以天津地区某高校教学楼为例，用Designbuilder7.2模拟分析其建筑外墙采用XPS挤塑聚苯板为保温层时的制冷及采暖的耗能量，分析保温层厚度与建筑能耗之间的变化关系；再基于生命周期成本分析法原理，建立材料费用、能耗费用以及保温层厚度之间的数学模型，得出该高校教学楼外墙保温层的经济性厚度，对保温层厚度计算方法的研究及寒冷地区外墙保温层的经济性厚度的选择均具有一定的意义。
以天津地區某高校教學樓為例，用Designbuilder7.2模擬分析其建築外牆採用XPS擠塑聚苯闆為保溫層時的製冷及採暖的耗能量，分析保溫層厚度與建築能耗之間的變化關繫；再基于生命週期成本分析法原理，建立材料費用、能耗費用以及保溫層厚度之間的數學模型，得齣該高校教學樓外牆保溫層的經濟性厚度，對保溫層厚度計算方法的研究及寒冷地區外牆保溫層的經濟性厚度的選擇均具有一定的意義。

Taking a university in Tianjin as an example, the cooling and heating energy consumption of building with external wall taking XPS as insulation layer is simulated with Designbuilder7.2 to study the relationship between thermal insulation thickness and energy consumption, to conclude the economical thickness of thermal insulation on external wall. The economical thermal insulation thickness on external wall is concluded by establishing mathematical model of material cost, energy cost and insulation thickness. The calculation for thermal insulation thickness and the selection of economical thermal insulation thick-ness on external wall in cold area are expounded.
