摘　　要：近年来,节能降碳是国家推行的重点工作,特别是在国家制定“双碳”目标后,对降低建筑领域碳排放量的重视程度不断提高。装配式建筑具有绿色环保、施工效率高的特点,一直被国家相关部门大力推广。通过建立传统现浇建造模式和装配式建造模式的碳排放计算模型,锁定边界范围在物化阶段,结合实际项目案例,计算两种建造模式物化阶段碳排放量,对比计算结果并分析不同阶段碳排放量差异的影响因素。结果表明,设计参数完全一致的两栋住宅楼,现浇建筑要比装配式建筑在物化阶段的碳排放量增加7.14 kg/m2。结果为装配式建造模式量化降碳效果提供了有力证明。Energy conservation and carbon reduction is the national focus in recent years.The importance of reducing carbon emissions in the construction sector has been increasing following the“Dual-Carbon Goals”(realizing carbon peak before 2030 and carbon neutrality before 2060)in China.The green and efficient construction of prefabricated building buildings has been vigorously promoted by government.The carbon emission calculation models of traditional cast-in-place construction and prefabricated construction mode are established,and the boundary is locked in the physicochemical stage.Combined with the actual project,the carbon emissions of the two construction models in the materialization stage are calculated,and the influencing factors of carbon emissions in different stages are analyzed.The results show that the carbon emission of the cast-in-place buildings is 7.14 kg/m 2 higher than that of the prefabricated building with the same design parameters,providing strong evidence for quantifying the carbon reduction effect of prefabricated construction model.
