Decision-making in design of circular buildings. Information on materials in BIM tools

The growing EU push for the implementation of the circular approach in the building sector induces to rethink the way in which data on materials are collected, shared and used, making them usable in tools that facilitate design and decision-making for resource efficiency. In fact, current support tools do not allow easy access to data on materials in all phases of the life cycle / construction process. This contribution focuses on the importance of integrating datasets on the materials of existing buildings (“Material Passports”, BIM models obtained from surveying with drones) and user supplied information (“harvest map”, boosted with BIM-GIS interoperability) in new methodologies, integrated with LCA and BIM compliant, able to support the design of “circular buildings”.
