KartAL IV - Mapping the anthropogenic material stock IV

Development of a building passport and cadastre concept for the rationalized identification of material stocks and flows in order to optimize recycling.

The primary motivation for this research project is to develop and realize an urban mining strategy to exploit the potentials for resource conservation in the production, use and demolition of buildings as well as related inflows, stocks and outflows of materials within the construction sector. To this end, information gaps will be explored that hinder implementation of a more circular anthropogenic metabolism in the construction sector.

Informational tools will be designed to help fill these gaps. Instruments to document material stocks and flows will be developed and tested from the level of individual projects up to the regional level. The intended results are a material passport for buildings and a material cadastre for settlements. To achieve this, the following questions must be answered:

  1. How should we structure the supply of information on the existing building stock and dynamic changes to this stock through a wide variety of construction activities? What sources of information are available and how much effort is involved in its evaluation?
  2. To whom is this information directed? Which objectives, interests, tasks and instruments do the individual groups of actors pursue and where can these be linked in order to provide more effective support?

Two research strands are pursued at different scales and applied to defined interfaces: A material passport for objects and a material cadastre for regions. The central methodological demand is for practical relevance and easy implementation. In order to ensure this, the project pursues a case study approach involving practitioners. Case studies are employed to identify potential sources of information and to define requirement profiles, providing a solid basis for the development of informational tools, which can then be validated by means of case studies.
