PHYSEE Technologies


We are a technology company from Delft, engineering smart solutions for the global energy transition. Our solutions aim to activate existing materials, for undiscovered, sustainable impact. Our mission started with activating a single window with solar functionality, however, our curiosity has continued into engineering new solutions for crop growth inside greenhouses, as well as efficient equipment that produces customizable solar for endless applications. Across all these solutions, we consistently aim to change the perspective on how current materials are used and implemented, as well as challenging the system innovation behind them. The future we envision is one with energy-neutral buildings, centred around human comfort, and filled with sustainable solutions that don't compromise on aesthetics or functionality. Our growing team of 40 PHYSEEonairs work on Research & Development, Production and Projects to ensure the future we envision.

"SmartSkin" comes from the concept of comparing the building envelope to the skin of your body, as they should both have the same function: use external factors to protect and improve internal functionality. Our SmartSkin facade uses natural daylight, air and temperature in order to improve the indoor climate of a building for its users, while also reducing the energy consumption of it. SmartSkin is made up of "SmartWindows" with integrated sun shading or air ventilation systems. Together, they act as a stand-alone system that takes care of a building. SmartWindows have frames with integrated sensors and solar cells, that allows dual functionality: (1) sensors collect humidity, temperature and lux data from external environments and communicate it to the sunblind or air systems, that accurately work with nature to improve indoor environments, reducing the unnecessary energy use of a facade. (2) the solar cells produce the energy for those systems to operate on, which reduces the entire energy consumption of the facade.
