Apartment occupants have a major impact on indoor air quality. Indoor air pollution includes water vapour, carbon dioxide and other gases due to respiration and bodily odours. Negative impact they have from brought in by clothing and footwear or becomes whirled up from floors, carpets etc. In this article presents the experimental measurement of indoor air quality, mainly concentration of carbon dioxide, air temperature and relative humidity. Indoor air parameters are recorded during 24 hour per every day the all week. Measurements take place was exercised in these rooms: living room, children rooms, kitchen, bathroom and corridor. During the measurements the investigated room was occupied by different persons regarding the sex, age and weight. Measurements were carried out during a sedentary work using computer and other home works. The main result of this research is the monitoring of indoor air in the apartment for, calculation of uncontrolled ventilation of rooms, which is caused leaks through building structures. The resulting values, calculated of uncontrolled ventilation rate, it will be possible to use for in determining the needed ventilation rate for the achieving needed air quality. From The graphic illustrations concentration of carbon dioxide, is possible observe real course the concentration of carbon dioxide in the apartments during their use. From measurements is possible conclude, whether in the apartment, during its use, occur there the over limit values of pollutants.
