Refrigerator Stats

• Biggest household power consumer
• 1990 Refrigerators ? 900 kwh /yr
• Energy Star Refrigerators 10 less than NAECA

• No standard Size
• Use AV (Adjusted Volume)
• AV (Fresh cu ft.) 1.63(Freezer cu ft.)

• Energy Star Claims
• Better Insulation
• More Efficient Compressor
• Improve Heat Transfer Surfaces
• More Precise Temperature and Defrost Mechanisms
• Keeps Kitchen Cool

Refrigerator Analysis

• Energy Star Refrigerators ? Save 5.00 /yr
• Initial Investment 100
• Payback time 20 yrs.

NOTE The reason why Energy Star
Refrigerators are not economically sound is
because you have to buy higher model
numbers in order to receive an energy star on the
refrigerator. The higher price paid is
caused by both the extra features in the
higher models as well as modifications made to
meet energy star standards.

Dishwashers

• Loads 322 ? 264 /yr.
• Most have standard size
• EF (loads per year) / (annual energy usage)

• This Model Save 13 /yr by
• No pre-rinsing
• Effective Wash Action
• Energy Efficient Motor
• Sensors determine cycle length temp.

Note Energy Star Dishwashers suffer from
the same economical issues as refrigerators. The
higher cost is due to features as well
as energy star. Therefore, extra features most
likely have to be bought in order to buy an
energy star model.

Washing Machines

• Based on 392 loads /yr
• No standard size tub volume
• Compared based on Energy Factor (392Volume cu
  ft.) / (Annual energy usage kwh)
• New! MEF Modified Energy Factor includes
  dryer work

This model saves 45 /yr by 1. Superior design
less water / larger basket 2. Sensors regulate
water usage and water temp 3. Water Extraction

Heating and Cooling

• Boiler Criteria
• AFUE Annual Fuel Utilization Efficiency of
  85
• accounts for fuel use, electricity use, and fans
  used in the furnace
• 6 more efficient than national standard

• Room Air conditioner criteria
• EER Energy Efficiency Ratio BTU rating /
  wattage
• 10 above new NAECA
• 15 above old NAECA

• Programmable Thermostat Criteria

Criticisms

• No levels!
• Higher Models More Money
• Standards are not up to technological advances
• For Some Appliances Too Close to Minimum Federal
  Standard
• CFL Special Disposal
• Energy Star Only Examines One Attribute (Energy
  Efficiency) of
• Products Life Cycle
• What About
• 1. Raw material extraction,
• 2. Manufacture
• 3. Transportation
• 4. Use of the product
• 5. Recycling
• 6. Disposal.

Conclusions

• DO NOT Blindly follow the star
• READ the ENERGY GUIDE
• Buy Appliances that fit your needs! Bigger does
  not mean better!
• Do a side by side comparison of the products
• Target the cheapest changes to yield higher
  efficiency
• Such as
• Washing Machines
• Computers
• REMEMBER Energy Star only targets product
  efficiency!
