Abstract

The concept of the fire-resistant building is promptly discussed while designing and incorporation mechanical systems into the building, while smoke management is deeply forgotten in the initial stages and even in later stages of equipment installation. Although, it is a well-established fact that smoke is more dangerous to life and life-taking than a fire during a fire in a building. In this study, active and passive methods like a smoke purge, pressurization control, smoke reservoirs, etc. of creating a building smoke proof are discussed. Also, factors influencing these active and passive measures like buoyancy, stack effect, etc. are discussed, and how to calculate the implication of these factors are assessed. The design guideline from different codes like NFPA 92, NFPA 92A, NZBC C3/AS 1530.4, BS 476 part 24, ISO 5925/1, design of smoke management systems for buildings published by ASHRAE, are reviewed for smoke management, and analysis of most relevant and new research in the field of smoke management systems that demonstrates significant evolution in the field. The idea of the smoke-resistant building can be easily achieved if incorporated in the early stages of design, even if applied with proper technique and equipment can also be achieved in later stages.
