 Adura Technologies designs and manufactures wireless lighting controls. The heart of our system is a wireless transceiver and microprocessor, or "mote". These devices make up an intercommunicating network, often referred to as a mesh network. The light fixture control unit which is installed inside a fluorescent light fixture consists of a mote and a relay. Since each mote acts as a separate, independent sensing and signaling point, it is possible to both receive remote information and send information to remote locations across the network without wiring. This allows the system to receive local control signals from a control unit nearby as well as signals from a central control station. The system is tied together by software that interprets signals from the network and sends commands to the proper controller. Our system can have any number of control methods including motion sensors, remote controls, wall switches, and personal computer desktop operability. Our technology was developed at the University of California by the Center for the Built Environment (CBE). An 8 fixture demonstration project was installed in Wurster Hall in CBE office space. The system design used a hand-operated remote control that was shared by the occupants of the office. Monitored data showed a 40% reduction in lighting energy use and high user satisfaction. Currently CBE has a $75,000 grant from the California Energy Commission to further develop the technology. This money will in part fund a larger demonstration project in a 10,000 square foot office space within the University of California during the summer of 2005. |
