Evaluation of Residential Energy-Saving Buildings Based on Grey Relational Analysis Method

Abstract

Energy-saving design is the key factor for buildings, and there is no unified approach that can effectively assess the energy efficiency of residential design. On the basis of the characteristics of complexity and the uncertainty of optimal selection for energy-saving building designs, grey relational analysis model in energy-saving buildings multidesigns selection application has been put forward in this paper. The index system of influencing energy-saving buildings design selection is determined. Application model and procedures of the grey relational analysis method are introduced. According to the degree how close it is with the ideal dot, the optimal design is easy to be selected out. Through the optimization analysis design selection for energy-saving building designs, it is proved that the optimal design selection for energy-saving buildings based on grey relational analysis has the strong recognition judgment ability. It is convenient, quantitative, and strict. It provided a possible new way for evaluation of energy-saving building design selecting.
