color:#1F497D'>I believe you can use the Overall Design Flow (ASSIGNED-FLOW) at
the zone level to set your maximum flow rate. It’s in CFM not ACH
but you can let eQuest do the math for you. In the “Edit/View User
Expression” box enter: 12*#LR("SPACE","AREA")*10/60.
Where 12 is your ACH rate (use a Global Parameter to make life easier when you
start changing it in the parametric run) and 10 is your floor to ceiling height.

<p class=MsoNormal>This should be a quick question, but with eQuest you never
know.<br>
<br>
I am trying to set my ACH rates to 12, and in an parametric run, turn it down
to 6. This doesn't appear to be working because the entry line for the
ACH is minimum air to the zone. <br>
<br>
Is there a way to set the air flow to see the ACH minimum air as a maximum?<br
