Furthermore, an industrial flue gas stack typically provides little obstruction for the flue gas along its length and is, in fact, normally optimized to … See more The stack effect or chimney effect is the movement of air into and out of buildings through unsealed openings, chimneys, flue-gas stacks, or other containers, resulting from air buoyancy. Buoyancy occurs due to a difference in … See more Two regimes of stack effect can exist in buildings: normal and reverse. Normal stack effect occurs in buildings which are maintained at a higher temperature than the outdoor environment. Warm air within the building has a low density (or high specific volume) … See more • HVAC (heating, ventilation and air conditioning) • Ventilation shaft • Solar chimney See more • Stack Effect: When Buildings Act Like Chimneys --Green Building Advisor • National Research Council Canada - CBD-104 Stack Effects in Buildings • Stack effect simulation on YouTube See more Since buildings are not totally sealed (at the very minimum, there is always a ground level entrance), the stack effect will cause air infiltration. During the heating season, the warmer indoor air rises up through the building and escapes at the top either through … See more There is a pressure difference between the outside air and the air inside the building caused by the difference in temperature … See more The draft (draught in British English) flow rate induced by the stack effect can be calculated with the equation presented below. The equation applies only to buildings where air is both inside and outside the buildings. For buildings with one or two floors, h … See more

WebNov 26, 2024 · The stack effect is the natural vertical airflow through a home. It’s also what makes a fireplace work by drawing air in, helping the fire come to life, and then rushing out the chimney. Unfortunately, the stack effect in your home can also generate several undesirable phenomena. In the winter cold air enters your home’s basement or crawl ...
