摘　　要：JGJ26—2010《严寒和寒冷地区居住建筑节能设计标准》中提出的外墙平均传热系数简化算法为外墙平均传热系数的计算提供了一个捷径,大幅度地提高了建筑节能设计的工作效率。但此算法只适用于外墙外保温的钢筋混凝土剪力墙结构。同时,对于低层、多层的住宅建筑,采用简化算法所得结果误差较大,不宜简单的应用。In the Standards on Energy Saving Design for Freezing and Cold Area Residential Buildings（JGJ26-2010）,a simplified algorithm of the average thermal transmission coefficient for the building envelope is proposed,which is a shortcut to designer＇s calculation and an improvement for the efficiency of the energy conservation.But the algorithm can be used only in the reinforced concrete shear wall structure with the exterior insulation.Meanwhile,the simplified algorithm will obtain errors for low-rise and multi-storey residential buildings.
