[EnergyPlus_Support] Cooling loads decrease when ventilation and/or Infiltration increases

Hi all,

I am simulating to see differences in the Cooling loads for different Infiltration and/or Ventilation.
Cooling loads decrease when ventilation and/or Infiltration increases, but normally energy demand by air conditioning will increase when opening windows at the same time.
I think is decreasing because is only considering that Tout is smaller than Tin and not considering differences in humidity.

I am checking "HVAC Input Sensible Air Cooling [GJ]" in file called "idfnameTable.xls" and also variable "Zone/Sys Sensible Cooling Energy". 

Do you know how can I do a realistic simulation of cooling loads versus Ventilation?

Thank you very much,

Jose
