                         INTRODUCTION
The Importance of Energy-Efficient Appliances
Using appliances and heating and cooling equipment costs an average
household more than $1000 per year. You can sharply reduce your own
energy bill by using high-efficiency appliances and space conditioning
equipment. Highly efficient appliances may be slightly more expensive to
buy than comparable models with lower or average efficiencies. However,
the extra first cost for a more efficient appliance is paid back through
reduced energy bills long before the product wears out.

Energy-efficient appliances also have a positive effect on the national
economy and the environment. The efficient use of oil, gas, and electricity
cuts petroleum imports, improves US. economic competitiveness, and
reduces the environmental degradation associated with energy production
and use.

One-third of the electricity produced in the U.S. is consumed in our homes.
Refrigerators alone use the equivalent of the output of over 20 large nuclear
power plants-about 5% of the nation’s total electricity consumption. If all
the households in the US. had the most efficient refrigerators currently
available, the electricity savings would eliminate the need for about 10 large
power plants!

National Appliance Efficiency Standards
On March 17, 1987, President Reagan signed into law the National
Appliance Energy Conservation Act of 1987. This law established minimum
efficiency standards for major home appliances and heating and cooling
equipment. The standards for clothes washers and dishwashers took effect
January 1, 1988, requiring a cold water rinse option on new models. The
standards for most other appliances took effect on January 1, 1990. The
standards for central air conditioners and furnaces will not take effect until
1992, because it will take longer to make the necessary changes in these
larger products.

We estimate that these standards will save consumers at least $28 billion
over the lifetimes of the products sold through the year 2000, or about $300
per household. Furthermore, the standards will reduce peak electricity
demand by the equivalent of 25 large power plants.

Even though the standards eliminate the production of energy-guzzling
appliances, consumers can still benefit from selecting highly-efficient
appliances that significantly exceed the national appliance efficiency
standards. These high efficiency appliances provide the opportunity to
achieve substantial energy savings. Appliances are still available over a
broad range of efficiencies, and consumers would be wise to shop carefully
                                                                             1
    for efficient models. After all, the air conditioner, furnace, or refrigerator you
    buy today will still be in use 15 or 20 years from now.

    Utility Rebate Programs
    Some utilities offer rebates to consumers who purchase energy-efficient
    appliances. Rebates reduce the net purchase price of high-efficiency
    models, making them even more attractive to consumers. By offering
    incentives for the purchase of high-efficiency equipment, utilities are buying
    energy “supplied” through conservation at a lower cost than through
    traditional means, such as building new power plants.

    Rebates are most common on high-efficiency heat pumps and central air
    conditioners. Rebates on room air conditioners and water heaters are also
    sometimes available. Rebate programs are more common among electric
    companies than gas companies, although some gas utilities offer rebates
    for high-efficiency furnaces and other products. If you plan to buy a major
    appliance soon, ask your utility if they offer rebates for efficient models.

    The Information in this Booklet
    This booklet lists, to the best of our knowledge, the most energy-efficient
    residential appliances available in the US. as of July, 1990. Because of
    space limitations, only the very highest-rated models are listed within each
    appliance category. The models listed here represent fewer than 5% of all
    the different models currently available. Many more appliances are above
    average in terms of efficiency, but space limitations prevent us from listing
    them all.

    Our lists are based on information in the most recent product directories
    published by the appliance industry associations. We have tried to include
    highly efficient models not listed in the directories where information is
    available. However, we only include models that are mass-produced and
    widely-distributed in the US. Also, we only include products for which there
    are standardized efficiency ratings. Therefore, this booklet does not cover
    ranges, ovens, clothes dryers, solar water heaters, wood stoves, tankless
    water heaters, portable space heaters, or air-to-air heat exchangers.

    The efficiency ratings are based on the standardized tests that manufactur-
    ers are required to conduct on their products. The same test ratings are
    used on the yellow EnergyGuide labels now required for most home
    appliances. The lists of refrigerators, freezers, clothes washers, and
    dishwashers include the estimated annual energy cost as it appears on the
    most recent EnergyGuide labels. The base price of energy (such as the
    cost per kilowatt-hour of electricity) used to determine the price on the
    EnergyGuide labels has changed in recent years. Some labels based on
    the older, cheaper cost can still be found in showrooms. Therefore, when
    comparing EnergyGuide labels, use the same energy price.

The lists of furnaces, boilers, water heaters, air conditioners and heat
pumps include their efficiency ratings instead of estimated energy use and
cost. The energy use for these appliances varies greatly from house to
house depending on climate, family size, and other factors. But the
efficiency rating is a good indicator of relative energy use and operating
cost-the higher the efficiency, the lower the energy use and operating cost.

We realize that energy performance is one of several important criteria for
selecting home appliances. We do not collect information on product
reliability and other concerns. However, energy-efficient appliances are
generally high quality products due to the better materials and components
used in their construction.

The model numbers in this booklet are used by manufacturers in their
product directories. In some cases, appliance dealers use abbreviated
model numbers (for example, dropping the first number or letter). An asterisk
(*) appearing in a model number indicates a digit or letter that varies with
features of the appliance not affecting efficiency and capacity (for example,
color).

How to Use This Information
When you buy an appliance, you pay more than just the sales price-you
commit yourself to paying the cost of running the appliance for as long as
you own it. These energy costs can add up. For example, running a
refrigerator for 15-20 years typically costs three times as much as the initial
price of the refrigerator.

The sum of the purchase price and the energy costs of running an
appliance over its lifetime is called its lifecycle cost. The lifecycle costs of
energy-efficientappliances are typically lower than the lifecycle costs of
average models. Worksheets for comparing the lifecycle costs of different
models of appliances are provided on page 27 of this guide.

When shopping for major appliances, you may want to call several stores
or dealers to check the price and availability of different models. Ask the
salesperson for information about the efficiency of each model. The yellow
EnergyGuide labels can help you compare similar models. We recommend
that you disregard the ranges listed on the EnergyGuide labels, since they
have not been updated for some time. In comparison shopping, use only the
information given for the particular models you are considering.

If you cannot find some of the models listed in this guide, you can still use
the information in this booklet to your advantage. Compare the efficiencies
of the models you can find to those listed here. The models listed in this
booklet represent a very small fraction of all the new appliances now
available; you may find products that just missed getting listed in this edition.

                                                                               3
                              REFRlGERATORS
    The energy efficiency of refrigerators has improved considerably over the
    past fifteen years. A typical new refrigerator with automatic defrost and a
    top-mounted freezer uses about 1000 kWh per year, whereas the typical
    model sold in 1973 used about 2000 kWh per year.

    The 1990 National Appliance Efficiency Standards specify the maximum
    electricity consumption allowed by refrigerators, according to volume and
    features. On average, the 1990 standards result in a 343% improvement in
    average efficiency over 1989 and earlier models. An even greater jump in
    efficiency will occur in 1993 when the next phase of the standards take
    effect.

    The models listed below are grouped by door style, defrosting capability
    and volume. Models are listed within each group in order of increasing
    electricity use. If two different sized refrigerators use the same amount of
    electricity per year, the larger model would be considered more efficient
    because it keeps more space cold with the same amount of electricity.

    The energy costs shown below are based on an electricity price of 8 cents
    per kWh. Your actual energy cost may differ depending on the price of
    electricity in your area and how you use the refrigerator.

    The energy efficiency of freezers has improved over the past decade,
    though at a slower rate than refrigerators. Like refrigerators, the national
    standards for freezers took effect in 1990.

   DISHWASHERS AND CLOTHES WASHERS
Most of the cost of running dishwashers and clothes washers is for heating
water. Therefore, an efficient water heater helps reduce the costs asso-
ciated with these appliances. The annual energy costs shown below are
based on a typical electric water heater and an electricity price of 7.7 cents/
kWh (the prices used on the most recent yellow EnergyGuide labels).

The energy efficiency of a water heater is indicated by its Energy Factor
(EF), an overall efficiency based on the use of 64 gallons of hot water per
day. The national appliance efficiency standards for water heaters took
effect in 1990. The standards are based on storage tank size, as indicated
below:

                          Minimum Energy Factors (EF)
Tank Size                      Gas                       Oil                Electric
30 gallons                     0.56                     0.53                 0.91
40 gallons                     0.54                     0.53                 0.90
50 gallons                     0.53                     0.50                 0.88
60 gallons                     0.51                     0.48                 0.87

All other things being equal, the smaller the water heater tank, the higher
the EF. Compared to small tanks, large tanks have a larger surface area,
which increases heat loss from the tanks and decreases the energy
efficiency.

Of course, the capacity of the water heater is an important consideration.
The water heater should provide enough hot water at the busiest time of the
day. For example, a household of two adults may never use more than 30
gallons of hot water in an hour, but a family of six may use as much as 60
gallons in an hour. The ability of a water heater to meet peak demands for
hot water is indicated by its “first hour rating” (listed in the “rating” column
below). This rating accounts for the effects of tank size and the speed by
which cold water is heated. The models listed below are grouped by their
tank size.

              HEAT PUMP WATER HEATERS
A heat pump water heater operates on the same principal as a refrigerator
or an air conditioner-it removes heat from the surrounding air and delivers
it to the water in the tank. Heat pump water heaters use about 1/3 as much
electricity as ordinary electric resistance water heaters.

                   ROOM AIR CONDITIONERS
Room air conditioners are rated by their Energy Efficiency Ratio (EER), the
ratio of the cooling output divided by the power consumption. The higher the
EER, the more efficient the air conditioner.

The 1990 national standards for room air conditioners vary with the design
and cooling capacity of each unit. On average, the 1990 standard requires
a minimum EER of about 8.6.

             CENTRAL AIR CONDITIONERS
Central air conditioners (CACs) are rated according to their Seasonal
Energy Efficiency Ratio (SEER). This is the cooling output divided by the
power input for an average U.S. climate. The average new CAC sold in
1988 had a SEER of about 9. The national appliance efficiency standard for
split system central air conditioners will take effect in 1992, requiring a
minimum SEER of 10.

Many older CACs have SEERSof only 6 or 7. If you need or want to replace
the outdoor (compressor) unit of your current air conditioner, make sure the
indoor (blower coil) unit is compatible with the new outdoor unit. A highly
efficient outdoor unit may not achieve its rated efficiency if paired with an
older blower coil. Ask your serviceman to properly match your system to
achieve its highest efficiency.

The air conditioners listed below are grouped by their cooling capacity;
each “ton” represents 12,000 BTU/hour of cooling capacity.

                      CENTRAL HEAT PUMPS
    Central heat pumps provide both cooling in the summer and heating in the
    winter. However, heat pumps do not perform well over extended periods of
    sub-freezing temperatures. The cooling performance of heat pumps, like
    that of central air conditioners, is rated as a SEER. Heating performance is
    measured by the Heating Season Performance Factor (HSPF), a ratio of the
    estimated seasonal heating output divided by the seasonal power con-
    sumption for an average US. climate. A typical new heat pump has an
    HSPF of about 6.5 and a SEER of about 9. The national appliance efficiency
    standard for split system heat pumps will require a minimum HSPF of 6.8
    and a minimum SEER of 10, effective in 1992.

    The heat pumps listed below are grouped by their heating and cooling
    capacities and ranked in order of their heating efficiencies. If you live in a
    region with significant heating and cooling seasons (e.g., mid-Atlantic
    states), you should seek a heat pump that performs well in both seasons.
    If you live in a region where summer cooling is much more important than
    winter heating (e.g., Florida), then you will want a unit that is particularly
    efficient for cooling.

                          GAS FURNACES
New furnaces are rated by their Annual Fuel Utilization Efficiency (AFUE),
a measure of overall seasonal performance. The average new gas furnace
sold in 1988 had an AFUE of 75%. The national efficiency standard for
furnaces will take effect in 1992, and it will require that each furnace have
an AFUE of at least 78%. Furnaces are available over a broad range of
efficiencies, depending on the sophistication of the equipment:

Furnace feature                                              Typical AFUE
Gas pilot light (no efficiency features)                          62%
Electronic ignition                                               68%
Automatic vent damper                                             76%
Power combustion                                                  82%
Condensing furnace                                                go(+)%

Condensing furnaces are often priced much higher than less efficient
furnaces. Accordingly, condensing furnaces are most economical in areas
with long, cold winters. Homeowners in regions with moderate or mild
winters may find that furnaces with AFUEs in the 80% to 85% range are
their best buys. Also, when buying a new furnace, make sure the capacity
is appropriate for your home (an “oversized” furnace will operate less
efficiently).

                         OIL FURNACES
The national standard for oil furnaces is the same as that for gas furnaces:
a minimum AFUE of 78% in 1992. High efficiency oil furnaces achieve their
high ratings through automatic flue dampers and “flame retention” burners.

      COMPARISON SHOPPING AND LIFECYCLE
                   COSTS
    The best appliance buy is not necessarily the least expensive model nor the
    one with the highest efficiency. Computing and comparing lifecycle costs
    of different models can identify the best buys. A lifecycle cost of an
    appliance is the combination of its purchase price and the annual operating
    costs over its useful lifetime. This section explains lifecycle costs and
    provides worksheets for your use.

    To compute a lifecycle cost, you will need to know:

    1. The purchase cost (the price you pay the appliance store or contractor).
    2. The cost of energy (from your utility bill or your local utility).
    3. The yearly energy cost to operate the appliance (obtained from the
       EnergyGuide label using your local cost of energy).
    4. The estimated lifetime of the appliance in years, given in Table 1.
    5. A discount factor, a number that adjusts for inflation and for the fact that
       a dollar spent today does not have the same value as a dollar spent in
       the future, since today’s dollar could be invested and earn interest over
       time. Discount factors are given in Table 1.

    The following formula is used to calculate lifecycle costs:

                                                                        DISCOUNT
                                                                           RATE     )
    Consider the following example: You want to do a lifecycle cost comparison
    between Refrigerator A and Refrigerator B. You call your local utility and
    learn that electricity costs 10 &/kWh. You look at the EnergyGuide labels on
    Refrigerators A and B. The Yearly Cost table toward the bottom of the
    EnergyGuide label shows that at an electricity price of 10 cents per kWh,
    Refrigerator A has an annual energy cost of $100 while Refrigerator B has
    an annual energy cost of $120. The price on model A is $600, and the price
    of model B is $520. You check Table 1 on this page to find the correct
    lifetime (20 years) and discount factor (0.76) for refrigerators. With this
    information, you can now compare the lifecycle costs of the two
    refrigerators:
                                         Annual
                         Purchase        Energy   Estimated   Discount   Lifecyle
    Appliances             Price          cost     Lifetime    Factor     cost
    Refrigerator A        $600      +   ( $100  X     20    X   0.76 ) = $2120
    Refrigerator B        $520      +   ( $120  X     20    X   0.76 ) = $2344

    From this calculation you learn that the refrigerator with the more expensive
    purchase price, model A,will actually cost you $224 less than the cheaper
    model over its lifetime.

Unfortunately, accurate lifecycle cost comparisons between different central
air conditioners and furnaces must also include information concerning
local climate and the condition of a home. Therefore, this procedure for
computing lifecycle costs does not apply to these products.
