A heating, ventilation, and air conditioning (HVAC) system configured to provide a perceived comfortable ambient environment to an occupant seated in a vehicle cabin, said system comprising: a first nozzle configured to direct a first air stream from the HVAC system; a servo mechanism coupled to the first nozzle configured to articulate the first nozzle in order to direct the first air stream to a desired location; characterized in that the HVAC further comprises a controller in communication with the servo mechanism, said controller configured to identify a sensitive portion of a body of the occupant that is more sensitive to heat loss than other portions of the body, determine an ambient temperature of the vehicle cabin, determine a desired heat supply rate for the sensitive portion, wherein the desired heat supply rate includes a steady-state heat supply rate based on a difference between a comfortable heat loss rate for the sensitive portion and an actual heat loss rate for the sensitive portion at the ambient temperature; determine a comfortable skin temperature for the sensitive portion, determine a flow rate for the first air stream and a stream temperature for the first air stream based on at least the desired heat supply rate, the comfortable skin temperature, a discharge area of a nozzle, a dispersion angle of the nozzle, and a distance from the first nozzle to the sensitive portion, determine a location of the sensitive portion, and operate the servo mechanism to articulate the first nozzle in order to direct the first air stream to the location of the sensitive portion, said first air stream configured to have the stream temperature and the flow rate necessary to establish the desired heat supply rate for the sensitive portion. a first nozzle configured to direct a first air stream from the HVAC system; a servo mechanism coupled to the first nozzle configured to articulate the first nozzle in order to direct the first air stream to a desired location; characterized in that the HVAC further comprises a controller in communication with the servo mechanism, said controller configured to identify a sensitive portion of a body of the occupant that is more sensitive to heat loss than other portions of the body, determine an ambient temperature of the vehicle cabin, determine a desired heat supply rate for the sensitive portion, wherein the desired heat supply rate includes a steady-state heat supply rate based on a difference between a comfortable heat loss rate for the sensitive portion and an actual heat loss rate for the sensitive portion at the ambient temperature; determine a comfortable skin temperature for the sensitive portion, determine a flow rate for the first air stream and a stream temperature for the first air stream based on at least the desired heat supply rate, the comfortable skin temperature, a discharge area of a nozzle, a dispersion angle of the nozzle, and a distance from the first nozzle to the sensitive portion, determine a location of the sensitive portion, and operate the servo mechanism to articulate the first nozzle in order to direct the first air stream to the location of the sensitive portion, said first air stream configured to have the stream temperature and the flow rate necessary to establish the desired heat supply rate for the sensitive portion.
