Use of Engineering Methods in Assessment Ventilation of Protected Fire Escape Routes

The design of protected fire escape routes is a process in which a number of technical aspects that are set by Czech technical standards must be considered. The assessment of protected fire escape route's ventilated premises is subject to strict values, which when designed, or when created additionally, often force us to resort to specific measures, like a forced ventilation, enlargement of openings, which leads to expensive construction. This paper focuses on the use of so-called engineering methods to solve this problem, specifically the computational fluid dynamics method, which finds application in the revalidation of otherwise unmet ventilation criteria.
