Abstract: The invention involves an air distributing apparatus for installation in a diffuser. The apparatus includes a first damper positioned within the diffuser. The first damper also has an open mode where a stream of air can exit the diffuser to a space. The first damper has a closed mode where the damper inhibits the stream of air from exiting the diffuser. The apparatus includes an actuator operatively connected to the first damper. There is an occupancy sensor positioned and configured to distinguish whether the space is occupied or unoccupied by a person. The occupancy sensor is in communication with the actuator. When the space is occupied by the person, the occupancy sensor communicates with the actuator to thereby cause the first damper to be positioned in the open mode. When the space is unoccupied, the occupancy sensor communicates with the actuator to thereby cause the first damper to be positioned in the closed mode.
