How to use NFPA 92 to design smoke control systems

摘要

When designing smoke control systems, the 2015 edition of NFPA 92: Standard for Smoke Control Systems is a standard you need to know. Historically, HVAC engineers designed these systems using spreadsheets and the prescriptive calculations in the building codes. This resulted in oversized systems having a major impact on construction costs and the building architecture, as well as unpredictable results in a real fire condition. The days of designing a smoke control system based on the volume of space as the only factor have gone away, making way for a scientific process using the latest fire science information to more accurately determine the protection needed for various smoke control scenarios.
