摘　　要：乡村住宅低碳化设计已成为主要趋势,外围护结构材料选择是实现低碳化设计的关键一环。本研究采用碳排放系数法测算交叉层压木(CLT)代替砖砌体作为寒地乡村住宅外围护材料在全生命周期的碳排放。结果表明,在严寒地区使用CLT的乡村住宅的全生命周期总碳排放量为682029.34kg CO_(2)e,远低于使用砖砌体的703212.43kg CO_(2)e,CLT代替砖砌体在全生命周期的节碳率为3.01%;在运行阶段的减碳量最高,达13188.74kg CO_(2)e。研究揭示了CLT在严寒地区乡村住宅的减碳潜力,为实际工程提供参考。Low-carbon design for rural housing has become a major trend,and the selection of envelope structure materials is a key component in achieving low-carbon design.The study used the carbon emission coefficient method to calculate the carbon emissions over the life cycle when cross-laminated timber(CLT)is used instead of brick masonry as the envelope material for rural housing in cold regions.The results show that the total life cycle carbon emissions of rural housing using CLT in extremely cold regions amount to 682,029.34 kgCO_(2)e,which is significantly lower than the 703,212.43 kgCO_(2)e of brick masonry,with a carbon reduction rate of 3.01%over the life cycle by replacing brick with CLT.The highest carbon reduction occurs during the operational phase,reaching 13,188.74 kgCO_(2)e.The study reveals the carbon reduction potential of CLT in rural housing in cold regions,providing a reference for practical applications.
