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

Review of Analysis Methodology

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

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

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

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

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

NAECA and E NERGY S TAR: Mid-size

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

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

NAECA and E NERGY S TAR : Compacts

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

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

NAECA and E NERGY S TAR: Upright Freezers

NAECA and E NERGY S TAR: Chest Freezers

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

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

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

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

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