Risk management in green building: a review of the current state of research and future directions

There has been considerable interest in investigating risk factors in Green Building (GB) projects, with increasing debates in recent years. This study aims to investigate tendencies and identify gaps in the GB risk literature, which can define future research guidelines, with an extensive analysis of the latest contributions. A systematic literature review was conducted by analyzing 64 relevant studies from 2006 to 2020. The results revealed that the GB risk topic is somewhat nascent but growing and almost limited to several countries, including Singapore, the USA, Australia, and China. Notably, this research discovered and classified the main themes of GB risk studies: (1) identify risk factors in implementing GB projects, (2) create risk assessment models for GB projects, (3) study according to specific types of GB risks, and (4) investigate risks in green retrofit projects. Also, a comprehensive list of GB risk factors was provided that could be a helpful reference for industry prac- titioners and future researchers. Furthermore, this research identified gaps in the current literature, such as inconsistency in identifying GB risk factors, lack of investigation of the relationship between GB risks and project outcomes, and lack of exploring in cross-coun- try or developing countries. Finally, this research suggested future research directions to enrich the literature. Thus, this study contributes a valuable platform for both practitioners and researchers to comprehend the development of the GB risk literature.
