3rd Annual Flex Your Power Awards
Lawrence Berkeley National Laboratory
Recognized for the research and testing of a motion-sensing wall switch in hotel bathrooms, Lawrence Berkeley National Laboratory, in partnership with Doubletree Hotels, Sacramento Municipal Utility District and the Watt Stopper, tested the Watt Stopper's motion-sensing wall switch. The switch, which controls lighting based on occupancy, is integrated with a nightlight that remains on when the motion-sensor turns the lights off. Lawrence Berkeley National Laboratories analyzed data from a 400-room hotel installation and determined that average energy savings were 47%.
