Contribute to knowledge about risks in implementing Green Building projects in developing countries: a case of Vietnam

In recent years there has been significant interest in investigating risks linked to the implementation of Green Building (GB) projects that are in line with the developing trend of sustainable construction over the world. In an attempt to contribute to GB risks literature, this study explored risk factors that GB projects frequently confront in Vietnam. This study firstly conducted a comprehensive literature review to generate a preliminary list of risk factors. These risk factors were then confirmed and complemented by interviewing ten experts in the field. After that, the research assessed the risk factors by surveying 119 construction professionals to discover the most critical GB risks. Notably, this paper considered the effect on the risk assessment process of GB experience and project roles. Results showed that "The owner lacks determination,""Late involvement of GB consultants,"and "Project evaluation result did not reach the expected GB standard"were the top three critical risks in GB projects. The statistical analysis also revealed that the assessment of GB risk negatively correlated with participants' GB practical experience. Furthermore, hierarchical moderated regression analysis exposed differences in the risk assessment between various project roles, though these differences were relatively small and not statistically significant. By investigating GB projects' main risks, this paper may become a useful reference guide within the construction sector. This research also enriches the literature by contributing empirical evidence of risk assessment in GB projects in a developing country.
