Duncan Federal Building


Knoxville, TN

Over 15 years ago, we constructed this new federal courthouse for the US General Services Administration (GSA) in downtown Knoxville.  Due to its status as a major government facility, the design and construction of this building utilized significant energy-saving and sustainable features, although at that time, the idea of “green” and sustainable design and construction were in their infancy.

In 2006, the GSA made modifications to the building to add additional sustainable features.  These changes included replacing the plumbing fixtures to create water-saving features, and replacing the light fixtures to incorporate more energy-conservation features.  As a result of these modifications, the building received LEED certification in February, 2007, making it the second existing building certified in the USA.
