Abstract In order to present the operation plan of the classroom in response to COVID-19, the change in air environment measurement value of classroom was visualized through trend analysis and quantitatively assessed to provide students with air environment status of classroom in real time so that efficient window-opening environmental control action can be carried out. It was found that as a result of visualizing the amount of change in air environment, it is possible to clearly understand the change trend and the magnitude of change in CO2 concentration. In addition, the concentration of PM10 indicates the trend of maintaining a certain value during class, and the concentration of PM2.5 also indicates the trend of maintaining a stable constant value. And It is useful for quantitatively analyzing changes in air environment as it can quickly and clearly indicate changes in air environment through trend analysis and process & plan of window opening operation in classroom was suggested.
