摘　　要：为了控制建筑能耗排放,提升建筑节能水平,提出离散仿真下建筑钢结构代谢碳排放计量模型设计方法。确定有关碳排放的相关气体,界定建筑物设计、物化、使用和报废四个边界阶段,从各独立边界角度分析与建筑钢结构相关的能耗问题和碳排放量。对钢结构碳排放代谢周期实行离散式分析,分别对钢材生产阶段、运输施工、废弃拆除以及回收再利用等各离散阶段产生的碳排放构建计量模型。经过实验分析,证明所研究模型可在各个离散阶段对建筑钢结构产生的碳排放量实施计量,精确得出不同离散阶段的具体排放量。In order to control building energy consumption and improve energy efficiency,this article presented a method of designing a carbon emission measurement model of building steel structures based on discrete simulation.The relevant gas related to carbon emission was determined at first.And then,four boundary stages,including building design,materialization,use and scrapping,were defined.Moreover,the energy consumption and carbon emission related to building steel structure were analyzed from the perspective of each independent boundary.Furthermore,the cycle of carbon emission of steel structure was analyzed discretely.Respectively,four measurement models of carbon emission were constructed for different discrete stages,including steel production stage,transportation construction,demolition and recycling.Through the analysis of experiments,it is proved that the model can measure the carbon emission of building steel structures in all discrete stages and obtain the specific emission accurately.
