DCV: Load test and VAV control form!

DCV: Load test and VAV control form!

We recommend an automated load test with minimum and maximum supplied airflow rate to all the rooms for maximum and reduced AHU load conditions.

If it is not possible to perform an automated load test because of the chosen components and or programming, we recommend checking all the rooms by measuring the airflow rate for maximum and minimum fan speed, for maximum and reduced system load. This control test should be documented with a completed VAV control form.

In buildings with many rooms with similar function, a random sampling according to the EN 12599 standard can replace the complete load test.
