The safety of people inside a building during a calamity that requires evacuation depends on the organisation and available evacuation routes. With codes and standards it is possible to design standard buildings up to the required level of safety. For more complex buildings or specific groups it is of added value to evaluate the strategy and scenario’s with computer simulations. As for all type of simulations it is a perfect tool to compare scenario’s and measures since boundary conditions can independently be varied and fixed.

Evacuation large entertainment centre

This short movie shows the evacuation process of a large entertainment centre. The simulation considers 6.364 persons divided over 4 building floors. In this movie the ground floor is shown. The model includes stairs, doors and stands. With use of simulations the effectiveness of the evacuation protocol has been analysed for a large group of visitors.

This type of simulation provides the required time for evacuation. It takes into consideration the building geometry and the queueing at exits. A simulation does not always calculate shorter times compared to hand calculations according to codes, but is always more accurate and produces very understandable results. In the simulation the efficiency of the location of the exit is taken into consideration constraining the flow of evacuees towards the exit.

Biennale di Venezia – Elements of Architecture

As contributor of the Biennale di Venezia we provided evacuation and circulation simulation results which were shown in the Corridor Room at the 14th International Architecture Exhibition. Subject buildings and scenarios are chosen in consultation with OMA. All 5 movies are available at our YouTube channel. One example is shown on the right.


Evacuation study Stad Amsterdam

The Stad Amsterdam is a passenger sailing vessel offering corporate events, adventurous sailing cruises and luxurious cruises towards many different destinations.

The objective of the evacuation simulations was to calculate the evacuation time of the current proposed evacuation route arrangement from the Longroom to the assembly station and compare the obtained time with a fictive arrangement using SOLAS compliant stairs and doors. The current evacuation route arrangement is considered to be acceptable in case that the obtained Required Safe Evacuation Time (RSET) of the current arrangement is shorter than the RSET of the fictive SOLAS compliant arrangement.

The study and result have been approved by the USCG (United States Coast Guard).
