1. Commercial Refrigerators and Freezers
Efficiency Standards, Savings, and Cost
RTF Meeting
January 5th, 2010
(continued from July 1, 2008 meeting, with more Cost discussion )

2. Background Model Variations Where savings come from Door Type
Sold Door
Glass Door
Combination
Temperature
Refrigerator
Freezer
Configuration
Standard
Chest
Aesthetics
Standard Line
Specification Line
Where savings come from
Improved face frame design
Lower wattage anti-sweat heaters
High efficiency evaporator and condenser fan motors
Higher efficiency compressor
Optimized refrigeration system design
Improved insulation
Improved glass doors

3. Old & New Efficiency Standards
Federal Minimum set at CEE Tier 1 (old Energy Star Standard) Effective Jan 2010 (OR & WA min. standard was already in effect)
New Energy Star 2.0 Standard
Effective Jan 2010 for all equipment (early start April 2009 for some equipment types)

4. Energy Savings Analysis
Savings = Average “Market” Energy Use – Average Energy Star Energy Use
Energy Use Based on
Oct 2009 CEE List of Equipment, filtered for unique models
Solid and Glass Door Refrigerators
Solid Door Freezers
List Used in EPA analysis of Energy Star Standard (NR Canada and Mfgrs)
Glass Door Freezers
Chest Freezers and Refrigerators
Assumes each unique model on the list gets equal weighting in the “market”

10. Including these in the average skews the savings
No units > 20 cu.ft. meet Energy Star

11. Off the Chart to 6,091 kWh/year

12. Cost
Previous version of RTF assumptions used a 3 year payback as the basis for the incremental cost.

13. Cost Data Source #1 Re-design for Efficiency at Manufacturer Level
In 2002, ADL/DOE/Delfield re-designed the Delfield “Vantage” refrigerator line.
$0 incremental cost (actually less expensive to produce than the baseline model)
68% energy savings over baseline model

14. Cost Data Source #2 PG&E Workpaper (Catalog price research)
Solid Door Refrigerators
Solid Door Freezers
Glass Door Refrigerators
Note: “Cost” is 60% of manufacturer list price. “Average Cost” and “Minimum Cost” are normalized by volume. “Energy Star” = EStar V.1

15. Cost Data Source #3 Online Price data
Notes
Data from Manufacturer’s Published List Prices
2003 Traulsen Price List
2008 Beverage Air Catalog
“Cost” is 60% of manufacturer list price. “Avg Cost” is size (cu.ft.) normalized average.

16. Cost Data Source #4
| Solid Door Refr | Glass Door Refr | Solid Door Freezer | Glass Door Freezer |

17. Cost Data Source #5 Cost = 50% of list price.
Incremental cost = difference in cost between a baseline unit and a unit meeting the Energy Star 2.0 spec.
CEE data adjusted to assume entire market for baseline cost.

18. Cost Summary & Conclusion
Summary: Cost varies dramatically through various data sources.
Difficult to compare equipment with like feature sets.
Proposal: Use average cost by refrigerator/freezer and door type categories.

19. Recommendation Decision???
Efficiency standard becomes Energy Star 2.0 (no longer CEE Tier II).
Update Savings based on new Energy Star Standards, using available equipment lists to categorize the market.
Use average incremental cost from all sources.
Measure Life = 12 years.
Decision???
