Hello,

I have tried to see the windows flow rate with the calculated natural ventilation in DesignBuilder. I've inclued an .idf file in the simulation with:

Output:Variable, *, Zone Ventilation Air Change Rate;

but in the results there is not any number connected to the natural ventilation from the windows. How can I see the flow rate of the natural ventilation from the windows?

Thanks in advance, best regards, F.
