DENVER – Denver International Airport (DIA) is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures.

The majority of the lights are being replaced with 51-watt LEDs. Combined with other lighting systems in the project, DIA expects a net energy savings of about 45 percent, resulting in energy cost savings of about $327,000 per year.

“By replacing the existing lights with energy-efficient LED lights, we will reduce Denver International Airport’s energy consumption and save a substantial amount of money over time,” Kim Day, Denver’s manager of aviation, said. “This project will also make the parking garages brighter and more evenly lit, increasing visibility and enhancing safety.”

Construction on the lighting project will begin this month and should take about one year to complete at a cost of $2.7 million. The project also qualifies for Xcel Energy’s Lighting Efficiency rebate program. The LED light fixtures will be assembled locally by Denver-based Cooper Lighting.
