Influence of Urban Heat Island on Office Building Energy Consumption

In order to investigate the influence of urban heat island on office building energy consumption which is located on different land use types, several representative land use types were selected in Chongqing to do continuous air temperature measurements on August 2007 and January 2008. Urban heat island intensities were obtained with the measured data. The energy consumption simulation software eQUSET was employed to simulate the influence of urban heat island on cooling loads and heating loads of office building separately. The results showed that commercial areas usually have high urban heat island intensities. Additionally, the energy consumption of air conditioning in office building would be increased by 3.48kWh/m² and the energy consumption of heating would be decreased by 1.22kWh/m² when the UHI intensity increased by 1°C.
