摘要

This paper proposes a new extended power law (EPL) of air infiltration in buildings as an alternative in certain cases to the widely used power law (PL) and quadratic law (QL). Specifics: it separates the airflow rates in laminar and turbulent components; improves the estimation of the leakage area; new evaluation of the airflow rate at low pressure differences. In various numerical comparisons several advantages of EPL are revealed and we appreciate that will raise interest and adoption by the software platforms that evaluate the airflow in buildings.
