节能视角下的泡沫混凝土外墙厚度选择及分析

The Selection and Analysis of the Economic Thickness of Foam Concrete Wall from the Perspective of Energy Saving

该文以泡沫混凝土材料作为外墙自保温材料,结合武汉某住宅建筑实例,借助DeST-h能耗模拟软件,以未保温墙体作为基准模型,通过比较几组不同厚度的自保温墙体,以净现值为评价指标确定了泡沫混凝土自保温墙体的经济厚度;借用minitab16软件的曲线拟合功能,计算分析了泡沫混凝土自保温墙体的最佳经济厚度,为泡沫混凝土作为建筑节能墙体材料进一步发展提供指导性的意见.图2,表3,参7.

This paper has researched the foam concrete material as the external wall insulation materials,which Combined with the example of a residential building in Wuhan. Using DeST-h software,with no insulation wall as the benchmark model,through the comparison of several groups different self thermal insulation wall thickness,the economic thickness of foam concrete insulation wall with net present value was determined as evaluation index. Using the curve fitting function of minitab16 software,the optimum thickness of foam concrete insulation wall was analyzed and calculated,which will provide further development guidance for foam concrete as a building energy-saving wall materials. 2figs.,3tabs.,7refs.
