Renovation of Existing Residential Communities Using Green Energy Conservation Technology

Nowadays, in the process of rebuilding old communities, we still face various difficulties such as financing and negotiation. One of the reasons is the lack of green retrofitting awareness of residents. This study tries to develop a green retrofitting evaluation framework that is used by the residents so that they know the renovation problems the community has encountered. Through expert interviews and literature reviews, the criteria and the sub-criteria in each criterion in the retrofitting evaluation framework were developed first. Then, the Delphi expert questionnaires were used to determine the final evaluation framework, which consisted of five criteria and eighteen sub-criteria. The five criteria were energy utilization, water use, waste minimization and recycling, public facilities, and ecology. Thereafter, the Analytic Hierarchical Process (AHP) was used to understand the importance of each obtained sub-criterion by finding its absolute weight. Finally, each factor was applied to an old community in Zhangpu County, Fujian Province, China to diagnose the renovation problems encountered and the renovation strategies were proposed using available green energy conservation technology.
