Smoke management for covered malls and atria

This paper provides an overview of the principal design considerations of smoke management systems for covered malls and atria included in a recently proposed technical guide. The engineering basis for formulating an appropriate design for a smoke management system is presented in the form of algebraic equations and graphs. Techniques to assess the level of life hazard created by a fire in an atrium or covered mall with a smoke management system are discussed. The level of life hazard is expressed in terms of the following hazard parameters: smoke layer depth; visibility through the smoke layer; and the carbon monoxide concentration and temperature rise in the smoke layer.
