[Equest-users] Zone report OA discrepancy

[Min-Hwan Yang]

Brett,

It looks like your critical zone caused that.  It seems you have reduced cooling CFM by trying to reduce cooling load at exterior zones. 
By reducing cooling CFM the program bumped OSA ratio to meet the zone OA requirement.  I would suggest you should increase the min. CFM of box serving the critical zone (G.SSW4).

Thanks,

When looking at my Zone Air-Side Summary Report I noticed that the proposed system OSA cfm was about double that of my baseline building. However, all the zone OSA quantities are equal. Does anyone know what could cause this discrepancy? I have attached pdf files for both the proposed and baseline report. Thanks in advance.
