Abstract (in Japanese) (See Japanese page) 
(in English) For optimizing the air-conditioning environment in a room, we have developed the air-conditioning guidance system (AC-Guide) using Raspberry Pi, to output ON/OFF instruction messages of air-conditioning equipements based on the DI (discomfort index) that is calculated from the temperature and relative humidity. Currently, COVID-19 has become the serious problem around the world. In this study, we implement the ventilation instruction function in this system to avoid the infections. The CO2 concentration in the room is measured using the sensor, and the ventilation guidance message when it exceeds the given threshold. Besides, the opening and closing of windows and doors are detected using images taken by the Web camera to confirm the ventilation action. Furthermore, the entrance and exit of a person through the door is detected using human detecting sensor and images, to improve the ventilation instruction timing depending on the number of people in the room. For evaluations, we implement the proposals on AC-Guide and confirm the validity of them.
