Abstract: Artificial lighting in office and school buildings is a major and conspicuous consumer of electricial energy. In addition, air conditioning consumes energy and may be required to remove the heat generated by lamps. Energy consumption is measured as the product of power input ( kilowatts) and the period of use (hours). To reduce it both input and hours of use must be controlled. Power input may be reduced by lowering general illumination levels, adopting selective lighting standards, and replacing inefficient sources. Hours of use can be reduced through sensible switching arrangements and automatic light control that takes advantage of available daylight and space occupancy.
