Within complex public buildings with high numbers of visitors, people should be able to rely on a safe evacuation in case of an emergency. In the Netherlands, often a complicated calculation based on the Dutch Building Code is made during the design phase of a fire safe building to indicate the total evacuation time and to obtain a building permit. This static calculation provides insufficient understanding of the total evacuation and does not grow along with a change of the building during renovation or change of usage.
From numbers to moving images
By implementing innovative state of the art 3D simulation software as part of Fire Safety Engineering visitor numbers in the calculations will be transformed into moving images. With a simulation the evacuation time can be calculated based on occurring crowds, routes and walking times from origin to destination. At the same time understanding about bottlenecks and obstructions during an evacuation can be visually obtained. Modelling, simulating, analyzing and visualizing contribute to an understandable evacuation process and a safer building.
A 3D simulation is ideally suited to share knowledge about the building evacuation with different stakeholders. Therefore the right measures to obtain logical escape routes can be taken on time, based on different scenarios and to reach an optimal throughput of people. As a benefit unnecessary areas in escape routes can be saved which can result in more functional space. Besides, the consequences of a renovation or design change can be assessed quickly. This can help convincing stakeholders to take a decision and save valuable time and money. A simulation provides insights even before the building has been built and the evacuation exercises have been performed.
By using 3D evacuation simulations people can rely on a safe evacuation in complex public buildings with a high number of visitors.
