This study evaluated IoT-based indoor air quality monitoring data collected in 118 multi-use public facilities in Gyeonggi-do such as children day care center, public medical clinics, elderly nursing home, postpartum care centers, and libraries from December 2020 to March in 2021. The average indoor concentration of PM<SUB>2.5</SUB> and PM<SUB>10</SUB> were highest at postpartum care center, and the lowest at public medical clinics. The average CO₂ level was the highest in elderly nursing home, but the difference between the daily minimum and maximum concentrations was the largest in children day care centers. As a result of time-series analysis, the concentration of PM was slightly higher on weekends than on weekdays, indicating that the air quality of these facilities is relatively well maintained during working days. The behavior of indoor particulate matters was almost similar to the outdoor air concentration. In all facilities, high CO₂ concentrations were observed during the daytime on weekdays when residents were active. During the period of this study, the average concentration of all facilities did not exceed the indoor air quality standard, but it was found to be exceeded in some places as considering the outdoor 24-hour average short-term standard excess rate (99 percentiles) method. Consequently, IoT-based monitoring is very useful for air quality management in multi-use facilities.
