Lighting designs for supermarket applications
Designers of lighting systems for supermarket applications face a number of challenges when the goals are to present merchandise in an attractive environment, but to do so in an energy-efficient manner. The Defense Commissary Agency (DeCA) operates several hundred stores worldwide, and more than 150 within the United States. DeCA is a federal agency that was organized in 1991 to operate commissaries that had previously been operated by the various armed services. As a federal agency, DeCA is also under a federal executive order to reduce its total energy consumption per square foot of floor space by 20 percent by the year 2005, compared to energy use in the year 1990. On the average, lighting consumes more than 20 percent of a store`s total energy use. Lighting retrofit projects offer opportunities to save significant energy costs with reasonable cost payback. The variety of ages and architectural styles of the commissaries offer opportunities for analysis and design of a wide diversity of projects. These projects range from simple replacements of lamps and ballasts to luminaire replacements and complete redesign of systems, including circuits. The requirements of merchandising products (illumination) also affect system designs. Several types of lighting retrofit projects are discussed. Problems that were encountered and solutions that were developed are shown. Because commissaries are supermarkets, lighting system designs are applicable to commercial establishments.
