A Bibliometric-Systematic Analysis Of Post-Occupancy Evaluation Of Green Building Using Bibliometrix R-Tool

Post-occupancy evaluation (POE) is an essential tool to gather data from occupants regarding their dwelling conditions to inform retrofit decisions or improve future performance. With the growing importance of green building (GB) as a potent mechanism to address sustainability challenges within the construction industry, research on POE-in-GB is critical. However, there has been little effort to provide researchers with a systematic and bibliometric analysis of the state-of-the-art of the POE-in-GB field. To address this gap, this study uses bibliometric-systematic analysis to conduct a state-of-the-art review of POE-in-GB. A dataset comprising 183 publications from 1999-2023 was collected from the Scopus and Web of Science databases. The data was analyzed using VOSviewer, Gephi, and Bibliometrix. As expected, results revealed an upward trend in publications on POE-in-GB. These publications involve the contributions of 424 authors from 84 outlets. Keyword co-occurrence analysis revealed that the most significant keywords and hotspots in POE-in-GB research include “indoor environmental quality (IEQ)”, “occupant satisfaction”, “Leadership in Energy and Environmental Design (LEED)”, “building performance assessment”, “sustainable building”, and “thermal comfort”. A further qualitative systematic analysis of 50 screened research publications revealed some knowledge gaps and future research directions of POE-in-GB, including socio-psychological factors in POE-in-GB, standardizing protocols, aligning GB certifications to user satisfaction, and technology and big data integration in post-occupancy studies. This study contributes to the knowledge domain of GBs and POEs by providing a state-of-the-art review of the area and identifying research gaps to improve sustainability and efficiency within the architecture, engineering, and construction, operations (AECO) sector.
