[Equest-users] Specifying ERVs and outdoor air flow

[Chris Jones]

I have a question about the correct way to specify an ERV and the 
outdoor air flow in a system.

In my example, the roof top unit serves a single zone.  The AHU has 
an ERV that recovers heat from 1200 cfm of outdoor air.  This flow is 
specified in the System, Outside Air and Economizer, Heat Recovery 1.

Should the outdoor air flow also be specified in the single zone 
served by this AHU?  If I don't specify where the outdoor air goes, 
the SV-A report for that zone shows no outdoor air.  From that, it 
would seem to me that I should specify the outdoor air flow in the zone.

Thanks for any help with this issue!
