中文摘要：

以乌鲁木齐市某典型住宅建筑为研究对象,采用Sketch Up建立建筑模型,并用Energy Plus模拟计算在不同通风模式下典型日的室内空气温度和辐射温度。表明充分利用夜间通风,可不同程度降低房间温度。其中,顶层房间夜间通风效果最好,较无通风模式日间室内空气温度约降低3.8℃,辐射温度约降低3.8℃,改善室内热环境效果显著。

英文摘要：

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 3.8℃, the indoor thermal envi- ronment improve effect is remarkable.
