Carbon dioxide can affect on human mood and working conditions in closed area. Knowledge about the level of air pollutants concentration in the room, should be a guideline to design a properly working ventilation system. For years carbon dioxide, appearing during human breathing, was not taken into consideration as a factor determining the process of ventilation systems design. At present the assessment of air quality in closed rooms is performed on the basis of measurement of concentration of carbon dioxide metabolically produced by humans that can be referred to the so-called hygienic minimum, eg the upper limit of CO₂ concentration equal to 1000 ppm (0.1%).
