The Urban Mining Index (“UMI”) was developed by Dr. Anja Rosen as part of her doctoral thesis at the University of Wuppertal. Prof. Annette Hillebrandt supervised the researchwork.

Additional reviewers were Prof. Dipl.-Ing. Dirk E. Hebel of the Karlsruhe Institute of Technology (KIT) and Prof. Dr. Ing. Klaus Sedlbauer of the Technical University of Munich (TUM). Under the chair of Prof. Dr. Ing. Karsten Voss, the doctoral thesis was awarded “summa cum laude” by the examination committee in September 2020.

Currently, a team at the University of Wuppertal (BUW) is working on user-friendly software to use the “UMI” in the context of the Urban Solar Decathlon 2021.
