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.
