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

Innovation

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

Lighting: Switching , Dimming , Constant Light Control
Heating, Ventilation & Air conditioning (HVAC): Individual Room Control / Zone Control , Floor Heating Control
Blind and Shutter Control: Individual Control , Group & Central Control , Wind and Rain Protection , Sun Tracing (interaction with HVAC / lighting)
Operation and Visualisation: Touch Panels & Display Panels
Automation and Remote Access: System Supervision , Remote Programming

Customer's description

Ziel der KNX Installation ist es die Kosten des Gebäudes einzusparen. Deswegen wurde entschieden, die komplette DALI-Beleuchtung anhand von Präsenzmeldern zu steuern. Speziell in Klassenzimmern kommt die Konstantlichregelung zum tragen - dabei wurden spezielle KNX Präsenzmelder in Lampen verbaut. Die Jalousien, die nur auf der Südseite vorhanden sind, werden nicht nur mit den RTR-Multi-Touch Pro von Schneider Electric geregelt, sonder auch über die Wetterstation. Dabei werden die Lamellen der Jalousien bei Sonneneinstrahlung nachgeführt. Außerdem werden in allen Räumlichkeiten, in den eine Fußbodenheizung vorhanden ist, die Temperaturen anhand von RTR-s geregelt. Für Mögliche Fernwartungen haben wir einen KNX/IP-Router eingesetzt.
