An electronically ballasted lighting control system that was demonstrated at an office building is described. The system demonstrated the energy savings and demand reduction capabilities of a lighting control system designed to exploit all major control strategies, including scheduling, daylighting and lumen maintenance. After nine months of operation, lighting energy savings of approximately 50% relative to previous usage have been consistently achieved. A two-part control photocell, shown to be effective at maintaining light levels at the workplane regardless of the daylight contribution, is presented.
