Vision for the future reusable buildings High end-of-life value Building owners will be actively engaged in offering reusable components for sale before the deconstruction. Reusable BIM BIM objects for the new building design will be equally sourced from the product manufacturers and second-hand material dealers. Reversible and scalable design Buildings will be designed for deconstruction and reuse. The evolution of future buildings (e.g. in thermal insulation, story height) will be anticipated in the design. 5
Demolition or deconstruction? 6
Focus on single-storey steel buildings Broad applicability (industrial, commercial, sports, exhibition, warehouses), suitable for reuse and viable for circular-economy business models. The results will be easily extendable to other materials and building typologies. Existing and future buildings Reuse of existing building stock is challenging and only marginally profitable.
