The use of energy for operating ventilation systems in underground car parks in Hong Kong is considered. A site survey has been carried out in 22 underground car parks. The physical size, configurations, and electrical rating of ventilation fans were the main matters of interest. The indoor thermal environments, carbon monoxide concentrations, and operation of ventilation systems were examined. Mathematical expressions are developed and the predicted results examined for another 54 underground car parks. The results show that significant savings can be achieved if a two-level ventilation strategy is implemented.
