Dunkin Donut

Dunkin Donut


The average American stops at a quick-service restaurant 150 times a year. With this many impressions, fast-food restaurants have great opportunity to create positive environmental impacts as they enter the green-building arena.

Recent efforts in corporate strategies and enterprising franchisees are sprouting new models on how to serve up sustainability. Dunkin' Donuts is the world's leading baked goods and coffee chain, serving more than 3 million customers per day. Dunkin' Donuts sells 52 varieties of donuts and more than a dozen coffee beverages as well as an array of bagels, breakfast sandwiches and other baked goods. Today, there are more than 11,300 Dunkin’ Donuts restaurants worldwide – more than 8,000 Dunkin’ Donuts restaurants in 41 states in the U.S. plus the District of Columbia, and more than 3,200 international restaurants in 36 countries.

Dunkin Donuts is continually initiating environmentally positive changes without compromising operational standards. The company’s employees and leadership are engaged and committed to developing ways to deliver consistent policies and practices across all of their operations globally. Since 90 percent of Dunkin Donuts fast-food coffee shops are owned by franchisees, new franchisees are challenged with implementing efforts towards a green vision by creating an exceptional and memorable dining environment that also incorporates a smaller carbon footprint, reduced utility costs and increased labor efficiencies. Hence the DD green Initiative was launched As franchisee Mahesh Patel began making plans to open his new franchise, he wanted to find a way to reduce utility costs. So when Mr.Patel set out to construct the new restaurant in the central Michigan town of Kalamazoo, it ordered energy-efficient AcculightUSA LED lighting instead of traditional metal halide fixtures to illuminate the parking lot, drive-thru bay, walkways and more.


AcculightUSA exterior luminaires that were chosen over the metal halide solution provide dramatically improved uniformity, eliminating dark spots between fixtures.

AcculightUSA luminaires installed in the restaurant’s parking lot feature custom Optic Reflect Technology that helps reduce light pollution by directing light into desired target areas without casting light onto neighboring properties or into the night sky.

The Wall pack luminaires mounted under the canopies of the windows, customer entrance and drive-thru bay of the restaurant also provide targeted light without spilling into adjacent areas.

And with a mind towards employee and patron safety, AcculightUSA Area/Parking lot luminaires illuminate the employee and service entrance behind the building as well as the perimeter walkways.

In keeping with the corporate sustainability goals, AcculightUSA LED fixtures offer superior lighting that meets the required uniformity and spill light requirements of the site, as well as the sustainable illumination performance requirements that were set.


Mr.Patel and his business group were willing to make the initial investment in Acculight luminaires over a traditional lighting system because they anticipate recovering the additional cost of the LED system in approximately two years.

“It just didn’t make sense to build a new restaurant with the latest technology and building materials but install outdated lighting fixtures,” said Mr. Patel. “AcculightUSA luminaires provide very consistent and uniform illumination without having any light spilling to adjacent properties.”

And the restaurant will continue to rack up the savings. Energy use is expected to decrease an estimated 74 percent as a result of selecting AcculightUSA LED lights over metal halide fixtures After opening, the restaurant was exceeding expectations and receiving positive consumer feedback, particularly on the inviting exterior lighting.The parking lot, restaurant perimeter and walkways are all brilliantly illuminated, providing a welcoming and safe environment for patrons and employees.
