Design methodologies for smoke

smoke,morgan,exhaust,design,ventilation,atrium,atria,heat,axis metric,steady state fire ,unsteady state fire,fire,This book summaries the advice available from the Fire Research Station of BRE to designers of Smoke and Heat Exhaust Ventilation Systems (SHEVS) for atria and other buildings. It provides practical guidance on the design of smoke-control systems. It reflects current knowledge and is based on published and unpublished research. It also draws on the authors experience of design features required for regulatory purposes in many individual smoke-control applications.
 The purpose of this book therefore is to provide practical guidance on the design of smoke control systems. It reflects current knowledge and is based on the results of research where available, including as yet unpublished results of experiments. 1n addition, it draws on the authors' cumulative experience of design features required for regulatory purposes in many individual smoke-control applications. Many of these design features have evolved over several years by consensus between regulatory authorities, developers and fire scientists, rather than by specific research,
