like I am getting somewhere. I started fresh with the building input

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The project is an elementary school and we are using ground
source HP to produce chilled water and hot water. One system to serve the
chilled beams and one system to serve the air handlers, DOAS and FCUs. The
reason behind this split is, chilled beam requires high chilled water temp.
Anyway, I am attaching the hp schematic and the waterside loop summary-which is
close to the design values. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am using the IU for the chilled beam and I am getting the
O/A from the dummy zone that I set up. Right now, I am not liking output
summary of the DOAS.- please see attached. On the initial run that I had
equest run the simulation using the O/A from the induction unit, the
cooling capacity is way too high but the O/A CFM and design CFM is what the
area calls for. The second has less capacity but ventilation is good but
the Design flow CFM is too much. The tonnage of the unit is still higher
that the design, looks like the ERV savings were not accounted for. The
lesser capacity tonnage was derived from the manually inputed Maximum cooling
rate of the unit on the dummy zone level. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

Is there a guideline on howto setup the dummy zone for DOAS system?<o:p></o:p></span></font></p>
