A variable-air-volume (VAV) conditioning system having at least one diffuser (27a-27d), a flow control element (53) movably mounted for control of the volume of supply air (SA) discharged from the diffuser (27a-27d). The VAV system also includes an air induction nozzle (50,58) mounted to induce room air (RA) flow over a room air temperature sensor (28a, 28a′) which controls movement of the flow control element (53). The induction air nozzle (50,58), however, is fluid coupled to a ventilation air assembly for the discharge of ventilation air (VA) into the rooms (22a-22d). Preferably, the induction air assembly is provided by a ventilation conduit assembly (44, 46a-46d) and a ventilation air treatment and supply assembly (41) fluid coupled to a ventilation air source. The ventilation air is discharged through the air induction nozzles (58). A method for ensuring the flow of ventilation air (VA) into a room (22a-22d) including the step of discharging ventilation air through an air flow induction nozzle (50,58) so that ventilation air flow is controlled independently of and decoupled from the variable flow rate of supply air from the central air conditioning supply air source (23).
