PRELIMINARY ANALYSIS 

ENGINEERING ANALYSIS DETAILS FOR DIRECTLY ANALYZED 

EQUIPMENT CLASSES

The following tables illustrate the design option analyses used to calculate the 

incremental manufacturer selling prices at varying efficiency levels. The tables show analyses 

for equipment classes that were directly analyzed for this rulemaking. 

Further detail is available in Chapter 5 of the ACIM Preliminary Analysis Technical 

Support Document (TSD):

pdf. However, note that tables 5.10.2 and 5.10.4 of the preliminary TSD, labeled “Incremental 

Manufacturer Selling Price” actually show incremental manufacturing production cost.
