Reports study of air infiltration through experimental windows installed in a normal office building. Air change rate was measured using carbon dioxide as a tracer gas. Pressure drop across window, wind velocity and direction were recorded . Finds that air leakage measured was generally quite different from that which could be calculated. Postulates reason for this is complex process caused by dynamically varying pressure differential across the window, flow occurring through window in both directions simultaneously and to particular experimental configuration used.
