Bab alhandsah defines evacuation procedures and designs evacuation routes according to building codes and regulations (ex: NFPA, Saudi Arabia standards) but also by means of evacuation modeling software. Modeling evacuation takes into account building characteristics and the number of occupants as well as the layout of the building. Evacuation modeling can be coupled with fire and smoke simulations.
Bab alhandsah uses advanced techniques such as Computational Fluid Dynamics (CFD) to model fire, smoke spread and heat transfer in buildings. These performance-based methods allow the design of innovative and modern complex buildings, such as shopping malls with large open-spaces and covered atriums, which introduce new risk factors concerning fire and smoke spread.
CFD simulations of smoke movements to divide a building into smoke compartments and optimize mechanical or natural ventilation systems is a very efficient and cost-effective method to develop design solutions with respect to fire safety.
Bab alhandsah also prepares exit route drawings and first response information in case of fire or other relevant hazards Fire and smoke modeling in buildings
