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 Analys is Technical

Support Document (TSD) :
