This study investigated user behaviour in the operation of doors, windows and fans in classrooms and their relationship with thermal performance and natural ventilation, as well as validating a predictive model for window status. Environmental variables and the status of the systems were monitored in three classrooms at a school in Campinas. During the cold season, the classrooms maintained adequate temperatures and humidity most of the time, but closing the windows impaired ventilation and increased CO2 concentration at times. In the hot season, 54% and 29% of the occupied period had thermal and humidity conditions outside acceptable limits, respectively. The validation of the predictive model performed well. Future research could improve the accuracy of the models by expanding the data and optimising thermal control and ventilation strategies, aiming for more comfortable and healthy learning environments.
