Hello I am trying to calculate the air flow through the warehouse doors which I have in my project. The general idea is to inert the whole building. Therefore I calculatet the losses through the walls by the n50 value (0.01) (and the according correction term since I won't have any pressure inside to outside of the storage area except temperature).

The problem I have are the doors. I have a volume of about 200000 m3. The building will have 14 doors with 0.95m*0.95m. My question is how to calculate the air flow exhange rate through the doors. If I ask the supplier he does not tell me the way he is calculating ist (it is his know how). He tells me that he get's an average rate of 1300 m3/h. Can anybody tell me how to calculate this number?

Thank you for your help!

@LaTuor are you asking how to calculate the amount of infiltration airflow that specifically passes through doors separately from the walls and other parts of the exterior envelope of the warehouse?

Hello Boranian Yes, separately from the walls. I am interested in the doors amount only.
