摘　　要：超低能耗建筑围护结构通常具备较高的热性能要求,目前已有较多关于不同构造墙体的传热系数研究案例,但针对相同墙体传热系数下对不同墙体构造全寿命期碳排放水平及经济性的研究成果较少。本文针对严寒和寒冷地区常见的7种外墙外保温及夹心保温构造做法,计算其全寿命期下碳排放总量,给出了全寿命期中碳排放最低、经济性最优的墙体构造形式,为超低能耗建筑围护结构设计建造决策提供数据参考,为双碳背景下超低能耗建筑的技术推广提供支撑。The envelop of ultra low energy consumption buildings usually have high thermal insulation performance.There have been many studies on the heat transfer coefficient of different exterior wall structures,but few studies focus on the carbon emission level and economy of different wall structures in the whole life under the same heat transfer coefficient.This paper analyzes seven common methods of wall external insulation and sandwich insulation structures commonly used in severe cold and cold regions,calculates the total carbon emissions in combination with the life-cycle theory,and obtains the wall structure with the lowest carbon emissions and the best economy in the life-cycle,which provides data reference for wall structure decision-making of ultra-low energy building projects,and provides support for the large-scale promotion of ultra-low energy buildings under China's Double-Carbon Policy.

关 键 词：超低能耗建筑 碳排放 全寿命期 传热系数 墙体构造
