中文摘要：

建筑遮阳系数对建筑能耗和室内热环境均有影响,而室内空气温度作为影响热舒适的主要因素与窗户遮阳存在必然联系。采用DOE-2软件计算方法分析遮阳系数变化时室内温度降低的分布情况,说明夏季设置外遮阳对室内热环境改善的效果。

英文摘要：

Modulus of architecture windows shade can both affect building energy consumption and indoor thermal environment.As the main factor which affects thermal comfort,indoor air temperature should have a necessary connection with windows shade.The DOE-2 software is used to analyze distribution of room temperature decreasing by the change of windows shade,illustrated the improving effect of indoor thermal environment by installing windows shade in summer.
