Products: PCA EXCEL one4all
The colours of yellow and white are used for different effects in the training building run by the BFB (Bildung Formation Biel-Bienne). Dimmable PCA EXCEL one4all create a pleasant atmosphere in which to learn and offer economical operation.
The yellow world of the foyer, assembly hall, restaurant and connecting zones is exciting, almost opulent and suggests rest, relaxation, leisure time and fun. This impression is reinforced by the Olot pendant luminaires with their organic shape, round and conspicuous. The formal atmosphere in the white lit training and work rooms is emphasised by the large square Qatar semi-recessed luminaires.
The acrylic luminaire cover is mitred to highlight the precise nature of the luminaire. The six T5 21 W HE fluorescent lamps are operated on three digital dimmable PCA EXCEL one4all ballasts from Tridonic and controlled via DALI (Digital Addressable Lighting Interface). Task-specific lighting moods are preprogrammed in the training area for different activities.
The training and work rooms are lit with uniform glare-free light with an average illuminance of 500 lx to comply with relevant standards. The light emitted from the sides of the acrylic covers illuminates the ceiling to create a pleasant atmosphere. 254 luminaires with a total of 762 PCA EXCEL one4all units have been installed to produce a lighting solution that is in keeping with the architecture and at the same time innovative.
A business-like atmosphere
The entire lighting system in the BFB training building is controlled by a DALI system on the basis of available daylight, with the DALI system integrated in EIB/KNX building systems technology. This solution, based on two-lamp PCA EXCEL one4all ballasts, enables the shading and lighting system to be centrally displayed, monitored, logged and operated, offering enormous flexibility in dealing with changes of use for example. Visualisation software allows the entire building to be easily controlled via a PC and the internet.
The combination of DALI lighting control and EIB/KNX building systems technology provided by Bering AG Professionelles Elektro-engineering Berne, means that the energy consumption requirements for sustainable buildings are fully met. The Swiss energy consumption requirements call not only for maximum energy efficiency but also for economical solutions. The control commands for the lighting system for example are generated by the weather station mounted on the roof and by motion sensors. Users can manually override the preprogrammed scenes by just pressing a few buttons.
The architecture of the training building run by BFB (Bildung Formation Biel-Bienne) features an unusual internal layout. The lighting components used in the building, such as the digital dimmable PCA EXCEL one4all ballasts from Tridonic, ensure economical operation.
