摘　　要：采用建筑能耗模拟软件 DeST-h,对宁波地区某典型居住建筑各朝向外窗传热系数对建筑能耗的影响进行了模拟分析。降低各朝向外窗传热系数均可降低供热量,但供冷量有小幅提高。南向外窗传热系数对建筑能耗的影响最大,北向次之,东、西向最小。The influence of heat transfer coefficient of external windows facing different directions of a typical residential building in Ningbo region on building energy consumption is analyzed by building energy consumption simulation software DeST-h. The decrease of heat transfer coefficient of external windows facing different directions can reduce heat-supply quantity, but increase slightly cooling supply quantity. The influence of heat transfer coefficient of external windows facing south on building energy consumption is the greatest, followed by those facing north, east and west.
