“…The numerical results were compared with the experimental ones [24]. The experimental tests were carried out in 22 identical residential houses standing in one row, located in Germany by Leipzig [2].The residential area of the medium-size house was 114 m 2 , where the area of 102 m 2 was the heating area.…”

The infl uence of the CO 2 concentration in a local air zone in naturally ventilated residential houses on the residents' behaviour was numerically investigated. A numerical two-dimensional CFD model of the indoor zone based on experiments performed by the authors was used. Different resident locations in the fl uid domain and different inlet velocities imposed by wind were considered in simulations. The overall thermal comfort and IAQ indices were also calculated. The investigations results show that in contrast to the overall air quality, the local CO 2 was strongly dependent upon the resident location, fresh air inlet velocity and ventilation system type.
