I am using openstudio to model doas system which are ducted with vrf. I first tried to run packaged rooftop hp measure to each zone and create a separate vrf loop. but after auto sizing everything, the ventilation rate for this packaged rooftop unit is 2 times higher than I calculated in ventilation spreadsheet for doas system per IMC. I checked ventilation template per zone and plenum. looks like nothing run with the input Thank you
