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

Figure 3: ESPC Basic Structure

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.

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.

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

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.

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 ,
