[Equest-users] Airflow Schedule based on Occupancy

[Darryl Kasun via Equest-users]

Hi everyone,

I have a zone that is served by a VAV system.  The controls for the zone
state that when the zone is occupied, the VAV box should be fully opened
and when unoccupied, the zone supply air be reduced to 6 ACH.  There are
multiple zones controlled in this manner.

To model this I am thinking of creating a min airflow schedule that matches
occupancy schedule.  The minimum hourly fraction within the min airflow
schedule would be equivalent to the airflow fraction of 6 ACH.

In other words, if there are hourly fractions in the min airflow schedule
(which is a copy of the occupancy schedule) that are below the equivalent
fraction of 6 ACH, those hours would be changed to the 6 ACH fraction.

Hopefully that makes sense to you.

This method seems fine to me but a bit tedious as it will require
developing multiple min airflow schedules.

Any thoughts?
