Whitehall Schools wanted to upgrade interior lighting throughout the district to an energy efficient lighting system. The district had planned to greatly improve annual energy savings while simultaneously increasing overall performance with a simple payback under 10 years. Johnson Controls, the chosen partner for the overall project, called on Energy Performance LIghting to handle the district's lighting upgrades. Prior to installing an energy efficient system, Whitehall schools' lighting consisted mainly of 2', 3' and 4' linear fluorescent lamps and ballasts.
The project advisors at Energy Performance Lighting proposed energy efficient lighting designs with "good, better, best" options to meet the budget requirements of the district. To save on maintenance and product, the existing lighting system was calculated at three-quarter life remaining. To help conserve energy and reduce material and maintenance costs, efficient lighting designs by EPL included de-lamping fixtures to meet IES Recommended Practice, where appropriate. Fluorescent lamps and ballasts were upgraded with new Philips LED lamps and instant-start ballasts, while incandescent, compact fluorescent, and quartz lamps were upgraded with comparable LED lamps. EPL also upgraded recessed cans using pin-based fluorescent lamps with screw-based LED lamps, a conversion kit, and a transformer, as needed.
