“…In order to meet the objective of adequate fire protection, public buildings are equipped with passive and active fire protection systems [1][2][3]. One of the applications that are currently being implemented is the use of smoke vents, which are designed to remove smoke and heat during a fire [4,5]. They are an extremely important element of any smoke exhaust system.…”

The aim this paper is to present the simulation of the building in the computer program PyroSim by Thunderhead Engineering based on the FDS calculation engine. The article presents simulations of the use of smoke vents and their impact on fire safety in a public building based on the Fire Dynamics Simulator (FDS) calculation engine. Two scenarios were analysed in the simulation. The first simulation shows 180 seconds of fire without the smoke vent, while the second simulation shows 150 seconds of fire with the smoke vent open. A fire power density of 500 kW/m2 was adopted and is used in each case as well as the fire development coefficient, which was calculated on the basis of literature data. On their basis, simulations were carried out, the results of which were used to draw conclusions.
