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

  • Lighting: Switching , Dimming , Light Scenes , Timed Control , Automatic Occupancy Detection
  • Heating, Ventilation & Air conditioning (HVAC): Central & Automatic Control , Timed Operation Modes , Automatic Occupancy Detection , Valve Drive Control / Fan Coil Control , CO2 / Humidity Measuring
  • Security and Safety: Smoke/Fire Detection , Faults (e.g. Leak Detection, Glass Break Detection, Window Contacts) , Access Control , Intrusion Detection / Alarm Systems , Emergency Lighting , Presence Simulation , Supervision (e.g. Cameras) , Interaction with HVAC/Lighting
  • Operation and Visualisation: Switches / Push Buttons , PC Visualisation
  • Automation and Remote Access: Timed Functions , Logical Functions , System Supervision , Internet Access , Remote Programming , Messaging (e.g. SMS)
  • Energy Management/Smart Metering: Metering , Current Detection , Energy Harvesting (Avoiding use of batteries) , Battery Storage

Customer's description

Each metro line about 25 stations, it over 10000m2, thouands of KNX devices, because full line is long long way(about 200km), KNX communication is very important, and must find a new way to intergrate KNX into Metro system. Devices & Functions are: KNX switch, KNX touch panel, scenes, timmer, current measurement, DALI control, brightness & motion, center control... After our Guangzhou No.13, No.14, No.21 metro station finished. We can see that KNX system is easy and good to intergrate with metro managerment system. KNX project not only good in Airport, but also in metro station. There are so many metro stations from different cities asking us for solution. It help us to win many metro projects. Now KNX metro transportant is the big market we can do.
