Abstract

The present work is aimed to investigate the possible transmission mechanisms of the air cross-contamination in one typical high-rise residential building in Hong Kong. The experiments were performed in a wind tunnel using 1:150 scale model that represented real structures. Tracer gas was continuously released from point source at different positions. A series cases were conducted during the experiment to consider the effects on pollutant dispersion behavior of changes in source position and upcoming wind condition. Mean concentrations were measured using fast flame ionization detectors. The experiment results illustrate that in case of accidental release of toxic or highly infectious diseases outbreak in high-rise residential building, the cross-contamination within the building environment could not be overlooked, and its risks at different circumstances were compared and analyzed.
