Graybar Helps Rauhorn Electric Light the Detroit Metropolitan Airport

Graybar Helps Rauhorn Electric Light the Detroit Metropolitan Airport

Opportunity

The Detroit Metropolitan Wayne County Airport (DTW) is one of the world’s leading air transportation hubs. In 2014, DTW welcomed more than 32.5 million passengers.

When the airport wanted to improve both energy efficiency and optical lighting performance of its main parking decks, it turned to Michigan-based contractor, Rauhorn Electric, Inc. Specializing in traffic signals, street lighting, traffic control and monitoring system installations and high mast lighting for roadways, parking lots and airports, Rauhorn knew it needed a distributor that would be up for the challenge.

That’s when Rauhorn called on Graybar, a leading distributor of high-quality electrical, communications and data networking products and provider of related supply chain management and logistics services. Rauhorn had worked with Graybar on past projects and was familiar with the services and the logistical support the distributor could provide.

Solution

After evaluating many different lights, DTW selected the Eaton Cooper Lighting 60-watt McGraw-Edison Valet LED fixtures to replace the 1,200 existing 210-watt, metal halide fixtures in the Blue Deck parking garage and 4,800 fixtures in the McNamara Terminal Parking Structure. For the upper open decks, the airport selected Eaton Cooper Lighting’s Ventus LED pole-mounted fixtures. Light levels will be managed by the LumaWatt Outdoor Wireless Control and Monitoring System and will be based on pedestrian traffic and safety needs. This will allow the airport to better monitor and regulate energy usage to reduce costs.

Since space for receiving material for the project at the airport was limited, Graybar agreed to stage the project from its Belleville, Michigan, warehouse. Graybar also performed daily deliveries to predetermined sections of the jobsite. The project began in October 2013, and included a timesensitive installation for the first 4,800 fixtures; in order for the project to qualify for an available rebate from the power company. To meet the deadline, Graybar helped Rauhorn speed up and streamline the installation process by uncrating and unpacking the fixtures at the warehouse, and then safely loading each fixture into the truck to be delivered and installed quickly at the job site.

“We had it down to a science,” said Graybar Sales Representative Joe Duster. “Our close relationship with the manufacturer enabled us to develop a packaging solution that took less than 30 seconds to unpack, while still protecting the fixtures from damage. Efficiency was key. It was a high-profile project with a strict deadline.”

The fixtures were installed in two months, successfully meeting the rebate deadline. The second set of fixtures included 2,400 fixtures of eight different types and was completed in summer 2014.

Results

The airport’s new fixtures are estimated to reduce annual energy consumption by more than 7,345,000 kilowatt hours, resulting in 66 percent energy savings with an anticipated overall energy and maintenance savings of approximately $1.2 million annually.

The replacement LEDs will also provide maintenance savings, including labor and materials. On average, the existing light source needed to be replaced every 13 months, whereas the new ones are designed to last more than 60,000 hours, or maintain minimal light levels for at least 10 years.

Since the project began, the airport has decided to add even more fixtures to the installation process. Additional fixtures are set to be installed throughout the parking garage and other surrounding areas of the airport facility.

The new lighting fixtures are estimated to reduce annual energy consumption by more than 7,345,000 kWh, resulting in 66 percent energy savings with an anticipated overall energy and maintenance savings of approximately $1.2 million annually.
