# .BuildSysPro.IBPSA.Airflow.Multizone.Examples.PressurizationData

Model showing how the 'Powerlaw_1DataPoint' model can be used when data is available from a pressurization test.

## Information

This model illustrates the use of IBPSA.Airflow.Multizone.Point_m_flow to model infiltration through the building evelope for a known n50 value (also known as ACH50). As the n50 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 IBPSA.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.
