The building envelope has diverse functions and tasks:
Modern glazing and thermal insulation systems not only protect the user against climatic influences, but also contribute to solar heating, thermal insulation, daylighting and ventilation with fresh air. Optimisation of thermal and visual comfort with architecturally and economically convincing solutions is the objective of developments which are carried out together with industrial partners in this sector.

During development, the new components must be integrated into an overall concept for the facade. Effects on the total energy demand of the building, user comfort, reliability and long-term durability determine the economic viability and market potential of an innovation.

We optimise components and facades, drawing on our know-how and software tools, and test them in laboratory and outdoor test facilities. We evaluate the energy efficiency and develop adapted control strategies for dynamically changeable facades.

Coatings and microstructures are used to equip surfaces with special properties, e.g. infrared reflection, anti-reflective and self-cleaning effects. Switchable glazing adapts the visual contact and solar control according to the users' wishes.
