摘要
为研究北方寒冷地区老旧住宅建筑外窗节能改造前后的耗热量指标、节能率、经济性及碳排放量,构建建筑模型,对市面上常见的7种类型外窗进行模拟计算。结果表明:更换为节能外窗后,建筑的耗热量指标均降低,节能效果提高;改造后建筑运行阶段的碳排放量均有所降低,具有良好的碳减排效果;选用隔热铝合金窗6 mm+12 mmAr+6 mm+12 mmAr+6 mmLow-E进行节能改造的经济性最好。
In order to research on the heat consumption index,energy saving rate,economy and carbon emission before and after the transformation of the exterior windows of old residential buildings in cold areas in northern China,build a building model,by selecting seven types of exterior Windows commonly available on the market and carried out simulation calculation to analyze.The results show that the heat consumption index of buildings is reduced and the energy saving effect is improved after the replacement of energy-saving exterior Windows,after the transformation,the carbon emissions in the operation stage of the buildings are reduced,which has a good carbon emission reduction effect,the thermal insulation aluminum alloy window 6 mm+12 mmAr+6 mm+12 mmAr+6 mmLow-E is used for energy saving transformation is the best.
