Lighting tips for the office environment

  1. 1. Replace incandescent lamps by CFLs in rooms where light is required for long periods of time. The CFLs use 50 to 80% less energy and last up to eight times longer compared to incandescent bulbs. The CFLs should, however, not be installed in areas where brief illumination is required because frequent switching will shorten the life of the lamp.

  1. Lights usually need not be on all the time, turn them off when not needed.
  2. If necessary, reconfigure the office layout so as to make the best use of daylight.

  1. Use task lightning instead of brightly illuminating an entire area. For example, use desk lamps.
  2. While taking care not to sacrifice visual comfort; use the lowest wattage possible to light up an area.
  3. Remember to keep lights and fittings clean. The presence of dirt on a lamp can greatly reduce its light output.
  4. Place switches at rooms exits so that people get the habit of turning off lights when they leave. Also, strategically locate two-way switches in corridors and stair-cases.

  1. Avoid having several lights activated by one switch – use separate switches for each light.
  2. Choose light colors for walls, ceilings and curtains. Dark colors absorb more light and hence increase the amount of lightning needed.
  3. Equip rooms with occupancy sensors which switch off lights a short while after people leave the area.
