A common control strategy for the cooling supply air temperature in VAV reheat systems is warmest zone reset.

SetpointManager:Warmest resets the cooling SAT based on the cooling demand of the warmest zone, at the maximum zone supply air flow rate.

This strategy is used to minimize the amount of reheat that will occur at the zones. VAV reheat systems typically supply air to the zone at 55F to 60F, then will reheat the air up to 95 F at the zone level for zones that require heating. However, if most zones are in heating mode, than it is beneficial to reset the supply air temperature to a higher value so that it minimizes the amount of reheat and resulting heating energy.

Assuming that you are in a climate that requires heating at some point in the year, it makes sense to me that if you are supplying 55F air all year round you will see very high heating energy from reheat. Applying a reset to the SAT will absolutely yield significant heating savings.
