Nila Broadcast LEDs for NBA Tournament
Nila broadcast-‐quality smart LED luminaires were showcased at the NBA Development League tournament. The arena was lit exclusively with 115 tungsten-‐balanced Boxers, with a total power draw of 23,000 wa,s. That's in place of the usual load of 100,000 wa,s used by the tradiNonal fixtures at the previous year’s tournament – 77% savings. Nila’s luminaires are being used and assessed in the Staples arena to replace two exisNng lighNng systems (NBA and NHL). MulNple savings plus added benefits: energy, emissions, polluNon, lamp replacement, labor, color quality, lumen quanNty, visual acuity, instant restart.

an LED was not standardized, meaning that each vendor performed these calculation Unlike fluorescents, there are no ON/OFF cycling limitations for LED light sources, because frequent switching lifetime ratings claims that varied widely among vendors, does leadingnot to an unnecessary le impact the useful life of an LED. So, when LEDs are integrated industrial with occupancy and/or daylight harvesting sensors, and are consumers. cycled on and off more frequently, useable lifespan is being extended because they are being turned off when not needed.! The question then becomes: Can LED useful lifetime ratings be compared, on an apples-to-apples basis, to the lifetime ratings of incandescent lamps, which are based on MTBF? The short answer is yes. If incandescent lifetime ratings were

ESPC Basic Structure the capital cost of the upgrades will appear on the customer’s balance sheet. Investments that appear on a company’s balance sheet often face a more challenging internal approval process, even where an internal champion is supportive of the project. The energy efficiency investment is not likely central to the customer’s business and, from an accounting point of view, it’s better for the customer if treated as an expense kept off its balance sheet. As compared to the ESA and MESA models in which the monthly payments are simply off-balance sheet expenses, similarly sized monthly payments for debt service that are on the balance sheet will likely be treated with greater scrutiny. Legal Issues As part of its Dodd-Frank rulemaking process, the U.S. Securities and Exchange Commission (SEC) has proposed that ESCOs be required to register as "municipal financial advisors" and be subject to regulatory oversight as such. The ESCO industry, however, argues that ESCOs, like engineering firms, should be exempted from this new registration requirement. This debate is ongoing and has yet to be resolved. Overall Assessment

MESA Basic Structure
Sources of Financing The MESA project developer may finance a MESA project using the same strategies as the ESA developer described above, including the establishment of an SPE for each MESA project. MESA projects will attract lenders, however, who are generally willing and able to tolerate the risk on utility rates. Since the MESA project developer is responsible for utility payments, it carries the risk of utility rates increasing faster than predicted. As with the ESA structure, since energy efficiency improvements do not qualify for the ITC or PTC, unlike solar and wind-generation projects, tax equity investors are not a primary source of capital for energy efficiency projects.

Dragon-‐Shaped 100% Solar PV Stadium in Taiwan Designed by Toyo Ito, the dragon-‐shaped 50,000 seat arena is clad in 8,844 solar panels on 14,155 m2 roof.
It illuminates the track and field with 3,300 lux (lumens per m2). The Solar PV system provides 100% of the electricity during games, and surplus energy is sold during non-‐game periods.
Built upon a clear area of 19 hectares, nearly 7 hectares has been reserved for the development of integrated public green spaces, bike paths, sports parks, and an ecological pond.
The stadium also integrates addiNonal green features such as permeable pavements and the extensive use of reusable, local materials.

LED Ligh6ng Using Power over Ethernet (PoE) LED lighNng that uses Power over Ethernet (PoE) can be powered not by an electrical powerline but by basic Ethernet cable. The low-‐voltage Category 5 or Cat 6 cable can send both power and data to LEDs. And that can save on wiring costs as well. The LED light fixtures get an IP address, interact with networked sensors, devices, and mobile users, and become fully programmable. By connecNng lighNng directly to the Internet, controls can be driven by so€ware. And new apps will make lighNng a service. Building owners can achieve lower Total Cost of Ownership (TCO) including lower first costs, lower operaNng expense, and lower cost of space-‐reconfiguraNon. Energy savings go beyond the efficiency of the LED light source, to capture addiNonal savings through more universal and pervasive controls. For example, so€ware technology allows for across the board load shedding including Demand-‐Response (DR) capabiliNes required by some uNlity companies.

Power quality fundamentals • Power quality broadly describes the fitness of electric power delivered over networks to drive electric loads in a manner that allows the loads to function as intended without significant reduction in performance or lifetime • Power quality is a system characteristic, not a component characteristic. There are many ways in which electric power can be of poor quality and many more causes of such poor quality power. • Power quality can be degraded by displacement between voltage and current waveforms, and distortion of voltage or current waveforms • Displacement can be lagging or leading – Inductive loads (e.g. motors and magnetic transformers) cause lagging displacement – Capacitive loads (e.g. most SMPS and LED sources) cause leading displacement
• Voltage waveform distortions typically created by generators • Current waveform distortions typically created by loads Michael Poplawski, Pacific NW NaNonal Lab (PNNL), Power Quality Myths and MisconcepNons: What you need to know, LightFair Intl, June 2014 2
Power quality fundamentals • Power quality degredation typically results in higher RMS currents, and harmonic currents • Higher RMS currents – Lead to greater electricity transport (I2R) losses – Require greater wire, circuit breaker, transformer, etc. sizes
• Harmonic currents – Can degrade performance of electronic equipment – Can damage some electronic equipment – Some (odd multiples of three) matter more than others
• Phase-cut dimming controls degrade the power quality of any circuit they are operating on, regardless of the light source technology being controlled
Michael Poplawski, Pacific NW NaNonal Lab (PNNL), Power Quality Myths and MisconcepNons: What you need to know, LightFair Intl, June 2014
Power quality metrics • Common power quality metrics (e.g. power factor and THD) are useful but imperfect (not unlike CCT and CRI) – (True) power factor is a measure of displacement and distortion – THD is a measure of current (THD-I) or voltage (THD-V) distortion
• Proper use of power quality metrics requires an understanding of what they are attempting to characterize, and their limitations. • Low(er) power factor loads do not consume more energy, but they do draw more RMS current • A component in an electrical system (such as a lighting fixture on a circuit) with low power quality metrics does not necessarily degrade the power quality of the system, due to the potential for compensating effects among connected, interacting components in that system.

Managing risk • Concerns over the power quality of a new technology replacing an incumbent should be weighed in context with: – the power quality of the incumbent – the relative power or current draw vs. the incumbent – the power quality and relative power or current draw of other connected components in the system.
• Specify ANSI C82.77-2002 recommendations today • The next update to ANSI C82.77 (currently under development) will take into account the expected market adoption of LED sources • Be aware of power quality design trade-offs – Cost, components, potentially lifetime and reliability – Some LED driver architectures commonly used in low-cost replacement lamps have a fundamental power factor vs. flicker trade-off
• Contact DOE if: – You have any evidence of a power quality problem caused by the installation of LED sources – You are planning a large retrofit of LED sources with power quality performance that does not meet ANSI C82.77-2002 recommendations Michael Poplawski, Pacific NW NaNonal Lab (PNNL), Power Quality Myths and MisconcepNons: What you need to know, LightFair Intl, June 2014 11
Light Loss Factors: What Are They? • All lighting systems decline in lumen output over time due to reductions in lamp emissions and changing surface properties— lamp, luminaire, and room, if applicable. • This is accounted for by using a Light Loss Factor (LLF) during the design process. • A Light Loss Factor is a multiplier that is used to predict future performance (maintained illuminance) based on the initial properties of a lighting system. • LLF = 1 – Expected Depreciation • The Total LLF is determined by multiplying the independent effects of multiple factors.

CALiPER Report 20.1 Conclusions • In each category, at least one LED lamp was rated more favorably than the benchmark halogen. Halogen should not always be considered the ideal source for lighting quality. • Single-emitter LED lamps were favored in both beam quality and shadow quality • Poor color consistency within the beam, and stray light outside the main beam pattern, were the attributes most likely to be noted by the observers as negatives • LED lamps with narrow spot distributions were generally viewed as having less-acceptable beam quality than their narrow-flood or flood counterparts • Observers generally preferred 3000 K LED lamps over 2700 K LED lamps, but their ranking of color quality did not always correlate with the CRI of the lamps Full report available at: http://apps1.eere.energy.gov/buildings/publications/pdfs/ssl/caliper_20.1_par38.pdf Kelly Gordon, Pacific NW NaNonal Lab (PNNL), Spotlight on Par38s, LightFair Intl, June 2014

Some SSL products currently on the market have equal or be,er flicker performance than tradiNonal lighNng technology. Some SSL products currently on the market are clearly well outside the flicker frame of reference established by tradiNonal lighNng technology, and modulaNng luminous flux in previously unseen manners. Flicker index and percent flicker correlate fairly well at lower levels of percent flicker (< 40). However, shape variaNon captured by flicker index separates otherwise similar (same percent flicker) products at higher levels of percent flicker. SSL products currently on the market exhibit wide variaNon in flicker performance. Flicker performance is directly related to the LED power electronic driver, since luminous intensity is (approximately) proporNonal to current through the LEDs (Wilkins, 2010; IEEE PAR1789, 2010).

CRI
C
Short for color-rendering index, CRI is the ability of a light source to show the colours of objects accurately. The higher the CRI on a 1-100 scale, the more accurately the lamp will render colors. Lamps with poor color rendering will distort some colours. CRI only works for approximately white sources and doesn’t actually tell you which colours a light source renders well or badly.

An LED driver is a self-contained power supply that has outputs matched to the electrical characteristics of your LED or array of LEDs. There are currently no industry standards, so understanding the electrical characteristics of your LED or array is critical in selecting or designing a driver circuit. Drivers should be current-regulated (deliver a consistent current over a range of load voltages).

$1.2 billion savings over 5 years on energy, water & chemical costs. 670% ROI So the financial incentive is there, but as CEO Pasquale Pistorio stressed, it’s not enough. “If the chief executive is not totally committed, it won’t succeed,” Pasquale Pistorio, CEO, STMicro, 1987-2005
STMicro Carbon Positive & Revenue Positive SHRINK: Reduce total emissions of CO2 due to our energy consumption (tons of CO2 per production unit) by 5% per year: SHIFT: Adopt whenever possible renewable energy sources of wind, hydroelectric, geothermic, photovoltaic, and thermal solar. SOURCE: Compensate the remaining direct CO2 emissions through reforestation or other carbon sequestration methods, to reach CO2 direct emissions neutrality by 2015.
Between 1998-2010 STMicro planted 10 million trees in reforestation programs in Morocco, Australia, USA, France and Italy (9,000 ha total). 179,000 tons of CO2 sequestered.

as utility-scale PV in Chile. As solar technology gets cheaper we expect households and businesses to increasing opt for solar systems . There will however be opposition from utilities and changing rate structures for consumers. The first signs of this trend can already be observed : in Spain , for example , the government has threatened to impose a tax on electricity generated for
auto-consumption , although the final bill is still pending . Ultimately however we don't believe Global Residen6al-‐Scale Solar PV System Economics developments such as this will have a material effect on the size of the market in the long term ,

particularly as the small-scale power storage solutions become increasingly viable .
