Shelby County Government of Tennessee

Customer Profile:

The Shelby County Government of Tennessee serves over 867,000 citizens with their public resources. These public resources consist of The Criminal Justice Center, The Health Department, The Juvenile Justice Center, and Oakville Health Center.

Customer Issues:

• Increased Energy and Maintenance Cost
• Older Lighting Technologies
• Ensuring Quality Lighting
• High Number of Burned Out Lamps and Ballasts
• Lack of manpower to change out lamps and ballasts.

Project Objective:

As part of a comprehensive energy project, we conducted an energy efficient lighting upgrade at the Shelby County Government locations. The upgrade was designed to improve the working environment, replace old lighting technologies, reduce maintenance and utility costs, and standardize lighting materials. Light levels were evaluated at each site to ensure the areas met the Illuminating Engineering Society of North America (IESNA) lighting standards. The overall project was funded utilizing the reduction of energy dollars from within the existing utility budget.

Results:

Improved lighting systems and reduced utility cost were achieved by retrofitting the existing lighting system, which consisted of T12 fluorescent lamps and magnetic ballasts with new energy efficient T-8 fluorescent lamp and electronic ballast technologies. The project resulted in many benefits for the various locations that included reduced energy costs, reduced operating costs, and standardization of lighting materials. Improved lighting, funded with reduced energy cost, extended the life of lamps and ballasts, increased maintenance productivity, and protracted material warranties.
