Taking a typical residential building of Urumqi as the research object, it uses the Sketch Up software to build the building model. Indoor air temperature and radiation temperature in different ventilation mode on typical date was simulated by the Energy Plus. Indicating that full use of night venti- lation can reduce the indoor temperature to varying degrees. Among them, the top floor room has the best ventilation at night, compared with no ventilation mode, the daytime indoor air temperature decreased by about 3.8℃, the radiation temperature is reduced by about 3...
