Hi Joe,
I also believe that the fan size is probably determined by the maximum heating, not the cooling, load. However, I don't understand why after determining the airflow, it doesn't adjust the cooling coil to have a similar capacity as the building HVAC maximum cooling load (SS-D report).
Would you like to see the input/output files?

Thanks for your help
