The effects of moderately raised classroom temperatures and classroom ventilation rate on the performance of schoolwork by children

For that study, two independent field experiments were carried out in shool classrooms. The air temperature was modified either by operating or idling split cooling units installed in that aim. For one of those experiments the outdoor air supply rate was manipulated too. The conditions were established for one week at a time in a blind crossover design with repeated measures on two classes of 10 to 12 year old children. During exercices, pupils indicated their environmental preceptions and the intensity of any symptoms on visual analogue scales. Results are presented, they show that providing some means of avoiding elevated temperatures would improve educational attainment
