unmet cooling hours for 5 zones in MURB

i am facing a persistent unmet hours issue in energyplus 8.9. i have 5 zones, lobby and corridor spacetypes. served by the same Make up air unit with a cooling coil. there are separate DSOA objects defining OA as per space type. i have attempted varying the zone cooling sizing factor with no result. code requires those zones be set on NECB G thermostat schedule, ie: set to 22 degrees C during occupied hours. i have also attempted changing the heating & cooling sizing factors simultaneously to make sure airflow is sized properly. bear in mind, that same MUA unit is serving many other zones with no unmet hours.

any thoughts what can be attempted to fix this?
