Abstract: Climate change is a major contributor to extreme heat events, which have been a threat to the health of building occupants. It has been found that the rates of mortality and morbidity are much higher for urban dwellers during prolonged periods of elevated outdoor temperature. However, only limited studies have been conducted on the current overheating problems in buildings of different Canadian cities. This study considered multiple existing building overheating metrics, and the trend of evolution of indoor thermal conditions has been analyzed through linear regression. To permit analyzing the long-term variation of indoor conditions within typical buildings located in different cities across Canada, a series of building simulations were performed using weather station data over a historical period ranging from 1986 to 2016. Twelve (12) cities across Canada were selected for analysis that was located in different climate zones. This study determined the current overheating conditions under the 31-year historical climate conditions in two (2) building types: schools and offices.
