Green is good!

Americans are concerned about the environment

• 82% of Americans say they believe in global warming and there is widespread belief that human behavior is contributing to the problem. (Fox News/Opinion Dynamics Poll, Spring 2007)

• 93% strongly agree that “saving energy helps the environment” (EPA Study by Interbrand)

• 86% would choose one home over another based on its energy efficiency. (Shelton Group/Energy Pulse 2006)

ENERGY STAR is…

• …a voluntary government-backed program sponsored by the Environmental Protection Agency (EPA) and the Department of Energy (DOE) that helps businesses and individuals protect the environment through superior energy efficiency

• …designed to identify and promote energy-efficient products to reduce greenhouse gas emissions

• …the national symbol of energy efficiency

• Introduced by the EPA in 1992

• Computers and monitors were the first labeled products

• The label is now on over 50 product categories from over 1700 manufacturer partners

• Public awareness of ENERGY STAR is over 70% and 80% would recommend ENERGY STAR products

• In 2007 Americans saved $16 billion on their energy bills with ENERGY STAR products. This prevented greenhouse gas emissions equivalent to the emissions of 27 million cars

What makes it ENERGY STAR?

ENERGY STAR qualified products:

• meet strict independent testing

• adhere to stringent specifications that address efficiency and quality

• require certain information on products and appropriate logo use as a condition of partnership

• are randomly tested twice a year to ensure ongoing quality

• are labeled to be easily identifiable to consumers

• are cost effective

Benefits of ENERGY STAR Qualified Lighting

Less Heat = reduces cooling costs

Less Energy = lower utility bills

Excellent color rendering ( ≥80 CRI) = colors look natural

Electronic Ballast = flicker-free, no hum or buzz.

2-year warranty = customer security

Instant-on = customer satisfaction

How do CFLs work?

• Electricity passes through a phosphor coated tube filled with gas containing argon and mercury

• The electricity excites the gas, causing it to emit ultraviolet light

• When the light passes through the phosphor on the tubes, it is turned into visible light

• Fluorescent lighting requires mercury to operate. This includes linears, CFLs and enclosed lamps. CFLs of today have much less mercury than linears of the past.

Why choose ENERGY STAR qualified fixtures over CFLs?

• Fixtures are designed for the lamp source– They are more likely to have the correct sized lamp– The appropriate type of glass is used– Better distribution of light

• Permanent savings for the homeowner– Dedicated base for pin-based lamps

• Longer lamp life– ENERGY STAR fixtures are rated at 10,000 hours for a fixture vs.

CFLs at 6,000 hours (many do last longer)

Wattage Conversion(the 4 to 1 rule)

First Cost vs. Second Cost

• ENERGY STAR qualified lighting may be more expensive up front, but over the lifetime of the light it will more than pay for itself, saving time and money.

• A 3-lamp fixture pays for itself in less than 2 years!

Simple cost based on energy savings only and does not include cost of lamp(s).

CFLs last up to 10 times longer than incandescent lamps and use 75A% less energy (www.energystar.gov)

Lifetime is 10,000 hours of lamp life for CFL and 1000 hours for an incandescent, which may need to be replaced up to 10 times over the lifetime rating of a CFL. ENERGY STAR qualified CFLs have a minimum rated life of 8,000 hours, whereas the CFLs in ENERGY STAR qualified fixtures are rated for 10,000 hours.

Electric rate used in this calculation is $ 0.08

Choosing the Right Application

• Where to use ENERGY STAR qualified lighting– Where lights are on 3+ hours a day– In hard to reach fixtures and locations– In select enclosed outdoor light fixtures – Where brighter light is needed in a fixture without exceeding its

maximum rated wattage– Where a higher color temperature light is desired

• Dimming Solutions– Use GU24 base fixtures for most applications but choose an

incandescent fixture from the same family for the dining room. NUVO makes it easy by providing incandescent families to match the energy efficient choices.

– Ensure you use a DIMMABLE CFL in a dimming application other wise you risk a fire

Choosing the right CFL

• Use the 4-to-1 rule in CFL lighting. – Replace a 60 watt incandescent

with a 13 or 15 watt CFL

• Match the “color” to a typical incandescent (2700 Kelvin)– Choose a brighter Kelvin

temperature for brighter, cooler color.

• CFLs come in many shapes and sizes including globes, A-lamps, bullets and torpedoes

Color Temperature

• Color Temperature is measure in Kelvin (K) with standard incandescent lighting at 2700K

• A lower Kelvin, such as 2700K or 3000K means the color of the light is warmer, so it brings out yellows and reds

• A higher Kelvin, such as 5000K or 6500K produces a cooler, bluer light that brings out blues

• CRI = The ability of a lamp to reproduce color as accurately as incandescent light or natural daylight.

• The CRI scale ranges from 0 to 100.

• ** All ENERGY STAR qualified lamps intended for indoor use are 80 CRI or higher

Mercury

• ENERGY STAR qualified CFLs have a maximum mercury content requirement:

• Lamps less than 25 watts < 5mg per lamp• Lamps 25 to 40 watts < 6mg per lamp• Satco CFLs have far less than this requirement, about

1.6 mg up to 26W. Enclosed lamps contain even less.

• The amount of mercury in a CFL is the size of the tip of a ballpoint pen, or a period in a book.

• The EPA’s CFL fact sheet estimates 3.6 mg of mercury is avoided during a five-year period of bulb use.

Mercury Disposal

• Dispose of mercury in accordance with local laws• Recycling is the best option - www.lamprecycle.org• If that is not available, double-bag your CFL and take it to

your local waste site or place in the trash

• If a CFL breaks…• open a window and leave the room for 15 minutes (to remove any

mercury vapor). • carefully sweep up the broken pieces and powder with a piece of

cardboard or stiff paper (to remove any liquid mercury). Place in a plastic bag. Do NOT vacuum.

• wipe are with a damp cloth and throw away in same plastic bag.

The Energy Independence and Security Act (EISA) of 2007

• Does not “ban the bulb.” It simply sets new, more demanding efficiency standards on lighting (among other things)

• Section 321 sets efficiency standards for “general service” light bulbs that will essentially phase-out the most common incandescent light bulbs by 2012-2014. The initial standards can be met by advanced incandescent (including halogen) bulbs, which are being introduced to the market; compact fluorescent lamps (CFLs); and light-emitting diodes (LEDs).

• Specialty bulbs, including chandelier and appliance bulbs, are exempted from the standards

• Reflector lamps are the first lamps affected
