摘要：以某装配式建筑项目工程为例，对装配式建筑物化阶段建立计算评价模型，与现浇建筑进行碳排放分析对比，并针对装配式生产阶段进一步提出碳减排途径，对减排途径进行计算，确定减排效果。结果表明，相比于现浇建筑，装配式建筑在建筑物化阶段可减少碳排放量2.65 kg/m2。

Abstract：Taking a prefabricated project as an example，this paper establishes a calculation and evaluation model of prefabricated building in the physical and chemical stages，and compares the carbon emission reduction between prefabricated buildings and cast-in-place concrete buildings，proposes the ways of carbon emission reduction and calculates them to determine the emission reduction effect. The results show that，compared with cast-in-place buildings，the carbon emissions of prefabricated buildings can be reduced by 2.65 kg/m2 in the physical and chemical stages.
Key words：prefabricated building，carbon emission reduction，computational model，building energy efficiency
