Detailed description

Energy Efficiency

The usage of automated functions already save energy in every installation. Especially the usage of KNX has a lot of potential for further energy savings, which can contribute to a better environmental footprint. Be extending KNX to more functions and applications, energy savings of up to 60% can be realised. Thanks to the flexibility of KNX, these functions can easily be implemented in this installation


Smart homes and buildings are always an upgrade in comparison to a conventional installation. Not only automated functions and a higher level of comfort contribute to a higher living standard, but also the possibility to be ready for coming innovations. Thanks to the usage of KNX, the door has been opened to integrate new innovative solutions, using the worldwide STANDARD for home and building control.

Ease of Use

By integrating KNX, we automatically experience a higher energy efficiency and comfort. Furthermore, by the possibility to use further devices, in order to make the usage of the project easier, we can look at further opportunity to even make the whole installation easier in usage.

Applications used

Customer's description

A highly sophisticated KNX infrastructure capable of controlling literally everything in this apartment. DALI lighting with circadian features, shutters, blinds, shades and slats with sun trace control via the weather station, Heating, Cooling via A/C units, True presence through STEINEL high frequency detectors, measuring temp, hum, co2, VOC, and air pressure feeding lunos units with the correct data in order to boost their operation. Metering the electricity values with 8 basic characteristics such as power factor, voltage, ampere, frequency, reactive power, type of reactive power, power and apparent. Metering the water consumption and flux. Flood avoidance via water probes and digital inputs that cut off the water supply via electromagnetic valves. Security system and cameras integration with line crossing triggers.
