This model illustrates the use of
Buildings.Airflow.Multizone.Point_m_flow
to model
infiltration through the building evelope for a known n_{50} value (also known as ACH50).
As the n_{50} value and the building volume is known,
the flow at 50 Pa is known. Dividing this flow accross the entire envelope
(typically surface weighted) and using
Buildings.Airflow.Multizone.Point_m_flow,
the infiltration airflow at lower pressure differences can be modelled.
In this example, the two models each represent 50% of the surface where airflow occured due to the pressurization test.
