Lighting can be turned on, off, or dimmed with a building automation or lighting control system based on time of day, or on occupancy sensor, photosensors and timers. One typical example is to turn the lights in a space on for a half hour since the last motion was sensed. A photocell placed outside a building can sense darkness, and the time of day, and modulate lights in outer offices and the parking lot.
Commercial lighting control automation can harness the energy saving power of automatic dimming, daylight harvesting, load shedding and demand response.
Lighting is also a good candidate for demand response, with many control systems providing the ability to dim (or turn off) lights to take advantage of DR incentives and savings. If occupancy sensors are present they can also be used as burglar alarms.
Lighting systems, both inside and outside, can be set to a schedule so in unoccupied hours minimal lighting is on. Motion sensors can also be hooked up to DDC and monitored for usage. Programs can be set up to bill tenants for energy use for lighting and other energy consuming systems.
