Engineering Analysis Validation Form - 04 October 2011

This form serves as a source of feedback for DOE's Engineering The information shared should allow DOE and 

manufacturers to verify which design configurations can achieve the draft efficiency levels.

The "Design Details" tab gives the design specifications for each design line. Please enter data in only 

the blue cells. The "Design Options" column has dropdown menus limiting combinations of design 

features to those DOE selected for modeling. Not every buildable combination is represented. For each 

efficiency within a design line, please enter the design details of your lowest first-cost design that can 

meet that efficiency, ideally, optimizing with respect to the same material costs that DOE uses. If you 

do not produce designs meeting those specifications (e.g., optimized with respect to different prices), 

please describe your modifications in the "Notes" column.

Additional information is requested that can be described as a summary Bill of Materials. With this 

BOM a first order price estimate can be prepared using the same material cost estimates (ex. $/lb) as 

used by DOE. This will provide an apples-to-apples comparison that avoids grouping design cost drivers 

from differences in material costs. The potentially large impact of material costs differences can be 

analyzed separately.
