Residential Appliance Measure Updates

Danielle GiddingBonneville Power Administration

Ryan Firestone and Wayne LeonardNavigant Consulting

August 3, 2010


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


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


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


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.


Single Family Residential Clothes Washers – Revisit of Baseline


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 not be appropriate


SF Clothes Washers – Baseline Comparison

• Note that shipment weighted average does not increase linearly

Residential Dishwashers


DishwashersJune 29 RTF

•Approved savings methodology

•Unique records from CEC DB used to estimate baseline (average of all records)

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


DishwashersToday

•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

Dishwashers – Baseline OptionsAs 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) –

• Pro: most recent shipment weighted data available

• Con: one year behind for an appliance that continues to improve

• Use AHAM data extrapolated to 2010 (EF = 0.70) -

• Pro: Uses most recent shipment weighted data available with marginal increase

• Con: EF increase trend is not linear; extrapolation may not be appropriate

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 OptionsOn average, more efficient washers are also larger

(higher place settings rating).

Three usage options1) 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, and sometimes use washer when it’s full

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
