In recent years, an increasing number of Ulrich Müther's shell structures have been listed as historical monuments, renovated, and revitalized. Four recent projects, originally built between 1966 and 1972, stand out as exemplary. In these cases, new facade design solutions and heating/ventilation concepts were implemented to optimize energy efficiency and prevent condensation damage. A new, carbon-based technology was used for the first time in the renovation of concrete shells. These innovative concepts and solutions are systematically recorded and evaluated in this research project. In addition, the perspectives of participating experts from the fields of historic preservation, building physics, and architecture are being gathered. The results will be presented in the form of drawings and written recommendations to support the planning of future, comparable renovation projects.
A summary paper in English will be published in the Conference Proceedings of the IASS 2025 conference “The Living Past as a Source of Innovation.”
