The purpose of this article is to analyze the variation of the tenability criteria (convected heat, radiant heat, toxic gases and smoke visibility) on the main evacuation paths inside of an educational building, in case of fire. The analysis is performed by numerical simulation for three different fire scenarios. The fire load density of fire space (an office type room) is the same, but the main combustible material is changed: wood, plastic and polyurethane foam. The analyzed building can house a great number of people (over 600) and its inner atrium could facilitate the spread of smoke and hot gases in case of a real fire. According to the numerical analysis, it has been concluded that the convected heat variation is not a significant one (within the engineering limits), but the radiant heat, toxic gases and smoke visibility are highly dependent on the type of considered combustible materials.
