Airflow measurements at supply air terminal devices on residential balanced ventilation systems

In France, the control of ventilation system at commissioning is mandatory in the context of the Effinergie + label and the measurement of airflows in residential houses is mandatory since 2017 in this label. The Promevent project (2013-2016) was aiming at improving the reliability of those controls. Guidelines have been issued for visual inspection of system, airflow measurements at air terminal devices (ATD) and ductwork airtightness measurements.
