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.

Customer's description

Das Viersternehotel Marietta ist sonnig und zentral gelegen. Die Skipisten und Langlaufloipen umgeben das Hotel. Die technische Ausrüstung des Hotels wird stetig an die bedürfnisse angepasst. Ein wichtiger bestandteil war die erneuerung der Regelung für Heizung und Warmwasser. Es wurden kommunikative KNX Heizungs- und Lüftungsregler verbaut und in das gesammtsystem integriert. Dadurch wurden erhebliche kosten für die Heizung, Belüfung und Warmwasserbereitung eingespart. Das Gesammte hotel wird in einem "Automatic" Modus betrieben und passt sich weitgehend an die belegung der Zimmer und nutzunf der Resaurants und Bar´s selbständig an. Alle Funktionen wie z.B Heizung, Lüftung Des gesammte Spaa bereich werden Viualisert, die vorhanden Kammera´s der Videoüberwachung wird ebenso angezeit wie der Energieverbrauch. Eine Maximumüberwachung sorg bei vollauslastung de sHotels dafür das der Energiverbrauch nicht zu hoch wird.
