摘要

The circular economy (CE) approach has emerged as a potential solution to address the issues of extensive resource consumption and waste generation in the building sector. However, a proper assessment method to measure the extent of the building circularity is lacking. The digitalization of the built environment, particularly through the use of Building Information Modelling (BIM), has proven highly effective in managing large volumes of information and fostering collaboration among stakeholders. This study proposes a novel ‘Building Circularity Assessment Framework’ (BCAF), based on adherence to circular strategies, delivering automated calculation of a circularity index. The circularity data, together with the material details, is stored in a ‘Material Bank’ to facilitate the identification of materials for reuse or recycling at the end of the useful life of the building. The Building Circularity Index (BCI) is calculated as a function of the mass fraction of materials adhering to each circular strategy and its assigned weightage, which serves as a reference for material selection in the design phase and waste processing in the end-of-life phase. The framework is demonstrated using a building model with alternative materials, where the BCI is lowest for conventional materials, moderate for reused and recycled materials, and the maximum for precast construction.
