Atlanta's updated ordinance will benefit everyone.
In 2017, Atlanta City Council updated a city ordinance to include requiring LEED certification for new construction, as well as requiring existing buildings of less than 25,000 square feet to recertify to LEED standards once per decade. The new construction directive took effect immediately, but the LEED for Existing Buildings requirement will be phased in over 10 years. This change will not only foster greater energy efficiency in the city, but will also lead to a healthier environment for the community.

Starting with LEED standards
In 2003, Atlanta City Council approved their first-ever sustainable building guidelines, bringing environmental concern to the forefront of the city building design process. Originally, the guidelines required that all new construction, municipal buildings under 5,000 square feet, or involving major renovations, would be centered in the LEED Silver standard. However, merely meeting LEED Silver guidelines meant that city-owned buildings weren’t made to move through the formal certification process, so there was no way to collect data or evaluate performance.

Raising the bar to LEED certification
With Atlanta’s population at 6 million—and on track to grow 25 percent in the next 15 years—reassessing this policy to further sustainable growth was a key priority. By encouraging a building team to meet a standard rather than achieve certification, the city offered little incentive to participate and no enforcement.

Now, by embedding LEED certification into Atlanta’s green building ordinance, not only has a formal assessment been completed, but open-ended compliance also follows. The collection and analysis of performance data creates an opportunity for further energy and cost savings. On top of updating the ordinance to include LEED for New Construction, existing buildings of less than 25,000 square feet must recertify to LEED standards every 10 years under LEED Operations and Maintenance (LEED O+M).

Although USGBC Georgia believes it’s important to verify new construction performance goals with design, certifying existing buildings in the city will significantly reduce wasted energy. By phasing in the LEED O+M requirements, the city gains foresight for budget concerns and capital improvements on older buildings with greater energy demands. Once implemented, LEED O+M certification for Atlanta means proactive management for facilities management and smarter spending when prioritizing upgrades. Additionally, having a sophisticated understanding of a building’s assets leads to annually reduced operations expenses.

These changes will continue to push the market for further efficiency in the Southeast. Vision for effective change means working smarter for the city and taxpayers alike. As a rule, healthier buildings create an atmosphere for occupants to thrive in while also lessening environmental impact, giving the community a return on their investment.

LED Lighting Cuts Carbon Dioxide Emissions By Half a Billion Tons in 2017

LED lighting cuts carbon dioxide emissions by half a billion tons in 2017
The use of LEDs to illuminate buildings and outdoor spaces reduced the total carbon dioxide (CO2) emissions of lighting by an estimated 570 million tons in 2017 (equivalent to shutting down 162 coal-fired power plants), according to analyst firm IHS Markit. LED lighting uses an average of 40% less power than fluorescents, and 80% less than incandescents, to produce the same amount of light.

“The efficiency of LEDs is essentially what makes them environmentally friendly,” comments Jamie Fox, principal analyst, lighting & LEDs group. “Therefore, LED conversion is unlike other measures, which require people to reduce consumption or make lifestyle changes.”

LED component and lighting companies were responsible for reducing the global carbon (CO2e) footprint by an estimated 1.5% in 2017, and that is likely to continue to grow as more LEDs are installed worldwide, says IHS Markit.

Another environmental benefit is that LEDs have a longer life span than traditional bulbs and fewer are produced, so the emissions and pollution associated with the production, shipping, sale and disposal of the products is reduced. Secondly, unlike fluorescents, LEDs do not contain mercury. LEDs also decrease air pollution, since most electrical energy is still generated by burning fossil fuels. “While other activities affect climate change more than lighting does, it is still a very strong contribution from a single industry sector,” Fox says.



IHS Markit has tracked the market share for top LED component suppliers for many years. Based on an analysis of this data, Nichia can claim credit for having saved the most carbon overall — accounting for 10% of all LED lighting reduction achieved in 2017, which translates into 57 million tons of CO2 (about the same as 16 coal plants). Cree followed Nichia with 8%, while Lumileds, Seoul Semiconductor, MLS, Samsung and LG Innotek each have a share of 4-7%.

Savings achieved by each company relate to the energy saved by the use of its components while installed in lighting applications. It does not include a whole lifecycle analysis, which would likely lead to a small additional positive benefit, due to the longer life of LEDs.

“LED component companies and lighting companies have transformed their industry,” Fox comments. “They are fighting climate change much more effectively than other industries, and they should be given credit for it. Unlike in other industry sectors, workers at LED companies can honestly say that by selling more of their products, they are helping to reduce global warming.”

IHS Markit notes that its figures are only based on the lighting market. They do not include energy saved by LEDs that replaced other technologies in other sectors, such as automotive and consumer technology.

CFL Light Bulbs Are Dangerous When Broken

CFL Bulbs contain a small amount of mercury one of the most poisonous substances on earth.  Breaking them results in a hazardous material clean up.

Fluorescent light bulbs contain the toxic compound mercury, which could cause mercury poisoning in varying degrees if you handle broken bulbs without protection. According to the National Institutes of Health and the Environmental Protection Agency (EPA) some symptoms of mild exposure to mercury include, but are not limited to insomnia, headache, mood changes, muscle atrophy, irritability, diarrhea, vomiting, swollen gums, a metallic taste in your mouth and breathing difficulties If the condition is not treated, permanent lung or brain damage and kidney failure is possible.

Many light bulbs on the market contain elemental mercury. All HID light bulbs including metal halide and high-pressure sodium light bulbs contain certain levels of mercury. 250-watt metal halide and high-pressure sodium light bulbs contain around 38 mg and 15 mg of mercury.

All fluorescent light bulbs contain the toxic compound mercury. The amount of mercury present in your fluorescent light bulb is very small in most cases–some bulbs contain as little as 3.5 mg per bulb no matter what the wattage is.

NBC report of the dangers when a CFL bulb breaks because of it's mercury content.

DOE Report on Energy Reporting Capability of PoE Connected Lighting Systems

DOE Publishes Report on the Energy Reporting Capability of PoE Connected Lighting Systems

DOE has published the first part of a study to explore the energy reporting capability of commercially marketed Power over Ethernet (PoE) connected lighting systems. The new report provides a brief background on the development of the various PoE technologies, ranging from standards-based to proprietary, and illustrates the convergence of PoE power sourcing capabilities and LED luminaire power requirements. It then classifies PoE system devices in relationship to how they’re used in systems — introducing clarifying terminology as needed — and briefly describes different PoE system architectures implemented by various lighting manufacturers. A discussion of existing standards and specifications that address energy reporting is provided, and existing test setups and methods germane to characterizing PoE system energy reporting performance are reviewed.

Connected lighting systems that can report their own energy consumption can deliver increased energy savings over conventional lighting solutions by facilitating data-driven energy management. PoE technology — in which a single Ethernet cable is used to both provide low-voltage DC power and enable network communication — has the potential to bring this capability to mainstream lighting applications, and has become increasingly viable for LED lighting.

Atlanta Commits To 100 Percent Renewable Energy By 2035

Atlanta Commits To 100 Percent Renewable Energy By 2035
The city becomes the 27th in the U.S. to pledge to go totally green.
By Chris D’Angelo
WASHINGTON — Atlanta lawmakers approved a measure on Monday aimed at powering the city entirely on renewable energy sources, including solar and wind, by 2035.

A resolution introduced by city council member Kwanza Hall and unanimously approved commits city government to develop a plan for transitioning all of its buildings to clean electricity sources by 2025, and for the entire city to go green a decade later.

“We know that moving to clean energy will create good jobs, clean up our air and water and lower our residents’ utility bills,” Hall, who’s also a Democratic candidate for mayor, said in a statement. “We never thought we’d be away from landline phones or desktop computers, but today we carry our smart phones around and they’re more powerful than anything we used to have. We have to set an ambitious goal or we’re never going to get there.”

Atlanta becomes the 27th U.S. city and the first in Georgia to pledge a 100-percent renewable energy goal, according to the Sierra Club.

“Just days after hundreds of thousands marched for climate action across the globe, city leaders here in Atlanta are answering the call,” Terry said in a statement. “Today’s commitment will inspire bold, ambitious leadership from cities throughout the United States and pave the way for a healthier and stronger Atlanta.”

Monday’s vote comes less than a month after Hall came under fire for voicing skepticism about climate change.

“I got a question mark on the global warming thing,” he said at a forum last month, the Atlanta Journal-Constitution reported. “I do believe in sustainability. I’m a science-minded person and I have a science background. But stuff is in the media too much. … It’s hard for me to be convinced sometimes.”

One day after his controversial remark, Hall issued a press release spelling out his goal to make the city run on clean energy and clarifying his previous comment.

“I did not articulate where I am coming from clearly, at all,” he said. “I believe in science, and the overwhelming scientific consensus that tells us that our planet is warming and it is caused by humans burning fossil fuels. What I’m not sold on is the politicization of big issues like climate change. A lot of it is senseless propaganda, and it comes from both sides.”

Atlanta’s commitment follows a similar pledge by the city of South Lake Tahoe, California, last month.

From SSL Postings: All Fired Up About Down-Conversion

April 19, 2017
All Fired Up About Down-Conversion
As you probably know, the process of down-conversion by phosphors has been central to the development of white-emitting LEDs. That’s because, for most white-LED systems, the LED emits blue photons, most of which are converted to green-yellow and red by a layer of phosphors that typically rests on top of the LED, with the resulting color mix perceived as white by the human eye.

This process, by which photons are converted from more-energetic colors to less-energetic colors, is known as down-conversion. And while down-conversion phosphors have progressed considerably over the past decade, they still need significant improvements in order to meet the performance targets described in the DOE SSL R&D Plan. That’s especially true for red phosphors, which could benefit from being less thermally sensitive and having a narrower spectral width to better match the eye response. With DOE R&D support, GE has commercialized a promising narrow red phosphor, PFS, that’s making its way into GE lighting products with excellent color quality and efficacy. Another narrow red phosphor that has made it into LED products with similar benefits is the SLA phosphor developed by Lumileds.

However, phosphors aren’t the only materials that can be used as down-converters. For quite some time now, scientists — some of them funded by DOE — have been working on developing alternative down-conversion materials called quantum dots (QDs), which are more tunable than phosphors in terms of emitted wavelength, and can be spectrally purer (that is, they have a narrower spectral width). In addition, QDs have demonstrated very high conversion efficiencies that match or exceed those of existing phosphors.

QDs are engineered materials that convert light through a different process than do phosphors, which are limited by their own material emission and absorption properties, whereas QDs re-emit light as a function of their size. What’s more, the ability to develop specific sizes of QDs gives them the potential for greater spectral control. For the past few years, QDs have been used in TV displays, because their narrow emission expands the color gamut, resulting in a more vivid image. However, the rapid degradation of QDs under on-chip LED operating conditions — notably, high temperature, humidity, and blue-flux intensities — has been the biggest barrier to their use as a narrow-band red solution for white LEDs in general illumination applications.

That barrier appears to have been overcome — or, at least, to be toppling. Scientists at Lumileds, reporting in the journal Photonics Research, say they’ve used red QDs with tunable peak emission and narrow spectral width to demonstrate the first commercial production-ready white QD LEDs for the general illumination market. This has resulted, they say, in LED efficacy improvements of 5-15% over commercial phosphor-based LEDs, at CCTs that range from 2700K to 5000K — and without the degradation that plagued previous attempts.

In other words, up until now, no one had been able to successfully deploy QDs on chips, because of the degradation from the flux, temperature, and moisture. Lumileds has succeeded by using QDs that are developed by Pacific Light Technologies and are able to withstand the extreme environment of a conventional LED package, while showing similar stability as the phosphors that they’re displacing.

This is an important breakthrough, because it puts a whole new technology in the LED lighting toolbox, enabling higher luminous efficacy and even more-refined control of the emission spectrum for down-converted LEDs. DOE is currently funding an R&D project at Columbia University that aims to further improve the manufacturability of the QDs that were used to get this result, and Lumileds is planning to commercialize the breakthrough.

The development of quantum dots illustrates the importance not only of taking an integrated approach that considers all elements and requirements of the system, but also of casting a wide net for R&D that takes into account alternative approaches that can help improve SSL performance.

New CALiPER Snapshot on TLEDs

Linear fluorescent lamps — energy-efficient, long-lived, and relatively inexpensive — have been a staple of ambient lighting in offices, classrooms, and other commercial spaces, where they’re usually housed in troffers. Linear LED lamps, commonly known as TLEDs, typically draw about 60% of the power of linear fluorescents and have become a viable alternative, used mainly in retrofit situations. DOE’s CALiPER program has released a new Snapshot report on TLEDs that’s based on LED Lighting Facts® data.

Among the key findings:
• TLEDs now comprise more than 50% of all lamps listed with LED Lighting Facts, and more than 10% of all listed products.
• TLEDs offer the highest mean efficacy of any lamp type, and also include the listed product with the highest efficacy (190 lm/W).
• In aggregate, TLED efficacy decreases by 3 lm/W for every 1000K decrease in CCT.
• While the raw efficacy of TLEDs exceeds that of dedicated LED troffers, the reverse is true if TLED efficacy is adjusted to account for luminaire efficiency. In other words, dedicated LED troffers tend to exceed the efficacy of troffers fitted with TLEDs.
• Almost all (98%) of the listed TLEDs have a CRI in the 80s, with most between 80 and 85.
• A vast majority (97%) of TLEDs that are currently listed by LED Lighting Facts (and that report this optional metric) have a power factor of 0.90 or greater.
• Nearly 90% of the currently listed TLEDs (which include 2’- and 4’-long products) emit between 1,000 and 3,000 lumens. This is generally less than the emission of a typical 4’ linear fluorescent lamp. Of the more than two-thirds of TLED products that are identified as having a 4’ length, the mean output is 2,094 lumens.
As the numbers from LED Lighting Facts attest, TLEDs seem to be everywhere, and their numbers are growing rapidly. But while their rise to prominence is indisputable, they’re not necessarily a clear favorite when evaluating performance.

LED Lighting Facts data show that TLEDs consistently draw less power and emit fewer lumens than the linear fluorescent lamps they’re intended to replace. On balance, they have somewhat higher efficacies, but the energy savings achieved are in large part due to the lower power draw. Importantly, TLEDs offer more of a directional emission than linear fluorescent lamps, meaning they can make troffers or other luminaires more efficient, delivering equal illuminance to the work plane, with fewer lamp lumens. However, sometimes the increased luminaire efficiency can’t compensate for the reduced lamp lumens. In such cases, energy savings are derived from reducing the light levels, which may or may not be acceptable. The change in distribution, something that’s not obvious from the LED Lighting Facts data, presents yet another issue, as it can change both the appearance of the luminaire and the distribution of light within a space.

TLEDs are often compared to other LED options for replacing a fluorescent lighting system — such as using retrofit kits or dedicated LED fixtures. At first glance, TLEDs may appear to be superior, with higher efficacy and likely lower product and installation costs. But accounting for factors such as luminaire efficiency may tip the balance against TLEDs in some scenarios, and their long-term costs may be increased by factoring in the remaining life of existing fluorescent ballasts, if they’re to be reused.

Nevertheless, viable TLED options are increasingly available, which was not the case a few years ago. And as they push the efficacy limits for LED products, TLEDs can be compelling replacements for fluorescent tubes, as long as other tradeoffs are appropriately accounted for. But there are thousands of choices when specifying TLEDs. And as the new Snapshot report shows, there’s considerable diversity in performance, even when examining only basic attributes. The Snapshot doesn’t address the electrical and safety considerations when changing from fluorescent to LED lamps, nor does it examine features such as distribution of light or lifetime. It also doesn’t distinguish between the different types of TLEDs (UL Type A, those that can operate directly on a fluorescent ballast; UL Type B, those with an integrated driver; UL Type C, those with an external driver; and hybrids), because they don’t differ appreciably in photometric performance. Their distinguishing features, however, are very important considerations during specification and installation.

When evaluating TLEDs, it’s critical to examine the expected performance of the complete lamp and luminaire system, understand the complexities of installation, and be cautious in considering long-term performance.
