Adequately designed natural ventilation is the cheapest and easiest way to effectively remove indoor pollutants and keep the fresh air inside a building. A prediction of performance and effectiveness of ventilation in order to determine the design of a ventilation system can provide real and long term cost savings. The paper presents results of performance (air change rate ACH) and effectiveness (CO2 concentration in the breathing zone and temperature distribution ) of natural ventilation for a building with inlet gap measured for the transitional season (between the heating and the summer season). The measurements were performed during a windy period. The test apartment was located in cold climate. The measurement system measured local climate conditions, indoor climate conditions and air velocities in both vent inlet and outlet.
