摘要
确定外墙保温层经济厚度不能单纯考虑高节能率,而忽略初投资。全寿命周期费用分析是一种确定外墙保温层经济厚度的合理方法。以徐州的一栋5层办公楼为研究对象,利用清华大学开发的DeST-c软件对不同的外墙保温层厚度模型进行能耗模拟,并建立了全寿命周期费用计算模型。结果显示,采用聚氨酯泡沫塑料做保温层时,该办公楼外墙保温层经济厚度约为50 mm。
When choosing the economical insulation thickness, we can't only pursue the high energy saving rate but ignore primary investment. The life cycle cost analysis is a reasonable method to choose a economical insulation thickness of the wall. We choose a 5floor office building of Xuzhou as the research object. The software of DeST-c developed by Tsinghua university is used to simulate the energy consumption of the office in different external wall insulation thickness. We established the life cycle cost calculation model. Results show that when using the polyurethane foam plastics insulation, the economical insulation thickness of the office is about 50
