Abstract
Many types of lighting control equipment permit the automatic management of lighting systems. Lighting control equipment can be used to lower light levels, turn lights on and off on a schedule, and respond to the availability of natural light or the presence of occupants. Each of these operations minimizes the energy consumed while providing the proper illumination for occupants’ use of the space.
The choice of lighting control system depends on its particular application (retrofit, renovation, or new construction). This presentation will attempt to provide a basis for selecting the control equipment and the control strategies (light reduction, scheduling, tuning, lumen depreciation, daylighting, load-shedding) most apropos to an application, and presenting the important cost factors (initial, operating, installation, supply circuit layout, building design) that one must consider for each application.
