Commercial Refrigeratorsand Freezers

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

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

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).

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

8
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
• PGE Workpaper - Catalog/online price research
• Available Online data

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

Cost Data 2PGE 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.

Cost Data 3Available Online Price data

• Notes
• Data from Manufacturers 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.

12
Cost Discussion

• How best to determine incremental cost?
• Difference of averages?
• How to weight?
• Difference of minimums?
• Is it 0.00?

13
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.
