Method and control system for controlling an air-conditioning system

A control system for controlling an air-conditioning system associated with a building for optimizing a plurality of building performance parameters in providing an environment with respect to a zone of the building, the control system comprising:

• a memory;
• and
• at least one processor communicatively coupled to the memory and configured to:
• obtain zone environmental condition information including zone temperature data associated to the zone, and cooling air temperature data associated to an air handling unit associated to the zone;
• obtain, from a zone model generator, zone cooling load parameters associated to the zone with respect to a plurality of time periods and a zone thermal dynamic model;
• obtain, from a scheduler, a sequence of optimal cool air supply rates with respect to the plurality of subsequent time periods with respect to the zone determined based on a multi-component cost function including a plurality of components relating to the plurality of building performance parameters;
• determine, based on the zone thermal dynamic model, a sequence of zone controller set-points corresponding to sequence of optimal cool air supply rates with respect to the zone using the zone cooling load parameters, the zone temperature data and the cooling air temperature data associated to the air handling unit;
• and
• send the sequence of zone controller set-points to a zone controller for controlling a temperature of the zone.
