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.

Budynki edukacyjne stanowią znaczny udział pośród obiektów budowlanych. Uczniowie i nauczyciele spędzają wiele godzin w ciągu dnia w salach lekcyjnych. Z tego powodu kluczowe jest zapewnienie w nich odpowiednich warunków cieplno-wilgotnościowych i jakości powietrza. Jest to szczególnie istotne w przypadku sal komputerowych, które charakteryzują się większymi zyskami ciepła od typowej sali lekcyjnej. W artykule przedstawiono wyniki długo- i krótkoterminowych pomiarów parametrów powietrza przeprowadzonych w uczelnianym laboratorium komputerowym, tj. temperatura, wilgotność względna, szybkość, jak również stężenia CO₂ i wskaźników komfortu cieplnego (przewidywana ocena średnia i przewidywany odsetek osób niezadowolonych). Badania eksperymentalne zostały uzupełnione badaniem ankietowym przeprowadzonym wśród użytkowników laboratorium. Na podstawie otrzymanych wyników oceniono, czy system wentylacji naturalnej był wystarczająco wydajny do utrzymania rekomendowanych parametrów powietrza.
