Learning objectives:. 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. As a standard, NFPA 92 is a document that is referenced by other codes for application purposes.

We design these systems with confidence by relying on engineering principles that have been experimentally verified. The CD contains programs that can be used for design calculations related to smoke management systems, according to Klote. The book provides information on pressurized stairwells, pressurized elevators, zoned smoke control and smoke management in atria and other large spaces.
Recent advancements include heat release rate, toxicity of smoke, natural atrium venting, plugholing, minimum depth of an atrium smoke layer, smoke stratification, smoke detection, tenability systems and computer analysis. Designers need to understand these engineering principles to design successful systems and to avoid repeating the same mistakes of those who came before them, Klote said. I want to hear from you. Tell me how we can improve.
