Air quality in a classroom is very important. According to a study by Wargocki et al (2012) a shortage of ventilation in the classroom reduces the ability of students to concentrate and causes an increase in the number of errors during the elaboration of tasks. The aim of this study was to contribute to the optimization of acquisition and operating costs of HVAC equipment and to ensure hygienic requirements of air quality in the indoor environment for classrooms.

This study aims at investigating the actual conditions of indoor environment in schools in order toobtain fundamental information for proper ventilation design of buildings. Indoor environment of twonew elementary schools in Tohoku district of Japan was investigated for a week in the winter 2005.Temperature and humidity, concentrations of Carbon Dioxide (CO2), ventilation airflow rates,concentrations of chemical substances, and the opening condition of the windows and doors weremeasured in the three classrooms of each school.
