.IDEAS.Airflow.Multizone.Examples.PressurizationData

Information

This model illustrates the use of IDEAS.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 IDEAS.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.
