Abstract
In the present study bidirectional airflow characteristics of a centre-pivot roof window were analysed in-situ. Both wind and temperature differences were present at the time of measurements. Tracer gas technique using N2O gas was used to estimate the air change rates in the experimental space. Leakages through the experimental space were estimated using the blower door tests. Air-change rates increased with increase in the window sash opening angle. When the window was open all the way, with an average wind speed of 4 m/s, the average air-change rate was 2. Flow factor was used to characterise the bidirectional airflow rates through window. The flow factor of the window increased with increase in the sash opening angle.
