Solartes Profile

Solartes is developing a unique smart material that harvests and stores solar energy during the day and releases the energy as heat during the night. Integrated into the building skin, the Solartes material could reduce the need for heating and cooling and potentially cut down energy consumption and emissions of buildings.

Solartes Pilot Story

VELUX and Solartes explored the endless possibilities that smart molecules offer – in this case, harvesting and storing solar energy during the day and releasing as heat after sunset. By delaying the heat of the morning sun to the cool evening, the Solartes material could drastically improve VELUX’s window insulation – increasing comfort whilst cutting energy consumption as well as the lifetime emissions of buildings.

“On the one hand, it is about showing what our technology can do and what it would bring to society and the development of sustainable buildings; on the other hand, it is very much about creating a network and finding partnerships that last even after the program.” – Anna Hofmann, CEO of Solartes
