Abstract: Now how to correctly choose many different kinds of building performance analysis software is a hotspot of the research.This paper summaried them at present, combined the common problems in the research of software evaluation method and used the analytic hierarchy process(AHP) and fuzzy mathematics method to evaluation standard of software use fuzzy processing.Through establishing evaluation system based on software of ISO/IEC9126, using the analytic hierarchy process(AHP) to determine the index weight, and fuzzy comprehensive analysis method is adopted to realize the selection of them.It provided a reference to select them for designers in the early design stage.
