Reduction of Lighting Energy Consumption by 25% Site Wide

Abstract

The lighting energy consumption is typically overlooked at Department of Defense facilities because, if it works and provides sufficient lighting, no one complains. The key to achieving energy savings through lighting, is to follow Illuminating Engineering Society Standard on luminance. The causes for energy waste, are utilizing old lighting technologies as Metal Halide and lack of controls. In an effort to reduce energy consumption at one site in Fort Gordon Georgia, the implementation of Light Emitting Diodes was researched. It was found that the lighting energy consumption could be reduced by 37% by just changing the light fixtures. An additional energy saving between 43% and 50% could be achieved by adding lighting controls such as motion sensors and photosensors. All the phases of improvement listed in this paper can be implemented in a phase approach to limit impact to site personnel and to allow budget planning.
