Protection of resources through circular design as well as pure and biogenic materials
The integration of 100 % biological insulation materials in circular construction systems is one example for forward-looking solutions for resource-efficient architectures. Currently, the most commonly used insulation materials consist of synthetic or mineral raw materials as well as biobased-synthetic mixtures that cannot be returned to the biological cycle. In contrast to this, the use of biological single-variety insulation materials in combination with reversible construction techniques enables a complete return of the insulations to the biological cycle or a further use in other construction systems.
A part of the research at the Professorship of Sustainable Construction at the Karlsruhe Institute of Technology (KIT) is concerned with resource-conserving use of materials and circular construction principles, which enable dismantling and reuse of the building materials. 100 % biological insulation materials in combination with a reversible construction can be part of climate protection, through the reuse of the insulation materials (saving of primary building materials), a corresponding reduction of primary resources and the reduction of CO₂ emissions through the mostly low-energy production of the biological products.At the BAU 2025 trade fair in Munich Daniela Schneider and Sandra Böhm gave a presentation regarding their current research results and practical applications of these concepts.
