Abstract


The aim of this paper is to present the results of research focused on the microclimatic situation in the lecture room, seminar classroom, laboratory and large gym in the university campus. The attention is paid mainly to the problems of dimensions of space, number of students and intensity of ventilation or air-conditioning. Air temperature, relative humidity, concentration of CO2, total dust pollution and PM10 fraction were measured in the frame of this research. The recommended level of CO2 in the interior of 1,000 ppm was exceeded very significantly in all teaching rooms, only in the gym hall was lower thanks to sufficient ventilation and large volume of this space. The ventilation or air-conditioning controlled by the people was not sufficient. The solution can be the automatic control of ventilation or air-conditioning not only according to the temperature, but also with respect to the CO2 concentration. The total dust concentrations and PM10 in rooms without sufficient ventilation was over the level 50 μg·m-3. Intensive ventilation reduced the dust concentration significantly.
