摘　　要：针对太阳能富集地区居住建筑外墙构造特点和室外综合温度条件,以拉萨地区为例进行研究,提出了采暖居住建筑非平衡保温节能墙体构造,其中南墙不做保温、东西墙和北墙采用外保温。在对当地典型居住建筑形式和围护结构现状调研基础上,采用南墙兼顾延迟时间和传热系数,东西墙、北墙单位面积等净失热量的分析方法,确定了非平衡外墙的传热系数,并对以此设计的非平衡保温构造总净热损失和内表面温度进行了分析。给出了非平衡保温构造的计算与分析方法,为同类地区非平衡保温构造设计提供了方法和理论依据。Study taking energy efficiency residential building in Lassa region as an exapmle, suggests a concept of no-uniformity insulation envelope configuration. In this envelope configuration, south wall without exterior insulation and exterior insulation systems were employed in other exterior walls. Based on the investigation of representative residential building modality and envelope characteristic in Lassa region, thermal transfer coefficient of no-uniformity insulation envelope was calculated acooding to the analyse method that time lag and thermal transfer of south exterior wall are regarded synchronously and unit area net thermal losing is equated each other in other exterior walls. In this paper the whole net ther- mal losing and the surface temperature of no-uniformity insulation envelope were analysed. Therefore, not only the anal- yse method was suggested but also provided better information for design of no-uniformity insulation envelope configuration in same region.
