Linking analytic hierarchy process and cluster analysis to weight indicators in residential building energy efficiency assessment

A method is proposed to assign the priority for indicators in this paper. This proposed method combines the group analytic hierarchy process (group AHP) and cluster analysis, therefore, it highlights the democracy and avoids the extreme individual preference in group decision. This method has been used to weight 17 identified indicators for assessing the energy efficiency of residential building in hot summer and cold winter zone in China. The proposed method could also be extended to weight identified indicators of energy efficiency assessment in building in other 4 climate zones in China, even other countries.
