Comprehensive Evaluation on Performance of Existing Residential Buildings Based on Fuzzy and Analytic Hierarchy Process

Abstract:

On the purpose of improving performance of buildings through complex refurbishment,the performance of existing residential buildings in this paper is measured by six indicators such as security,intactness,fittingness,energy-saving,dwelling environment,and coordination.In order to overcome the shortcomings of random and subjectivity in the traditional evaluation method and to eliminate the uncertainty during the evaluation process,a comprehensive model for evaluating performance of residential buildings is proposed,where the weight of each indicator is determinate based on an improved analytic hierarchy process (AHP) method combined with fuzzy analysis of the relevant relationship of each indicator.The case of 30 different residential buildings is evaluated and then reveals many advantages in this model that evaluation is comprehensive,objective,and operational.By discussion of case study in the end,several reconstruction approaches are proposed in improving performance of existing residential buildings.
