Tips for Energy Efficiency

- Turn off lights (and other equipment) when not in use. High utility costs often include paying for energy that is completely wasted.
- Install switch plate occupancy sensors in proper locations to automatically turn off lighting when no one is present and back on when people return. Even good equipment can be installed wrong, so don’t install the sensor behind a coat rack, door, bookcase, etc. It must be able to “see” an approaching person’s motion to turn on the light before or as they enter an unlit area.
- Adjust lighting to your actual needs; use free “daylight” during the day.
- To prevent glare, eyestrain and headaches, do not “over-light.” Too much light can be as bad for visual quality as too little light – and it costs a lot more.
- Install ENERGY STAR qualified exit signs. These exit signs can dramatically reduce maintenance by eliminating lamp replacement, and can save up to $10 dollars per sign annually in electricity costs while preventing up to 500 pounds of greenhouse gas emissions.
- Consider upgrading to T8 (1″ diameter) fluorescent lamp tubes with solid-state electronic ballasts that are more efficient than older T12 (1.5″ diameter) tubes with magnetic ballasts.
