Research:
Circular economy (CE) principles have been given increasing attention in the construction domain when stakeholders seek various solutions to reduce carbon emissions. Reusing and recycling construction materials are considered two prominent CE strategies, however, the existing body of knowledge lacks an operational perspective with which stakeholders will fit the strategies successfully into construction. Whether stakeholders can efficiently reuse and recycle construction materials depends on the efficiency of the storage and tracking of material passport information, which represents an electronic set of data about materials, products and components for circular use. To address this challenge, this research project focuses on the development of a digital passports interface in BIM authoring software to enable project stakeholders to access and document the reusing or recycling potential of specific types of materials. The interface will serve not only as the basis for the identification and quantification of reused or recycled materials at the end-of-life stage of existing buildings but also as the toolkit for the design of future decarbonized buildings.
