  1. Deemed Savings Analysis for Residential Energy Star Refrigerators May 7, 2002

  2. Goal of the Analysis • Determine whether there is a reasonable “point estimate” for the cost and savings of Energy Star Refrigerators in Residential Applications • Pre-Implementation of the July 2001 Federal Standard • Post-Implementation of the July 2001 Federal Standard

  3. Reason for Analysis • C&R Discount Program participants must now use “deemed calculation” to claim credit for Energy Star Residential Refrigerators • Two versions of the “deemed calculation” are available • OLD Values (available until October 1, 2002 • NEW Value (updated to reflect change in Federal Standards & Energy Star Program post July 2001

  4. Approach • Collect Energy Use Data on ALLCurrently available Energy Star Models • Estimate Savings by Product Configuration (side-by-side, top freezer, with & without ice maker) • Over pre-July 2001 Federal Standard • Over post-July 2001 Federal Standard

  5. Incremental Cost Analysis - Approach • Collect Current Retail Prices for Energy Star and Non-Energy Star Residential Refrigerators • Source – Sears.com • 100 Side-by-Side (48 Energy Star) • 118 Top Freezer (31 Energy Star) • 33 Bottom Freezer (16 Energy Star) (“White” models only)

  6. Incremental Cost Analysis – “Some” Results

  7. Relationship Between Refrigerator Retail Price and Volume is Strongly Correlated

  8. Relationship Between Refrigerator Volume and Annual Energy Use is Moderately Correlated

  9. Relationship Between Refrigerator Retail Price and Annual Energy Use is Poorly Correlated

  10. Incremental Cost Analysis – “Some Other” Results

  11. So Why the Difference in Estimated Incremental Costs? • Non-Energy Efficiency features of Energy Star models (Estar’s have more “through the door ice”) • Differences in “Brand” mix between Energy Star and Non-Energy Star model (Estar’s have more “premium” brands) • Difference in Average Volume of Energy Star and Non-Energy Star Models (Estar’s are larger)

  12. Examples • Side-by-Side w/Ice Maker • Kenmore Brand Only - $270 price difference • All Brands - $312 price difference • Top Mounted Freezer (18 cu.ft.) • GE Brand Only - $59 • All Brands - $69

  13. Results - Savings Pre-Space Conditioning Interaction Adjustment

  14. Results - Savings Post-Space Conditioning Interaction Adjustment

  15. Regional Bulk Power System Benefit/Cost Ratio

  16. Results – Rate Discount Credit Post-Space Conditioning Interaction Adjustment
