Buoyancy Ventilation in Multistory Buildings
Buoyancy Ventilation in Multistory Buildings
Buoyancy (or stack) ventilation is powered by heat generated inside buildings (from people, computers and so on). This Demonstration shows how to size vents at each story so that everyone gets the same flow rate of fresh air and experiences the same temperature relative to the outdoors. We consider a building with up to six stories plus an atrium. Engineering guidelines recommend a minimum of 10 liters per second of fresh air per person in an office environment.
