Abstract

Ventilation rates and intercell airflow rates in a naturally ventilated office building have been determined using multiple tracer gases. To do this, the building was subdivided into three zones and each zone was then seeded individually with one corresponding tracer gas. The time histories of the concentrations of all gases in each zone were then monitored using non-dispersive infrared gas analysers. The airflow rates were then calculated from the experimental data. Using these calculated values, a computer programme written in-house to predict the dispersion of a tracer gas in a multi-zoned environment was validated by comparing the predicted time histories of concentrations with those obtained from experiment.
