外窗遮蔽系数是影响住宅建筑能耗的重要因素之一。针对重庆地区的高层住宅建筑,利用美国加州大学劳伦斯贝克利实验室(Lawrence Berkeley National Laboratory)开发的Doe-2建筑能耗动态模拟分析软件,计算不同朝向的外窗、在不同窗墙比条件下,外窗遮蔽系数对住宅建筑能耗的影响规律,得出各朝向窗对遮蔽系数的要求。 Outer window shadowing coefficient is one of the important factors that affect the energy consumption of residential buildings. According to the Doe-2 building dynamic simulation software developed by Lawrence Berkeley National Laboratory of the University of California at the high-rise residential building in Chongqing, windows with different orientations are calculated. Under different window-wall ratio conditions , The effect of shadowing coefficient of exterior window on the energy consumption of residential buildings, and obtained the requirements of the sheltering coefficient of each orientation window.
