Research on green assessment method for prefabricated buildings

Abstract

In view of the problem that the current evaluation of prefabricated buildings in China focuses more on the ‘assembly rate’, this paper puts forward a green assessment method suitable for prefabricated buildings in China, which determines the evaluation index system according to four aspects: green design, intelligent construction, assembled building quality and comprehensive benefit. In addition, the decision making trial and evaluation laboratory method is used to optimise the index weight, and then the analytic hierarchy process–entropy weight method is used to determine the weight of the index system, and the evaluation index set is quantified and graded. Finally, taking the Hutuo Village public rental housing project in Xi’an City of Shaanxi Province as an example, this paper uses the evaluation method to conduct a green assessment and gives suggestions for improvement in each stage of the project.
