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.

Natural smoke ventilator is one of domestic prescriptive methods to be used to exhaust smoke in case of fire in a high-rise buildings. The goal of this study is to evaluate the stack effect and the smoke exhaust performance in high-rise buildings with the opening of natural smoke ventilators using computer modeling technology, thus to estimate its effectiveness as a tool of smoke exhaust. For this purpose, the pressure differential in a domestic high-rise building with natural smoke ventilators was experimentally measured to analyze the stack effect with the closure or the opening of natural smoke ventilators and to calculate compensated air leakage of the building. Computer modeling based on experimentally measured data was carried out to estimate effectiveness of natural smoke ventilators in high-rise buildings using CONTAMW network program.
