• Installation of high frequency luminaires. This modern type of luminaire can be up to 30% more efficient than the older type of fluorescent Luminaire.
  A further benefit of this type of luminaire is that the frequency of light change is so fast it is more comfortable on the eyes making for a more pleasant work environment.
  
  
• High frequency luminaires can be used with day light automatic dimming.
  A light sensor automatically adjusts the light output level to allow for day light in a room. In a bright day light room, the luminaires will drop down to below 30 % output, making great saving on electricity bills. This method is very simple and requires no action from the building users but saves on electricity all year round.
  
  
• Installing Presence sensors to rooms. With this method lights are only on Monday, April 16, 2007 to large savings on energy bills. Combined with modern luminaires described above and day light dimming, very large savings can be made(approximately 40-50 %).
  
  
• Replacing any old Tungsten luminaires with fluorescent type luminaires. A fluorescent luminaire uses about a quarter of the electricity of a equivalent Tungsten type lamp.
  
  
• Installation of lighting control systems to large buildings.
  This type of system can give the landlord great control over the way lighting is used in a building. Lighting can be timed to come on and go off at certain times and be adjusted Monday, April 16, 2007 of the building users. The down side of complex systems is that they can be expensive to repair or change.
  
  
• Thermostatic control of any electric heaters or operation by presence detectors/time switches.
  This can help minimize wasted expensive use of electric heating. Generally heating by electric heaters is not cheap(unless by Economy of Peak storage Heating). Large bills can be run up quickly with bad controls on electric heaters.
