摘　　要：针对现行供暖居住建筑节能设计标准应用于西藏地区存在有供暖能耗指标却没有完整的能耗计算基本参数,即没有围护结构传热系数的朝向修正系数的问题,以拉萨典型气象年气候参数为依据,采用反应系数法对围护结构各部分供暖负荷进行了动态模拟计算,得到了围护结构各朝向修正系数,对南窗传热系数提出了变系数修正方法。The current energy efficiency design standard for heated residential buildings contains the heating energy index but misses corresponding and complete basic parameters for energy calculation for Tibet, i.e. no orientation correction factors defined for calculating the heat transfer coefficient of building envelopes. Based on the typical year weather data of Lhasa, dynamically calculates the heating load for building envelopes using the response coefficient method, finds the orientation correct factors, and proposes a variable factor correction method for south-facing windows.
