With rapid urbanization, urban areas become much warmer than rural areas, which is generally known as the urban heat island (UHI) effect. As hourly weather data are commonly available at weather stations located in remote and rural areas, the UHI effect is usually underestimated, and even neglected for modeling building energy, which leads to the underestimation of urban building energy use. In this study, we examined the impact of UHI on the urban building energy spatially and temporally. Firstly, a UHI effect considered hourly weather data was developed for the study area. Secondly, building energy consumption has been simulated by using the urban building energy use model, and the newly developed UHI effect considered weather data. Finally, the impact of UHI effect on building energy use was investigated spatially and temporally.
