Abstract
The construction industry is increasingly adopting sustainability and circularity principles to improve resource efficiency, minimise waste, and promote reuse. Despite this progress, integrating circularity attributes of existing buildings into 3D digital models remains challenging. This study, part of the EU-funded SUM4Re project, reviewed the literature on the intersection of Building Informa-tion Modelling (BIM) and circularity to identify a comprehensive set of circularity parameters for BIM integration. Analysis of key national frameworks and circu-larity index tools revealed a lack of harmonised criteria and methods for assessing building circularity across countries, limiting consistency and knowledge transfer. Additionally, a review of 14 scientific articles examined BIM’s role in managing circularity-related data. While research provides valuable insights, findings remain fragmented and do not cover all BIM-required data. To address this, a structured taxonomy of additional sustainability and circularity parameters for BIM integra-tion was developed through a three-layer review. The parameters were grouped into seven categories covering core attributes at the building-or product-level. Classifying these parameters as mandatory or optional could streamline data col-lection and BIM integration. In addition, advanced technologies such as laser scanning and computer vision could automate parameter assessment, improving both accuracy and efficiency.
