The Green Proving Ground program has commissioned Department of Energy National Laboratories to perform real-world measurement and verification of the following technologies in pilot installations in federally-owned buildings. Preliminary technology assessments are available below as PDFs.
Preliminary Technology Assessments
LED Lighting with Integrated Controls > This lighting technology integrates the LED lamp, driver, daylight controls, and occupancy sensors into a single fixture for easy one-for-one replacement of the existing luminaires. Auto-calibration of daylight sensors and use of a handheld remote to group fixtures promises to overcome a key hurdle to realizing lighting energy and cost savings: the effective integration and commissioning of controls. The luminaire builds on the inherently dimmable nature of LED lighting by integrating occupancy and daylighting controls directly into the fixture and its driver. Findings available in 2015.
LED Retrofit Luminaire > This technology is designed to upgrade existing recessed fluorescent troffer luminaires to LED luminaires. Findings available in 2015.
Wireless Lighting Control System > This technology enables switches, ballasts, fixtures, and sensors from a variety of manufacturers to communicate as a single system by using wireless area controllers. The technology enables building operators to tailor lighting control to building characteristics and occupancy patterns more easily and cost effectively than incumbent technologies offering similar levels of control. Findings available in 2015.
Wireless Lighting Controls > The wireless lighting control system represents an innovative private sector application of a wireless mesh network communication protocol developed by the Defense Advanced Research Projects Agency (DARPA). It leverages low cost radios developed for the cell phone industry and recent advances in powering devices using scavenged power. A small wireless module mounted on the inside of an existing light fixture communicates with other wireless modules, self-powered switches, photovoltaic-powered daylight and infrared sensors, and a facility automation server to create a low-power wireless control network throughout the commissioned work area. Findings available in 2015.
