模糊综合评价模型在既有居住建筑节能改造方案评价与优选中的应用研究

An application research of the fuzzy comprehensive evaluation model in the evaluation and optimization scheme of existing residential buildings' energy saving reconstruction

针对既有居住建筑节能改造时存在多种备选方案的问题,提出了一种基于模糊层次分析法的多目标决策问题解决方案.首先,运用层次分析法设计了既有居住建筑节能改造方案评价指标体系,然后建立了模糊综合评价模型,通过该模型在湖南省屋顶节能改造方案选优排序中的应用实例分析,证明了该方法在既有居住建筑节能改造方案评价与优选中的可行性,实现了定性分析与定量研究的有效结合.

Aiming at the existing problem of choice alternatives of residential building energy saving reconstruction,this paper proposes a fuzzy AHP based on multi-goal decision problem solution. Firstly,the analytic hierarchy process is used to design both the appraisal index system of residential building energy saving reconstruction,then set up a fuzzy comprehensive evaluation model. Through the analysis of an application example of the model in the energy saving project of Hunan province roof-ordering selection,the feasibility and practicality of the method in the evaluation and selection of scheme of residential building energy saving reconstruction are proved,combining qualitative analysis and quantitative research effectively.
