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
