Residential Refrigerator UES Measure Update

1. Residential RefrigeratorUES Measure Update Regional Technical Forum April 16, 2013

2. Residential Refrigerator Measure Overview • Current Category: Proven • Current Status: Under Review • Current Sunset Date: April, 2013 • Reason for Update/Review: Sunset Date approaching; previous update recommended this workbook be updated every two years to capture changing baseline. • Baseline Type: Current Practice

3. Residential Refrigerator Measure Overview • Presentation shifts to Measure Workbook, “Summary Tab” • See Section “Measure Properties” and “Measure Identifiers”

4. MeasureWorkbook Update Summary • An updated extract from the California Energy Commission (CEC) database used to represent current market conditions. • Latest ProCost template used for this measure workbook; workbook formatted, sourced, and made easily updatable. • Measure EUL updated using DOE’s Technical Support Document (20 years to 17 years) • Source for previous workbook: FY10 Analysis Assumption • Source for proposed EUL: Latest DOE Technical Support Document • The proposed EUL value is consistent with the RUL value currently being used for Refrigerator Recycling.

5. MeasureWorkbook Update Summary • The previous RTF workbook used an average volume (21 Cu. Ft.) for all refrigerator configurations. • The proposed methodology uses an average volume for each configuration type as represented in the CEC database. (Explained further using the Workbook) • This proposed methodology is consistent with methodology for Commercial Refrigerators. • See graphic on “Presentation” Tab in the measure workbook. • Apart from updates to EUL and average refrigerator volume, the UES calculation methodology remain unchanged.

6. Remaining Issues for RTF Discussion • None.

7. PresentationShifts to Measure Workbook • “Summary” tab, sections “Constant Parameters” and “Energy Savings Estimation Method, Parameters and Data Sources” • “Presentation” tab

8. Summaryof Changes • Baseline conditions have become more efficient since the last update. • Previous Workbook showed Baseline to be 9% more efficient than Federal Standard Consumption. • Proposed baseline is 18 % more efficient than Federal Standard Consumption. • Due to the increase in baseline efficiency, energy savings have decreased for almost all Configuration Types and Efficiency Level combinations. • Incremental costs have decreased as well, but to a lesser extent than the Energy Savings decrease. • The following Category Type and Efficiency Level combinations do not pass TRC: • Side by Side with Ice Through Door – CEE Tier 3 • Side by Side without Ice Through Door – CEE Tier 2 and Tier 3 • Any Refrigerator, CEE Tier 1

9. Staff Proposal • Approve the updates to the residential refrigerator UES measure; • Set the measure status to “Active”; and • Change the sunset date to April, 2015.

10. Decision “I _______ move to approve the updates to the residential refrigerator UES measure; set the measure status to “Active”; and change the sunset date to April, 2015.”
