It’s no secret that lighting is a big piece of the energy pie when it comes to facility management. By selecting sources and control strategies for the right applications, managers can reduce their energy consumption by over 50 percent and improve the overall quality of their building’s lighting.

There are four basic types of systems in use today for controlling the operation of building lighting systems. Occupancy sensors detect when people are using a space, and they switch on accordingly. Once activity stops, the sensor switches off the lights. With the use of timers, one of the original management systems is still efficient, and the system switches off any light that’s unintentionally left on. Bi-level switching, common in parking garages and stairwells, can switch off one circuit, or the other, And finally, daylight harvesting senses and monitors daylight and thus reduces the level of artificial light needed for a given space. Typically, this method can save up to 30 percent energy.

All these applications will reduce your energy consumption. It all starts with setting goals for your building and understanding which applications will serve you best.
