In order to develop strategies for the implementation and establishment of a sustainable and future-oriented material flow management (urban mining, landfill management, waste management, etc.) in Bavaria, the material composition of the building stock must be surveyed over a large area as a first step. Therefore, the feasibility of an area-wide mapping of the anthropogenic stock, in particular the built-up materials in the residential building stock in Bavaria and the material flows to be expected from it, will be investigated within the scope of this project. Here, the aim is to bundle the methods and previous findings on material flow models developed at the Chair for Energy Efficient and Sustainable Planning and Building (ENPB), to expand them and to adapt them to regional conditions. This means that an interface will be created to link typical material parameters with representative 3D building models so that large-scale extrapolations can be carried out in a further step. In addition to the common mineral and metallic materials, the possibility of recording potential building pollutants (e.g. asbestos) or other influencing factors will also be discussed. This should make clear which secondary raw materials are theoretically usable. Furthermore, this study contributes to the definition of all building data required for a raw material mapping, thus creating a basis for a Bavaria-wide uniform data collection. A Bavaria-wide uniform survey of building data can also be used in subsequent studies for other projections, such as life cycle assessments.
