At Wellsun, we believe that improving the energy performance of the building environment should be a great experience. Only then will people have the motivation to do what needs to be done. Only then can we accelerate and create the momentum that leads to change. Only then can we change the world.

​Wellsun has developed the Lumiduct which makes livable, transparent, and energy producing buildings become reality. The Lumiduct enables full glass facades which generate more energy than closed walls completely covered with traditional solar panels. The Lumiduct saves energy and creates an ideal indoor climate by selectively shielding the intense, direct light which is responsible for glare and heating up of the building, and turns it into electricity. At the same time, the Lumiduct is transparent for the soft, diffused light which is then experienced as pleasant daylight.

​With the Lumiduct, the building comes to life. During the day, the facade is activated by the brilliant transparent solar panels, enabling the building to generate and save energy. At night, the facade is activated by the integrated LEDs making it possible to create a beautiful atmosphere and communicate with the community. The Lumiduct creates awareness and makes living in and around the building a great experience.
