  • Energy STAR Program

2
ENERGY STAR
  • ENERGY STAR is a voluntary partnership between
  • U.S. Department of Energy
  • U.S. Environmental Protection Agency
  • Product manufacturers
  • Local utilities
  • Retailers

3
Energy STAR
  • Manufacturing Partners
  • Participate in development of targets
  • Participate in development of tests
  • Do the product design development
  • Place the Energy STAR logo on their products
  • Retailing Partners
  • Promote efficient products with the ENERGY STAR
    logo
  • Educate consumers about the unique benefits of
    energy efficiency product

4
Energy STAR
  • EPA promotes energy efficiency because
    electricity generation contributes to air
    pollution, including significant emissions of
    sulfur dioxide, nitrogen dioxide, and carbon
    dioxide, which are major contributors to the
    problem of global climate change

Washers
  • Front-loading ENERGY STAR models are similar in
    design to washers used in laundromats.
  • These horizontal-axis or tumble-action machines
    repeatedly lift and drop clothes, instead of
    moving clothes around a central axis.

8
Washers
  • Top-loading ENERGY STAR washers use sensor
    technology to closely control the incoming water
    temperature.
  • To reduce water consumption
  • spray clothes with repeated high-pressure rinses
    to remove soap residues rather than soaking them
    in a full tub of rinse water.

9
Washers
  • What does this mean to you? It means..
  • Nearly 50 percent less water and 30-40 less
    energy used per load
  • Washer design causes less wear and tear on
    clothes
  • Bulky items such as blankets fit easily in the
    super capacity basket.
  • Better water extraction means less dryer time,
    for further energy savings

10
Washers
  • A typical household does nearly 400 loads of
    laundry per year, using about 40 gallons of water
    per full load with a conventional washer.
  • In contrast, a full-size ENERGY STAR clothes
    washer uses 20-25 gallons per load. You could
    save as much as 7,000 gallons of water per year
  • And, you are saving all the energy that would
    have been needed to heat that water

Refrigerator
  • Your Home's Biggest Power User
  • The refrigerator is the single biggest power
    consumer in most households
  • A typical refrigerator made around 1990 uses
    about over 900 kilowatt hours per year - that's
    the same amount of energy you would use by
    leaving a 1,250 watt hairdryer on for a month!
  • The older your refrigerator is, the more power it
    burns

13
Refrigerator
  • ENERGY STAR refrigerators incorporate a number
    of advanced features to save energy
  • Better insulation - compressor needs to run less
    often to keep it cold
  • More efficient compressors
  • Improved heat transfer surfaces
  • More precise temperature and defrost mechanisms

14
Refrigerator
  • Also, improved insulation means that the
    compressor needs to run less often.
  • This keeps the kitchen cooler, since the
    compressor produces heat while it is running,
    actually reducing the need to air condition and
    improving comfort.
  • ENERGY STAR refrigerators must exceed minimum
    federal standards for energy consumption by at
    least 20.

15
Refrigerator
  • What about manual defrost refrigerators?
  • Manual defrost refrigerators are not covered
    under the ENERGY STAR program, but are generally
    more efficient than automatic defrost
    refrigerators.
  • Proper maintenance of manual defrost
    refrigerators is necessary to realize the energy
    savings.
  • The Department of Energy offers tips on buying
    refrigerators and lowering the energy usage of
    your refrigerator.

16
Save Energy While Keeping Cool
  • ENERGY STAR Room Air Conditioners feature
  • high-efficiency compressors
  • high-efficiency fan motors
  • high-efficiency heat transfer surfaces

17
ENERGY STAR Room Air Conditioners
  • Air is cooled when it passes over the refrigerant
    coils which have fins, similar to an automobile
    radiator.
  • Compressor sends cooled refrigerant through the
    coils, and cools the air as it is forced over the
    coils.
  • Using advanced heat transfer technologies, more
    of the heat from the air is transferred into the
    coils than in conventional models, saving energy
    required to compress the refrigerant.

18
ENERGY STAR Room Air Conditioners
  • ENERGY STAR Room Air Conditioners must exceed
    minimum federal standards for energy consumption
    by at least 15.
  • Buy The Right Size
  • Many people buy an air conditioner that is too
    large for the space, thinking it will cool
    better.
  • In an oversized air conditioner will actually be
    less effective than one that is the correct size,
    and waste energy at the same time.

19
ENERGY STAR Room Air Conditioners
  • Air conditioners remove heat and humidity from
    the air.
  • Humidity is removed when the air in a room passes
    over the cooling coils of an air conditioner.
  • If the unit is too large, it will cool the room
    quickly, but only remove a portion of the
    humidity. This leaves the room with a damp,
    clammy feeling to the air, since the air will not
    have been circulated enough.
  • A properly sized unit will remove humidity
    effectively as it cools.

20
ENERGY STAR Room Air Conditioners
  • AREA TO BE COOLED2 CAPACITY (BTU/HR)
  • 100 to 150 5,000
  • 150 to 250 6,000
  • 250 to 300 7,000
  • 300 to 350 8,000
  • 350 to 400 9,000
  • 400 to 450 10,000
  • If the room is heavily shaded, reduce capacity by
    10
  • If the room is very sunny, increase capacity by
    10
  • If more than 2 people regularly occupy the room,
    add 600 Btu/Hr for each additional person
  • If the unit is for a kitchen, increase the
    capacity by 4,000 Btu/Hr.

21
Electronic Appliances
  • TVs and VCRs
  • ENERGY STAR-labeled TVs require 3 watts or less
    of power when switched off, an energy savings of
    up to 75 over conventional models, which consume
    as much as 12 watts while off.
  • ENERGY STAR-labeled VCRs require 4 watts or less
    of power when switched off, an energy savings of
    up to 70 over conventional models, which consume
    as much as 13 watts while switched off.

22
Electronic Appliances
23
Electronic Appliances
  • ENERGY STAR labeled Home Audio products consume
    no more than 2 Watts when switched off. Home
    audio products include cassette decks, CD
    players/changers, clock radios ...
  • ENERGY STAR labeled DVD (digital versatile disk)
    players can consume only 3 Watts when switched
    off
  • Starting in 2003, ENERGY STAR Home Audio and DVD
    products will consume no more than 1 Watt when
    switched off.

24
Electronic Appliances
25
Office Equipment
  • Energy use by office equipment is one of the
    fastest-growing sources of electricity
    consumption in businesses and homes
  • It currently accounts for more than 7 percent of
    total commercial sector electricity use
  • Much of this energy is wasted because office
    equipment sits idle for long periods.

26
Fast Facts on Office Equipment
  • "If over the next 15 years everyone were to buy
    only those energy-efficient products marked in
    stores with EPA's distinctive ENERGY STAR label,
    we could shrink our energy bills by a total of
    about 100 billion over the next 15 years and
    dramatically cut greenhouse gas emissions."
    President Clinton during a speech to announce his
    climate change policy (Washington, DC), October
    22, 1997

27
Fast Facts on Office Equipment
  • In 1999, if everyone were to purchase only office
    equipment with the ENERGY STAR label, our nation
    would save about 1.5 billion a year in energy
    bills and cut the air pollution equal to the
    amount produced by more than 3 million cars.
  • Most computer users don't realize that while a
    screen saver is running, their monitor is not
    saving energy.
  • For a typical American business with 100
    computers, 10 laser printers and 3 copiers, more
    than 4,700 is spent each year to power the
    equipment. However, if the equipment is ENERGY
    STAR-compliant, only 2,081 is spent on this
    electricity.

28
Fast Facts on Office Equipment
  • An ENERGY STAR-labeled monitor consumes up to 90
    percent less energy than models without power
    management features.
  • Each year, consumers pay 1.8 billion in energy
    costs just to operate office equipment used in
    homes and businesses.
  • The average home office energy bill in the United
    States is 135. However, by purchasing an ENERGY
    STAR-compliant computer, monitor and fax machine,
    the average home office can cut its energy bill
    by as much as 45 percent.

EXIT Signs
  • As a nation, we spend about 1 billion annually
    to operate all the exit signs in buildings
  • By the year 2000, companies could be saving 800
    million kilowatts of electricity per year through
    the use of ENERGY STAR-labeled exit signs. That's
    a total savings of almost 70 million each year!
  • An ENERGY STAR-labeled exit sign operates on less
    than 5 watts per face, using less energy than a
    typical exit sign.

32
EXIT Signs
  • Each year, just one ENERGY STAR-labeled exit sign
    can save about 15-20 in electricity costs when
    compared with the typical, incandescent signs.
  • Most conventional exit signs are fitted with
    typical high-wattage incandescent bulbs, which
    use more electricity than newer technologies, and
    need to be replaced every few months.
  • One exit sign can cost over 30 each year to
    operate. Plus, additional maintenance costs to
    replace burnt-out bulbs can reach hundreds of
    dollars annually.

33
Retail Partner
  • More than 1,100 national and local retailers are
    advertising and labeling qualified products
    nationally, and many more retailers are joining
    the program..
  • Retail Partners receive
  • Free point-of-purchase and sales training
    materials
  • Listing on ENERGY STAR website store locator and
    federal consumer information hotlines
  • Access to utility and manufacturer promotions
  • Leverage from ongoing national brand awareness
    campaign

34
Retail Partner
  • In return, Partners agree to
  • Label qualifying products as they reach the
    showroom
  • Display point-of-purchase materials and consumer
    brochures in stores
  • Offer promotions on ENERGY STAR-labeled products
  • Advertise ENERGY STAR-labeled products in sales
    fliers
  • Conduct training for sales associates, using our
    special sales guide.

35
New Products
  • Given the success of these partnerships, EPA is
    expanding its ENERGY STAR Labeling Programs to
    include
  • Set-top Boxes
  • Commercial Ice Machines
  • Residential Spot Ventilation Fans
  • Ceiling Fans
  • Vending Machines
  • LED Traffic Lights
  • Telephony
  • Water Coolers
  • Residential Dehumidifiers
  • Reach-in Refrigerators and Freezers

36
ENERGY STAR Set-top Box Program
  • The new ENERGY STAR Set-top Box Program will
    include
  • Analog/digital cable boxes
  • HDTV and DTV converter boxes
  • Internet access devices (IADs)
  • Video game consoles
  • Direct Broadcast Satellite (DBS) systems
  • Videophone set-top boxes
  • Digital TV receivers

37
Set-top Box Program
  • WHY SET-TOP BOXES?
  • Substantial Standby Power Consumption. In standby
    mode (i.e., when switched off), set-top boxes
    continue to consume energy, in order to provide
    clock functions, remote control use, memory
    maintenance, and other features.
  • Market Penetration. According to Cahners In-Stat
    Group ("Set-top Market Frenzy," Electronic News,
    February 8, 1999) the market for set-top boxes
    (including only DBS, cable, and DTV boxes) is
    forecasted to expand to 7.4 billion by the year
    2002 from 3.9 billion last year.

38
Fast Facts
  • The amount of energy used when off is nearly
    equal to the amount needed to operate set-top
    boxes in their primary function or active mode.
    (LBNL, ACEEE)
  • Cable, satellite, and Internet access set-top
    boxes, as well as video game consoles, consume an
    estimated 7 billion kWh per year, producing
    pollution roughly equivalent to that of over 1
    million cars.
  • Americans spend over 618 million on utility
    bills to power these electronic devices. Set-top
    boxes consume much of this energy while consumers
    are not watching television or using these
    products.
