In this paper, the field measurements results are presented on the stack ventilation effect. The paper presents the results of performance (air change rate ACH) natural ventilation for building with inlet gap measured for the transitional season (between heating and summer season). The measurements were performed during a windless time. The house was located in northern Poland, in a cold climate region. The measurement system measured local climate conditions, indoor climate conditions and air velocities in vent inlet and outlet. In this paper, the discharge coefficient was checked. The discharge coefficient of 0.83 was higher than the discharge coefficient of 0.6 which was usually assumed for small rectangular openings during the natural ventilation. In a wind absence when the stack effect acted only, the air change rate (ACH) slightly exceeded the standard minimum value.
