Smoke Exhaust and Fire Suppression System
A smoke exhaust system was designed to reduce typical
over-engineering inherencies by reducing fan horsepower from 100 to 25
horsepower and lowering the exhaust air flow from 100,000 cfm to 40,000
cfm in a high school atrium. A test fire was modeled at the base of the
atrium stairs with corresponding building fire automation system
sequences simulated to ensure occupant safety and visibility in the
event of a fire emergency. Smoke tests of the evacuation system,
completed after construction was finished, indicated that the smoke
evacuation system performs as modeled while reducing mechanical costs
and , most importantly, effectively mitigating smoke without impeding
student movements.
