Subject: [Equest-users] Supply / Return Fans - Reporting kW values<BR>
<BR>
Dear all,<BR>
<BR>
<BR>
<BR>
I am modeling an elementary school for LEED purposes, and currently<BR>
appealing for the EA Prerequisite 2.<BR>
<BR>
<BR>
<BR>
In the baseline model:<BR>
<BR>
<BR>
<BR>
My zones are supplied by several AHUs, each delivering an amount of air<BR>
that includes both re-circulated and fresh air. When determining the<BR>
baseline fan power, I am using the attached excel sheet. The supply air<BR>
(column C) includes the fresh air (column E) plus return air (Column F).<BR>
This sheet gives me the total supply kW/CFM in (Column N). The question<BR>
is:<BR>
<BR>
<BR>
<BR>
In eQUEST, given that my supply kW/CFM includes the return air, do I<BR>
need to zero out any return fans kW when inputting the AHU parameters?<BR>
My thought is that I must put them as zero, because I would be double<BR>
counting the return air consumption if I didn't.<BR>
<BR>
<BR>
<BR>
Best regards,<BR>
<BR>
Omar<BR>
