  1. Energy Star • Background – History • Criteria – What Gets a Star? • Evaluations – Economical View • Criticisms • Key Points • Packets Goal: Promote and Identify Energy Efficient Products that reduce greenhouse gas emission

  2. Energy Star for Business Green Lights merger Refrigerator AC Dishwashers Energy Star Timeline EPA Introduces Green Lights Program Energy Star printers Energy Efficient Homes 30% Mortgages available For energy star homes March 1995 October 1996 January 1991 January 1993 October 1995 December 1996 1991 92 93 94 95 96 97 December 1997 April 1995 June 1992 October 1994 June 1996 March 1997 EPA &DOE Boilers Exit signs Clothes Washers Energy Star Copiers, transformers Central air, Programmable thermostat 1st Energy Star labeled Products Computers and Monitors Energy Star Fax Light Fixtures Scanners

  4. Key Product Criteria for ENERGY STAR Key Product Criteria for ENERGY STAR Product Product TV Phase I Standby Mode VCR TV/VCR Combination Units Phase II Standby Mode Consumer Audio Products Standby Mode < 3 Watts < 2.0 Watts < 4 Watts < 6 Watts < 1.0 Watt DVD Products < 3.0 Watts < 1.0 Watt Energy Star Criteria Electrical Vampires Electronics of the Night • TV 5.9 non-star • VCR 5.1 non-star • Audio 3.2 watts non-star • DVD 4.5 watts non-star • Phase I ends 12/31/02 • Phase II begins 01/01/03

  5. Vampire Analysis Note: Household estimate of 101,041,000 is based on 1998 estimations from U.S. Census Bureau Estimations based on $0.1 /kwh Key Points: - payout $8.59 /yr less when using Energy Star per household - Save $75.69 over the lifetime of the product per household - Save United States 7.6 billion dollars over the lifetime of the product * Energy Star Electronics Usually carry no extra incurred costs over non-energy star systems

  6. Computer Model Ship Key Product Criteria for ENERGY STAR Labeled Monitors(effective July 1, 1999) Guideline Power Consumption Before July 1, 2000 • Shall enter a sleep mode within 30 minutes of inactivity • If shipped with network capability, shall sleep on networks and respond to wake events Power Supply Watts (W) in Sleep Mode Low-Power Mode First Low-Power "Sleep Mode" Second Low-Power "Deep Sleep" Mode Maximum Watts in Low-Power State < 15 Watts < 8 Watts On & After July 1, 2000 • Shall enter a sleep mode within 30 minutes of inactivity • If shipped with network capability, shall sleep on networks and respond to wake events Guideline A:< 200W> 200W < 300W> 300W < 350W> 350W < 400W> 400W < 15W< 20W< 25W< 30W< 10% of power supply's maximum continuous output rating Computers & Monitors < 30W < 15% of power supply's maximum continuous output rating < 200W > 200W If left in sleep state 24 hours a day for a year = 263 kwh /yr = $21.76 If left on 24 hours a day for a year = 1752 kwh/yr = $145.07 Save $123.31 !

  7. Appliances Electric Hoarders Energy Star Backs: 1. Refrigerators – 10% under NAECA 2. Dishwashers – 25% better the NAECA EF 3. Washing Machines – 50% better EF of 2.5 / MEF of 1.26 Not Backed: 1. Dryers 2. Ovens 3. Ranges 4. Water Heaters

  8. Current NAECA maximum energy use(kWh/year) Current NAECA maximum energy use(kWh/year) effective July 1, 2001 Top Mount Freezer w/o through-the-door ice 16.0*AV + 355 9.8*AV + 276 Side Mount Freezer w/o through-the-door ice 11.8*AV + 501 4.91*AV + 507.5 Bottom Mount Freezer w/o through-the-door ice 16.5*AV + 367 4.6*AV + 459 Top Mount Freezer with through-the-door ice 17.6*AV + 391 10.2*AV + 356 Side Mount Freezer with through-the-door ice 16.3*AV + 527 10.1*AV + 406 Home Appliances Refrigerator Stats • No standard Size • Use AV (Adjusted Volume) • AV = (Fresh cu ft.) + 1.63*(Freezer cu ft.) • Biggest household power consumer • 1990 Refrigerators  900 kwh /yr • Energy Star Refrigerators 10% less than NAECA • Energy Star Claims: • Better Insulation • More Efficient Compressor • Improve Heat Transfer Surfaces • More Precise Temperature and Defrost Mechanisms • Keeps Kitchen Cool

  9. Side By Side 24.5 – 26.4 cu. Ft

  10. Top Mount Freezer 22.5 cu. Ft – 24.4 cu. ft

  11. 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.

  12. 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.

  13. Washing Machines • Based on 392 loads /yr • No standard size tub volume • Compared based on Energy Factor = (392*Volume 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 Technology

  14. Regular Light Bulb Wattage ENERGY STAR Wattage Electricity Savings (over 6,000 hours, at 8.5 cents per kwH) 40 watts 15 watts $13 60 watts 20 watts $20 75 watts 25 watts $25 100 watts 32 watts $34 Change a light, Change the world CFLs - Compact Fluorescent Bulbs Note: CFL USE 75% Less Energy CFLs cost between $5 -$15 CFL - 6000 hours, incandescent – 1000 hours CFL = Energy Star

  15. CFLs? Don't They Contain Mercury? Exposure Causes: 1. Memory Loss 2. Difficulty Moving 3. Trembling Hands Exposure can effect: 1. Brain 2. Spinal Cord 3. Kidneys 4 . Liver

  16. 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 ThermostatCriteria: • 1. 2 programs (weekday/weekend) • 2. 4 temp. / program • Saving are 20 – 30% *Note: To Be an Energy Star Home Must Use 30% less Energy For Heating, Cooling, and Water Heating

  17. 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.

  18. 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!
