The paper is oriented on the problems of heating and ventilation in small university lecture hall. Providing the optimal parameters of thermal comfort is immensely important for students of university in small university lecture hall. Incorrectly functioning heating and ventilation can disrupt thermal comfort. Reconstruction took place in small university lecture hall. The original windows were exchanged for modern wood tight windows. Experimental measurements were carried out in winter season in 2016 in this small university lecture hall, in order to evaluate the thermal comfort and CO2 concentration after the reconstruction. The device Testo 480 was used for measurements. Obtained values of air temperature, air relative humidity, air velocity, globe temperature, indexes PMV, PPD and CO2 concentration are presented in the graphs. Heating, ventilation and operation of small university lecture hall were evaluated on the basis of parameters of thermal comfort and CO2 concentration. Principles how to design the heating and ventilation in small university lecture halls are in the conclusion of the paper. Furthermore, there are presented recommendations how to operate the heating and ventilation in existing small university lecture halls.
