PROBLEM TO BE SOLVED: To restrain the deterioration in indoor heating circumstance by a method wherein a ventilating function unit is controlled based on the amount of ventilation, in which an indoor CO2 concentration becomes the reference value of CO2 , concentration, operated respectively at the finishing time point of respective receiving times based on the estimated value of the receiving time as well as the generating amount of CO2 , and the reference value of CO2 concentration. SOLUTION: Data in an objective room, in which the receiving time of multitude of persons in a utilizing period of time including a time to rest is set, such as the teaching room of a school, for example, or the estimated value of generating amount of CO2 and the number of receiving persons in respective times to rest and respective receiving times as well as the reference value (1000 ppm) of the CO2 concentration are stored in a capacity operating unit 2. When the objective indoor or the teaching room is ventilated, the amount of ventilation, which obtains the reference value of CO2 concentration in the teaching room at the finishing time of teaching hours, is operated based on the estimated value of generating amount of CO2 with respect to the teaching hours and the reference value of CO2 concentration while the ventilating function unit 1 is controlled based on the operated amount of ventilation.
