FUSION less: A plea for less | less:Demolition | Theresa Keilhacker

With Theresa Keilhacker, President of the Berlin Chamber of Architects

Kick-off event // Presentation of the "Fusion" series

Demolition moratorium

In 2021, 230 million tons of construction and demolition waste were generated in Germany, accounting for 55 percent of all German waste. In September 2022, a broad alliance of architects*, urban planners* and theorists* wrote an open letter to Federal Minister Klara Geywitz calling for a demolition moratorium. This temporary halt to demolition should be used to work out ecologically and socially sensible criteria together with many stakeholders, under which the current practice should be possible in the future to a very limited extent.


FUSION Wi­Se 2022/23

The climate, biodiversity and energy crises are forcing us to radically question current building practices. Fusion Conversations 2022/23 introduces actors who are using unconventional concepts and ideas to advocate for a true building and mobility turnaround, other forms of city and landscape, and contemporary teaching. On the occasion of the 50th anniversary of the ASL department, Fusion continues the long tradition of progressive ecological positions of the University of Kassel and updates them for the present. less: is a plea for less: less cars, less demolition, less concrete, less CO2, less environmental destruction, less sealing, less exploitation, less capitalism. The role of urban and architectural professionals will change dramatically in the coming years. To ensure adequate education, we need more courage for experiments, interdisciplinary teaching concepts and a de-hierarchization of structures. The Fusion Talks want to unfold a utopian potential and give courage to change things ourselves.


Fusion 2022/23 is conceived and organized by the student project group Less:ON and the FG Architectural Theory and Design.

Wednesdays between 7 and 9 pm, 26.10.22 - 01.02.23
Room 106, new building ASL, Universitätsplatz 9, Kassel. Free admission. The event is recognized by the Chamber of Architects as continuing education.

Zoom livestreaming is available for each event.
