Abstract In this study, the effect of window opening, which is a control mechanism for air control in winter high school classrooms, on the change in air and indoor environment of the classroom was analyzed and physical conditions of indoor and air environment were observed during the classroom course, and satisfaction of the students and teachers was assessed with questionnaires. And the changes in air environment were assessed by the performance of the duster cleaning work in the classroom. It was found that 84.6% of the students surveyed said the air was stuffy. And among the alternatives, opening windows all times during class was most effective in reducing CO2 concentration and PM concentration was measured within classroom's standard. In addition, the concentration change rate of duster cleaning work was reduced by 74.4% and 65.4% of PM10 compared to broom cleaning work.
