An integrated planning team must break new ground for the development of recyclable buildings. The BIMaterial research project developed the implementation of building-material-passports as a planning and documentation tool with the aim of establishing an urban-material-inventorie. The Design2Eco research project shows that interior design in particular has an increasing demand for flexibility and adaptability, which means that the consumption of resources is growing exponentially due to frequent tenant changes. These findings are currently being incorporated into the planning of an innovative pilot project, in which the core task is the reuse of components up to the development of Madaster. This will be evaluated by taking into account the results of life cycle assessments, life cycle costs and residual value analyses.
