Which term describes smoke control using building design and barriers without relying on power?

Passive smoke control is achieved through the building’s design and barriers rather than any mechanical system. It relies on features like fire-rated walls and doors, compartmentalization, and properly sealed openings to slow, trap, or direct smoke without using power. This means smoke movement is governed by the structure itself and the natural behavior of hot gases, so the system remains effective even if power fails or HVAC equipment isn’t running. Zoning or compartmental design can help limit spread, but the term described here specifically emphasizes smoke control that operates without active equipment. Pressurization involves fans and ventilation to move smoke, which uses power, so it isn’t passive. Opposed air flow isn’t a standard approach for passive smoke control.
