In open plan office areas 600 x 600 fluorescent fixtures have been replaced with Philips PowerBalance recessed modular luminaires, while LuxSpace downlighters have been used in and around the reception area as well as in meeting rooms. Other fixtures included CoreLine and LED Amenity in toilets and the main staircase. Existing fittings in the communications room, switch rooms and cleaners’ stores have been retained and upgraded with MASTER LED lamps. The new lighting system is controlled through a LightMaster lighting management system which provides comprehensive information on the performance of the system, accessible from a central location.
The lighting control strategy includes daylight linking at the perimeters of the building and occupancy detection within the open plan spaces.
