11/14 · The most common way for designers to comply with these requirements is a stairwell pressurization system. The premise of stairwell pressurization is pretty simple: push a bunch of outdoor air in with a fan to keep the smoke out. This allows for building occupants to evacuate the building safely. From an Architectural standpoint, there are some

The stairwell pressurization system is a mechanical ventilation system. In order to pressurize the stairs of vertical buildings, it is necessary to install sets of fans that suck air into the

However, just because the building meets the definition of a high-rise does not necessarily imply that every stairwell, or any stairwell for that matter, is required to be provided with stairwell pressurization. The code simply requires that every exit stair serving floors more than 75 feet above the lowest level of fire department access shall
