Abstract: An air movement system (10) is provided which comprises at least one fan (40), a plurality of exhaust (70) and/or supply points connected to the at least one fan by ducting (50), a plurality of dampers (80) each associated with at least one exhaust and/or supply point for regulating air flow through it, a plurality of sensors (90) each associated with at least one exhaust and/or supply point for sensing a predefined activity within a predefined locale of the at least one exhaust and/or supply point, and a programmable controller (120). The controller is connected to the fan, the dampers and the sensors, and is configured to automatically adjust a damper associated with an exhaust and/or supply point, and adjust the at least one fan, in response to a signal generated by a sensor associated with the same exhaust and/or supply point.
