Assessing the implementation of BIM for enhancing green building certification evaluations

Green building-related certifications ensure construction safety, quality, and sustainability by following approved conditions and specifications. This study provides a nuanced perspective on how Building Information Modeling (BIM) evolves into a dynamic tool for ongoing building performance management. Enhancing the BIM framework with innovative metrics can improve green building ratings and provide operational cost savings for developers and clients. This framework facilitates the development of standardized practices and best guidelines for integrating BIM with green building certifications, streamlining the process and making it more accessible to a broader range of projects. The study examined hypotheses using advanced statistical structural regression modeling (SEM) and implemented the bootstrapping methodology with 5000 random samples to ascertain the significance of the path coefficient. A mega project is being re-evaluated to illustrate the extent to which the implementation of BIM can enhance Green Building Index (GBI) scores. The findings indicate that BIM can enhance sustaining green certification criteria. Furthermore, a slight change in intermediary indicators within a 5% range under the rating system can impact the overall score by approximately 15-20%. Results indicate satisfactory BIM performance, with an R-2 value of 0.405, which is significant for utilizing BIM in GBI valuation across all hypothesized model path coefficients.
