基于AHP-熵权-可拓学的高校建筑电气节能评价

Electrical Energy Efficiency Evaluation of University Buildings Based on AHP-Entropy Weight-Extension Integration

针对高校能源消耗过高以及浪费严重的问题,提出了一种基于层次分析法、熵权法与可拓学理论融合的高校校园建筑电气节能评价模型。运用可拓学理念,给出了用于评估电气节能性能的物元模型;建立电源节能、电网节能、负荷节能、建筑体系节能为准则的评价体系,选取12个评价指标并引入层次分析法与熵权法计算各评价指标的权重;结合所建立的物元模型构建经典域、节域完成关联度计算。以某高校为例,利用所构建的评价模型完成对其建筑电气节能空间的评价,得到该高校校园建筑电气节能空间为中等级别,其级别特征值为2.90,结果表明其仍存在较大的节能空间,最后根据评价结果提出相应的改进措施。

A methodology for electrical energy efficiency assessment of college campus buildings is proposed.The method is a fusion of AHP,entropy weight method and extenics,aimed at tackling the challenges posed by high energy consumption and significant waste in university environments.Using the concept of topology,an object-element model for evaluating electrical energy-saving performance is given;Construct an evaluation system based on the principles of power supply energy conservation,power grid energy conservation,load energy conservation,and building system energy conservation.12 evaluation indexes are selected to utilize AHP and entropy weighting method to calculate the weight of each evaluation index,combining the established matter-element model to construct the classical domain and nodal domain to complete the correlation calculation.Taking a certain university as an example,the evaluation model constructed was used to evaluate the electrical energy-saving space of its buildings.It was found that the electrical energy-saving space of the campus building in the university is of a medium level,with a level characteristic value of 2.90.The findings show that there is as usual room for greater energy savings,and corresponding improvement measures are proposed based on the evaluation results.
