A 7.5 kWp photovoltaic array is integra- ted into the saw-tooth roof of the atrium. Photo- voltaic modules with a total area of more than 200 m2 are integrated into roof and façade elements, and contribute to the electricity supply for the Institute. The energy concept for the buil- ding is based on energy conservation and rational use of energy (© Bernd Lammel, Berlin).

This start-up will produce materials. PCM has the capability to absorb heat from the solar-driven systems for water treatment and desalination and environment and to release it again when needed in order to bring them to the market. They concentrate on decentralised stabilize the room temperature. applications.
