Carbon dioxide is the fourth component in terms of the concentration in the air. The high concentration of CO2 influences people in the negative way. Heat gains, air humidity and the concentrations of the airborne pollutants are taken into consideration during ventilation system designing process. In the indoor pollution balances the amount of the air, which is needed to remove the excess of the carbon dioxide is much lower than one in the case of the excess of the heat. The measurements of CO2 concentration, humidity and temperature in the cinema projection room are presented in the work. The results are analyzed in relation to the acceptable indoor air quality, because the cinema auditorium is assumed to be an average indoor space.
