Residential Clothes Washer Measure Overview
• Baseline Type: Current Practice
• Current Category: Proven

• Reason for Update/Review: New sales data provided by Bonneville suggests a significantly different
Current Practice baseline efficiency than our current CEC* proxy
*California Energy Commission appliance database

Current Practice Baseline• RTF’s current practice baseline intends to represent
“recent choices of eligible end users in purchasing new equipment and services”1
• Sales data is ideal for this purpose but difficult to come by
• Our typical solutions:– Shipment data as proxy (even this is hard to come by)
– Product registry (or availability) as proxy• RTF currently uses the CEC’s appliance database as the most
reliable resource for product registry

Summary of Updates
• Re-weighted energy savings and incremental costs to reflect the new ENERGY STAR® saturation estimate
• One limitation to note:– CEC data still used to estimate the efficiency
distribution of machines within the D&R survey bins• E.g. the D&R sales data does not tell us how many
machines are barely Energy Star vs. far beyond Energy Star– However, proposed weighting scheme is significantly
improved over current scheme

Summary of Changes to Savings, Cost, TRC
• Energy Savings – Increased by 43 to 136% (note: some savings values were relatively
small before)• Incremental costs
– Increased by 33 to 114%• Life
– No change• TRC Cost-Effectiveness
– All measures remain cost-effective• A comparison of current to proposed savings, cost, and TRC
can be found on the Presentation tab of the proposed workbook
