Educational buildings account for a significant share in the total building stock. Students and teachers spend many
hours every day in classrooms. For this reason, it is crucial to ensure appropriate temperature and humidity conditions
and air quality in them. This is particularly important in the case of computer laboratories, which have higher heat
gains than the average classroom. The paper presents the results of long-term and short-term measurements carried
out in the university computer laboratory of air parameters, i.e. temperature, relative humidity and speed, as well as
CO2 concentration level and thermal comfort indexes (Predicted Mean Vote and Predicted Percentage of Dissatisfied).
The research was supplemented with a survey carried out among occupants of the laboratory. On the basis of the
obtained results, it was assessed whether the natural ventilation system was efficient enough to maintain the recommended air parameters.
