California State University, Channel Islands
Tier2-2: Lighting Sensors

California State University Channel Islands (CI) has two evaluation programs in place for interior and exterior lighting control. Some classrooms, offices, and hallways have lights that are equipped with an occupancy sensor to turn off lights when the space is unoccupied. In addition, spaces that provide sufficient daylight, photosensors, were installed to turn off lights when daylight provided sufficient levels of light. Renovated buildings are also equipped with lighting control systems. The lighting control panels are networked to a lighting control server, which provides the campus control over all lights connected within the network. The lighting control panels communicate with the campus energy management system, in which, provide the lighting control panels with a signal to change to a new control program tailored for an energy demand response. Exterior lights are powered through relay panels, which are controlled by photosensors and astronomic time clocks. The new exterior light panels are able to communicate with the campus energy management as well. Luminaries are connect to staggered circuits, giving the campus the option to reduce lighting levels and energy used during periods of low activity, while still maintain uniform lighting throughout a given area.
