Learn to calculate airflow requirements for staircase pressurization system NFPA STANDARDSDownload Excelsheet from below linkhttpspassionatengineerblogs. Taking advantage of the stairwell pressurization alternative will require that a rational analysis be prepared by a qualified design professional. A stairwell pressurization system is considered a smoke control system and is subject to the many requirements of Chapter 909 in the building code.

The one used most often in North America is the stairshaft pressurization system. Assess the leakage paths through doors lifts vents. Designing such systems is complicated because an intermittent loss of effective pressurization occurs when occupants enter and leave the stairs during evacuation.

Pressurization fan makes the escape route pressurized so it forces the smoke and push it back and enables person to escape. Stairwell wall area per floor Wall Tightness.
