In Stairwell Pressurization Systems, you'll learn ...

  • The requirements of fire, life safety, and HVAC equipment in relation to smoke control
  • How heat affects smoke movement in a high rise building
  • The codes and standards that govern design of stairwell pressurization systems
  • The design methodology to calculate the airflow requirements for maintaining required pressure limits

In high-rise buildings, the stairs typically represent the sole means of egress during a fire. It is imperative for the exit stairs to be free of smoke. Most building codes require the fire stairwells in a high rise building to be pressurized to keep the stairs clear of smoke. This should happen while operating at a low enough pressure that an average person can open the doors to exit the stairwell on their way to safety.

Smoke management assumes particular significance in high rise buildings because the time necessary for evacuation may be greater than the time for the development of untenable smoke conditions on stair cases. Smoke needs to be managed and its prevention and mitigation should be an essential part of any HVAC design.

This 4 hour course provides a comprehensive overview of stairwell pressurization systems. This course is applicable to HVAC engineers, architects, loss prevention engineers, facility maintenance personnel, environmentalists, energy auditors as well as consultants and contractors who construct, build and manage high rise buildings.
