In general, any changes to room temperature for energy savings should not impact the occupants' thermal comfortability.Therefore, the thermal control strategy should meet the occupants' thermal comfortability expectations while exploring the energy consumption reduction strategy.The paper presents our preliminary work in developing "people-centered" energy-saving methods.The work starts with building a CFD thermal dynamic model of the room by using an actual kitchen as the prototype.The model can simulate and derive the temperature at any position within the room space and capture its temperature dynamics.Then, a targettracking people-centered control strategy is proposed.With the occupant's motion and position changes, the model can calculate the room temperature at the point where the occupant is located.The objective of the control is to ensure the occupant's thermal comfortability.The initial simulation study indicates that the target-tracking control strategy could potentially save 23.32% more energy and greatly enhance the occupant's thermal comfort compared to a fixed-position sensor-based control strategy.
