Lighting action items:

  • Turn off task lights when leaving your desk for lunch, or any lengthy period of time.
  • Make sure the lights are turned off when you leave conference rooms, break rooms, restrooms, etc.
  • Create signs that empower employees and remind them to turn off lights.
  • Regularly clean lamps and reflectors to prevent dust accumulation and light level loss.
  • Regularly inspect light fixtures and replace those that buzz, flicker, cause excess glare, etc. (and remember to recycle your bulbs).
  • Clean windows regularly to maintain maximum daylight transmission.
  • Adjust lighting levels according to need, rather than applying uniform levels throughout the building.
  • Replace exit signs that have incandescent lamps with light-emitting diode (LED) models.
  • Replace incandescent and HID lamps with high-efficiency fluorescent (T5 or T8) and compact-fluorescent (CF) lamps. 
  • Replace any magnetic ballasts with high-efficiency electronic ballasts.  Note: older ballasts may contain PCBs and must be disposed of properly as a hazardous material.
  • Sunlight does not cost anything to consume, and is generally abundant during the day. It has also been shown that employees receiving abundant natural light are more productive at work.
