JC Penney: Variable Frequency Drive Retrofit Upgrade on Rooftop Units (RTUs)

In order to streamline efforts for eliminating inefficiencies, JC Penney, a major apparel and home furnishing retailer with approximately 1,020 locations throughout the United States, pursued a pilot program for RTU variable frequency drive (VFD) technology. Following the successful pilot program, JC Penney retrofitted 1,330 rooftop units in 130 additional stores with the VFD retrofit solution. The company recognized savings of as much as 47,800,000 kWh, a 22% reduction from before the VFD retrofit and a monetary savings of as much as $5 million.
