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
