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.
Learning Objectives
Upon completion of this course, participants will be able to:
- Explain the stack effect and the conditions that produce positive and negative stack effects.
- Describe how HVAC equipment is integrated into mechanical smoke-control systems.
- Compare smoke-control methods, including stair pressurization, air-velocity, and exhaust methods.
- Calculate minimum and maximum pressurization requirements and door-opening forces.
- Identify the components of a stairwell pressurization system.
- Explain how fire and life-safety systems are integrated with HVAC systems.
- Describe the requirements for exit enclosures and exit pathways under the 2009 IBC.
- Explain the requirements for performance testing of stairwell pressurization systems.
Certificate of Completion
You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 24 questions. PDH credits are not awarded until the course is completed and quiz is passed.
