1. A method for determining an effective temperature set-point for one or more Variable Air Volume (“VAV”) controllers in a heating, ventilation, and air conditioning (HVAC), the method comprising:
receiving one or more dynamically sensed parameters from a plurality of sensors strategically placed within and outside of a building;
retrieving one or more static parameters corresponding to building configurations and temperature thresholds from a memory unit;
dynamically determining the effective temperature set-point for an individual VAV controller associated with a particular pre-defined zone in the building by establishing a correlation between the one or more dynamically sensed parameters and static parameters corresponding to that zone; and
receiving, with the VAV controller, the respective effective temperature set-point value and establishing the temperature set point for the associated zone based on the received value;
wherein the one or more static parameters includes the total number of sub-zones in the pre-defined zone, the one or more dynamically sensed parameters includes the sum of occupied sub-zones in the pre-defined zone, and the effective temperature set-point is based on the proportion of sub-zones in the pre-defined zone which are occupied to the total number of sub-zones in the pre-defined zone.
