고층 주거건물에서 연돌효과 저감대책-샤프트 냉각법

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. The main purpose of this study is to analyze the nature of stack effect in high-rise residential buildings and investigate the reduction strategies with network simulation. The simulation has been conducted for 2 high-rise buildings under the construction which have 36, 37 stories above the ground level and 2 basement stories respectively by CONTAMW. An additional analysis for shaft cooling method is discussed with ESP-r simulation. In this paper, the results of pressure difference, the location of the neutral plane and air-flow between the spaces for analyzed cases will be presented. Further, the control method to minimize the stack effect will be discussed.
