1. Replace standard
incandescent with
reduced wattage
|
- Replace standard wattage lamps with energy saving reduced-wattage lamps with about the same light output.
- For example, replace a standard 100 Watt with an energy savings 90 Watt lamp.

2. Replace standard incandescent with
Halogen
|
- Halogen lamps are about twice as efficient as standard incandescent lamps. With their brighter, more focused light, you can replace a high wattage incandescent with a low wattage halogen.
- For example, replace a 150 Watt standard incandescent with a 30 to 60 Watt halogen.

3. Replace incandescent with compact
fluorescent
|
- Compact fluorescent lamps and fixtures use about a quarter of the energy of incandescents.
- For example, replace a standard 75 Watt downlight with a CFL that uses only about 20 Watts.
- If you are constructing a new building or doing a major renovation of an existing one, use recessed fixtures with dedicated CFLs.

4. Fluorescent lamp replacement or removal
|
- Many older buildings are significantly over lighted. In some cases you can remove lamps and disconnect ballasts and still have excellent light quality. In other cases, simply replacing standard wattage lamps with energy saving lamps can be an effective savings measure

5. Replace magnetic ballasts with electronic
|
- Replace old, inefficient magnetic ballasts with new, high-efficiency electronic ballasts.
- Often this process includes retrofitting fixtures with high-efficiency T-8 lamps.

|
6. Replace incandescent exit signs with CFL or LED
|
- Incandescent exit signs consume about 40 Watts while CFL signs consume only about seven Watts and LED signs only about one Watt.
- Exit signs operate 24 hours-per-day, 365 days-per-year. With year-round operation and the numerous signs that exist in many buildings, significant savings can be achieved.

7. Install occupancy sensors
|
- Many spaces such as individual offices, conference rooms, storage areas and rest rooms are unoccupied during large portions of the day.
- Occupancy sensors that detect the presence of people and turn lights off during unoccupied periods can result in lighting energy cost savings of 25 to 75 percent.
|
|
------------------------------------------------------------------------------------------------------------
|
|
8. Install daylighting controls
|
- Use daylighting controls to reduce lighting energy costs in perimeter areas of a building next to windows and in open bay areas with natural overhead light provided by skylights.
- Properly designed and installed, they can reduce energy use by 40 percent or more and are an excellent means of reducing peak loads on the building’s electric system.
