基于改进TOPSIS的楼宇多指标综合评价

A Comprehensive Evaluation Model of Buildings Based on Improved TOPSIS

为综合评价大型办公楼宇在能耗、环保、经济性等方面的运行情况,提出基于改进灰色关联逼近理想解排序法(TOPSIS)的多指标综合评价模型.在对楼宇运行实际情况分析的基础上,构建包含楼宇运行能耗、环境因素、经济性的多指标评价体系;引入改进TOPSIS评价方法,利用灰色关联度算法和层次分析法-熵权法确定TOPSIS评估模型距离测度;建立楼宇多属性加权评价模型,全面分析楼宇运行状况.分析8栋电力办公楼宇单元的多指标评价可知:楼宇综合评价结果随时间变化,能耗指标评分起主要作用;与采用其他评价方法的评价结果进行对比,验证了所提楼宇多指标评价模型的有效性.

In order to evaluate the operation of energy consumption,environmental protection,and economy,a multi-index comprehensive evaluation model based on an improved technique for order preference by similarity to ideal solution(TOPSIS)is proposed.Based on the analysis of building operation,a multi-index evaluation system is constructed.Then,an improved TOPSIS evaluation method is introduced and a distance measure of the TOPSIS evaluation model by the gray correlation algorithm and analytic hierarchy process(AHP)-entropy weight method is determined.Next,a multi-attribute weighted evaluation model is established to analyze the building operation comprehensively.The multi-index evaluation of eight power office buildings indicates that the building comprehensive evaluation results vary with time and the energy consumption index score plays the main role in all indexes.A comparison of the evaluation results with those obtained by other evaluation methods verifies the effectiveness of the proposed building multi-index evaluation model.
