Advanced Lighting Demonstration: Cree SmartCast
This demonstration is one in a series of advanced lighting demonstration projects completed through a joint initiative between the DesignLights Consortium and the U.S. Department of Energy.
The medical office facility located in Avon, Connecticut houses multiple healthcare providers in three stories of mixed-use space. The building owner chose the recently completed LED lighting and controls retrofit to harvest extra savings and to improve lighting quality and controls. The Cree SmartCast® technology, applied at the luminaire level, incorporates wireless controls which support one-for-one replacement. The new lighting system provides wireless communication with advanced sensor options that allow for customization of light levels to meet application and occupant needs. The replacement of older fluorescents with LEDs alone saved over 29% of the estimated annual lighting energy use at this site. Note that a significant portion of this is attributable to the reduction in light levels, correcting previously overlit areas in the building. With advanced occupancy sensing and daylighting controls, energy savings increased by an additional 33% for a total of 62% savings from baseline conditions.
