Field investigation was conducted to investigate the ventilation design and the indoor air quality in an academic services department of a tertiary institute in Hong Kong. Results of the study indicated that problems existed in the design, operation and maintenance of the ventilation system. Fresh air supply, though satisfying the recommended values stipulated in ASHRAE standard, was not adequate. Materials, fixtures and the ventilation system itself were found to be the dominant pollution sources according to which the required supply of outdoor air should be determined. Discussions on the design practices adopted by local building services engineers are included.
