The performance of schoolwork by 10-12 years old children was measured during week-long periods with improved classroom air quality (by increasing outdoor air supply rates from 6 to 20 cfm/person) and during weeks in which moderately elevated classroom temperatures were avoided (by cooling from 74 to 68 F). The results show that tripling the ventilation rate improved learning by ca. 15% while reducing the temperature also improved it by ca. 15%.
The importance of this study is that it shows that children really could perform schoolwork better if mediocre conditions in classrooms were improved, and that the improvement often be surprisingly large. Methods to improve indoor air quality without increasing energy use will be discussed.
This study was performed in Denmark funded by ASHRAE but a large scale initiative is planned to do similar studies in US.
