Summary

The constant-injection and pulse-injection tracer-gas techniques were used to measure air flow in air handling units and to estimate flow rates supplied to each floor. Tracer-gas measurements were compared with measurements made using a Pitot-static tube. Air exchange rate, ventilation efficiency and age of air were examined. The concentrations of carbon dioxide, carbon monoxide, formaldehyde and dust particles were monitored. In addition, a questionnaire was completed by library staff and users in order to provide a subjective assessment of indoor air quality.
