Cree and LED lighting are starting a revolution

Indiana Tech upgrades oldest building on campus with LED lighting

Tuesday, November 23rd, 2010

Built in 1857, the Administration Center at Indiana Tech University is a landmark for generations of alumni who know that even as the campus grows, they can always count on recognizing the familiar historic brick building when they visit.

And now, the oldest building on campus is historic for another reason: It’s the first building on campus to boast energy-efficient Cree LED lighting.

The 153-year-old building was gutted for renovation in October 2009 with the goal of achieving LEED (Leadership in Energy and Environmental Design) certification. The resulting work transformed the pre-Civil War era building into a haven of energy-efficient technology and sustainable design.

The historic Administration Center at Indiana Tech is a landmark for alumni.

When architect Terry Thornsbury of Viridian Architectural Design began planning the project, he said he knew he wanted to incorporate LED lighting.

“We wanted something that would help get us as many points as possible in the LEED system and reduce energy but also have a pretty good return on investment,” Thornsbury said. “Anyone who comes to me saying they want to save energy, the first thing I’m going to tell them is you’re going to want to do LED lighting because it makes sense these days to reduce energy consumption.”

Ninety-eight percent of the building is lit with Cree LED lighting.

The three-story building is lit 98 percent with Cree LED lights, helping the Fort Wayne, Indiana-based college conserve energy, reduce maintenance and provide beautiful light for employees, students and alumni. The 10,957-square foot building features:

  • 97 Cree LR24™ LED troffer lights. Offices, conference rooms and corridors illuminated with beautiful, clean white LED light. Each light consumes only 44 Watts while delivering 3,200 lumens. The high-quality light features rates 90 on the Color Rendering Index with a color temperature of 3,500K.
  • 61 Cree LR6C™ LED downlights.  Each light consumes only 10.5 Watts while delivering 650 lumens. The lights rate 92 on the Color Rendering Index and also feature a color temperature of 3,500K.
  • Long lifetime. The Cree LED lights are designed to last 50,000 hours. At the 50,000 hour mark, Cree’s LED lights are designed to provide at least 70 percent of their initial light output. That means the lights in the Administration Center could last more than 19 years based on the university’s projected use of 10 hours a day, five days a week.
  • Energy Efficiency. Over the long life of the LED lights, compared to a fluorescent downlight, the energy-efficient lighting in the Administration Center can save an estimated 259,700 kWh, which avoids 270 tons of carbon dioxide emissions.
  • Intelligent Control. The Cree LED lights work with an Intelligent Lighting Controls system with occupancy sensors and daylight harvesting, a control system that helps conserve even more energy by automatically adjusting the light level based on how much natural daylight is shining through the building’s large, preserved windows.

The University also worked with Primary Engineering, Inc., a Ft. Wayne, Indiana-based firm dedicated to sustainable design and CM Buck and Associates, Inc. which distributes Cree LED lighting in the Ft. Wayne area.

Indiana Tech Facilities Director Mike Townsley said he was skeptical an all LED-lit building would provide enough light for employees to work under. But that hasn’t been a problem, he said. Instead, employees are taking advantage of dimmers installed in each room. He said most employees are keeping the lights in their offices dimmed to 50 percent, which helps save even more energy.

“We’ve heard positive feedback about the lights,” Townsley said. “So far I’m pleasantly surprised.”

Mike Peterson is one of the university officials who moved into the newly-renovated building in July. He said he likes the controllability the dimmer in his office offers. He also enjoys the quality of the LED light.

“There’s good light distribution around the room,” Peterson said. “It doesn’t feel like there are dark areas or shadows.”

As director of Alumni Relations, Peterson says there’s another benefit to the LED lighting: Alumni like it.

“When you’re talking with alumni, any time you’re doing anything that’s technologically advanced it’s a plus,” Peterson said, adding that it’s a bonus that LED lighting technology is helping the school conserve energy. “[Alumni] feel like we’re being smart with the money that’s invested by them,” he said.

The building houses the Alumni Welcome Center, which is designed to be an inviting place complete with a fireplace made with bricks salvaged from the building. The warm, recessed Cree LED lighting adds to the ambiance, he said.

The Administration Center renovations were made possible by a $2 million donation from alumnus Wilfred Uytengsu, Sr., who wanted the money to go toward energy-efficient improvements. The building was recently renamed the Wilfred Uytengsu, Sr. Center in his honor.

And while Thornsbury was initially hoping to achieve LEED Silver level certification, the project exceeded expectations and has been submitted for Gold level certification. We’ll let you know when Indiana Tech receives final word from the U.S. Green Building Council.

Happy anniversary to the first LEED-certified McDonald’s in North Carolina

Thursday, July 15th, 2010

Four years ago, Ric Richards had to decide what to do with an aging McDonald’s franchise he just purchased in Cary, NC. The 25-year-old building was going to need “serious reinvestment,” he said, requiring major renovations to the front of the restaurant and drive-thru.

So Ric decided to do something he dreamed of ever since stepping foot in the first green McDonad’s in Savannah, Ga. He decided he was going to tear down the old McDonald’s and go for the gold. Ric wanted to achieve a gold LEED certification from the U.S. Green Building Council.

Here's what the Cary McDonald's looked like before it was rebuilt.

“This was going to be the right thing to do,” Ric told me when I interviewed him last year about his decision.

Today marks the one-year anniversary of Ric’s dream coming true. The green McDonald’s in Cary’s Saltbox Village shopping center opened its doors one year ago today, and Ric and his crew are inviting the public to celebrate from 4 to 7 p.m. (for those readers who live in the area).

Once the decision was made to demolish the old McDonalds, 99 percent of the building materials were recycled. Then, a variety of sustainable goods – from tables made of bamboo and sunflower seeds to denim insulation – were used in the reconstruction. And, of course, we were thrilled when Ric decided to light the restaurant, inside and out, with LED lights.

Here's what it looks like today.

In fact, 95 percent of the restaurant is lit with energy-saving LED lights. Nearly all of the general illumination inside the McDonald’s comes from Cree LED lights. And the LED lights in his store consume 78 percent less electricity compared to a standard lighting package at other McDonald’s restaurants.

We’re proud of Ric’s accomplishment and thrilled that his new energy-efficient lights helped him achieve his dream. Now would someone please bring me some chicken McNuggets? I hear they look better under LED lights.

North Carolina’s first green McDonald’s uses LED Lights (and cotton, bamboo, recycled glass and more)

Tuesday, January 5th, 2010

Take a quick look at one McDonald’s in Cary, NC, and you might not guess that it’s different than every other McDonald’s in North Carolina. But step inside and you’ll see why this McDonald’s in the Saltbox Village shopping center is making history.

The restaurant is the first green McDonald’s in the state, on track to receive its LEED certification from the U.S. Green Building Council later this month. (Take a look at the 25+ year-old McDonald’s v. the new one. Approximately 99 percent of the debris generated by the demolition process was diverted from landfills by either being reused or recycled).

I recently visited the restaurant to chat with franchise owner Ric Richards about why he chose LED lights to light up 97 percent of the store. Turns out the LED lights in his store consume 78 percent less electricity compared to a standard lighting package at other McDonald’s restaurants.

The restaurant was designed to take advantage of natural light and uses a fully automated, intelligent lighting-control system that combines light from Cree LED lighting and daylighting from Solatube skylights. There’s even a photo sensor to maintain the proper light levels on work surfaces. So, if it’s rainy and overcast outside, the LED light levels are increased to compensate. And since the system is automated, it’s not up to an employee to notice the changing light levels and fool around with the switches. How cool is that?!

Of course, there are many other neat steps taken to use green technologies, and there’s even a touchscreen video kiosk at the front of the store that shows off some of technologies. Here’s a video featuring some of the neat building materials used in construction and my interview with Ric about the energy-efficient LED lights:

Stay tuned, we’ll be updating you soon on the official LEED certification of Ric’s franchise.
