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 furthe...
