Lighting Controls

Install controls on exterior and interior lights to turn them off when not required. Emergency and security lighting excluded. I work at DOE HQ and have noticed many exterior lights operating during daylight hours when they are clearly not needed since sufficient daylight exists. Photo-controls, occupancy and vacancy sensors can be installed to extinguish these lights when sufficient ambient light or occupany exists. As a former energy auditor, this was one of the easiest and most cost effective energy conservation measures that we recommended to building owners. This opportunity exists for buildings belonging to all Federal agencies, regardless of building age.
