The growing importance of ESG consideration in the real estate sector has underlined the need for efficient data collection, validation and quality assurance. The complexity of ESG assessment is driven by the nature of the data required for accurate reporting. This study employs the BIM methodology to streamline and enhance ESG assessment in the real estate sector, aiming to promote credibility in ESG assessments of development projects. The primary objective of this thesis is to present a BIM-based ESG assessment workflow that enhances the understanding of how BIM can be integrated with ESG matrices in development projects. This involves identifying the potential applications of BIM in facilitating ESG indicator assessments, defining the necessary information requirements (both geometric and semantic), identifying suitable software tools that can aid the assessment process, determining the appropriate BIM implementation (Open BIM or Closed BIM), and interoperability. This thesis is based on the theory that combining BIM and ESG assessment can result in more precise and reliable evaluations of ESG indicators for development projects. A multifaceted methodology is employed, which involves a systematic review and analysis and the execution of qualitative interviews. The systematic review and analysis consist of studying the current BIM implementation for sustainability evaluation and analysing the GRESB development indicators to determine the potential assessment of the indicators within the BIM framework. On the other hand, the qualitative approach involves interviews with ESG analysts from real estate companies to understand their ESG assessment methodologies and challenges, and with building planners and consultants to explore their BIM workflows for sustainability evaluations. Findings from the analysis of GRESB development indicators revealed that BIM can support the assessment of 11 out of 21 indicators. A potential GRESB score of 28.50 out of 70 can be achieved, which equates to a 40.71% fulfilment rate of the total GRESB development component. The interviews with building planners highlight their diverse approaches to sustainability evaluation. Their presented workflow was analysed for potential assessment of the GRESB development indicators. The findings revealed the assessment of 6 indicators with a GRESB score of 17.25, reflecting a 24.64% fulfilment rate of the GRESB development component. This highlights a potential gap in fully harnessing BIM's capabilities for broader sustainability criteria. This research validates the theory that BIM can enhance the assessment of specific ESG indicators in real estate development. By focusing on GRESB indicators and integrating BIM workflows, this research offers a pathway to improve the efficiency of ESG assessments in a BIM workflow, contributing to a deeper understanding of how BIM can be leveraged for ESG assessments.     «
