Case Study: Chicago Board of Trade Building
The Chicago Board of Trade building is an iconic historic landmark in downtown Chicago, IL and is the primary trading venue for the derivatives exchange. American Green Lights provided numerous innovative retrofit solutions to convert outdated lighting technologies to LED, with electricity savings of 55% to 90%!
Outdoor Accent Lighting: Conversion from Fluorescent T8 to LED Retrofit Strips. Electricity Savings of 65%
CBOT management was frustrated with the constant fluorescent tube replacements and poor low temperature light output of fluorescent lamps in the winter. Fluorescent T8 lamps operate optimally at 75 degrees Fahrenheit and performance drops below 10% of normal light output at sub freezing temperatures, a common winter issue in Chicago
American Green Lights retrofitted the T8 fluorescents with our wing-type LED retrofit kit strips and drivers for a 65% electricity reduction and increased light output by 20% during the summer months and over 500% during the winter months. LED performance is not degraded by cold temperatures.
indoor Service Area Lighting: Conversion from Fluorescent T8 to LED Retrofit Strips Electricity Savings of 65%
CBOT has several dozens of utility rooms, service rooms, mechanical rooms, pump rooms and other facility engineering areas, that need constant fluorescent tube replacements, with many areas operating 24/7.
Utilizing American Green Lights 4ft LED retrofit kit strips to replace fluorescent tubes, CBOT engineers attached the strips to the fixtures in place of the fluorescent tubes saving the expense and time of replacing complete fixtures. The high Color Rendering Index (CRI) of the strips improved overall visibility and safety within the service areas.
