In this paper, based on the weather condition of typical cities in hot summer and cold winter area, the indoor air temperature calculation model for a multi-storey building was established with the software of DOE-2, and the influence of shading on indoor air temperature in the middle-floor room from June to September was analyzed. The results demonstrated that shading had significant effect when the comfortable temperature was 28℃. Meanwhile,the indoor comfortable hours could be increased by 50% in summer.%本文针对夏热冬冷地区的典型城市气候条件,通过DOE-2软件建立了多层建筑室内温度计算模型,分析了中间楼层房间在6～9月典型朝向外窗遮阳对室内温度的影响.结果表明:外窗遮阳在以28℃为室内舒适温度时产生的降温效果最为显著,并且可使夏季室内舒适温度时数增加50％左右.
