Case Study of Analysis of Problems and Minimizing Methods of Stack Effect in the Tall Complex Building

초고층 복합건물의 연돌현상 가중요인과 저감방안 사례연구

The purpose of this case study is to analyze stack effect problems and to develop methods minimizing methods of stack effect in the tall complex building in cold climates. The main problems in the tall complex building occur in high-rise elevators. Such problems as elevator doors that do not close and exhaust airflows result in excessive pressure differences across elevator doors due to stack effect. Under the expected conditions causing these pressure differences, computer simulations with CONTAMW computer program and field measurements are performed in the tall complex building. The results are analyzed in architectural design aspects. With these analysis, the tall complex building design guidelines to minimize stack effect are proposed.
