Fraunhofer CSE's Building Enclosures and Materials Group focuses on advanced thermal control technologies, applied to building enclosures, their components, and the whole building. The research group develops, designs and analyzes novel thermal insulations, thermal storage materials, radiant insulations, environmental barriers, structural materials and systems, building envelope technologies, controllable building enclosures, and building-integrated solar systems, through numerical analysis as well as laboratory and field testing. In addition, the group works to advance numerical tools for thermal and hygrothermal simulations of building components and whole buildings.
