【摘要】：在低碳、绿色、环保、生态成为当代城市文明的主题下,建筑保温材料作为建筑节能最主要的解决途径之一备受关注,以北京市75%节能6层模拟住宅为例,利用DeST-h软件计算得出其墙体传热系数K值为0.40 W m-2K-1,节约电量42.31 kW h-1m-2,通过计算可节约标煤17.09 kg/m2,减少CO2排放量42.19 kg/m2,减少SO2排放量1.27 kg/m2,减少NOx排放量0.635 kg/m2,减少煤粉尘排放量11.5 kg/m2,减少煤烟尘排放5.75 kg/m2,环境效益36.66元/m2。并利用生命周期原理进行简化计算出4种常见保温材料岩棉、XPS、EPS和聚氨酯的50a建筑寿命周期中的总能耗分别为6.55×106、6.63×106、6.58×106、6.77×106kJ/m2,其中不同阶段能耗所占的比例从大到小依次为运行能耗生产能耗运输能耗。保温材料资金回收年限、环境效益回收年限和能耗回收年限的大小顺序:聚氨酯XPS≈EPS岩棉,三者顺序基本一致。并对建筑外墙保温材料科学评价与发展趋势进行探讨。
[Abstract]:Under the theme of low carbon, green, environmental protection and ecology as the theme of contemporary urban civilization, building insulation materials as one of the most important ways to solve the problem of building energy conservation have attracted much attention. Taking the 75% energy-saving six-story residential building in Beijing as an example, The wall heat transfer coefficient K is 0.40 W m ~ (-2) K ~ (-1) and electricity saving is 42.31 kW ~ (-1) m ~ (-2) by DeST-h software. It can save 17.09 kg 路m ~ (-2) 路m ~ (2) of standard coal, 42.19 kg / m ~ (2) of CO2 emission, 1.27 kg / m ~ (2) of SO2 emission, 0.635 kg / m ~ (2) of NOx emission, and 0.635 kg / m ~ (2) of coal dust emission. The emission amount is 11.5 kg / m ~ (2), reducing coal smoke emission 5.75 kg / m ~ (2), environmental benefit 36.66 yuan / m ~ (2). By using the life cycle principle, the total energy consumption in the 50a building life cycle of four common insulating materials, XPS EPS and polyurethane, is 6.55 脳 10 6, 6.63 脳 10 6, 6.58 脳 10 6, 6. 77 脳 10 6 KJ / m 2, respectively. The proportion of energy consumption in different stages is in order of operation from large to small. Energy consumption production energy consumption transportation energy consumption. The order of recovery life of heat preservation material, environmental benefit and energy consumption: polyurethane XPS 鈮，
