APPENDIX B: DETAILED REVERSE ENGINEERING COST ESTIMATES AND

EQUIPMENT DATA

The following tables present the detailed cost estimates from the reverse engineering analysis

for each product class aggregated by efficiency level. Values in Bold typeface have been substituted

from other product classes in accordance with the rules presented in Section 4.2.7. Values in normal

typeface result directly from the reverse engineering methodology detailed in Appendix C.

The charts and graphs following the tables provide information on the distribution of the

design options included in the reverse engineering samples at each efficiency level. It is important

to keep in mind that the reverse engineering sample represents only a small portion of product

currently on the market. Since manufacturers identified the samples as being the closest available

representation of their baseline product under new efficiency levels, they do not necessarily represent

the most prevalent equipment sold and used today. Furthermore, products under new standards

would likely evolve to be more uniform in design than those illustrated.
