Abstract

Results of an indoor environment survey in a large underground car park in Hong Kong are reported in this paper. Field measurements were divided into three parts: (1) assessment of the thermal environment; (2) measurement of the carbon monoxide concentration; and (3) a survey on thermal comfort. The indoor air temperature, relative humidity, instantaneous air speeds, turbulence intensity, and carbon monoxide concentration at different locations in the car park were measured. Design and operation of the installed ventilation systems were studied and the number of cars staying at the car park was investigated. Correlation relationships between the mean carbon monoxide and the mean air speed, the turbulence intensity, and the number of cars entering or leaving the car park were derived. Field studies of this kind are very important for providing ventilation system design data.
