This paper, released by the Fraunhofer, Institut für Bauphysik – IBP, reveals that many schools across Europe do not provide an adequate indoor environment for their students; they fail to provide a sufficient outdoor air supply rate and are too warm in the summer months. The findings of the study report excessive levels of CO2, above the recommended range of 1,000 – 2,000 ppm, together with inadequate levels of daylight.

The researchers found that improving ventilation rates, reducing CO2 concentration and increasing access to daylight in classrooms, improves students’ performance in the sense of speed, higher levels of attention and concentration and lower rates of absenteeism. They stress that a good design for successful natural ventilation is important – independently of the presence of a mechanical system – combined with a daylight-responsive, occupancy related control of lighting in classrooms.
