Designing Roofs for Life Safety and Sound Isolation

This course explores the application of sound-rated smoke vents to isolate exterior noise and protect the acoustic performance and comfort of the interior space. Various metrics used to measure sound-buffering performance will be compared. An overview of the building and life safety codes that require the use of these automatic smoke vents will also be discussed and the benefits of these life safety devices will be summarized. Projects where these acoustical smoke vents have been installed are also profiled.

Learning Objectives

  1. Summarize how automatic smoke vents work in response to a fire event and how they modify the way that a fire progresses through a burning building.
  2. Select the appropriate noise-measuring metric to evaluate the sound-buffering performance of building facade products that need to mitigate noise made from airplanes, construction activities, and traffic.
  3. Explain the ways that automatic smoke vents are required to be incorporated into a design by the standard NFPA 204, authored by the National Fire Protection Association (NFPA), the 2018 International Building Code, and the International Fire Code (IFC).
  4. Describe the many ways that automatic smoke vents offer better protection for people, firefighters, and property in the event of a fire.
