Staircase pressurization systems are now specified to be installed in many types of buildings in Hong Kong. To investigate the operating performance of such a system, a series of field tests was performed. This paper reports the results on evaluating the performance of a staircase pressurization system installed in a commercial building. The measured quantities included the differential pressure levels across the doors to the staircase, airflow rate, air temperature, and fan characteristics. The airflow network program ASCOS was used to justify the results. The system was found not to be working effectively, and recommendations are made for improving the design.
