Recently, buildings are becoming higher and more luxurious due to the increase of urban population and development of constructional technology. High-rise buildings have many benefits in terms of efficiency and environmental friendliness such as centralizing facilities to maximize convenience. However, high-rise buildings arouse a series of new problems such as stack effect. A high-rise building contains a lofty vertical shaft, and stack effect occurs because of pressure difference between the inside and outside. On this paper, the process of application for preventing stack effect in a high-rise office building which has 39 stories above the ground level and 5 basement stories in Korea by E/Y shaft cooling system is introduced, and the efficiency on the system will be discussed by field measurement and numerical simulation(CFD).
