For glazing, you have to enter the GLASS-CONDUCTANCE into eQuest, not the glazing U-value. See page 65 in the DOE22Vol2-Dictionary reference manual available for download at doe2.com.

Dear all, I have a problem reporting baseline case for LEED submission, where the exterior walls and windows U-values in Report LV-D appears less than the ASHRAE G 90.1 values that I did enter to the model, and this is (as I think) because eQuest adds the exterior air-film effect to the assembly during the run.
My question is that; can I disable this eQuest calculation to see my input directly in LV-D report or not?
Thanks,

The LV-D reports (and others touching on windows/constructions) do indeed
include an exterior air film. I don?t know of a way to change that.

A quick screengrab of your (correct) inputs and a one-line explanation of
that fact is probably your most expedient path forward for a LEED review
response.
