Finding F-1653

“Potential benefits were found on speed and accuracy of tasks of cognitive performance when indoor temperature was set between 20 and 23oC and at CO2 levels of 600 ppm compared to higher temperatures and poorer ventilation rates and that both ventilation and thermal environmental control are important and need to be improved for achieving optimum learning conditions.”

Structure

Factor: Carbon dioxide (CO₂)
Outcome: Cognitive performance
Setting: classroom
Study design: field study in classrooms with multivariable multilevel regression: indoor temperature and carbon dioxide, as markers of the ventilation rate, related to the speed and accuracy of cognitive tasks after adjustment for confounders (class 4)
Effect: difference
Caveat: the study says the result is relevant for short-term exposure, and temperature and ventilation cannot be separated in it
