+**Stack effect** is the natural movement of air within a building, driven by differences in indoor and outdoor temperatures. This thermal buoyancy causes warmer, lighter air to rise, creating [Pressure](/wiki/pressure) differentials that pull cooler air in from lower levels and push warmer air out from above, significantly impacting [Ventilation](/wiki/ventilation) and energy efficiency.
