of heating, ventilation and air conditioning system

When the present invention is a method for controlling the energy (Heating, Ventilation, and Air Conditioning) HVAC system, determines the user is absent if the space for energy control in the process and, the user is absent is determined, stored is collected in advance If it is determined to start the user of the out and home process, energy control for determining the occurrence probability, and whether or not to utilize distribution of out length energy control start extracted based on the data, the pre-collection defined in advance based on the stored data, extracting a time probability distribution of the length of each going out the occurrence probability and the time interval by the generated out interval, and selecting a time interval to perform the energy control on the basis of the user arriving probability calculation based on the extracted probability distributions the step of calculating a target temperature for the selected time interval, the line The time period and a process of setting up a schedule to perform the energy control according to the target temperature, the calculated.
