PyroNES: PYRo-mOdelliNg and Evacuation Simulation

Structural fires continue to pose a great threat towards human life and property. Due to the complexity and non-deterministic characteristics of a building fire disaster, it is not a straightforward task to assess the effectiveness of fire protection measures embedded in the building design, planned evacuation strategies and potential modes of response for mitigating the fire’s consequences. In addition, currently, there is a lack of means for realistically and accurately recreating the conditions of building fire disasters for purposes of training personnel in order to be sufficiently prepared when vis-a-vis with such an environment. The way that a fire propagates within a building, the diffusion of its volatile products, the behaviour of the occupants and the sustained injuries not only exhibit non-linear behaviours as individual phenomena, but are also entangled in a web of codependencies to each other.

Whereas several systems have been developed and implemented in order to address the need for an accurate and realistic simulation regarding the development of structural fires, the diffusion of volatile gas fire-products and the emergency evacuation, most of the existing applications lack backward causality and hence they are incapable to calculate the interactions among the subsystems involved in a structure fire incident that eventually produce a single emergent phenomenon.  

The objective of PYRONES is to deliver  a comprehensive and realistic simulation of the overall conditions evident in structural fire incidents. The complexity of the behaviour of the fire, its volatile products and of the building population will be integrated into the system along with their respective interactions operating during runtime mode. The level of simulation accuracy will be elevated due to the direct interconnection of the fire and crowd simulation models and also due to the introduction of an intermediate injuries simulation model. 

PYRONES aims to be seamlessly integrated into current engineering workflows by becoming a part of widespread BIM approaches towards building design. Through the use of a plugin for Autodesk Revit that extends its capabilities in terms of expressing necessary attributes for structural fire simulations, engineers will require minimal training to use PYRONES. PYRONES will constitute a state-of-the-art training platform for professionals in the security field and for staff occupying large public buildings.

PYRONES is a 18 months project started in July 2014 and is funded by the Ministry of Education and Religious Affairs General Secretariat for Research and Technology under the Bilateral R&D Cooperation between Greece and Israel 2013‐2015.
