Fuzzy gray clustering evaluation of green building operation effect: a case study of Shenzhen Bay One, China

Abstract

PurposeThis paper improves the evaluation index system of green building operation effect and establishes the evaluation model of green building operation effect. It is expected to promote energy saving and emission reduction and provide a more scientific evaluation method for green building operation effect evaluation.Design/methodology/approachFirst, 20 key evaluation indexes are selected to establish the operation effective evaluation index system. Then, the combined weight method is proposed to determine the weight of each evaluation index. Next, the gray clustering-fuzzy comprehensive evaluation method is used to construct the green building operation effective evaluation model. Finally, the feasibility and validity of the selected model were verified by taking Shenzhen Bay One green building in Shenzhen as an example.FindingsThis paper establishes the evaluation system of green building operational effect, and evaluates green building from the angle of operational effect. Taking Shenzhen Bay One project as an example, the rationality and applicability of the model are verified.Originality/valueIn this paper, for the first time, relevant indexes of user experience are included in the evaluation system of green building operational effect, which makes the evaluation system more perfect. In addition, a more scientific fuzzy gray clustering method is used to evaluate the operational effect of green building, and a new evaluation model is established.

A Combined MAGDM-Based Framework Employing EDAS and CRITIC Techniques for Green Building Technology Schemes Evaluation

“…However, at present, the evaluation of green building technology and economic evaluation is more focemployed on the overall level. Although this concept can to some extent meet the current needs for promoting green buildings and facilitate owners to identify the advantages of green buildings, from a specific work perspective, this approach is relatively one-sided and easy to create a certain illusion for people [62,63]. At the same time, it also allows for the creation of conditions for different violations, which is unfavorable for promoting the development of the entire industry.…”
