“…In order to study the stack effect in high-rise buildings, several studies were consulted in which different software were used, FireSTORM [29], COSMO and CONTAM [30] and PyroSim [31], [32], following the main advantages and disadvantages of each. Moreover, in order to understand the stack effect phenomenon, experimental studies started in this regard were also consulted [30], [33]- [36] concluding that a faithful experimental representation of the stack effect cannot be reproduced by a small-scale experiment. If we refer to tall and very tall buildings, the stack effect is much more present due to the considerable height of vertical gaps, stairwells and elevator shafts.…”
