Abstract
Old schools with low airtightness performance are vulnerable to outdoor fine dust. Air purifier and ventilation systems are typically used to improve indoor air quality. However, due to the noise that these systems generate, some classrooms do not operate these mechanical facilities despite the deterioration of indoor air quality. This study aimed to propose a ventilation operation method for appropriate improvement of indoor air quality through CONTAMW simulation while minimizing students' disturbance from noise from air purifier and ventilation systems. By controlling the volume of air in the air purifier and ventilation system, it is possible to minimize this disturbance in an old school and effectively improve indoor air quality.
