a Denny’s franchisee in Illinois. In 2009, Terrell opened his second restaurant in Joliet, a suburb of Chicago. Built according to Leadership in Energy and Environmental Design (LEED) Gold standards, the Joliet Denny’s includes a combination of natural lighting and Cree LR6 LED downlights to reduce the restaurant’s lighting load.
According to Terrell, this lighting design reduced utility costs by 83 % and his electricity bill is now around $1,000 a month instead of the expected $2,100 a month based on the average costs for his Mokena, Ill. location.
“Restaurants use 285 % more utilities than the average commercial building,” said Terrell. “The easiest way to reduce these costs and improve energy-efficiency is to switch from traditional fluorescents to daylighting and LEDs, and that’s what we did.”
“Denny’s is a great example for any restaurant chain looking to become more energy-efficient,” said Craig Lofton, Cree LED Lighting vice president of sales. “Not only can switching to LED lighting offer energy savings and maintenance avoidance, but the Cree LR6 downlight delivers the quality of light customers want.”
Cree is a market-leading innovator of lighting-class LEDs, LED lighting solutions, and semiconductor solutions for backlighting, wireless and power applications.
Cree’s product families include recessed LED down lights, blue and green LED chips, high-brightness LEDs, lighting-class power LEDs, power-switching devices and radio-frequency/wireless devices. Cree solutions are driving improvements in applications such as general illumination, electronic signs and signals, variable-speed motors, and wireless communications.
