With more than 40,000 parking spaces to light Cox Enterprises, owner of Manheim Pennsylvania Auto Auction, the world’s largest auto auction carries a sizable electric load. The lot achieved 50% outdoor lighting energy savings through a retrofit of outdoor lighting—totaling 1.8 million kWh in annual savings over the 13.5 million square foot facility.
Cox’s Lighting in Energy Efficiency in Parking (LEEP) Campaign Award winning project retrofitted high-wattage metal halide fixtures with reduced- wattage pulse-start metal halide lamps and a wireless control system. The controls enable further energy savings by allowing fixtures to be turned off when not needed. In addition to the energy savings, the longer rated life of the new lamps also reduces maintenance costs. The significant energy saving from the new fixtures and lighting controls resulted in a simple payback period of less than 4 years.
