Research on indexes and weight of green retrofitting for existing buildings

Considering the current situations in China, establishes the index system of green retrofitting for existing buildings by referring to the advantages of foreign standards of green operation and retrofitting for existing buildings. With the group decision analytic hierarchy process method, develops the judgment matrix and calculates the weight values by questionnaires. The results show that the consistency of the judgment matrix is acceptable. Furthermore, evaluates the retrofitting projects of existing building by the index system, and also compares the evaluating results with those by Assessment standard for green building (GB/T 50378-2014). The comparison results indicate that the index system and weight are scientific, reasonable and applicable.
