| Abstract | Overheating in buildings has been a major health concern for vulnerable occupants during extreme heatwaves. Even though indoor overheating is highly dependent on outdoor climate, it may also be affected by other factors including building envelope characteristics, HVAC operation and internal heat gains. This study is to investigate the synchronisation of indoor overheating with outdoor heatwave. Archetype residential buildings were created and used to conduct EnergyPlus simulations of 31 years climate data of three major Canadian cities. A heatwave evaluation method developed by National Research Council of Canada was used to define heat events and extreme summer weather years. The method uses the transient standard effective temperature (t-SET) to rank heat events in terms of duration, intensity and severity. The results show that in most building configurations, outdoor extreme heatwaves are synchronised with indoor extreme overheating events. Outdoor-based extreme summer weather years are therefore suitable to study indoor overheating risks. |
