Study on Residential Building Energy-saving Comprehensive Evaluation System in Hot Summer and Cold Winter Zone Based on AHP

A new evaluation method was proposed for hot -summer and cold -winter zone, which based on domestic and foreign energy-saving standard and evaluation technology as well as the current situation. The residential building energy-saving system evaluation model was established by referencing the AHP method model, its weight of each evaluation index came from the experts' investigation method, and was modified by entropy technology to index. The results show that, this method can not only simplified the qualitative and quantitative evaluation index quantification process but also improve the whole evaluation system operability. At last, we made a empirical analysis and evaluation of comprehensive of a small unit residential in Lu'an, the result shows that although the residential building energy conservation in the basically meet the national building energy efficiency requirements,it still needs to be improved in some other aspects.
