     Purpose
• Update residential appliance measures to 6th Plan supply curves:
   • Dishwashers
   • Clothes washers
   • Refrigerators
   • Freezers
• June 29th RTF Meeting
   • Presentation of methodology for all appliances
   • Approval of:
      • full update to SF clothes washers
      • savings methodology for dishwashers.
• Today
   • Approval of updates for dishwashers (including cost), refrigerators,
     and freezers.
   • Revisit baseline assumption for clothes washers
                                                                                                     Slide 2

Methodology – as presented at the last RTF meeting
• Identify available measure datasets
• Define baseline as average performance of dataset
   • sales weighted where possible
• Establish appropriate measure tiers
• Identify algorithms for translating performance metrics into energy and
  water usage.
• Determine energy and water savings, relative to updated baseline
• Normalize savings to account for differences in features across
  baseline and measure groups (e.g. tub volume, refrigerator volume).
• Present proposed savings, compare to current PTR savings and
  identify causes for change.

     Energy and Water Algorithms

    • Primarily DOE, mostly as used in 6th Plan (FY10) Analyses




                                                                                                     Slide 4

    Datasets
• California Energy Commission Appliance Database
   • Manufacturer reported performance metrics and date of
      submission
   • QC: checked against CEE certification data where possible for
      accuracy
   • CEC datasets used in 6th Plan analysis, but more recent version of
      the database used for this analysis.
   • Cleaning: remove duplicates (same manufacture and specs,
      different model #); incomplete records; and records older than the
      date that the current federal standard went into effect.

• Oregon Tax Credit
   • 2007 data included in 6th Plan analysis, and used for this analysis
   • Sales volume, basic performance metrics, retail price
                                                                                                    Slide 5

    Datasets
• DOE Bottom-up Cost Estimates
   • Incremental cost of improved efficiency determined from a
     materials and manufacturing perspective.
   • Costs scaled up to account for pass-through of cost to retail level

• Association of Home Appliance Manufacturers (AHAM)
   • Shipment weighted average performance and specifications for
     dishwashers, clothes washers, refrigerators, freezers

• D&R International –
   • Energy Star market share. Estimates of efficiency for Energy Star
     and non-Energy Star appliances.

    SF Clothes Washers - Revisit
    • Savings and costs approved at June 29th RTF meeting
       • Approved MEF of 1.93 – average of models in CEC
         database from January 1, 2007 to the present.
       • Since then, additional 2009 AHAM data published
       • Additional baselines to consider:
           • AHAM 2009 data (available as of July 2010)
           • AHAM data extrapolated to 2010 to account for
             increasing efficiency over time.

    • Setting the baseline for clothes washers impacts measures
      savings, non-programmatic savings, and 6th plan achievable
      potential

    SF Clothes Washers – Baseline Options
    • Keep CEC DB baseline (1.93) –
       • Pro: accounts for trending
       • Con: not based on sales weighting
    • Use AHAM 2009 data (1.85) –
       • Pro: most recent shipment weighted data available
       • Cons:
          • one year out of date for an appliance that continues to
            improve
          • Energy Star criteria increases from 1.8 (current) to 2.0
            in January 2011, suggesting a bump up in market
            average.
    • Use AHAM data extrapolated to 2010 (1.91) -
       • Pro: Uses most recent shipment weighted data available
         with marginal increase
       • Con: MEF increase trend is not linear; extrapolation may
                                                                  Slide 9

•Also used to determine average performance within each group (e.g. “any

                                        Dishwashers
Today
•Current and upcoming federal, Energy Star, and CEE criteria
•Baseline options
•Cost model
•Usage: Adjusting for capacity
    •Does larger capacity imply less cycles per year?
•Additional inputs (lifetime, load shape, water costs and embodied
energy)
•Results
    •More efficient dishwashers tend to be larger and have more non-
    energy utility (special features, brand).
    •Results, including cost-effectiveness, are very sensitive
    baseline and usage assumptions

            As with clothes washers, three options
            • CEC DB baseline (EF = 0.71) –
               • Pro: accounts for trending
               • Con: not based on sales weighting
            • Use AHAM 2009 data (EF = 0.68) –

     Dishwashers – Incremental Cost Model
• Bottom-up incremental costs from DOE/Navigant Consulting
  background analysis in 2006 for appliance efficiency standards.
   • Material and other manufacturing costs to produce estimated
   • Cost scaled to retail level
• Results not finalized and published on EERE website because the
  federal standard it was intended to support was superseded by the
  Energy Independence and Security Act of 2007 (EISA).

                 Dishwashers – Usage Options
On average, more efficient washers are also larger
  (higher place settings rating).

Three usage options
1) Constant number of cycles per year
    • (215 cycles per year)
    • Independent of washer capacity
    • Interpretation: Users use washer at fixed times, regardless of
       how full the dishwasher is.
2) Constant number of place settings per year,
    • Assume CEC DB average place settings and 215 cycles per
       year. (215 cycles per year x 11.7 place settings)
    • Interpretation: Users use washer when it’s full
3) Average of 1) and 2)
    • Interpretation: Users sometimes use washer at fixed times,Slide 21

Res. Freezers – Baseline Development
Approach
• Use CEC data to determine average % more efficient than federal
  standard by group:
   • {Energy Star, non Energy Star} x {configurations}
• Use AHAM and Energy Star market share data to determine the
  weighting of each group
