Résumé

Present study examined how different types of ventilation systems influence classroom temperature and air quality, and whether there is any impact on window opening behaviour of pupils and teachers. Five classrooms were selected in the same school located in rural Copenhagen with different methods of ventilation obtained as follows: by manually operable windows, by automatically operable windows with and without exhaust fan, and by balanced mechanical ventilation system. Measurements were performed in the selected classrooms during non-heating season in May when outdoor temperatures were 10-30? (during school hours). The results show that the thermal environment can be better controlled in the classrooms with balanced mechanical ventilation system and with automatically operable window with exhaust fan. The classrooms with these systems had lower carbon dioxide levels and thus better air quality. There were no considerable differences in window/garden door opening behaviour. Present results need confirmation in the heating-season. The experiments are on-going to collect these additional data.
