Climate adaptability, including the adaptation to the daily climate, the readiness to face natural calamities, the nurturing of long-term resources and the environment, are part of the goal of building green retrofitting. Setting retrofitting evaluation standards should consider regional diversification due to varying local climate conditions. Based on the entropy method and fuzzy analytic hierarchy process (FAHP), this study proposes a weight correction system to correct the weights from China?s Assessment Standard for Green Retrofitting of Existing Building. By comparing the corrected weights to the original weights, recommendations for building green retrofitting measures in seven climate zones were put forward. The results indicate that priority should be given to the selection of materials and building envelopes and that site design is the basis for the building climate adaptability. It is imperative that equipment transformation is carried out in cold area and severe cold area. Comprehensive energy and non-traditional water sources can be used in hot-summer and cold-winter area, hotsummer and warm-winter area and mild area. Our research findings can improve the climate adaptability of building retrofit according to regional characteristics while circumventing low-efficiency measures. Furthermore, we discussed the possibility of extending the proposed weight correction system to other countries? standards.
