John J. Duncan Federal Building (Knoxville, TN)

General Services Administration

In FY 2004, a project to replace an outdated energy management system at the John J. Duncan Federal Building allowed GSA to reduce energy use and operating costs while creating a healthier work environment for building occupants. Along with the new energy management system, the project incorporated high efficiency lighting, variable frequency drives, a new cooling tower, high efficiency motors, and motion sensors, resulting in savings of almost 225 megawatt-hours annually. Restrooms were retrofitted with water-saving equipment, and new secondary meters were placed on water supplies to reduce water sewage and runoff charges, saving 668,000 gallons of water each year. These and other environmentally friendly practices have resulted in an ENERGY STAR® rating of 94 and a Leadership in Energy and Environmental Design (LEED™) certification nomination.
