Stairwell Pressurization Systems
This online engineering PDH course provides a comprehensive overview of stairwell pressurization systems in high-rise buildings.
In high-rise buildings, the stairs typically represent the sole means of egress during a fire. It is imperative for the stair exits to be free of smoke. Most building codes require the fire stairwells in a high-rise building to be pressurized to keep them clear of smoke. This should happen while operating at a low enough pressure that an average person can open the doors and 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 5 PDH online course is applicable to HVAC engineers, architects, loss prevention engineers, facility maintenance personnel, environmentalists, energy auditors as well as consultants and contractors involved in the construction and management of high-rise buildings.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the requirements of fire, life safety and HVAC equipment in relation to smoke control
- Explaining how heat affects smoke movement in a high-rise building
- Defining stack effect and explaining the conditions necessary for positive and negative stack effect
- Knowing how to integrate HVAC equipment into mechanical smoke control systems
- Explaining smoke control methods, stair pressurization, air velocity and exhaust method
- Explaining the minimum and maximum pressurization requirements as well as door opening force calculations
- Explaining the components of pressurization and their functionalities
- Understanding the codes and standards that govern design of stairwell pressurization systems
- Understanding the design methodology and calculating the airflow requirements for maintaining the pressure limits
- Learning to integrate fire and life safety systems with HVAC systems
- Understanding the requirements of exit enclosures and pathways that must be addressed to be in compliance with the new 2009 IBC
- Understanding the requirements of performance testing
Once you complete your course review, you need to take a multiple-choice quiz consisting of twenty five (25) questions to earn 5 PDH credits. The quiz will be based on this course document.
