摘要:对夏热冬暖地区某居住建筑的生命周期碳排放量进行计算,并分析建筑生命周期内碳排放指标的特征。对建筑生命周期碳排放量各阶段占比和碳排放指标进行分析,结果表明:建筑运营阶段碳排放占居住建筑生命周期碳排放总量的比重最大,其次是建材生产阶段;加强运营阶段碳排放的管理监督,以及增加建筑使用年限是降低建筑碳排放的有效途径。关键词:夏热冬暖;居住建筑;碳排放;生命周期;节能减排Abstract:This paper calculates the life cycle carbon emissions of a residential building in hot summer and warm winter area,and analyzes the building life cycle impact on carbon emissions targets. The results show that the operation carbon emissions accounted for residential building life cycle carbon emission the largest proportion,followed by the building materials production stage. Therefore,strengthening the management on carbon emissions of residential building in the running phase and appropriately increasing the useful life of the building is an effective way to reduce carbon emissions in the building sector.Keywords:hot summer and warm winter zone;residential building;carbon emissions;life cycle;energy conservation参考文献[1] 张智慧,尚春静,钱坤.建筑生命周期碳排放评价[J].建筑经济,2012(2):44-46.[2] 蔡向荣,王敏权,傅柏权.住宅建筑的碳排放量分析与节能减排措施[J].防灾减灾工程学报,2010,30(9)增刊:428-431.[3] 张春霞,章蓓蓓,黄有亮,等.建筑物能源碳排放因子选择方法研究[J].建筑经济,2010(10):106-109.建筑经济,2014(9):75-80
