Purpose: Domestic buildings are trending not only towards being taller and larger, but also towards going underground. This paper presents an experimental study conducted to support the improvement of the performance of automatic pressure control dampers, considering the actual evacuation situations of occupants. Although the design standard stipulates that one exit door may be opened for buildings with 20 floors or fewer, and two exit doors may be simultaneously opened for buildings with more than 20 floors, this experiment was performed with a focus on real-world evacuation scenarios. Method: We investigated and reviewed domestic fire protection targets for residential buildings, examined domestic and international papers, policies, and regulations, and selected a 16-story residential building for experimental analysis of the product developed in this study. Result: The performance of the developed automatic pressure control damper was verified in real field conditions, and the results were derived from the findings. Conclusion: In this study, we confirmed that the improved performance of the automatic pressure control damper can achieve effective smoke control air velocity, even when multiple floor exit doors are simultaneously opened during the evacuation of occupants in real-life situations.
