Investigation of IAQ in Mechanically Ventilated Kindergartens and Elementary Schools in Korea

Hyeun Jun Moon, Seung Ho Ryu, and Jeong Tai Kim
Abstract—This study investigates the indoor pollutant levels in school buildings according to the operation of mechanical ventilation system. Three classrooms at two different elementary schools and four classrooms at two children’s day care center in Korea were chosen for investigation of indoor air quality with mechanical ventilation systems. Measurements were conducted for particulate matter, formaldehyde, total volatile organic compounds, carbon monoxide, carbon dioxide, nitrogen dioxide, ozone, radon, and total bacteria counts. Differences in indoor pollutants concentrations with and without operation of ventilation systems in each classroom were analyzed. The results show that operation of ventilation systems could decrease the levels of indoor pollutants in the classrooms, especially showing the reduction of HCHO concentrations by 14.9–62.3%.

Index Terms—Day care centers, elementary schools, indoor air quality, ventilation system.
