Simulation of Matter-Element Extension Model for Building Energy Efficiency Evaluation
In order to obtain accurate energy consumption and promote reasonable resource conservation,a method of assessing the energy-saving effect of buildings was studied with the help of the matter-element extension model.Firstly,we constructed an evaluation index system to quantitatively represent the progress of the project,the amount of energy saving and emission reduction.Secondly,we used the subjective assignment method to qualitatively evaluate the degree of success of the project and thus to determine the categorization criteria.Thirdly,we introduced the exten-sion principle into the evaluation of building energy-saving effects.Then,we used the matter-element matrix and cor-relation function to clarify the matter-element to be evaluated.Moreover,we determined the weight coefficient of the evaluation index and eliminated the external interference of index weight,thus reducing evaluation error.Furthermore,we divided the regions of grading optimization,and used the known feature weight coefficients to calculate the correla-tion of the evaluation objects.Finally,we completed the comprehensive evaluation of the energy-saving effect of buildings.Experimental results show that the proposed method can effectively evaluate the energy-saving grade of dif-ferent buildings,and calculate energy consumption accurately,so it is conducive to improving the energy-saving effect of buildings.
