiction (AHJ) can establish climatic values to define climate zones, typically based on information from Environment Canada, and building designers must consult the AHJ before making any assumptions about a building's climate zone. Note that in some locations, there may be several climate zones due to variations in elevation.
