| 摘 要： | 以机组流水法及固定模台法两种预制构件生产工艺过程为研究对象，分别计算预制内墙板构件在生产过程中因材料、电、水、人工消耗产生的碳排放并进行对比分析，结果表明以 2.3m×2.75m×0.2m 尺寸的构件为例，机组流水法与固定模台法的每立方混凝土碳排放量分别是 706.198kg 与 706.378kg 。其中材料消耗产生的碳排放量占 99%以上，采用机组流水法时因电力消耗产生的碳排放占 0.78%，因人工消耗产生的碳排放占 0.02%。采用固定模台法时因电力消耗产生的碳排放占0.74%，因人工消耗产生的碳排放占 0.01%。通过对比分析两种生产方式碳排放组成比例，可以为减少工业化建筑碳排放提供参考。

| Abstract: | This paper analyzes the GHG emissions embodied in the material use，electricity use，water consumption and workers’daily activities in the whole process of component manufacturing. A comparative analysis was conducted to explore the emissiondifference between the flow-line（FL）and the fixed-platform method （FPM），The results show that the GHG emissions of twomethods are 706.198kg and 706.378kg respectively in per cubic meter of concrete. Materials contribute to more than 99% of allGHG emissions，followed by electricity（0.78% in FL and 0.74% in FPM）and workers（0.02% in FL and 0.1% in FPM）. Throughcomparing and analyzing the carbon emissions composition ratio of two methods，this paper can provide reference for reducing thecarbon emissions of industrialized buildings. |
