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
