BIM Integrated LCA for Promoting Circular Economy towards Sustainable Construction: An Analytical Review

Abstract

Sustainable construction is widely regarded as one of the best decisions to reduce the environmental impact of the buildings. Numerous scientific efforts have been devoted to promoting sustainability by adopting different techniques such as life cycle assessment (LCA) and building information modeling (BIM). The recent circular economy (CE) agenda is prioritizing in different sectors including construction due to increasing concern on the materials efficiency and resources consumption. Therefore, this study aimed to identify the implications, considerations, contributions and challenges of BIM integrated LCA and the CE adoption in the industry by critically analyzing the recent literature. A scientometric analysis was applied to the selected studies to show the knowledge among BIM, LCA and CE relationships. With a comprehensive analysis of major challenges and opportunities of LCA and BIM for construction sustainability, key drivers for sustainable building design were identified and analyzed. A prospective integrated framework for CE adoption into BIM-based LCA of buildings and an evaluation method are proposed by analyzing the contemporary issues. It is believed that the analyzed critical issues, identified future research direction and proposed frameworks and this methodology should contribute to effective implementation of CE into the building for promoting sustainable construction.
