Abstract
This study aims to suggest ventilation design data for Public Entertainment Facilities in relation to Indoor Air Quality. The concentration of indoor air pollution such as CO, CO2, RH, Radon, HCHO, TSP was investigate, and the reguired ventilation rate of Public Rooms was calculated. As resuits of this study, the following conclusion could be obtained. Field measurement of P.E.F reveals that the concentration of CO2 was mist polluted and higher than IAQ standard, while that of other pollutats did not exceed the standard. In underground the concentration of CO2 increased 1130ppm(2 persons) 2170ppm(4 persons) 1970ppm(6 persons). The CO2 pollution was serions problem in underground more than second floor, in only exhaust ventilation system more than exhaust and supply system.
