  1. Commercial Refrigeratorsand Freezers Efficiency Standards, Savings, and Cost RTF Meeting September 30, 2008 (continued from July 1, 2008 meeting, with more Cost discussion)

  2. Background • Model Variations • Door Type • Sold Door • Glass Door • Combination • Temperature • Refrigerator • Freezer • Combination • Aesthetics • Standard Line • Specification Line • Purpose • Reach-In • Under counter • Roll-in/Roll-through • Pass-through • 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

  3. Efficiency Standards • CEE: • OR & WA • Minimum efficiency standards in place earlier this year (CEE Tier 1). • Federal Minimum • Will go into effect 2010 (CEE Tier 1) • Energy Star • Currently set at the same level as CEE Tier 1, OR and WA code and the 2010 Fed minimum (exception: No standard for glass-door refrigerators or freezers). • New spec to be finalized by April 2009, to go into effect January 2010.

  4. Energy Savings • CEE Tier 1 Energy Use – CEE Tier 2 Energy Use • Updated analysis using new CEE lists. • Savings weighted equally based on CEE list • kWh/year:

  5. Cost • Previous version of RTF assumptions used a 3 year payback as the basis for the incremental cost. Available Data • ADL Report – Re-design for Efficiency at Manufacturer Level • PG&E Workpaper - Catalog/online price research • Available Online data

  6. Cost Data #1Re-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

  7. Cost Data #2PG&E Workpaper (Catalog price research) Solid Door Refrigerators Glass Door Refrigerators Solid Door Freezers • Note: “Cost” is 60% of manufacturer list price. “Average Cost” and “Minimum Cost” are normalized by volume.

  8. Cost Data #3Available 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.

  9. Cost Discussion • How best to determine incremental cost? • Difference of averages? • How to weight? • Difference of minimums? • Is it $0.00?

  10. Recommendations • Update Savings based on most recent CEE list. • Combine Glass Door and Solid Door Refrigerators as one measure by using the average savings: • Assume Incremental Cost is $0. • Efficiency standards remain at CEE Tier 2 levels until Energy Star specifications are put in place.
