Smart shading with KNX

Well-designed shading is crucial for energy efficiency and comfort – especially in modern, well-insulated buildings. With a KNX-controlled solution, solar radiation can be automatically regulated: in summer, it prevents overheating, while in winter, it uses solar heat to reduce heating costs. Thanks to smart sensors and automation, the system adjusts to weather conditions in real time – without any manual intervention. Find out how you can optimise your shading system and save energy sustainably with KNX!
