Heat and smoke removal in semi-open car parks

If a design of a semi-open car park without any mechnically ventilation system doesn’t meet the functional requirements stated in the Dutch building code directly, it is possible to show that the created design has an equal fire safety level as meant by this regulation. However it is questionable if the current guidelines meant to show this equivalence, will ensure a satisfactory amount of ventilation in case of a car park fire, for every situation. In this paper a study is presented in which the fire safety level of semi-open car parks is analyzed by the use of different variants which are assessed on the fire safety level by validated Computational Fluid Dynamics (CFD) simulations.
