8.2. MEASUREMENTS
If some measurements are planned on the project, it is recommended to measure for acceptance of work:
·the airflow rates in each main room (supply) and each utility room (exhaust),
·the airflow when supply and exhaust ductworks are stopped up (spilages measurement),
(<40 m
3
/h with PWM fanmotors = 80% in the synoptic advanced tool)
·possibly, the sound level in the main rooms and very close to the fans,
