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

Dieses Einfamilienhaus wurde als Plusenergiegebäude konzipiert. Mit einer 17,84 kWp Photovoltaikanlage und einem Batteriespeicher werden ca. 70 % der Strommenge für die Wärmepumpenheizung, den Hausverbrauch und die Elektromobilität erzeugt. Die intelligente Verknüpfung und Visualisierung aller Komponenten erfolgt über die KNX-Steuerung. Bei modernen Gebäuden mit guter Dämmung ist der sommerliche Hitzeschutz besonders wichtig. Zu diesem Zweck steuert die Wetterstation abhängig von der Helligkeit und der Raumtemperatur die Beschattung mittels Jalousie. Sollte dies nicht ausreichend zum Einhalten der Wohlfühltemperatur sein, startet die Kühlungsfunktion der Wärmepumpe.
