As reported in Environmental Leader
Maines Paper & Food has cut its lighting-related energy use by 87 percent thanks to the installation of Digital Lumens’ Intelligent Lighting System in its 460,000-square-foot headquarters in Conklin, New York. The lighting retrofit also improves lighting levels and helps the company meets is corporate sustainability targets.With the lighting retrofit, Maines expects to save 1,726,108 kWh of electricity per year and prevent 1,240 metric tons of CO2 emissions.
After an evaluation of lighting alternatives including fluorescents and LEDs with the help of its energy-efficiency partner Groom Energy Solutions, Maines selected the Digital Lumens solution, which combines LED lighting fixtures, networking and software, as a one-for-one retrofit of highbay warehouse lights.
Maines can track energy usage and occupancy on a fixture-by-fixture basis, enabling them to fine tune the light retrofit program to maximize efficiency. The system also creates a lighting network inside the facility, which provides opportunities for future capabilities and/or measuring and monitoring other aspects of the facility, says the company.Groom Energy installed the lighting upgrade project and replaced Maines’ existing 400-watt, high-pressure sodium fixtures, reducing both energy use and ongoing maintenance.
“Lighting represents about 20 percent of our warehouse electricity costs, and a great opportunity to reduce our facilities’ costs and improve operational efficiency,” said Pat DeOrdio, vice president of operations, Maines Paper & Food Service, Inc.
“We evaluated the Digital Lumens Intelligent Lighting System and found that it enables us to significantly reduce our energy consumption, improve overall safety by increasing light levels and decrease maintenance. This solution delivers numerous operational and environmental benefits, and positions us to better serve our customers’ needs,” he added.
The New York State Energy Research and Development Authority (NYSERDA) provided the project incentive. NYSERDA’s goal is to help New York reduce energy consumption, promote the use of renewable energy sources and protect the environment.
Other recent projects that NYSERDA has provided funding or incentives for include recent HVAC upgrades at six New York State commercial facilities, which together will cut their energy consumption by more than 9.9 million kWH annually, a new energy-efficient grocery store, and a medical center.

DHL Launches Lightng Retrofit Program
DHL has launched a Lighting Retrofit Program at its Global Forwarding unit in the Americas region to help the company improve CO2 efficiency five percent by the end of 2010. The program will initially be rolled out in the United States before expanding to Canada and Mexico.
As part of Deutsche Post DHL and its GoGreen climate protection program, DHL Global Forwarding has committed to improving its CO2 efficiency by 30 percent by 2020 with an interim target of five percent by the end of this year. Deutsche Post DHL says it is the first logistics company in its industry to set a quantifiable environmental sustainability target.
The rollout will start at its Philadelphia, Pennsylvania, operation followed by Atlanta, Georgia; Dallas, Texas; and Miami, Florida. The San Juan, Puerto Rico operations is also planned in the initial rollout before expanding into Canada and Mexico where assessments are already under way.
By the end of the year, DHL Global Forwarding expects to achieve five percent CO2 efficiency improvements in the United States and Puerto Rico, together with a utility cost reduction of 50 percent and a projected CO2 reduction of 52 percent.
“Implementing a lighting retrofit program in our operations in the Americas, is one of the ways DHL Global Forwarding helps to protect the environment — and optimize operational costs,” said Sonia Nuñez, Head of GoGreen for DHL Global Forwarding, Americas.
DHL Global Forwarding operations in Houston, Texas; Chicago, Illinois; and Los Angeles, California already have efficient lighting.
In February 2008, the Toronto, Ontario facility in Canada was built with energy-efficient features. The advanced lighting system installed in the new facility is expected to deliver a 73 percent reduction in energy consumption for lighting.
DHL was one of three expedited shippers named by Inbound Logistics magazine on its list of “50 Green Supply Chain Partners.”

As many as fourteen Chicago buildings are about to install new energy efficiency measures as the result of a $25 million investment by South Korea, according to a report in the Chicago Tribune.
According to the report, the technology will significantly lower the buildings energy bills by lowering water temperature and turning lights off when they are not be used.
The technology will also allow the buildings to communicate with power suppliers, allowing them to reduce power demand during peak hours.
The projects themselves will cost $10 – $20 million, with the balance of the investment being directed toward research at Illinois universities.
The Tribune cited the Buildings Owners and Managers Association of Chicago as saying that if the technology were expanded to include all of downtown, the city would save enough electricity to be able to shut down a coal-fired power plant.
The project will also potentially include large residential buildings as well, according to the report. The Aon Center, an 83-floor skyscraper, is the only building who’s participation has been announced so far. According to the report, buildings will be chosen with an eye toward how much retrofitting they would need to make the new efficiency measures work.
Commercial buildings generate up to 40 percent of the nation’s greenhouse gas emissions. A report by Pike Research released this week said that retrofitting the country’s commercial building supply could save building owners and operators as much as a combined $41.1 billion.
One skyscraper in Los Angeles recently announced it is saving $160,000 annually after retrofitting its light fixtures to more efficient models.

UPS has set a new target to improve the miles per gallon (mpg) performance of its entire U.S. package delivery fleet by 20 percent between 2000 and 2020, according to the company’s latest corporate sustainability report.
In 2009, UPS drivers logged 77.3 million more miles than in 2000, yet fuel consumption decreased by 3.2 million gallons. UPS says fuel efficiency levels were improved through vehicle technology, vehicle maintenance procedures, fuel conservation efforts, sophisticated routing technology and operational initiatives such as minimizing engine idling. Alternative fuel technology and vehicle deployments also helped improve UPS’s fuel efficiency.
In April, UPS expanded its fleet of alternative-fuel vehicles with the deployment of 200 next-generation hybrid electric delivery trucks in Austin, Houston, Philadelphia, Chicago, Washington D.C., New York City, Minneapolis and Louisville.
This followed UPS’s deployment in January of 245 new delivery trucks fueled with compressed natural gas in Colorado and California, adding to a fleet of nearly 2,000 alternative fuel vehicles.
The fuel efficiency goal complements UPS’s announcement last year that it will improve the carbon efficiency (CO2/ATM) of its airline by an additional 20 percent by 2020, for a cumulative reduction of 42 percent since 1990. The airline represents 53 percent of the company’s global carbon footprint.
In 2007, UPS set a goal of reducing fuel consumption for its airline to 6.9 gals/100 ATM in 2011, representing a 32 percent improvement from a 1990 baseline. The company already has reached that goal, cutting aviation fuel use to 6.63 gals/100 ATM in 2009, and set a new goal of 6.57 for 2012.
Other environmental highlights in 2009 include becoming the first major global package carrier to offer a carbon neutral service for deliveries in the U.S. UPS announced its carbon neutral shipping program in 2009, and expanded it to include 35 nations in July.
UPS also was one of 11 members of the Air Transportation Association of America to sign deals with two potential aviation biofuel developers in 2009.
UPS also began reporting on greenhouse gas emissions in greater detail, including information on global CO2e emissions for Scope 1 and 2 for the first time and capturing and reporting more Scope 3 data from more sources.
Emissions for 2007 and 2008 are now stated at a higher level than in its 2008 report, due to UPS’s efforts to gather more comprehensive energy and emissions data even for past periods.
UPS reports that its direct (Scope 1) emissions declined in 2009 compared to 2008, in part because the recession reduced its delivery volume and package weight and changed its business mix. The company also implemented carbon avoidance strategies including modal shifting to help control emissions.
However, UPS’s indirect (Scope 2 and 3) emissions rose compared to 2008, due primarily to capturing more raw Scope 3 data from more sources and continuing to improve its analytical processes for quantifying reportable emissions.
UPS reports that its international package segment reduced Scope 1 and 2 CO2 emissions by 11 percent and its U.S. domestic package segment reduced Scope 1 and 2 CO2e absolute emissions by 6.2 percent in 2009, compared to 2008.
In 2009, energy efficiency for its largest business segment, U.S. Domestic Package, improved compared to the previous year, due to more efficient management of its ground and air fleets as well as it facilities and other assets.
Energy consumption was 3.5 percent lower per 1000 packages, and rose 3.6 percent per dollar of revenue. CO2e emissions declined 3.1 percent per 1000 packages, and increased 3.8 percent per dollar of revenue, according to the report.
Energy-efficient measures implemented by UPS to help cut its energy use include lighting retrofits and building automation system installations.
As an example, in 2009, UPS’s multi-year lighting upgrade program replaced or upgraded 22,683 fixtures. The total since 2007 is more than 69,000 fixtures upgraded, with an estimated annual energy savings of 25 million kilowatt hours.
UPS also is investing in renewable energy. In 2009, the company completed its test of a first-generation solid oxide fuel cell developed by Bloom Energy at its Anchorage, Alaska distribution facility. The fuel cell produced more than 300,000 kilowatt hours of electricity in 2009, and reduced CO2 emissions associated with the facility by 170 metric tonnes.
The company’s solar-powered facility in Palm Springs, Calif. produced 70 percent of its own electricity from solar technology, eliminating 500 metric tonnes of CO2 emissions.

Instituting a 10-year retrofit program for the country’s commercial spaces could save $41.1 billion in energy expenses every year, according to a new report by Pike Research.
According to the report, as of 2010, more than 80 percent of commercial buildings in the U.S. were more than 10 years old. Pike estimated that a 10-year retrofit program would cost a total of $22.5 billion over its 10-year span.
Commercial buildings cover a total of 79 billion square feet and are one of the leading sources of energy consumption and carbon emissions, according to the report.
However, despite these promising numbers, Pike Research’s analysis found that the actual market for energy efficiency retrofits is only a small fraction of the potential.
The best-funded opportunities for retrofits today are major upgrades in institutional buildings, especially in federal buildings. This market, already strong because of federal policy mandates and creditworthiness, received a boost from the American Recovery and Reinvestment Act (ARRA).
However, federal non-industrial buildings comprise less than 3 percent of existing commercial space, and the largest untapped potential is for energy retrofits in private commercial buildings.
Pike Research anticipates that several key market barriers will be successfully overcome during the next few years, and the firm expects that the private retrofit sector will experience strong growth through 2014 and beyond.
Several drivers are expanding the potential market for energy efficiency retrofits in commercial buildings, which can provide energy savings from 10 percent to more than 50 percent.
In addition to cost savings, energy retrofits are attractive for purposes of greenhouse gas (GHG) reductions, energy independence, green branding, property valuation, and productivity. However, the actual market is small compared to its potential, due to an assortment of barriers within various industry segments.
Kohl’s said it recently reduced its energy costs by $50 million by instituting energy efficiency measures in its stores. San Jose State, meanwhile, said it is saving $300,000 a year after retrofitting its lighting systems to more efficient fixtures.

The Naval Base Ventura County (NBVC) California is saving nearly $60,000 annually on the base’s energy bill thanks to lighting retrofits at two separate sites. The Port Hueneme and Point Mugu sites have replaced 1,178 existing roadway, area, and parking lot lighting fixtures with ultra-efficient LED luminaires manufactured by Lighting Science Group.
The entire project at the two bases will reduce their energy consumption by 440,000 kWH, cutting CO2 emissions by 316 metric tons and their annual utility bill by about $57,000, based on the average Ventura County, California, utility rate of 13.5 cents/kWh.
Considered one of the largest Navy lighting retrofits, the new LED fixtures are expected to deliver a 50 percent energy savings for more than a decade. The sites replaced existing high-pressure sodium cobra head street lighting fixtures throughout the residential areas with 430 PROLIFIC series Roadway luminaries that provide nearly 92 lumens per watt.
In addition, 549 WallPack luminaires were installed at the bachelor housing facilities, which illuminate exterior walkways and provide perimeter and security lighting. The luminaires will last up to three times longer and will consume less than half the amount of energy than conventional light fixtures and light sources.
To save additional energy, each fixture contains an occupancy sensor that reduces fixture wattage and light output from 35 to ten watts, when it senses inactivity after a set period of time.
The project also replaced traditional parking and general area lighting fixtures with 105 ShoeBox luminaires that use only 86 watts per fixture.
Navy ships also are converting to LED lighting to reduce electricity use. A study released last year shows that Navy ships could save 87 percent of the electricity used on existing lighting systems by converting to LED and HID lighting systems.

LED Lighting has been around for a long time now, however until recently it was not considered to be a good source of light for white light. Recent developments in technology has made it possible for an LED light to give as much white light as a conventional light bulb therefore making it a viable source of lighting for many different types of applications. Light Emitting Diodes are currently seeing heavy use in automotive lights.
LED is short for Light Emitting Diode. This type of lighting is semiconductor powered and with recent developments in technology is capable of emitting as much light as a regular light bulb without the energy loss in the form of heat. This type of lighting is more energy efficient and will outlast any regular light bulb available in the market place today. California which is always the countries front runner on energy saving and environmental protection laws is in the process of passing and impending ban on all incandescent light bulbs by 2010, this alone stands as a testament that LED lighting can be used in all aspects of daily life as a viable alternative to the incandescent light bulb.
Lets Look at the differences between Light Emitting Diodes and other conventional lighting available today:
First we have old faithful Incandescent lights which create light by running a current through a thin filament which heats it to a high enough temperature therefore producing visible light. This process is highly inefficient because 98 percent of the energy used to create light using this process is lost in the form of heat. The typical life span of an Incandescent light is about 1000 hours.
Fluorescent lamps work by passing a current thru a mercury vapor, which in turn produces ultra violet light, which is then absorbed inside the light by a phosphorous coating which will begin to glow. This process is more efficient then the incandescent light, however energy is lost by creating the ultra violet light which is then absorbed by the coating to give off the light. In addition the mercury vapor can be dangerous to your health if the lamp breaks. Fluorescent lamps have a much longer lifespan then the incandescent’s do. The lifespan of a fluorescent light is about 10,000 hours.
Now lets get to the LED Light. This lighting achieves its illumination by clustering Light Emitting Diodes in an orderly fashion, thereby creating a unified beam. This cluster can consist of many white LED’s or a mixed group of colored LED’s which when grouped together give off white light. The advantages of Light Emitting Diodes are:
No Tube or filament to break
Light Emitting Diodes have a longer lifespan than incandescent and fluorescent lights
Power consumption is lower then any of the others
Due to their small size they can be sued in many different types of lighting applications.
Very little energy is lost to heat.
LED lighting emits more light per unit of current then most of today’s conventional lighting therefore making it the number one choice for energy saving light available. Energy bills can be reduced by up to 30 percent by switching over to this light source. Due to their construction Light Emitting Diodes are very durable they generally last 100 times longer then conventional lighting products. Since this type of lighting does not emit heat it poses little to no danger in the form of contributing to causing a fire. The longevity of this type of lighting is hard to surpass. Generally LED lights will last up to 50 thousand hours, which gives them a life expecting of around 10 years before they need to be replaced.
Many forms of LED lighting are now available for every aspect of daily life. LED light bulbs are being used in flashlights, residential lighting, automotive as well as landscape lighting. More and more signs are also utilizing this light source. If you have looked at a stoplight really closely you will have seen a led light in action. Light Emitting Diodes are also breaking in to the arena of rope lighting, boat lights, and floodlights. Christmas tree lights are now also going to LED’s because of its many benefits not to mention that due to the fact that these lights do not give off large amounts of heat they are much safer to use on a Christmas tree then conventional Christmas tree lights
