In this event, we would like to stimulate a discourse on the current problems in the use of concrete, the current and future possibilities of recycling old concrete into new concrete, as well as new application concepts and production formulations for concrete.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Mag. Arch. Roland Gruber gave a lecture about cities expanding and growing at the outer edges while city centers are constantly becoming emptier and calmer.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Prof. Dr. Philippe Block gave a lecture about how existing construction principles could be applied in a much more material- and resource-saving way in the future - by the application of the "strength through geometry" principle.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, M. Sc. Dominik Campanella gave a lecture about about the digital documentation of materials for the establishment of reuse in the construction sector.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Dipl. Kfm. Daniel Fuhrhop gave a lecture about the hidden living space in existing buildings that can be easily found and recreated by introducing social programs - without harming the climate or constructing new buildings.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Prof. Thomas Auer gave a lecture about the energy performance and climatic robustness of old, refurbished and new building structures.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Dipl. Ing. Arch. Kerstin Müller gave a lecture about the manifold possibilities between demolition, preservation and further construction of existing buildings.

At the symposium sustain.build.repeat., held by the KIT Faculty of Architecture in April 2022, Prof. Dipl. Ing. Tina Kammer gave a lecture about the ongoing deep changes across the design, construction, use and reuse of buildings: about building better, less and differently.

Many exciting speakers were guests at the 2022 sustain.build.repeat symposium, which was held at the ZKM and livestreamed under the management of PINK Event Service. The event was organized by the KIT Professorship of Sustainable Construction with the kind support of Wacker Chemie AG. In order to revisit the contents of the symposium, a podcast was recorded in cooperation with Campusradio Karlsruhe.

See some impressions of the event here. We would like to sincerely thank all those involved in the event for their commitment and organisational efforts, for the great encounters, conversations and new connections that were created at and through the symposium.

We are very pleased to announce our 3rd Symposium on Sustainable Construction on the 29th April 2022 in the ZKM Medientheater in Karlsruhe and online. The event is organized by the Professorship of Sustainable Construction and is being held with the kind support of Wacker Chemie AG.

In the two buildings of the Department of Architecture at KIT, the Symposium "sustain.build.repeat. - building stock as the resource of the 21st century" is currently being announced with many posters.
