With a smart fa?ade, your building enjoys smart ventilation. With networked solutions, you can create a consistently good indoor climate, increase the ease of use and save energy. "Intelligent" is a fa?ade as a part of a smart building. The necessary functions and operating statuses are facilitated by the control unit and the interaction of drives, sensors and safety technology. Interface modules for the BACnet and KNX communication standards ensure dialogue between window ventilation systems, even in glass fa?ades.
