Rob,
 
You need to set up an hourly report. See attached.

How can i tell if the system is using a lower OA CFM during the less
occupied times?

Rob,
 
I recently modeled DCV successfully for the first time. (I showed
savings anyway.) You need to enter zone-level OA as OA-FLOW/PER and/or
OA-FLOW/AREA. The OA flow/per (person) is what will get you the savings,
based on your occupancy schedule(s). I also created a MIN-AIR-SCH,
coinciding with the fan schedule, set to zero when fan is off and -999
when fan is on.

I am having some trouble with setting up DCV in my model.  if i select
DCV in Zone Sensors for the Min OA Control Method and a min outside Air
Ratio, do i need any Zone level OA inputs?
Any help or insight as to what inputs are necessary for DCV would be
great!
