Stack Effect

The stack effect is a natural phenomenon that occurs in buildings and structures, driven by temperature differences inside and outside. When the air inside a building is warmer than the outside air, it rises, creating a pressure difference. This causes warmer air to escape through upper openings, while cooler air enters through lower ones. This process can enhance ventilation, reduce energy costs, and improve air quality. The stack effect is particularly noticeable in tall buildings, where the height amplifies the pressure difference, and is a key factor to consider in architectural design and HVAC systems.
