PROBLEM TO BE SOLVED: To provide a control method capable of determining what control is to be implemented to air-conditioning facility in an area on the basis of a plurality of detection data in the area.SOLUTION: A control method is used in an intelligent control system including an intelligent control device and air-conditioning facility. The intelligent control device continuously records a value of CO2 content in an area after start of the air conditioning facility, and calculates a CO2 reference value on the basis of the recorded value of CO2 content, when lighting-off of a lighting fixture is detected. Then the intelligent control device continuously records the value of CO2 content in a certain time section, and calculates a CO2 comparison value in reaching the time section. Finally, the intelligent control device determines increasing tendency or decreasing tendency of the CO2 content in the area on the basis of the CO2 reference value and the CO2 comparison value, and determines to keep a present state of the air-conditioning facility, to switch to a cooling mode or air blowing mode, or to switch off the air-conditioning facility.SELECTED DRAWING: Figure 3 |
