Philips Lighting carried out a full survey of the Department of Chemistry building and recommended that all T12 and T8 fluorescent fittings were replaced on a point-for-point basis with LED luminaires, many of which are dimmable.
PowerBalance LED luminaires have been installed in offices and small laboratory areas, with suspended SmartForm LED luminaires in larger laboratories and ceiling-mounted SmartForm in stairways and landings. Both ceiling-mounted and wall-mounted Gondola LED luminaires have also been used in stairways. GreenSpace recessed downlighters are providing low energy lighting in corridors and meeting areas on each floor.
Switching to dimmable LED luminaires also means increased controllability and further energy savings beyond those achieved by reducing the installed load alone.
