Abstract
The urban environment has been changing rapidly, and with buildings becoming larger, denser, and more complicated, parking lots have gradually been moved underground. The consumption pattern of vehicles has changed from compact to mid- or full-sized cars, and the risk of car fires has also increased with the use of more flammable materials in cars to improve fuel efficiency. Consequently, the necessity of smoke control applications in underground parking lots has become essential to ensure fire safety. Smoke control partition areas were set to 5000 m<sup>2</sup>, 3000 m<sup>2</sup>, and 2000 m<sup>2</sup>, to analyze the performance of smoke control facilities in underground parking lots. The flow rate of smoke control was set to 18 CMH and 27 CMH and compared with the duct installation setup. The results showed that smoke control performance was most suitable when the smoke control partition area was set to 3000 m<sup>2</sup>, the flow rate of the smoke control was 27 CMH, and the duct was installed.
