AbstractThe stack effect creates uncontrolled vertical air movement in buildings. This air movement over the building envelope and internal parts of the building creates noise and draft through gaps of doors and increases energy consumption. The wind and mechanical ventilation may also have a pronounced effect on the air pressure conditions and the movement of the air along the shafts of the building. The objective of this study was to find solutions to minimize the stack effect. The effects of air tightness, air leakage distributions, and outdoor environmental conditions on air pressure conditions and energy consumption in a high-rise residential building were simulated in cold climate conditions. The stack effect is possible to prevent with spatial arrangements and improved air tightness. Based on the analysis carried out, internal air tightness is playing the major role in the control of the stack effect.
