Aspects of the invention are directed towards a system and a method of controlling temperature of different zones inside premises based on determining an effective temperature set point. One or more dynamically sensed parameters are received from a plurality of sensors strategically placed within and outside of a building. One or more static parameters corresponding to building configurations and temperature thresholds from a memory unit are retrieved. A correlation engine determines the effective temperature set point for 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. The effective temperature setpoint is transmitted to a VAV controller for associated zone.
