Dear all,

I am modeling an elementary school for LEED purposes, and currently
appealing for the EA Prerequisite 2.

In the baseline model:

My zones are supplied by several AHUs, each delivering an amount of air
that includes both re-circulated and fresh air. When determining the
baseline fan power, I am using the attached excel sheet. The supply air
(column C) includes the fresh air (column E) plus return air (Column F).
This sheet gives me the total supply kW/CFM in (Column N). The question
is:

In eQUEST, given that my supply kW/CFM includes the return air, do I
need to zero out any return fans kW when inputting the AHU parameters?
My thought is that I must put them as zero, because I would be double
counting the return air consumption if I didn't.

Best regards,

Omar
