1. A method comprising:
receiving airflow setpoint values from each of a plurality of variable air volume (VAV) units to determine a combined airflow set point for the plurality of VAV units of an air handling unit (AHU);
determining an effective static pressure setpoint for the AHU based on a relation between the combined airflow setpoint value and a static pressure represented by a system effect curve;
operating the AHU at the effective static pressure setpoint;
monitoring, by the AHU, a damper position of each VAV unit for determining a starving VAV unit from the plurality of VAV units and computing the effective static pressure setpoint of the AHU based on a relation between the combined airflow setpoint value and a static pressure represented by a system effect curve;
determining, by the AHU, an offset for the starving VAV unit; and
adjusting, by the AHU, the offset to the effective static pressure setpoint of the AHU for the starving VAV unit.
