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 , Automatic Occupancy Detection , Constant Light Control
  • Security and Safety: Emergency Lighting

Customer's description

Nelle 17 stazioni della nuova linea della metropolitana sono stati installati apparecchi illuminanti con reattori DALI. Il committente ha richiesto il controllo di luminosità costante nelle zone di ingresso (dove vi è apporto di luce naturale), negli altri ambienti il comando avviene con livelli dipendenti dall'ora del giorno per meglio gestire il passaggio dalla luce esterna a quella interna. Nei locali chiusi (come i depositi delle biciclette) i sensori di presenza permettono la gestione dell'illuminazione in base all'effettivo utilizzo dei locali stessi. In caso di emergenza l'illuminazione viene gestita dal sistema DALI alimentato da UPS. Il tutto è in collegamento con la supervisione centrale tramite protocollo modbus.
