Lighting System

Lighting energy conservation offers major savings in almost any facility. In public buildings lighting typically accounts for 30% to 80% of total energy consumption. Lamps act as electric space heaters, so lighting energy conservation may substantially reduce air conditioning costs.

Day to day activities

  • Lighting fixtures

Recommendations, advice and tips

  • Advise occupants to switch off lighting if not needed instead of leaving lighting
    on all day
  • Major energy savings can be achieved from lighting since lighting accounts up to 40% of electricity used in non-residential buildings
  • By investing in an energy-efficient lighting system, between 30% and 80% of electricity used for lighting could be saved
  • Make sure that light bulbs installed are rated Class A
  • Use compact fluorescent lamps with electronic gears. They are more expensive, but can use 75% less electricity and last years longer. Pay back is usually achieved between less than one year and up to three years
  • In larger rooms, lighting should be made separately switchable for different zones (i.e. window and wall sides)
  • Lighting for bathrooms, toilets, or dressing rooms have to be motion controlled
  • Exterior lighting must be controlled via light sensors, timers, and maybe in combination with motion sensors, for security reasons
  • The motion sensor keeps the lights on as long as there is movement. After motion has stopped (time lapse is adjustable), the detector switches the lights off
  • With timers, you can save energy and control your interior or exterior lighting, or even appliances, by turning them on and off at determined times. Most modern timers are digital, easy to operate, affordable and can be programmed from 24 hours to 7 days and according to seasonal daylight schedules
