Evaluation of Factors Affecting the Successful Implementation of Green Buildings Based on the Combined Fuzzy DANP and IPA Approach

Abstract

Green buildings play a key role in the sustainable development of the construction industry, helping reduce environmental impacts and optimize energy consumption. This study is aimed at evaluating the factors affecting the successful implementation of green buildings using a combination of the fuzzy Delphi method, fuzzy DANP, and Importance-Performance Analysis (IPA). The statistical population includes ten experts from Simin Stone Façade Construction Company, selected through purposive sampling. The research findings indicate that environmental benefits, energy consumption, resource utilization, and economic benefits are among the key factors affecting the success of green buildings. The fuzzy DANP analysis results show that energy consumption is the most influential factor on other indicators, while waste generation has the highest interconnection with other factors. Furthermore, the IPA analysis identifies waste generation as a critical weakness requiring immediate improvement. By presenting a comprehensive evaluation framework, this study can assist policymakers and construction industry stakeholders in optimizing the design and implementation of green buildings.
