4. 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 registryappliance database 4 1 Complete Operative RTF Guidelines.

5. New Data 5 BPA provided sales data for clothes washers and other appliances Data collected by D&R International The table below represents sales for 2013 ENERGY STAR® saturation according to sales data: 54% ENERGY STAR® saturation according to CEC database: 78%

6. 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 6

7. 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 proposed workbook 7
