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.

Value Energy Solutions Selected By Lanier Parking for Parking Garage Lighting Retrofit
Value Energy Solutions, one of the largest lighting installation and lighting retrofit companies in the nation, recently completed a large lighting retrofit project for AT &T at in the Lindbergh Center located in the prestigious Buckhead Office market. Lindbergh Center, the first transit-oriented mixed use development in Atlanta, features two fourteen story office towers that are adjacent to the Lindbergh MARTA Station. The Lindbergh Center parking decks are managed by Atlanta based, Lanier Parking Solutions, the largest parking management company in the Southeast.
Lanier Parking contacted Value Energy Solutions to determine what energy savings they could achieve by replacing and updating the lighting in their two enclosed parking decks. Value Energy Solutions completed a thorough analysis of the existing parking deck lighting and AT&T’s energy saving goals Value Energy Solutions recommended retrofitting the parking decks with over one eleven hundred 2-Lamp T-5 54wHO (high output) Vapor Tight Fluorescent lights. Lanier Parking selected a 40,000 hour (extended life) rated lamp to maximize their energy savings and reduce lighting maintenance costs.
AT&T has made energy savings and sustainability a significant corporate priority. They have established an Energy Scorecard to benchmark energy savings at all of their major facilities. A major focus of these facility improvements has been upgrading lighting and HVAC systems. The estimated energy savings from the Lindbergh Center lighting retrofit is an impressive 43% and the cost of the lighting upgrade will pay for itself in less than three years with an ROI of 34%.
Value Energy Solutions and Lanier Parking considered numerous relighting options and discovered the best lighting retrofit solutionwas using new fluorescent lighting technology. The Vapor Tight Reflector Series Linear Fluorescent fixtures used in the Lindbergh Center retrofit is the pinnacle of Vapor Tight Luminaries. They utilize T-5 lamping which provides better energy efficiency and equal or superior lumen output.

Furniture Row Undergoes LED Lighting Retrofit
As reported in Chain Store Age website
The Furniture Row Cos., one of the nation’s largest family-owned specialty home furnishings and bedding retailers, is installing LED lighting throughout its 330 Sofa Mart Oak Express, Bedroom Expressions and Denver Mattress Co. stores across the United States.
To date, the company has installed nearly 13,000 LED spotlights (from Cree) in its stores, out of more than 80,000 planned. The 11-watt Cree LED lights are replacing energy-wasting 90-watt halogen bulbs.
“We knew we wanted new lighting that addressed our goal of being environmental stewards, but we also wanted to remain fiscally responsible,” said Rod Schnurr, store planning coordinator, Furniture Row, Denver Col. “We also knew that we couldn’t sacrifice the high quality of light needed to accentuate the wood grains and highlight the beauty of the fabrics -- that’s what these Cree lights do.”

A good practice for businesses looking to reduce energy expenses is to consider an LED lighting retrofit. Lighting retrofits replace lighting with newer technology such as LED linear lighting to save on energy costs and maintenance costs. Many building experts recommend a lighting retrofit as the first step to reducing energy costs. Redbird LED is an Atlanta based manufacturer and designer of Premium LED lights at value price points. For more information please visit their LED Retrofit website or call ( 678) 733-2473
The first Furniture Row location to install LED lights saved $4,200 on monthly energy costs compared to the original lighting, Schnurr said. In addition to reduced energy consumption for lighting, the LRP-38 spotlights generate much lower heat output thereby saving on air conditioning costs.
Furniture Row also anticipates significant maintenance savings given the much longer service life of the LED lights, which are designed for a 50,000-hour lifetime in open applications. Prior to the LED lighting retrofit, store employees spent an estimated 15 hours per week replacing burned out halogen bulbs.

Harvard University Finds Smart Way To Save Energy is Parking Garage Lighting Retrofit
From the Harvard University Sustainability website
During the summer of 2009, Transportation Services installed energy efficient lighting fixtures and sensors within 10 University parking garages and at the Fleet Management facility at 155 North Harvard Street. The project is expected to conserve significant amounts of electricity and save approximately $400K a year.
The standard metal-halide lights, which use 198-watts per hour, are being replaced with 3-bulb/2-ballast super T8 fluorescent fixtures which use just 92-watts per hour – a reduction of more than 50%. Even though these parking garage lighting fixtures consume less energy, they provide the same amount of light. Motion sensors will further reduce energy use by turning off certain lights in areas where there has not been any activity for ten minutes. However the parking garages will never go completely dark. An extensive amount of research was conducted to ensure that there will always be sufficient lighting levels at all times.
Funded through the Office for Sustainability Loan Fund and a $200K rebate from NStar, the project is expected to pay for itself in approximately three years.

Forbes Reports on Colleges and Universities Energy Saving Efforts
As reported in Forbes magazine
Dickinson College in Carlisle, Pa., has pledged to be completely carbon-neutral by 2020. Overlooking Monterey Bay on the West Coast, the University of California-Santa Cruz saves an estimated 300,000 on water each year by eliminating trays in its dining halls. And in the Deep South, the University of Georgia, which subsidizes public transportation on campus, now has nearly 30 student organizations related to sustainability.
These schools all make our annual list of America's Greenest Colleges and Universities, and if they're any indication, environmentalism is booming on campuses nationwide. Among the reasons: money. By investing in energy-efficiency measures, schools can save millions of dollars over the long haul. For example, Harvard University, which also makes our list, last year installed energy-efficient lighting in its parking garages. It's expected to save the school an estimated $400,000 per year on its electric bill, according to the Sustainable Endowments Institute (SEI).
Each year since 2006 the institute has released a College Sustainability Report Card, grading more than 300 institutions (this year) on a range of green efforts, including student involvement, transportation and green building policies, investment priorities, food and recycling programs, and the administration's overall approach to sustainability. This year seven schools received A grades: Brown University, Dickinson, the University of Minnesota, Oberlin College, Pomona College, the University of Wisconsin-Madison and Yale. Another 45 earned a A-minuses.
"It's really impressive how far a large portion of higher education has come in the last four years," says Mark Orlowski, SEI's founder and executive director. He says in many cases students have been a driving force behind a school's green tide. Conversely, schools are increasingly aware that if they want to attract the best students, they need to show a commitment to sustainability.
In compiling our own list of greenest colleges, we've used the SEI's report card as a starting point, but we've also taken other factors into account. Does the Princeton Review also include a school on its elite Green Honor Roll? Does the Environmental Protection Agency recognize the institution as one of its top collegiate purchasers of green power? Is a school tracking its own efforts at environmental stewardship through a program run by the Association for the Advancement of Sustainability in Higher Education? Has it signed on to the Presidents' Climate Commitment to achieve net neutrality in greenhouse gas emissions? Is environmentalism a theme of its academics?
For example, for the last 39 years Northland College in Ashland, Wis., has given its liberal arts curriculum an environmental twist. Students can enroll in courses of study focused on sustainable agriculture, man's connections with nature, or the Lake Superior watershed (which includes a one-month trip around the watershed itself). Maine's Unity College, which bills itself as "America's Environmental College," offers green-study programs such as Conservation Law Enforcement and Environmental Writing. Both schools make use of renewable power sources to feed their electricity needs.
Schools get high marks for energy efficiency and green building standards. Some institutions, including Yale and the University of Minnesota, have their own co-generation power facilities, which produce both heat and electricity. Oberlin College in Ohio and Boston's Northeastern University are among many schools that require all new buildings meet at least LEED silver standards (a level of green certification established by the U.S. Green Building Council). Oberlin has also committed to becoming carbon-neutral by 2025. Two years ago Northeastern replaced nearly 70,000 light bulbs on campus with more energy-efficient options in an effort to save $1.2 million over six years.

Schools Green Their Building With Lighting Retrofits
Ten years ago, making a school "green" meant turning off unnecessary lights and carefully recycling trash.
While the basics are still important, today a green school could include geothermal heat exchangers and solar energy, strategies that used to be too expensive to consider.
The environmental pluses of green technology long have been recognized, said Mike Walsh, deputy secretary for administration at the state Department of Education.
But now he said, "In these tough economic times, there is becoming more of an economic argument to do this."
With improvements in quality, price and incentives, there's a greater opportunity for energy savings to offset the costs of technology.
"Solar panels cost less than they did five or 10 years ago. You see a better return," said Mr. Walsh. "Geothermal is an emerging area of renewable energy. It costs less than it did five years ago. People are thinking about wind. They weren't thinking about it five or 10 years ago."
Grants and other incentives also contribute to making technology more affordable. Over the past year, millions of dollars of government grants and incentives for renewable energy and other green measures have helped to make more options affordable.
A Pennsylvania Energy Development Authority grant covered nearly half of the $515,861 cost to install exterior LED lighting in 10 locations in the Pittsburgh Public Schools district.
The grant lowered the payback time -- the time in which the savings would cover the cost -- from 12.6 years to 6.5 years. The new lighting, nearly completed, is expected to save $40,881 a year.
Carlisle Area School District in Cumberland County got enough grants -- including $1 million from the federal economic stimulus, $950,000 from the state and $500,000 from its local electric company -- to pay for more than half of the $4.8 million cost to build the largest solar array of any public school district in the state.
The array, which includes four types of solar technology and covers 6.2 acres, was dedicated last month. The system will be an integral part of the curriculum, with students evaluating how well each type works.
The project is expected to pay for itself in 41/2 years by saving $150,000 a year in utility bills and by selling renewable energy credits to utility companies for nearly $500,000 a year, said Tom Longnecker, director of finance for Carlisle Area.
Two competitive federal school bond programs -- totaling $602 million statewide -- that underwrite interest made energy efficiency a top criterion for consideration in Pennsylvania.
The grants and incentives are intended at least in part to show others what is possible and to increase demand for green products.
Maureen Guttman, executive director of the Governor's Green Government Council, said she thinks the reasons for using green technology are even more compelling for schools than for the private sector.
"We really do have the data to show that the operating costs are significantly lower, and every school district we know is hurting for dollars," she said. "It's just the mindset of an initial capital investment which then has a long-term payoff."
Beyond the energy savings, Chris Berdnik, chief financial/chief operations officer for Pittsburgh Public Schools, said green buildings have the potential to increase academic performance.
"There's a significant amount of research that kids learn best when there's good natural classroom light and excellent indoor air quality," said Mr. Berdnik.
A group of state agencies has formed Pathways to Green Schools and named Pittsburgh and Norristown as pilot school districts. As such, they will receive technical assistance.
At the end of this school year, Pittsburgh plans to start a $14 million renovation of Pittsburgh Northview PreK-8 that will include green technology that will reduce the building's energy usage by about 45 percent.
One of the most unusual features at Northview is the use of a geothermal heating and cooling system.
No other K-12 school district in Allegheny County has installed a geothermal system, and only a handful of school districts across the state are doing or have done so, said Mr. Walsh.
Pittsburgh also plans to include a geothermal system in a renovation of Pittsburgh Arlington PreK-8 and is considering geothermal for Pittsburgh Oliver High School.
The geothermal systems that schools use in Pennsylvania do not typically generate electricity but instead use the temperature deep in the ground to help heat or cool a building.
A geothermal heat pump -- or ground source heat pump -- pumps heat from the ground in cold weather via water in a closed loop system and from the school to the ground in hot weather.
At Northview, the school's large parking lot will be torn up -- with the asphalt saved for reuse when the lot is restored -- and 60 wells will be drilled, each about six inches in diameter, 500 feet deep and 20 feet apart. They will be connected underground by water-filled pipes in a closed loop.
The heat exchange will take place in a mechanical house built on the parking lot.
Inside the school, each classroom will be able to control its own ventilator, which will have water-filled coils that heat or cool the room. The ventilators also will add fresh air from outside.
With the Northview project, the school district will seek its first LEED -- Leadership in Energy and Environmental Design -- certification.
The geothermal system is just one of a long list of green improvements that will be used to seek the rating at Northview.
Other improvements will include:
• New large windows with thermal panes tailored for northern or southern exposures
• Classroom overhead lights that automatically turn off in portions of the room where there is enough daylight
• A new roof will be well-insulated and a reflective white.
• Water will be collected from a roof to provide "gray water" for some of the toilets and urinals
• Two solar panels will be installed on a roof so science classes can study their energy production. A garden and a green wall -- a wall covered with plants -- will provide other educational opportunities
Other city schools also are getting various elements of green technology.
"In all of our projects when we design, we've always incorporated green," said Vidyahar Patil, director of facilities/plant operations.
Some other local K-12 school buildings have earned various LEED certifications, including Our Lady of the Sacred Heart High School in Coraopolis, Rowe Hall at Shady Side Academy and Wilson Elementary School in the Albert Gallatin School District.
A few others have Energy Star certifications for their conservation efforts, including Jeannette Senior High School and six buildings in the Hempfield Area School District.
Maximizing the benefits of green technology requires changing habits and making it part of the educational program, officials say.
On a tour of Northview, school officials noted an unused computer monitor left on, wasting electricity. Daylight was diminished because classroom blinds were pulled down and used as display space for children's work.
The Pittsburgh district has a labor-management energy committee as well as a group including students, employees and community members to help save energy.
Northview's design includes educational kiosks and exposed pipes so that students -- and staff -- will understand how their building works.
Carla Worthington, project manager and an architect with Renaissance 3 Architects, said the project will be a "great educational tool for the children and for the public."

Walmart in Puerto Rico Saves Money on Parking Deck Lighting Retrofit
In San Juan, Puerto Rico, Walmart is expected to save up to 48 percent of the electricity traditionally required to light its parking lots by retrofitting their lighting to LED Lights. They will also save an estimated 75 percent on maintenance costs.
On average, nearly one-third of a Walmart store’s energy consumption is tied to lighting. In addition to substantial energy and maintenance cost savings, the new LED parking lot lighting significantly reduces the greenhouse gas emissions associated with Walmart Puerto Rico’s operations.
“In 2009 alone, Walmart Puerto Rico’s operational energy efficiency initiatives saved more than 8.0-million kWh, equivalent to USD $1.4 million*. A large portion of these energy-efficient initiatives are tied to the continuous lighting improvements that Walmart is working with GE to help us achieve,” says Charles Zimmerman, vice president of international design and construction for Walmart. “Our latest initiative in Puerto Rico turns a high cost area such as outdoor lighting into an energy efficiency bellwether not only for our company on a global scale, but for the industry as a whole. We know outdoor LED lighting represents a huge opportunity for retailers to make strides economically and environmentally.”

RPI Completes LED Retrofit in Campus Buildings
As reported in LEDS Magazine
The Smart Lighting Engineering Research Center (ERC) at Rensselaer Polytechnic Institute (RPI) has collaborated with campus officials to replace 119 incandescent bulbs with LED retrofit lamps in the 9-story George M. Low Center for Industrial Innovation (CII) building. The Smart Lighting ERC expects the investment in the solid-state lighting (SSL) retrofit to pay for itself within 12 to 16 months.
The LED bulbs cost $60 each compared to $4.50 for the conventional incandescent bulbs. The LED retrofit project replaced 50W incandescent bulbs with LED alternatives that dissipate only 8W. The LED alternative produces the equivalent light output of 65W incandescent bulbs resulting in “better, brighter light” according to Smart Lighting ERC Director Robert Karlicek who led the project.
The expected payback period is based on both energy and maintenance savings. The campus typically replaces incandescent bulbs every four months while the LED replacements are expected to last six years. Once the payback is achieved the Smart Lighting ERC expects annual savings of $5608.
“Initially, we’re trying to show the campus community how easy it is to make a very noticeable difference in terms of sustainability and reduced energy consumption,” said Karlicek. “We hope this is just the first step. If we replaced all of the old bulbs in the CII with LEDs, the annual savings could increase by a factor of five. Imagine the impact of doing this across the entire campus — or across the entire world.”
Long term, the Smart Lighting ERC is focused on greater savings than what can be achieved with retrofit lamps. “The LED bulbs that were installed are a great showcase for sustainability, but they’re not ‘smart’ technology,” Karlicek said.
“When we talk about ‘smart lighting,’ we’re looking forward to a new wave of solid-state lighting with applications that will transform the way society uses light, said Karlicek. “The vision for smart lighting that we’re working to realize is a holistic integration of advanced light sources, sensors, and adaptive control architectures that take full advantage of the amazing capabilities of light. The smart lighting we’re developing will be able to talk with networked electronics and sensors within a space, and automatically adjust the lighting parameters to provide the ideal illumination required for the task at hand.”
The Smart Lighting ERC is led by RPI with partners Boston University and the University of New Mexico within funding from the National Science Foundation, industry, and New York state.

Medical Facilities Benefit From LED Retrofit
UCSF Medical Center replaced some of its surgical lighting with LED fixtures, doctors and nurses no longer complain about the heat from the light fixtures when performing surgical procedures.
"Previously we had to chill the OR [operating room] to offset the heat generated by the old fixtures," UCSF Project Manager John Lewis explained. "The new LED lights do not radiate heat and the OR medical staff is comfortable at standard OR temperatures."
Quality of light is an important issue to adoption of any new lighting technology. Fluorescents were unable to replicate the incandescent bulb's soft and pleasing glow and disappointed both professional lighting designers and the cube dwellers who toiled under their unnatural glare. LED lights hark back to a more basic light source, the sun. The spectrum and color rendition come closest yet to natural daylight.

A good practice for businesses looking to reduce energy expenses is to consider an LED lighting retrofit. Lighting retrofits replace lighting with newer technology such as LED linear lighting to save on energy costs and maintenance costs. Many building experts recommend a lighting retrofit as the first step to reducing energy costs. Redbird LED is an Atlanta based manufacturer and designer of Premium LED lights at value price points.

An LED is a semiconductor that creates light by releasing energy from electrons. It is frequently referred to as "solid state" or "digital" lighting. Because LED fixtures generate light over an area using thousands of tiny light sources, the fixtures also provide a clear, shadow-free light field that is ideal for task work, whether an accountant, engineer or surgeon.
"The most important criteria for our application is the quality of light. After an early test, we eliminated fluorescent fixtures since fluorescents render colors poorly," Lewis said. "The medical team found the quality of light provided by the new LED lighting was superior to the existing incandescent lighting."

GE Saving Energy With Industrial Lighting Retrofit
Gov. Steve Beshear along with Energy and Environment Cabinet Secretary Len Peters and Economic Development Cabinet Secretary Larry Hayes visited General Electric’s (GE) Aviation Division in Madisonville to view the results of the company’s recent lighting retrofit investment project. GE Aviation was awarded $200,000 in American Recovery and Reinvestment Act (ARRA) funding to replace old, inefficient lighting with advanced energy efficient lighting fixtures.
“My Energy and Environment Cabinet and Economic Development Cabinet collaborated to secure federal stimulus dollars for several energy efficiency retrofitting projects at industrial facilities across our state,” said Gov. Beshear. “Projects like the one we celebrate today at GE Aviation are proof that these stimulus dollars are truly well spent, showing that when government works hand in hand with the private sector, big things can happen.”
GE Aviation was one of seven companies selected for a grant through a competitive Request for Proposal (RFP), which was administered by the Cabinet for Economic Development through a partnership with the Department for Energy Development and Independence. More than $4 million in total ARRA funds have been awarded to date through this initiative. The cabinet provides 50 percent of the funds needed to complete the lighting upgrades and each company provides the additional funding required to complete its project.
GE estimates that the lighting retrofit project will save the company $200,000 per year in utility costs, while providing better lighting in which to work and reducing the company’s carbon footprint.

“GE has a strong commitment to reduce greenhouse gas emissions and improve the energy efficiencies of our operations,” said David Groth, plant leader at GE Aviation’s Madisonville facility. “At the same time, our facility needs to ensure our investment decisions make economic sense. The ARRA funding made available through the state enabled our site to put this lighting retrofit project on the fast track and begin reducing our energy usage. The payback for both GE and the state is well worth the investment.”
The purpose of the grant funding is to accelerate energy efficiency and renewable energy industrial projects for businesses locating or expanding operations in Kentucky that create or retain jobs while saving energy and reducing carbon emissions. Additionally, the funding helps achieve the goals set by Gov. Steve Beshear’s Intelligent Energy Choices for Kentucky’s Future: Kentucky’s 7-Point Energy Strategy.

New Energy Efficient Lighting Reduces Energy Costs
As reported in Consulting Specifiying Magazine
Energy reduction in existing facilities can easily be achieved by replacing existing inefficient lighting products. Most commercial buildings built prior to 1990 typically are illuminated with T12 fluorescent, incandescent, high-pressure sodium (HPS), or metal halide lamps. These luminaires typically operate on inefficient magnetic ballasts when required by the lamp type. T12 fluorescent lamps are the only one of the four lamps mentioned above that is no longer viable, as they have been replaced with more energy-efficient T8 and T5 lamps.
Both T8 and T5 lamps produce substantially more lumens per W (approximately 100) than the T12 (approximately 60). One other advantage to the T5 and T8 lamps is their physical size. A T12 is 12/8ths of an inch, a T8 is 8/8ths, and a T5 is 5/8ths. There are advantages of this smaller lamp envelope; luminaires can be specifically designed around the lamp, allowing them to more easily control light distribution from the smaller source. This allows the luminaires to be more efficient at delivering the light to where it is intended. Simply replacing T12 fluorescent lamps with T8 or T5 can reduce the lighting load of a building by up to 40%.
Incandescent lamp and halogen lamps are slowly being phased out by energy legislation, but they still have several applications and therefore cannot be considered an antiquated lamp source like the T12. (Editor’s note: Suitable incandescent applications are not discussed here as they are not typically applicable to the majority of commercial buildings.) One location where incandescent is not practical anymore is for general illumination of commercial buildings. Removing incandescent luminaires and replacing them with the energy efficiency of T8, T5, or compact fluorescent lights (CFLs) can reduce consumption and maintenance costs dramatically. A typical 60 W A-lamp screw-in incandescent will produce only about 15 lumens/W versus the 100 noted above for T8 and T5.
In some cases, the incandescent lamps will need to be replaced by CFLs, which are not quite as efficient as linear T8 and T5 lamps but still produce about 60 lumens per W or four times that of an incandescent lamp. Use of LED luminaires also has gained significant steam over the past few years due to millions of dollars of federally funded research and advancement in the technology. LEDs can typically take the place of just about any incandescent lighting application and do it more effectively—and much more efficiently. While the future for LEDs is bright, how they are applied in retrofit applications should be carefully evaluated.
Commercial buildings primarily have metal halide and HPS lamps for large spaces such as lobbies, atriums, warehouses, and parking garages. Currently, both are viable solutions in many settings and can compare favorably to fluorescent in certain applications. One important aspect to consider is that metal halide lamps as they were five years ago (probe-start) are no longer available. Pulse-start metal halide technology improved on the efficiency of metal halide sources dramatically, and legislation such as the Energy Independence and Security Act of 2007 (EISA 2007) has all but outlawed standard metal halide lamps as they cannot meet the more stringent requirements.
Replacing old probe-start metal halide sources with newer pulse-start lamps can reduce energy consumption by up to 25%. To push these savings even further, electronic metal halide ballasts can be used to greatly reduce or eliminate energy loses in the ballast itself. HPS still has applications, but rarely inside commercial buildings due to its very poor color rendering (22 CRI) and warm color temperature (2100 K).
Warehouses, garages, and high-bay areas still have HPS lights. HPS is an efficient light source similar to metal halide but often is not perceived that way due to its “orange” color. When measuring light levels, HPS will produce light levels (measured by a photometer) similar to those of fluorescent and/or metal halide; however, they will not seem as bright. This is due to how the human eye functions at different wavelengths. The light produced by a HPS source is a longer wavelength (approximately 640 nm), which typically will be perceived by the rods in the human eye, and not the cones (which allow us to see color). This is referred to as scotopic vision, or night vision. When cones are not fully functional, such as under HPS lamp sources, objects seem to have no color or appear orange. While photometric measurements will be similar, some suggest that HPS lamp sources should have a reduction factor of up to 25% of this light output due to the poor color rendering and orange color temperature. This issue should be considered when retrofitting HPS spaces.

University of California, Davis Lighting Retrofit Includes LED Lighting
As reported in the September 2010 Issue of maintennace Solutions
Commercial and institutional facilities measure the success of building retrofits and upgrades in a variety of ways, including cost savings, reduced energy use, and improved productivity of those responsible for maintaining the new technology.
But one indicator that is difficult to quantify — yet speaks to the innovation and quality of the project — is the level of interest from peers outside the organization. A prime example of that dynamic is taking place at the University of California, Davis, where lighting retrofits are garnering a great deal of attention.
"It's been an interesting ride so far," says Chris Cioni, the university's associate director of utilities. "We've had a lot of inquiries from folks in the field who have found out about the projects just by searching on the Internet."
The university's Smart Lighting Initiative has turned the campus into something of a lighting laboratory, thanks in large part to the university's relationship with the California Lighting Technology Center (CLTC), a demonstration and education facility on campus that develops energy-efficient technologies. Cioni uses CLTC staff as a sounding board when considering cutting-edge lighting technology for lighting retrofit projects.
"That's where I rely pretty much on the CLTC," he says. "It's been fantastic having them here."

Focus on Energy, Safety
Cioni, his team, and the CLTC joined forces in retrofitting lighting fixtures in campus parking structures and surface lots. Their next set of projects will focus on pathways, roads, and fixtures on building exteriors. The opportunities for savings are great, considering the number of exterior fixtures on campus — 2,300 fixtures in parking structures and surface lots, as well as 700 fixtures on roads, 1,300 on pedestrian and bicycle paths, and 3,000 on building exteriors.
The Smart Lighting Initiative, which began in late 2004, does include interior lighting, but Cioni concentrates solely on exterior fixtures. The university spent almost $1 million retrofitting lighting fixtures in its surface lots and parking structures, which generated about $300,000 in utility rebates. The projects have resulted in additional benefits, including energy savings, reduced maintenance, and improved safety.
The primary technologies the university specified for the retrofits were bi-level induction lamps, light-emitting-diode (LED) fixtures, and lighting controls.
"The energy savings were the first target," Cioni says. "What drove me was having those very large and prominent parking lots right near a very visible part of campus. We have a big performing arts center (The Robert and Margrit Mondavi Center for the Performing Arts), and it's kind of a focal point. Seeing these empty parking lots when I would drive in early in the morning when it was still dark, it just caught me as wasteful and a real opportunity to do something different."
While lowering energy use was a primary goal, Cioni felt the projects needed to have benefits beyond energy savings to generate broad support. So he met with the campus police chief to discuss the retrofits' impact on public safety.
"There were perceived safety improvements by moving some of the lights — low-color temperature (fixtures) — to this whiter light," Cioni says of the bi-level induction lamps. "The patrol officers could see things more clearly and distinguish colors and details. The bi-level or adaptable-light mode, where it goes from a dormant, half output to full output based on occupancy (is important)."
Using the induction lamps also results in longer lamp life — up to 100,000 hours — which means less frequent replacement and fewer lamps in landfills.
