Conclusions

 

  • The comfort assessment was a useful tool for collecting information from the children about their perception of the school environment.
  • Objective measurements of temperature, relative humidity and CO2 strongly supported the children’s subjective perceptions.
  • Among the most interesting findings were that:
    • 48 percent of children thought that their classroom was warmer than optimal (above 22°C was considered too warm), a finding that may be significant in terms of energy saving;
    • good air quality during the lessons significantly depended on the ventilation regime during the breaks, and although there were significant differences in perceptions of air quality during the breaks between classrooms, corridors and schoolyards, most of the children (41 percent) still spent their breaks inside the classrooms; and
    • significantly more children had headaches among those who felt the air quality to be bad (27.2 percent) or neutral (20.9 percent) than among those who felt the air quality to be good (16.9 percent). After adjustment for gender and age, logistic regression analysis showed that in the case of bad air quality the risk of headaches increased by 96 percent, and even in the case of neutral air quality by 31 percent, compared to good air quality.
