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.

Hello,

I think you are looking for the AFN Linkage Node Volume Flow Rates. DesignBuilder will generate the necessary output variables and send them to the EnergyPlus engine.

Output:Variable, *, AFN Linkage Node 1 to Node 2 Volume Flow Rate, Hourly;
Output:Variable, *, AFN Linkage Node 2 to Node 1 Volume Flow Rate, Hourly;

Thank you! I think it is the solution but I have not the scripting module so I need to add these outputs on an .idf file and inlcude it in the simulation. I have another question: which is the meaning of Node 1 and Node 2? Thanks F

You don't need the Scripting module to generate AFN linakge flow rates. Simply request to "Store surface output" and "Store opening/sub-surface output" and if you are using Custom outputs also specify "Airflow In" and "Airflow out" results.
