Greetings to everybody.

I am modelling a free flowing residential house through an airflow network for i intend to use some passive strategies for induced ventilation in the house for my thesis.

From what i gathered infiltration in the Airflow network is modeled either through surface cracks or surface effective leakage area.

Is there any literature on the difference between the 2 ? Is there a set of lookup values (tables ) for concrete walls ?

How about the reference crack conditions ? what are the values that should be used. I have no access to the house for physical measurements.

Thank you for your help
