How can grocers make their fruits and veggies pop? Hint: It involves LED lights

Thursday, August 12th, 2010

The ladders at a Michigan-based grocery chain are being used a lot less these days now that the produce sections are lit with Cree LED lights.

Up until a few months ago, employees at the three Value Center Marketplace stores used to haul out the ladder every couple of weeks to replace the burned out 90-Watt Par 38 spotlights that lit up the fruits and veggies, according to store owner Ron Fariada.

But earlier this summer, Ron replaced the energy-wasting incandescent lights in the produce sections at all three of his stores with energy-efficient Cree LRP-38™ LED lights. His new LED lights consume only 11 Watts of energy and provide beautiful, warm light that helps make the color of the store’s fruits and vegetables pop.

“It’s just worry free,” Ron said. “I’m not going to have to worry about changing any bulbs for years. There was an upfront cost, but you’ve got immediate savings as far as power.”

When Ron opened the first Value Center Marketplace in 1989, he was committed to offering the freshest quality foods and the best in family value. More than 20 years later, Ron now runs three of the grocers just outside Detroit, Michigan.

In all, he replaced 50 incandescent lights at each of stores with Cree LRP-38 lights, for a total of 150 LED lights.

Ron said he expects a two-year payback on his LED lights when he takes into account the energy savings and maintenance savings. The produce lights in his stores are on for about 12 hours a day, seven days a week. And since the LRP-38 LED lights are designed to last 50,000 hours, Ron could continue to save energy and money for another nine years before he needs to consider replacing the lights.

Already he’s noticed that when he walks under his new LED lights, the area feels cooler than when the 90 Watt incandescent spotlights were lighting up the area.  Ron said he also expects to see HVAC savings.

The produce at Ron’s stores is hand-picked daily from the local farmers market. And now, it can truly shine under LED lights.

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.

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.

In January, the USBGC announced that Rich’s goal had been achieved. The Cary McDonald’s earned gold LEED certification.

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.

Oldest parking deck in Durham, NC, receives major facelift including LED lights

Tuesday, June 22nd, 2010

In 1964, the city of Durham, NC, began construction on its first parking garage. The Corcoran Parking Garage is still heavily used more than 45 years later, providing daytime parking for downtown workers and evening parking for theater-goers at the Durham Performing Arts Center and even baseball fans at the nearby Durham Bulls Athletic Park.

Renovations on the aging garage began last year, and are being wrapped up this month. Among the new features are 200 LED lighting fixtures, which dramatically improve visibility in the newly-painted garage.

I walked through the deck after a recent Durham Bulls game to get footage of the new lights and I kept declaring how amazing it was. As a former Durham resident, I’ve actually been inside this deck when it was lit with the dingy metal halide lights, and the deck felt older and not as safe. The difference with the new LED lights was truly extraordinary. There were no shadows and the signage was easily readable.

City officials say the new LED fixtures use only one-fifth of the energy consumed by the metal halide fixtures they replaced. At the 0:52 mark in this video, you’ll really notice the dramatic difference in lighting if you look at the contrast of the orange high pressure sodium streetlight glowing in front of the garage.

As part of other renovations, the City of Durham is currently installing LED lighting in another downtown parking deck and has plans for yet another. The Bull City, as it’s affectionately called by locals, joined the LED City program last month, and plans to continue considering energy-efficient LED lighting as it renovates and constructs new buildings and structures.

For a look at some original photos of the Corcoran Parking Garage as it was being built in 1964, check out this blog post on Endangered Durham.

Cree to provide LED lighting for kitchens in new Habitat for Humanity homes

Wednesday, May 26th, 2010

Cree LED lights will soon light up kitchens in thousands of homes built by Habitat for Humanity. Last week Cree announced its three-year, $1.5 million pledge to Habitat for Humanity International to provide our newest LED downlight for the kitchens in all new Habitat homes built in the United States.

Specifically we’ll be providing our CR6™ downlight, which is targeted to go to market this summer for about $60 each. This 10.5 Watt downlight is designed to last 50,000 hours, which means if homeowners use these lights four hours a day, they shouldn’t have to replace them for more than 30 years.

We’re very excited about this pledge because it can help reduce electricity costs for low-income homeowners. Habitat for Humanity already works to build homes that are more sustainable and efficient, and the addition of LED lights will help these homes save more energy.

In North Carolina, a Habitat homeowner should save almost $450 over five years by having the CR6 down lights installed instead of the currently-used halogens.* For a house in California, that jumps to nearly $600 in savings.*

A couple of weeks ago, I got to visit a Habitat home being built in Durham, NC. We delivered two of the CR6 downlights. My boss climbed up on a ladder to show the crew how to install the lights. All he did was take the trim off the existing fixture, unscrew the energy-wasting Halogen light and screwed in the CR6. Since I filmed him doing it, I was able to time him, and it took him 28 seconds! But you’ll have to take my word for it, because I’m not sure he’s ready to make his YouTube debut quite yet.

However, I also filmed the installation of the next CR6 by David Larkins, the construction director for Habitat for Humanity of Durham. I pulled him aside afterward to talk to him about the LED lights that were just installed. At the time he had no idea Cree was planning on putting these lights in kitchens at thousands of Habitat homes. Here’s what David had to say:

“We try to make a house that’s really easy to maintain, and energy efficiency is part of that,” he said. “A lot of the energy-efficiency improvements that we do just make a home that is smarter and simpler to maintain.”

Cree designed the CR6 specifically to make LED lighting more affordable for residential applications and we couldn’t think of a better residential application than inside homes for Habitat for Humanity.

*We came to this conclusion by using a North Carolina electricity rate of 9.42 cents per kWh and a California rate of 15.69 cents per kWh. We calculated four lights turned on 6 hours a day.

Extraordinary energy savings achieved in the Rayburn House Office Building Cafeteria

Wednesday, April 21st, 2010

LED lighting is continuing to work its way into Washington, DC. Cree LED lighting was recently installed in the Rayburn House Office Building Cafeteria, a move that can result in big energy savings.

Just how big? Well, the incandescent lights that were previously used in the cafeteria consumed more than 6,000 Watts of energy. The new Cree LED lights along with advanced building controls consume a total of about 1,200 Watts. That’s an 80 percent energy savings. Even better, these energy savings can be achieved while improving the quality of light in the cafeteria.

The Rayburn project included replacing the existing fixtures with 46 Cree LR24 Architectural Lay-in LED fixtures and 51 Cree LR6-DR650 LED Downlights.  House Speaker Nancy Pelosi was on hand today to tout the energy savings. Check out this Twitpic from Tuesday’s press conference by Rep. Debbie Wasserman Schultz:

Pelosi

In addition to the energy benefits of the LED lights, the extremely long life (they’re designed to last 50,000 hours) of the fixtures can provides year of virtually maintenance free operation. Seriously, these lights could last nearly 20 years running 10 hours a day, 260 days a year. This can help avoid the economic cost of lamp replacements. That also can mean less waste in our landfills. It could take about 1,200 incandescent bulbs to last as long as the LED lights and nearly 350 toxic mercury containing fluorescent lamps.

Here’s hoping the federal government continues to see the light on energy-efficient LED lighting.

An LED flashblack: The 2009 NCAA men’s basketball championship celebration on Franklin Street

Monday, April 5th, 2010

This time last year, all eyes were on Chapel Hill, NC, after the Tar Heels secured the Men’s NCAA Basketball Championship. Fans filled Franklin Street, celebrating the win in true Tar Heel style, by taking the fun to the streets.

Many of us watched the revelry from the comfort of our couches. On TV, we saw thousands of students and fans dotting the main drag through Chapel Hill, cheering and jumping over fires. At Cree, we watched intently for other reasons.

About a week before the championship game, ten high-pressure sodium (HPS) streetlights on Franklin Street were replaced with LED streetlights. The orange glow cast by the HPS streetlights was cast aside and the white light produced by the new LED streetlights helped make colors pop.

The LED streetlights were installed in the 100 block of Franklin Street where students and residents gather to celebrate events like Halloween and big Tar Heel wins.

UNCHPS

Flickr user benuski posted this picture of Franklin Street during the 2009 NCAA Men’s Basketball Championship celebration. Note the orange glow from the HPS streetlight.

Since the LED streetlights help make colors pop, it was easy to see which section of Franklin Street featured the energy-saving LED lights and which section was still stuck with the dimmer HPS streetlights. In the LED-lit section, you could actually see the Carolina blue T-shirts Tar Heel fans were rocking. In the HPS-lit section, it just looked like a dingy, orangey mob with some semblance of blue mixed in.

Take a look for yourself in this time-lapse video The Daily Tar Heel produced of the Franklin Street celebration last year. You’ll see the LED-lit side of the street on the left and the dingy HPS-lit side on the right:

See, looks like the LED Lighting Revolution has game.

High Definition screens at American Airlines Center put HD in every seat

Friday, March 26th, 2010

I’ve been known to jump up and down or wave my scarf at hockey games in hopes of being projected on the big screen in between plays. But if I ever attend a Dallas Stars game, I’d probably check my hair and makeup before I attempted to attract the cameras.

That’s because the American Airlines Center now features high definition screens, which means Dallas Stars and Dallas Mavericks fans can now experience HD in every seat. And let’s face it, few people would enjoy being projected in HD in front of a stadium full of people with Alfalfa hair! But how awesome would it be to follow game highlights in HD (especially if your seats are in the nosebleed section).

I know we focus closely on the LED lighting revolution – helping the world ditch its addiction to incandescent and fluorescent bulbs. But our LEDs are also used in some other neat applications, and when I hear about uses such as these massive HD screens, I have to share them!

Here are some pictures:

So how many Cree LEDs are used to light the 25 individual screens at the American Airlines Center? 13 million. Pretty incredible, huh?

California city once known as a getaway for Hollywood stars turns focus to sustainability

Tuesday, March 9th, 2010

Most people who visit Indian Wells, California, are probably drawn in by the four world class resorts, the spas and the lush golf courses. The resort community in the southern California desert became a retreat for celebrities after Lucille Ball and Desi Arnaz opened the Indian Wells Hotel in 1958. Since then, city officials have worked to make Indian Wells a premiere destination in the Coachella Valley.

Indian Wells 009

These days, city officials are keen on sustainability, and energy-use reduction has become a key goal for the city. I had the “tough” job of visiting Indian Wells last month for an LED City® Council meeting, and while I was there I had the city’s management analyst Susan Weisbart give me a tour of some of the city’s LED lighting installations.

Indian Wells was the first California city to become an LED City. The LED City program helps municipalities speed up the adoption of energy-saving LED lights by connecting them with information they need to make informed decisions about installing LED lights.

One of the first LED lighting installations in Indian Wells involved swapping out incandescent lights that lit the outside of city hall and other municipal buildings with 12 Watt Cree LR6™ recessed lights. It’s a change that city officials say saves nearly $7,000 a year in energy costs. That’s not counting the maintenance savings of not having to replace burned out bulbs, since the LED lights they installed are designed to last 50,000 hours – or 17 years if they’re on 8 hours a day!

The city also has plans to replace the 50 Watt halogen lights illuminating the signature palm trees lining city streets with 11 Watt LED lights. Get this: The city estimates it can save $10,095 in energy costs per year once the project is complete!

Watch my LED tour and interview with Susan to see what Indian Wells is doing to save energy and money:

Orlando resort converts hundreds of fixtures to LED lights, projects to save $131,000 in first year

Thursday, February 25th, 2010

One of the biggest perks of LED lighting is how much energy it saves. We’re living in a world where it’s crucial to conserve resources. And a perk of saving energy is that it typically translates into fewer dollars on utility bills.

But it’s one thing to say you’ll conserve energy and reduce utility bills when you use LED lighting, and it’s another thing to actually experience the savings. So when I heard how much energy and money a large Orlando resort is saving by using LED lights, I had to share the details with you.

The Hyatt Regency Grand Cypress Resort is one of the largest resorts in Orlando, Florida, and it recently underwent a multi-million dollar renovation that included replacing traditional, antiquated lighting fixtures in its 54 hallways, as well as its freshly refurbished 10,000-square-foot lobby.

4186305688_fdb08aeb1b_bAdd New

The amount of energy and money the resort is saving with its new LED lights is remarkable.

According to Regency Lighting, replacing the resort’s hallway lighting with Cree LR6™ recessed downlights is projected to have a cumulative savings of approximately $131,659 in the first year, with a return on investment of about nine months. These savings include projected energy, labor and cooling expenses, as well as the cost of the new LED lights. By the fourth year of the LED lighting installation, this resort is expected to save more than half a million dollars!

LED lights make good sense for the resort’s lobbies and hallways because they’re lit 24-hours a day, seven days a week. The resort replaced halogen lighting fixtures located between each hotel room with 636 Cree LR6 LED lights. Those lights only consume 10.5 watts of power, an impressive 90-percent energy savings over the two 50-watt halogen bulbs they replaced! But they didn’t stop there.

4186301986_5ec7d9d2f1_b

In the hotel’s lobby – which features live bamboo, animal statues and an indoor garden – halogen lights were replaced with Cree LRP-38™ LED bulbs, saving more than 80 percent on energy consumption alone.

So the next time you’re staying at a hotel look up at the lights in the lobby and hallways. If they’re not LED lights, tell the manager the hotel needs to join the LED lighting revolution. After all, one of the key parts of a revolution is rallying others to join the movement.

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).

CaryMcDonaldsOldNewCaryMcdonalds

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.
