River Forest Schools


Project Background

Roosevelt Middle School in River Forest, IL faced the challenge of cost-effectively improving lighting in its primary gymnasium. 15 year-old 400 Watt Metal Halide fixtures showed their age by way of dark spots on the floor edges and corners, as well as a greenish glow from lamp color shift. Finally, rising lamp and ballast replacement costs made it clear that it was time for a lighting upgrade.

When the decision to upgrade was made, the 24 gymnasium light fixtures put out half the light required for athletic events/activity. Sven Dahlquist Architecture, a lighting design and consulting firm specializing in schools, researched the project and all available options, and determined the most cost-effective way to improve the gymnasium lighting to be a one-to-one replacement with 24 qty 165W Lumerica LED High Bay light fixtures. After installation the fixtures will reduce electricity demand by approximately 65% while almost doubling the amount of light.

This LED lighting project will save Roosevelt Middle School an estimated $62,500 over the next 12 years in energy and maintenance costs, and will pay for itself in 3.8 years..

*Per US Department of Energy Averages

"I was blown away the first time I walked in the gym after the new lights were installed. I am confident our entire athletic conference will appreciate the new lighting as the once uneven and shadow-filled gymnasium has been transformed into a crisp, clean gym. I am extremely happy and proud to call this our home court and look forward to playing and practicing in the middle of winter when it will be dark outside."- Mark Geweke, Roosevelt Middle School Athletic Director
