Increasing climate change brings not only global warming, but also more frequent and severe extreme events, which greatly affect the indoor environment. There has been some research discussing the impacts of extreme events on indoor thermal environment, mostly related to heatwaves, but quite limited on extremely cold events which occurred in recent years. In this study, the indoor environment was simulated in a typical residential building in China’s hot summer and cold winter climate zone, that has faced both kinds of events, using ERA5 database (reanalysis weather data) in the past 40 years. The simulation results were analyzed for a better understanding of the indoor events of extreme hot or cold conditions and were used to select the weather data for modelling extreme event impacts, including a typical hot year and typical cold year defined in this study. The impacts of the indicator were used to evaluate overheat or extreme cold conditions, and the building envelope level were also discussed.
