The research of applying TOPSIS combined with grey relational analysis approach for building energy consumption evaluation

Abstract

In this paper, besides defining the positive "ideal building," an approach combined TOPSIS with grey relational analysis method is introduced into the field of architecture. This improved method can reflect the exact energy consumption close degree of each building for evaluation to the positive "ideal building" from both aspects of position distance and shape similarity. Due to the energy consumption relative closeness degree of buildings to the positive "ideal building," not only each building energy consumption level can be determined precisely to rank multiple existing building energy consumption levels, but the qualities of each building index can be assessed effectively. At last, taking a simple evaluation system as an example, three urban building energy consumption levels are compared through the selected system. Through the case analysis, the superiority and effectiveness of the new method for building energy consumption evaluation are proved. © Springer-Verlag Berlin Heidelberg 2014.
