Denver International Airport
Retrofit Team
Lighting Installers: Denver International Airport maintenance personnel
Materials
To improve optical performance and efficiencies at the airport, maintenance personnel replaced more than 5,400 high-pressure sodium parking garage fixtures with almost 5,000 McGraw-Edison Valet LED luminaires. The installation of the LED products will consume only 51 watts compared to the HPS fixtures, which consumed 177W.
The conversion is expected to result in a 45 percent energy savings and reduce annual energy consumption by more than 3.4 million kilowatt hours per year, or 68 million kWh over the expected 20-year life of the McGraw-Edison Valet products. The yearly carbon reduction associated with the project is equivalent to the electricity used by 356 homes or taking 544 cars off the road each year. The long-lasting fixtures also will provide maintenance savings with fewer lamp replacements, reducing labor and material costs. The retrofit is expected to help the airport save approximately $327,000 annually, or $6.5 million over 20 years.
Additionally, more than 700 Valet 73W fixtures reduce the wattage used in 250W and 150W HPS products, and 27W Valet products replaced metal halide surface-mounted downlights consuming 115W.
The DesignLights Consortium- (DLC-) listed LEDs brighten and uniformly light the DIA East and West parking garages, increasing visibility and enhancing safety for the airport’s customers while shrinking the airport’s carbon footprint.

The Retrofit
Because the McGraw-Edison Valet LED lighting fixtures are DLC listed, they qualify for a local utility rebate from Xcel Energy’s Lighting Efficiency program. The DLC distinguishes quality, high-performance LED products for commercial and industrial projects and produces a Qualified Products List to save time and provide peace of mind to lighting specifiers and property owners selecting products to support sustainable design practices. As a result, the airport is anticipating a rebate of approximately $630,000.
Construction of the multimillion-dollar project began in May 2014 and was completed in November 2014.
