A great example of a circular renovation project is that of the Huthmacher-Haus on Hardenbergplatz in Berlin. Listed as a monument, this striking office tower has some 15,800 m² of floor space spread over 15 floors. The historic building is currently being renovated by Bayerische Hausbau, one of Germany’s largest integrated real estate companies. The data will be collected by EPEA GmbH (part of Drees & Sommer) and uploaded to the Madaster Platform. A touch of a button provides access to information on the carbon footprint, circularity and financial salvage value of materials. This enables 24/7 determination of the disassembly potential and reusability of raw materials. This particular renovation project proves that, with the help of digitisation, the consumption of new raw materials can be kept to a minimum.
