Lime Energy marks first phase done

ELK GROVE VILLAGE -- Lime Energy announced the completion of the first phase of an energy efficiency retrofit of a major airline's maintenance hangar at San Francisco International Airport. The project involved replacing nearly 500 lighting fixtures in offices and work areas as part of a lighting upgrade that will save operating costs and reduce greenhouse gas emissions. This project utilized sensors that automatically turn lights off when space is not in use or when there is enough sunlight to provide adequate natural lighting.
