Lighting
- Turn off lights (and other equipment) when not in use.
- Install occupancy sensor switches in seldom-occupied areas like closets, storage areas, and conference rooms- any area/room where people may forget to turn out the lights.
- Adjust lighting levels to match needs. Remove un-needed lamps, ballasts, and/or fixtures. Check current lighting levels against IES recommended levels. Use lower levels of general lighting and more task lighting to directly illuminate work areas and reduce computer screen glare.
- Make use of free day lighting, where possible. Turn off or dim lights when day lighting is available, or use automatic dimming controls. Use high reflectance ceiling tiles and light colors on walls, partitions, and carpeting to carry daylight into interior space.
- Replace incandescent bulbs with compact fluorescents (CFLs) wherever possible. CFLs only use only about half the energy, plus, they last 10-12 times as long, saving on replacement bulb cost and labor.
- Replace incandescent and fluorescent exit signs with light emitting diodes (LEDs) or the latest solid-state technology. LEDs exit signs use about 1/10th the energy of an incandescent bulb. Plus they can last for 100,000 hours!
- Schedule cleaning services during the day. If you must clean the building at night, use the minimum number of lights, only as needed.
- Replace T-12 fluorescent fixtures with energy saving T-8 fixtures and electronic ballasts. Design the new system for the lighting level needed for the building use, using IES standards. Use parabolic reflectors to reduce glare. Supplement with task lighting.
- Install controls on exterior lighting. Install motion sensors, time clocks, or photoelectric sensors on exterior parking lots and security lighting.
