Building integration

Solar building envelopes – energy generation with architectural value

At ISFH, we research innovative concepts for the integration of solar thermal, photovoltaic, and combined photovoltaic-thermal (PVT) technologies into buildings. These concepts aim to meet functional, economic, and design requirements. Solar-active façades and roofs are intended not only to generate energy close to the point of use (e.g. heating devices) but also to integrate harmoniously into the architecture and provide additional functions.

One focus at ISFH is the thermal activation of the building envelope through suitable heat transfer solutions. The goal is to enhance system and cost efficiency as well as aesthetics by leveraging constructive synergies – especially in combination with heat pumps.

At the same time, the Photovoltaics special module production research group develops customized PV modules for building-integrated applications. Close collaboration between module development and the system technology groups ensures that new PV modules are not only designed for integration into buildings but are also assessed as part of the building’s overall energy system.

Building-integrated solar technology at ISFH combines architectural freedom with technological efficiency, whether for new buildings, renovations, residential or non-residential structures. Together, we design building envelopes that generate energy, enhance architectural quality, and contribute to the decarbonization of the heating sector.
