The purpose of this case study is to analyze stack effect problems and to develop the method minimizing stack effect in the tall complex building in the winter season. The main problems in tall complex building occur in high-rise elevators. Such problems in the elevator doors that do not close or exhaust air flows result in excessive pressure difference across elevator doors due to stack effect. Under the expected conditions causing the pressure difference, computer simulations with CONTAMW computer program and field measurement were performed in tall complex building. The results were analyzed by architectural design aspects. With those analyses, we suggest the tall complex building design guidelines to minimize stack effect.
