7 Computer Model Ship GuidelinePower 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 SupplyWatts (W) in Sleep Mode 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 300W 350W 400W < 15W < 20W < 25W < 30W < 10% of power supply's maximum continuous output rating < 30W < 15% of power supply's maximum continuous output rating < 200W > 200W Key Product Criteria for E NERGY S TAR Labeled Monitors (effective July 1, 1999) Low-Power ModeFirst Low-Power "Sleep Mode" Second Low-Power "Deep Sleep" Mode Maximum Watts in Low-Power State < 15 Watts< 8 Watts 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 !

8 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

9 Biggest household power consumer 1990 Refrigerators 900 kwh /yr Energy Star Refrigerators 10% less than NAECA 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 + 3559.8*AV + 276 Side Mount Freezer w/o through-the-door ice 11.8*AV + 5014.91*AV + 507.5 Bottom Mount Freezer w/o through- the-door ice 16.5*AV + 3674.6*AV + 459 Top Mount Freezer with through-the-door ice 17.6*AV + 39110.2*AV + 356 Side Mount Freezer with through-the-door ice 16.3*AV + 52710.1*AV + 406 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

10 Side By Side 24.5 – 26.4 cu. Ft

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

12 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.

14 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.

16 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

17 Regular Light Bulb Wattage ENERGY STAR Wattage Electricity Savings (over 6,000 hours, at 8.5 cents per kwH) 40 watts15 watts$13 60 watts20 watts$20 75 watts25 watts$25 100 watts32 watts$34 Note: CFL USE 75% Less Energy CFLs cost between $5 -$15 CFL - 6000 hours, incandescent – 1000 hours CFL = Energy Star

18 Exposure can effect: 1. Brain 2. Spinal Cord 3. Kidneys 4. Liver Exposure Causes: 1. Memory Loss 2. Difficulty Moving 3. Trembling Hands

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

20 1. No levels! 2. Higher Models = More Money 3. Standards are not up to technological advances 4. For Some Appliances Too Close to Minimum Federal Standard 5. CFL Special Disposal 6. 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.

21 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!
