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
