1. Symposium on Sustainable Construction


How can the throw-away mentality of our construction industry be questioned and what ideas oppose the concept of resource destruction?
The symposium take.build.repeat., held at KIT in November 2018, was dedicated to these questions in order to jointly shape the future of construction in lectures and discussions.

The symposium take.build.repeat. was organized by the department of Sustainable Construction at the faculty of Architecture at the Karlsruhe Institute of Technology KIT and held in November 2018.
Through the interdisciplinary exchange of ideas among experts, students, and interested parties, the throw-away mentality of our construction industry that is practiced today was questioned. Resources are extracted, consumed and then disposed. This linear concept of destruction of resources is countered by the idea of closed material cycles, of newly conceived (de-)construction technologies and, in particular, of new business models of recycling management. The symposium was dedicated to the important question of how to build our cities of the future in times of a steadily growing world population and scarce resources without continuing to exploit and pollute our natural environment. The built environment must be both a responsible solution for the present and the material store of the future.

“With a retrospective view of these specialist contributions ChangeLab! would like to pick up the topics of the symposium again and thus stimulate further discourse”.


The one-day symposium brought together representatives from science and industry, theoretical and practical approaches, as well as practitioners and students to jointly shape the future of construction in lectures and discussions.

The speakers were Prof. Dr. Walter R. Stahel (Product Life Institute), Prof. Annette Hillebrandt (University of Wuppertal), Peter van Assche (bureau SLA), Jasper Brommet (StoneCycling), Stefan Rohrmus (Schüco) and Sabine Oberhuber-Rau (Madaster). The recently opened Urban Mining and Recycling (UMAR) Unit in Empa Switzerland’s NEST was also presented in detail by Werner Sobek (Werner Sobek AG / Universität Stuttgart) with Dirk E. Hebel (KIT Karlsruhe) and Felix Heisel (Cornell University).
In the following article and video, Prof. Dr. Werner Sobek presents the fundamental problem of our immense consumption of resources.
