1. Client Challenge:

The Dirksen Federal Building, with an aging lighting system, had a need for an updated lighting plan to incorporate dimming capabilities and networked controls for their courtrooms and classrooms on the 14th floor. This encompassed over 28,500 sq. ft. of space.

RTS performed an audit of the 14th floor of the federal building. RTS evaluated vast numbers of variables such as how the space will be used, amount of day-light, load potential, dimming, lamp color, initial cost, and cost to maintain moving forward.

2. Lighting Solution:

Retro-Tech performed a lighting upgrade within the Dirksen Federal Building. This $400,000+ lighting project was performed in order to provide new dimming luminaries and control systems for courtrooms and classrooms. The upgrade included new dimming compact fluorescent cans, dimming fluorescents, and dimming metal halide luminaries. In addition, an extensive Payne-Sparkman Controller was installed along with a computer network which provided touch screen controls at various points in the courtrooms.

3. The Results:

The overall results are impressive. The lighting system is now fully dimmable in multiple stages and each judge has complete control over all of the courtroom lighting.
