Building owners and facility managers are becoming increasingly aware of the cost savings and reduced energy consumption benefits of lighting control technology, including occupancy sensors that are most effective where there is constant traffic, timed switches based on elapsed time or programmed according to specific schedules, dimming controls, daylight harvesting, or a combination of these options.

Only 1 percent of buildings using controls, this is often one of the most overlooked, yet most effective, technologies in saving energy through lighting. Upgrading to lighting controls can save as much as 50 percent of the energy used in commercial buildings. 

Statistics from the National Electrical Manufacturers Association estimate the use of lighting controls can reduce energy costs by an additional 15 to 80 percent, depending on the facility, over and above savings from other lighting upgrades alone.
