1. E NERGY S TAR ® E NERGY S TAR Refrigerators and Freezers Richard H. Karney, US DOE July 18, 2001

2. Review of Analysis Methodology

3. Why expand? Industry/Utility/Consumer interest New Models Available Provide motivation to increase product efficiency Provide more efficient option for common household purchase Expansion of Coverage and Eligibility

4. Current Refrigeration Spec Standard size refrigerators only >12.5 ft 3 for top-mount freezer >18 ft 3 for side-by-side, bottom Initial specification intended to include most common sizes

5. Proposed Addition to Specification Coverage Mid-sized refrigerators 6.5 to 18.5 ft 3, all configurations Freezers (manual & auto) All residential sizes Compact refrigerators/freezers < 6.5 ft 3 Manual & partial defrost All sizes

6. Proposed E NERGY S TAR Levels for Expansion 10% below NAECA standard No change Maintain consistency with current specification Consistency aids consumer understanding Exception Compact refrigerators/freezers 20% below NAECA proposed

7. Mid-size Refrigerators: Market Overview Estimated annual sales: 1.9 million Top mount freezer most common

8. NAECA and E NERGY S TAR: Mid-size

9. Proposed E NERGY S TAR Level: Mid-sized Refrigerators 10% below NAECA standard Consistent with current speciation

10. Compacts: Market Overview Annual Sales: 2.4 million Mostly Manual Defrost Sales Volume Doubled in Last Five Years

11. NAECA and E NERGY S TAR : Compacts

12. Proposed E NERGY S TAR Level: Compacts 20% below NAECA standard Why not 10%? 20% created better differentiation Greater energy savings

13. Freezers: Market Overview 2 million units/year sales 36 million unit stock 1 in 3 households Two manufacturers have 99% of market

14. NAECA and E NERGY S TAR: Upright Freezers

15. NAECA and E NERGY S TAR: Chest Freezers

16. Proposed E NERGY S TAR Levels: Freezers 10% below current NAECA standard Currently, freezers at 10% below NAECA do not exist Manufacturers stated they will produce more efficient product upon introduction of E NERGY S TAR expansion

17. Estimated Energy Savings Assume 10% market penetration in first year Freezers:13.6 GWh Compacts: 8.2 GWh Mid-sized: 8.7 GWh

18. Estimated Energy Savings Formula Model technique: Weighted average size (ft 3 ) times average unit energy consumption improvement times annual shipments of Energy Star Units Give aggregate annual consumption

19. Options to Improve Performance Improve insulation HCFC blown Ins. ends in 2004 New materials being considered Improve compressor performance ECMs for condenser/evaporator Onboard demand management

20. Conclusion These are proposed performance levels Please make comments today Reminder: Final comments due August 2
