Below are the list of outputs that I generally use to calculate the Load through ventilation, infiltration, exfiltration, mixing and others when I invoke AFN objects. Few of the HVAC based outputs give zero values when the zones are assigned with Natural ventilation.
I remember using volume flow rate output and heat transfer formula (Q=c×m×ΔT) in EP EMS to derive heat transfer into and from zone just from fenestrations.
