Understanding the Stack Effect and Building Ventilation

Read captions for more details👇 . The stack effect in the context of fires operates on the same principles as water flowing through a pipe, but with air moving up a chimney or through a building. When a fire heats the air, this hot air becomes less dense and rises, creating a draft. This upward movement of hot air creates negative pressure at the base, drawing in cooler air from outside to feed the fire with more oxygen. As the fire grows hotter, the draft becomes stronger, pulling in even more
