Building passports and digital twin

Make a digital twin (e.g. BIM model) of the building project to store and share quantitative and qualitative data, and to get quick feedback on design changes. Make material/ building passports of the materials and elements in the building and couple it to the digital twin. Storage of data can facilitate maintenance and reuse in the future.
