Saving Energy at Work: Lighting

[Picture] [Picture][Picture]

Lighting is one of the major consumers of electricity in University buildings.

Modern lighting technology includes developments in:
• low energy lights - less power, more light
• luminaire design - directing the light where it is needed
• lighting controls - light areas only as needed and as much as needed

At home using low energy lights is one of the best ways of saving energy. They cost more than conventional tungsten filament bulbs but last 8 times longer and use only one quarter of the electricity, paying for themselves many times over during their lifetime.

[*]Ways you can help
• switch off lights that are not needed
• make maximum use of daylight
• don't leave lights on in unoccupied areas
• reduce decorative lighting where possible
• ensure that someone switches off lights after hours
• don't switch on all the lights when only a few are needed
• fit labels on switches so people know which operate particular lights
• use desk lights if few people are in the room

[Picture]"Fluorescent lights use so much power to start up, isn't it best to keep them on all day?" No, it's a myth! Start-up electricity use is equivalent to a few seconds of normal running. Switch off the lights you don't need and the savings start immediately.
