夏热冬冷地区建筑采暖和制冷的能源消耗正在迅速增加,从而导致碳排放的增加.通过模拟试验,以建筑碳排放和经济成本为效果导向.基于苏州的既有住宅,选取了外墙保温层厚度、窗户类型和气密性作为研究变量,设置正交试验,采用软件模拟计算得出每种优化策略的碳排放和建筑的生命周期成本.结果表明:从减少碳排放的角度出发,与样本建筑相比,最优方案的碳排放降低了59.4%,生命周期成本减少了62.3%.得到了适合夏热冬冷地区老旧小区住宅建筑低碳优化组合方案,给决策者在既有建筑改造中提供量化指导.
Energy consumption for building heating and cooling in hot summer and cold winter ( HSCW) area is increasing rapidly,resulting in an increase in carbon emissions. Through simulation experiments,this study takes building carbon emission and economic cost as effect orientation. Based on the existing residential buildings in Suzhou,this study selected the thickness of external wall insulation layer,window type and air tightness as research variables,set up orthogonal tests,and used software simulation to calculate the carbon emission and building life cycle cost( LCC) of each optimization strategy. The results show that from the perspective of reducing carbon emissions,the optimal scheme reduces carbon emissions by 59.4% and LCC by 62.3% compared to the sample building. The low carbon optimal combination scheme for residential buildings in old residential areas in HSCW area obtained can provide quantitative guidance for decision makers in the retrofit of existing buildings.
