The Newport News Public School District located in Virginia has installed 185 Cree solid-state lighting (SSL) fixtures in an outdoor-lighting application at seven district schools. The LED-based lighting was used to replace 189 high-pressure sodium (HPS) and 150 incandescent fixtures.
The school district projects 65% savings in annual energy costs associated with lighting at the seven schools. The energy reduction is projected at 139,000 kWh annually equating to a reduction of 191,000 pounds of carbon emissions.
District officials expect payback on the project to come in three years with operational savings continuing for many more years. "These energy-efficient lights virtually eliminate maintenance, provide the district with dramatic energy savings and also reflect the community’s commitment to sustainability," said Keith Webb, executive director of plant services for the Newport News Public School District. "The LED lighting furthers our goal of enhancing and bettering the learning environment, while saving money for the schools and tax payers."
The district selected Cree's The Edge SSL luminaire family for the project. The Edge series includes products for security, parking, and area lighting in a variety of styles and form factors.
Schools that received the retrofits include General Stanford Elementary, Greenwood Elementary, Lee Hall Elementary, Palmer Elementary, Crittenden Middle, Booker T. Washington Middle, and Denbigh High. The new lighting provides enhanced uniformity and color quality in exterior corridors, walkways, and entryways.
