本文介绍了为解决美国小坡度屋面既有建筑节能问题,拜耳材料科技在美国所进行的一项研究及其方法与结果分析。这项研究主要内容包括:使用聚异氰脲酸酯板材为保温隔热材料,每隔20～30年定期更换一次既有建筑物的小坡度屋面,并选取美国能源署(DOE)提供的不同气候带的10种建筑物模型,运用EnergyPlus软件进行小坡度屋面节能改造后的节能效益与环境影响分析。最终得出了这种屋面节能改造将产生巨大的经济效益及大幅减少与建筑采暖与制冷相关的温室气体排放的结论。
This article describes a study conducted by Bayer MaterialScience in the United States to address the issue of energy conservation in existing buildings with small slopes in the United States, as well as its methods and results. The main contents of this study include: using polyisocyanurate sheet material as thermal insulation material, change the small slope roof of the existing building regularly every 20 to 30 years, and select the different provided by the US Department of Energy (DOE) Climate models of 10 buildings, the use of EnergyPlus software for small gradient roof energy saving efficiency and environmental impact analysis. This concludes the conclusion that such a roofing retrofit will have huge economic benefits and will significantly reduce the greenhouse gas emissions associated with building heating and cooling.
