Johnson Supply Retrofit

“Improving the energy efficiency of the places where we work, play, and learn helps us save energy, save money, and fight global warming.
Commercial and industrial facilities account for half of all energy consumption in the U.S. at a cost of over $200 billion per year. Nordco, Inc. is helping Johnson Supply to decrease their share of this number by upgrading present lighting systems to more energy efficient systems. In just upgrading its corporate offices, Johnson Supply reduces annual costs of energy operation by close to $30,000”.
