[EnergyPlus_Support] Re: Constant ventilation input results in varying ACH

["Jean marais" <jeannieboef@xxxxxxxxx>]

ACH is not equal to minODA. Your AHU is autosized to
a) meet the space loads whilst also introducing the minODA
b) make sure the minODA is delivered

Looking at it another way, the AHU is a recirculating air cooler/heater with a small ODA damper to inject just the minimum Outdoor Air that is additionally needed as ODA is in essance an additional load to be minimized at all times. 

I suggest you use the "AllSummary" report object.
