摘　　要：为顺应建筑业低碳、节能、环保的可持续发展策略,基于PKPM-CES软件对福建某地区同一住宅小区中的装配式建筑与现浇砼建筑进行全寿命周期碳排放当量对比分析,涵盖建材生产、建材运输、建筑建造、建筑运行、建筑拆除到绿植碳汇减排6个阶段。结果显示,装配式建筑单位面积碳排放当量较现浇砼建筑少354.56kgCOze。装配式建筑与现浇砼建筑主要碳排放当量均集中在建筑运行阶段,分别占其全寿命周期碳排放当量的79.09%、84.53%;其次为建材生产阶段,分别占17.37%、12.77%。因此,装配式建筑与现浇砼建筑应重点关注建筑运行与建材生产阶段的标准化技术革新。To align with the sustainable development strategy of low-carbon,energy-saving and environmental-friendly in the construction industry,a life-cycle carbon emission equivalence(CO_(2)e)analysis was carried out using PKPM-CES software for prefabricated buildings and cast-in-place concrete buildings within the same residential community in Fujian Province.The analysis covered six stages:building material production,building material transportation,building construction,building operation,building demolition and carbon sink from green plants.The results indicated that prefabricated buildings emitted 354.56 kgCO_(2)e less per unit area compared to cast-in-place concrete buildings.For both types of buildings,the major part of carbon emissions occurred in the building operation stage,accounting for 79.09%(prefabricated)and 84.53%(cast-in-place)of their total life-cycle emissions respectively.The building material production stage was the second-largest emitter,contributing 17.37%and 12.77%respectively.Therefore,prefabricated buildings and cast-in-place concrete buildings should focus on the standardized technological innovation in the building operation and building material production stages.
