Brookdale Senior Living has completed its nationwide lighting retrofit throughout the company’s 546 senior care communities. The initiative is estimated to save $5 million annually in electric utility costs and deliver a return on investment over about one year. The project also provides energy savings of approximately 75% and gives 30% more light to the residences.
The facilities primarily used products from TCP Inc.’s range of compact fluorescent light (CFL) bulb styles. The lamps have an expected lifespan of 10 to 15 times the incandescent products they replaced. Brookdale was able to participate in utility rebate programs offered around the country, and selected some specific TCP lamps in order to qualify for the rebates, including many GU-24 base lamps.
Brookdale also used the “InstaBright” CFL line from TCP in bathroom vanity applications. Other TCP products that were used were Flat Face Par 20’s, 30’s and 38’s, decorative CFL’s and some LED lamps in night lights and nursing call applications. The installments focused on retrofitting existing fixtures in exit signs, corridors, bathrooms and resident rooms. The project also included signage and outdoor lighting when appropriate.

Whitehead & Associates, an Atlanta-based electrical manufacturer’s representative, specializing in commercial and industrial lighting, executed the lighting retrofit project in each of Brookdale’s communities over a two-year period using Brookdale in-house maintenance teams. About 95% of the lighting fixtures in the communities had a savings opportunity.
“The one common goal we had was to maintain the safest and most comfortable environment for our residents. Ultimately, we were able to accomplish this objective with the right lamp choices, which significantly cut lighting consumption and increased light levels by more than 30 percent,” Jeff Patton, Vice President of Procurement at Brookdale Senior Living.

Nally Lexus in Georgia Completes LED Parking Garage LED Retrofit
“Auto dealers want to focus on satisfying customers, not worrying about burned-out light bulbs,” said George Karolis, vice president of corporate development and real estate at Asbury Automotive Group. “I believe every automotive dealer confronts the same set of challenges with their lighting infrastructure—it consumes too much electricity, the bulbs burn out frequently and the quality of the light is poor given the amount of energy used.
Qnuru retrofitted Nalley Lexus of Roswell’s exterior pole-mounted parking lot lights with its 144 watt Vector Pecos bulb. Designed to replace energy intensive 750-1000 watt high intensity discharge lamps, the Pecos bulb offers an even photometric footprint, daylight-quality light (CRI of 74.8) and instant on capabilities. The Pecos bulbs are based on high bin Cree LEDS (Nasdaq: CREE) which have a rated life of 50,000 hours and come with Qnuru’s 5-year warranty, independent LM79 verification, and are ETL-Classified in the U.S. and Canada.
“Auto dealers are important business beacons within their communities,” said Rhonda Dibachi, President and CEO of Qnuru. “Nalley Lexus of Roswell’s adoption of energy-efficient LED technology is a great illustration of leadership by example. LED lighting solutions help businesses lower their carbon footprint as well as reduce their operating costs. In a world filled with difficult tradeoffs, LED lighting is a rare win-win for both the environment and business owners.”
LED Lighting Used in Film Production
Illuminating Choices
By Christine Bunish
Republished from Markee 2.0 Magazine
New lighting fixtures continually come on the market offering shooters and lighting designers new creative options and greater efficiencies. But adding these revolutionary or evolutionary new products to their lighting kits doesn't mean discounting the instruments they've come to depend on job after job. A noted tabletop director, a leading advocate of HDSLR video, a distinguished underwater cinematographer and an in-demand lighting designer share the contents of their lighting kits today.
For tabletop commercial director Tom Ryan, with Dallas-based Directorz (www.directorz.net), there are no formulas for lighting food spots. "It's all about appetite appeal," he says. "I try to give every client I work with their own look."Ryan primarily shoots film, although he has switched to the Phantom camera for high-speed photography, and uses a tight-grain slow film stock that demands "a certain amount of wattage" from his lighting package. He typically uses Mole-Richardson tungsten 20K, 10K and 5K fixtures for interiors and HMIs for exteriors supplemented with focusable spot sources, lekos and dedo kits.
Ryan has experimented a bit with LEDs "but for the amount of light we use, they're not always practical," he points out. "The beauty of LEDs is that they don't take a lot of power, they don't put out a lot of heat and they're great on location."Ryan's tried-and-true lighting approach with conventional fixtures gives him a lot of latitude to create the different looks and moods his spot clients require.
In Taco Bell's "Cantina Tacos" with lime commercial, "conceptually the lime was a character and we wanted it to really pop," he explains. Ryan shot the tacos bursting with filling, their shiny aluminum foil and a drop of juice clinging to a luscious lime wedge, with a pair of ARRI 35mm cameras. The exterior patio was lit with HMIs; for "ultra-macro" shots of the food he blacked out daylight and went back to tungsten sources.
Ryan's stylish "Whole Meals" spot for Whole Foods was "influenced by old-school Irving Penn photos with clean white backgrounds," he notes. "The challenge was not to let the background overpower what I was shooting" — simple, fresh ingredients, white table linens, butcher paper and brown bags. "It would have been easy to wash out what the focal point of the pictures should be, and if you went too much the other way things would have become muddy and gray. So it was pretty critical to keep the balances consistent." Ryan took light-meter readings of the backgrounds and foregrounds and aimed for 2.5 stops difference; once that was established he kept the balance consistent across the board with his usual complement of tungsten fixtures.
He even kept the white-on-white place settings "in the same range as if they were ingredients" making "some creative decisions" as he went along about how much fill to add to separate the tone on tone.Taco Cabana's evocative spot showing Lenore Segura in her kitchen assembling the ingredients for a brisket taco features "Rembrandt-style" lighting that "lets the shadows go and the highlights be simple and single source," says Ryan. "Where there were shadows on her we let them go dark, but we softly illuminated the walls behind her so the highlights separate the shadow." Ryan initially lit the spot with overhead Kino Flo sources then "backed away and decided it needed a more painterly feel," and turned instead to his trusty tungstens.
Slow liquid pours are part of a tabletop director's repertoire and Ryan's "Once a Day" spot for the Florida Department of Citrus showcases the appeal of a simple glass of orange juice against white limbo. Ryan shot the entire spot with a Phantom using a lighting scheme similar to what he would have used with a Photosonics high-speed film camera.
"It took a lot of light — 20Ks with dimmers," he recalls. "With the white background we needed twice as much light on the background as on the juice. When I'm shooting video I'd rather shoot it a bit wider aperture so you get a bit of fall off for a more filmic look." A broad source gave shape and highlights to the slow pours that wash up against the glass like waves in extreme close ups. Delicious!

Advantages and Disavantages of LED Lighting Retrofits
Interesting article on the advantages and disadvantages of energy efficient LED lighting retrofit covers some interesting points. Of course one of the key disadvantage of any lighting retrofit is the upfront cost.Many LED lighting retrofit companies offer financing programs. For example, Redbird LED based in Atlanta, works with Energy Finance a division of RedClay. Financing a lighting retrofit is obviously important and most visitors to their website visit the Financing info on their website. There are also many state, federal and utility rebate programs available to finance your energy retrofit investments. Some of these rebates pay up to 100% of the cost.

Energy and lighting efficiency questions are plentiful on whether or not to make a transition from traditional incandescent lighting systems to LED alternatives.According to a post at Buzzle, "Energy efficient lighting not only contributes to a better environment but also saves huge energy costs."
There are few arguments to this thinking except one, the cost. Just switching over traditional incandescent lights to LED lights comes with a significantly price tag, even if the life of the bulbs and the large energy savings they bring are scaled into the picture.
Some large retailers are making the transition. Environmental Leader recently reported that retailer Macy's was retrofitting 117,000 halogen-based accent bulbs in its 86 stores with LED bulbs. Macy's expects the retrofit will reduce the company's energy consumption by 73 percent. The total cost of the Macy's retrofit was not mentioned, however.
Buzzle provides these considerations for retrofitting, "LED fixtures cost more to purchase than the traditional light sources. There are many factors that contribute to the effective and economic performance of LEDs, so a range of payback scenarios exist. But a lower wattage luminaire significantly reduces the payback period."
There are three disadvantages to consider about LED systems, "First is its initial cost," says Anne Linden. Many people are used to the relatively inexpensive traditional light bulb, and the new LED lamps seem expensive in comparison. However, when you recognize that each lamp has an estimated lifespan of over twenty years, and only uses 5 percent of the electricity of the so-called "cheap" glass bulb, you can recognize the inherent value of the newer type. And much of that price differential was due to the fact that the technology is so new that companies were recovering their investment in research and development. Prices are already falling considerably as they become more common in the marketplace. And with the ever-tightening drive to economize on energy usage, they will become even more common in newer fixtures available in stores.
"The second disadvantage is the fact that they cannot be used in "regular" screw-in sockets. They require a GU10 socket, or a screw-in GU10 adapter," says Linden. However, this "disadvantage" may actually have a benefit as a safety feature. Traditional lamps can become cross-threaded and stick in the socket. When you try to use force to remove them, they often break. There is no danger of cross-threading with the GU10 style socket, you just push it in and give a slight twist; thus these bulbs are safer to use.
"Finally, the light from a led lamp is "different" from other lamps. These new LED's emit a more tightly focused beam, and you may need to do some research to determine what level of brightness you need, as wattage is not an accurate measure for this type. Look to see if the package gives equivalent output ratings compared to the wattage output levels we have all become used to," Linden concludes.

Macy's Department Stores to Save Millions of Dollars with LED Lights
Macy's worked with MSi Solid State Lighting on the lighting retrofit. Unlike hot burning halogen lights, the extremely efficient LED lights produce very little heat and within hours of installation, store employees had noticed a drop in the store's temperature. "Many retailers are a little concerned about the initial investment of converting to LED lighting," said Bruce Johnson, MSi managing partner, "But if they take the time to run the numbers as Macy's has, they'll see that switching over produces a tremendous return on their investment."LED lighting produces savings that go far beyond just cooling cost. LED's use a fraction of the power required by halogen spots while producing a clean, clear light that enhances product displays and merchandise.

SAP Saves $80,000 Per Year From LED Ligting Retrofit
SAP recently completed a series of energy retrofit projects including an LED lighting retrofit. GreenTech Media provided an interesting analysis of the energy savings from each type of energy retrofit.The LED lighting retrofit was number two n savings!By Michael Kanellos
Fluctuating energy prices, new regulations, employee satisfaction and market opportunities are prompting large and small businesses to adopt green technologies.But where do you get the most bang for your buck?
At the Palo Alto campus of SAP, the answer turns out to be videoconferencing. The company, as part of an overall energy retrofit, installed three telepresence systems from Cisco Systems in Palo Alto for a cost of $300,000. The units will save $300,000 in reduced travel costs in the first year alone. Besides that, they boost productivity.
Solid state lighting came in second place. SAP installed 337 LED fixtures from Lunera and connected them through a network from Redwood Systems. Total cost: $434,000. Annual savings: $80,000.“It is the best business case except telepresence,” said Peter Graf, SAP’s chief sustainability officer.
Retrofitting the data center to run on DC power came in fourth place, right behind a $1.2 million solar array, but the best part has yet to come for DC. The retrofit -- which largely revolved around installing a rectifier that can convert high voltage AC power from the grid into high voltage DC to run computers and storage equipment -- cost $128,000 and saves $24,000 a year. (DC rectifiers save power by reducing the number of times power gets converted from AC to DC and vice versa before it powers a server -- we’re huge fans of DC power these days).That’s a 5.3-year payback. Overall, the DC data center reduces power consumption in the data center by 15 to 20 percent, said Branitzky.

For years, SAP’s software mostly focused on parameters like factory productivity, cost-per-unit, etc. Now, the idea is to highlight building energy consumption, fuel costs and other direct and indirect factors tied to energy and resources. Right now, large companies largely estimate those figures through extrapolation. But in the future, soft drink managers will, ideally, be able to more easily mine data on changes to the water or fuel footprint of a canned soda over different energy pricing scenarios.
Regulations and rising energy costs are prompting large companies to try to better track resources. But price volatility is also a huge concern. In the last decade, commodity pricing has been 40 percent more volatile than it was in the previous decade, Graf noted. The uncertain future surrounding China’s exports of rare earth elements underscores the problem.

Saint Patrick's Episcopal Church Upgrades to LED Lighting in Retrofit Project
Redbird LED, an Atlanta, GA. firm that specializes in the design, manufacturing and distribution of energy efficient LED linear lighting, recently completed an energy efficient lighting retrofit project for Saint Patrick’s Episcopal Church. Founded in 1966, Saint Patrick’s Episcopal Church is located in the prestigious Atlanta suburb of Dunwoody, Georgia. The church contacted Redbird LED to explore ways they could both reduce energy and facility maintenance costs and lower their environmental impact at the same time.
Redbird LED worked with Saint Patrick’s to design a retrofit program targeting the older less energy efficient lighting in the church sanctuary and religious offices. Older 40 watt fluorescent tubes were replaced with more energy efficient 18 watt LED linear lights and the 150 watt incandescent spot light lamps were replaced by Dim-able 18 watt LED par lights. These were designed to be a direct screw-in replacement with excellent compatibility to the installed lamp dimming system.
The lighting retrofit will provide more than $5,000 per year in savings from the direct drop in electrical consumption, with additional savings from smaller air conditioning requirements due to the reduction in heat loads. Almost as important was the reduction in lighting maintenance time to replace the lamps. The LED lights have a lamp life of 50,000 hours eliminating the need for replacement for the next twelve years. This was very attractive because many of the lamps, such as those in the sanctuary, require scaffolding to service because they are more than 35 feet above the floor.

Starbucks Retrofits Lighting in 7,000 Stores
Starbucks recently finished replacing nearly all of its incandescent and halogen lighting with LEDs during a two-year roll-out to over 7,000 company-owned stores, most in the United States and Canada, but with some in Europe and Asia. This is the largest deployment yet of LED technology in an application that is very sensitive to the quality of light; Starbucks' success proves that the new digital lighting is ready for mass install.
Jim Hanna, Director of Environmental Impact for Starbucks confirmed that the LED lighting program is on target to slash consumption by more than 80 percent compared to existing lighting. My back-of-the envelope calculations [see notes below] found that
• Each LED light bulb saves approximately $30 annually in energy costs and eliminates the equivalent CO2 as half a barrel of oil;
• Each 1,000 square foot store on average would save nearly $600 annually and eliminate the equivalent CO2 as 10 barrels of oil
To capture these impressive benefits, for both the bottom-line and the environment, it took more than replacing a light bulb. When Starbucks was examining which energy efficiency projects to deploy in its stores, lighting was an obvious choice, since retailers consume a large amount of energy on lighting to provide ambiance and to showcase products.
But Starbucks had already installed energy-efficient fluorescents in many areas of its stores. The remaining halogen and incandescent lights were in its beverage and sitting areas. The soft, warm light provided by incandescent bulbs was critical to creating an inviting experience. And halogens were used to highlight products. Fluorescent was a poor fit in these areas due to its inferior color rendition. Although CFLs are prevalent in offices, older and inefficient lighting technology is common in many retail and other high-end applications.
Starbucks investigated LED lights and appreciated the low energy use and the quality of light, but LED products on the market at the time required replacing both the light bulb and fixture driving costs up considerably.

Retailers Save Money with LED Retrofits
As reported in Environmental Leader
Retail stores such as Timberland and Basset Home Furnishings are realizing the cost and environmental benefits of switching from traditional store lighting to LED lights.
Retail stores such as Timberland and Basset Home Furnishings are realizing the cost and environmental benefits of switching from traditional store lighting to LED lights.The Timberland Company has saved approximately $100,000 in electricity costs ten months after it partnered with Eco-Story to develop LED lighting track lights for its retail stores. Eco-Story developed special LED track lights for the footwear and apparel maker’s 50 retail stores across the United States.
Depending on each store’s location and size, Eco-story replaced up to 150 50- to 90-watt halogen spotlights per store with 10-watt Par 30 LED bulbs (featuring Cree XLamp LEDs) that were color-matched to client specifications.
“Eco-consciousness led the way in our endeavor to make lighting changes, but with the federal tax incentive and our lowered electric bill, the financial savings has been a significant advantage,” said Al Buell, store planning and construction project manager at Timberland.
In addition, there was no labor costs involved in the transition since Timberland store employees handled the easy lamp change, taking less than four weeks to complete in all 50 stores.
Timberland’s lights are predicted to last 6 to 10 years and have an extremely low failure rate, according to Eco-Story. Only about 15 of the approximately 5,400 lamps installed in Timberland stores have failed, equaling less than one percent.
Paying no upfront costs, the Bassett Home Furnishings showroom in Fife, Wash., recently completed an Energy Star-rated LED lighting project, aimed at improving light quality and energy efficiency.
Installed by Lime Energy, Bassett received a substantial utility incentive from Tacoma Power and will pay for the balance of the installation over time. Scott Selden, owner of the store, expects monthly energy costs to decrease by more than the monthly payment to Lime Energy for the next three years.
The LED retrofit project also is expected to eliminate 311,000 pounds of carbon dioxide, 1,217 pounds of sulfur dioxide and 772 pounds of nitrogen oxides (NOx).

U.S. Foodservice Completing LED Retrofit
As reported in Environmental Leader
U.S. Foodservice is completing a lighting retrofit project, deploying Orion’s LED technology and intelligent occupancy sensors in freezers at five of its facilities.
U.S. Foodservice will replace 400-watt High Intensity Discharge (HID) fixtures with 150-watt Orion LED fixtures. The actual number of new fixtures installed will be 15% less than what is currently installed. The reduction in watts consumed is expected to decrease the amount of electricity the food-service distributor uses in its freezers by 1.5 million kilowatt-hours a year, while at the same time increase light levels by 30%.
U.S. Foodservice began deploying Orion technology in 2009. To date, the company is reducing its energy consumption for lighting by 30-million kilowatt-hours and saving $3.3-million per year. As a result, U.S. Foodservice will reduce 19,076 tons of greenhouse gasses annually including carbon dioxide, sulfur dioxide, nitrogen oxides and mercury.

University of Kentucky Saving Energy With LED Lighting Retrofit
As reported in Environmental Leader
The University of Kentucky has released details of an energy savings performance contract it signed with Ameresco and on what it will save after the yearlong, energy-savings retrofit of 61 campus buildings, totaling 5.2 million square feet.The overall project is funded by UK-issued bonds valued at $25 million and will produce anticipated annual savings of $2,430,000. UK says these annual savings will more than pay the annual debt service on the bonds. Year one is a small positive savings over and above debt service. More savings take place over the next 12 years as the university’s energy rates increase.
Efficiency improvements will include lighting upgrades, water conservation, insulation, upgraded boilers, steam system improvements, domestic solar water heating, and HVAC system replacements. Along with the efficiency improvements to the buildings, the project will feature an energy education and awareness program for students, university faculty and staff.
When the project is completed next November, UK will have a smaller carbon footprint – an annual emissions reduction of about 23,291 tons of CO2. In addition, about 13,987,779 kilowatt hours and 37,673,020 gallons of water will be saved.
Under Kentucky Revised Statute 56.774, that covers energy savings performance contracting, energy service companies guarantee that utility savings generated by facility upgrades are sufficient to pay back the capital investment over a set period (generally 11 to 12 years). If the project does not provide these returns on the investment, the ESCO is responsible for the difference.
