摘　　要：近年来,超低能耗建筑和近零能耗建筑获得了越来越多的关注。随着国家由增量转存量的建筑节能目标转变,针对住宅建筑的节能改造呈现出巨大的潜力。以寒冷地区典型住宅建筑为案例,进行超低能耗节能改造设计及碳排放测算对比研究。设置30组外墙保温方案、30组屋面保温方案、4组外窗类型方案进行模拟,并基于模拟结果采用敏感性分析进行方案比选。相较基准建筑和改造前建筑,综合最优方案的节能率分别为57.1%、72.1%。采用碳排放因子法对改造前建筑及58组模拟方案进行碳排放测算,可知改造后建筑运行阶段的碳排放量可降低84.2%,并基于测算结果对改造设计方案进一步优化,为既有住宅的超低能耗节能改造提供理论与实践参考。In recent years,buildings oriented for ultra-low-energy and near-zero-energy targets have received increasing attentions.With the energy-saving targets shifting to the existing building stock,the energy-saving retrofit has shown great potential.Taking a typical residential building in cold region as the case study,the energy-saving retrofitting design oriented for ultra-low energy consumption along with the carbon emission calculation were conducted.30 groups of exterior wall insulation schemes,30 groups of roof insulation schemes and 4 groups of exterior window schemes were simulated,as well as the sensitivity analysis for selecting the optimized transformation design scheme.When compared with the benchmark building and the building before retrofit,the energy-saving rates were 57.1%and 72.1%respectively.The carbon emission factor method was adopted to measure the carbon emissions of the building before retrofit and 58 groups of simulation schemes.Based on the results,it can be concluded that,while comparing with the optimized scheme,the carbon emission of the building before retrofit can be reduced by 84.2%,and the design scheme can be further optimized,so as to provide theoretical and practical references for the energy-saving transformation oriented for ultra-low energy residential buildings in cold region.
