摘　　要：使用清华大学开发的建筑能耗模拟软件DeST-h,对宁波地区一幢典型居住建筑的能耗随东、南、西向窗户遮阳系数的变化规律进行了模拟分析,分析表明:南向窗户遮阳系数对建筑能耗的影响最大,东向次之,西向最小。因此,从减少全年能耗角度考虑,应优先降低南向及东向外窗遮阳系数,其次才是西向。这对夏热冬冷地区的建筑设计具有一定的指导作用。To use Designer＇s Simulation Toolkit （DeST-h） developed by Tsinghua University, the building energy consumption of a typical residential building was analyzed according to shading coefficient of external windows in east, south and west directions of Ningbo, Jiangsu province. The result shows that shading coefficient of external windows in south has big effects on building energy consumption, less than which in east, and least in west. Therefore, shading coefficient of external.windows in south and east was decreased first, and in west secondly. It plays guiding role in building design of hot summer and cold winter zone.
