Energy consumed by the electrical lighting system can be saved by installing better light emitting technology,
better control systems (occupancy and daylight dependent dimming) and a possibility for a control of the light
depending on the location within the room near the windows or far from the windows so-called zoning. Often
this is done as one package as the marginal costs for including the control and zoning is rather limited when a new
lighting system is installed. In the calculations a complete package is therefore analysed.
The efficient lighting systems considered are new light tubes T5, compact fluorescent light (CFL) and LED lamps.
Controls are manual, continuous dimming and 2 zones versus one in the reference case have been analysed.
