1 Analysis of Cost and Savings Values for Revised Energy Star Freezers and Refrigerators June 6, 2006 Revised August 8, 2006

Original Refrigerator Results – Corrected for “weighting” Error Measure Name Incremental Capital Cost (2000$/unit) Annual Site (kWh/yr) Benefit / Cost Ratio Energy Star Refrigerator with Bottom Freezer - No Ice $ Energy Star Refrigerator with Bottom Freezer - Ice $ Energy Star Refrigerator with Top Freezer - Ice $ Energy Star Refrigerator with Top Freezer - No Ice $ Energy Star Refrigerator - Any Configuration $ Energy Star Refrigerator with Side-by-Side - No Ice $ Energy Star Refrigerator with Side-by-Side - Ice $

3 Proposed Resolution of Outstanding Issues Side-by-Side Refrigerators are represent a growing share of the market and the market share data used to derive “any refrigerator” values is 10-years old. –Use 2005 Shipment Weights from AHAM Incremental cost data derived from both Tax Credit and online retailers appear to indicate that Energy Star cost for this configuration are 9-10 times higher than other configurations. –Use Manufacturer Cost Data from DOE TSD

Corrected Original Refrigerator Cost Assumptions Compared To DOE Measure Name RTF Cost Estimates DOE Cost – Manufacturer Estimates DOE Cost – Regression Estimates Energy Star Refrigerator with Bottom Freezer - No Ice $12$31$43 Energy Star Refrigerator with Bottom Freezer - Ice $18$31$43 Energy Star Refrigerator with Top Freezer - Ice $27$31$43 Energy Star Refrigerator with Top Freezer - No Ice $27$31$43 Energy Star Refrigerator - Any Configuration $68 $31$47 Energy Star Refrigerator with Side-by-Side - No Ice $199$31$59 Energy Star Refrigerator with Side-by-Side - Ice $217$31$59
