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).

The stack-effect in high-rise buildings in winter causes many problems such as difficulties in opening or closing doors, infiltration, energy loss, noise and fire protection. Stack effect is influenced by temperature difference between the interior and exterior of building and the height of building. As an attenuation method for stack effect, the architectural methods are generally used. However, as though architectural methods were fully adopted, the problems are reported as ever in tall building. In this study, a new method to reduce stack effect will be suggested. As an active control method against the stack effect, E/L shaft natural cooling method is suggested. In this paper, the concept of E/L shaft natural cooling system and its reduction performance of stack effect by CFD simulation will be reported.
