B-RISK: Design fire tool


B-RISK allows fire simulation results to be presented in a probabilistic form and allows the variability and uncertainty associated with the predictions of the fire environment to be quantified.

B-RISK allows several features to be integrated within the design tool to simulate building fires such as:

  • a design fire generator and item-to-item fire spread module allowing building contents to be randomly placed within a room and the overall rate of heat release to be determined
  • a comprehensive sprinkler response module including operation of multiple heads and parameters for effectiveness and reliability of sprinkler systems
  • reliability of other systems such as smoke detectors, mechanical systems and passive elements such as doors
  • C/VM2 user mode - useful for fire analysis required to be in compliance with the New Zealand Building Code
  • visualisation of geometry and results using Smokeview software
  • the inclusion of balcony spill plume relationships to facilitate the design of smoke management systems within buildings.

BRANZ and the University of Canterbury worked together to develop B-RISK, which replaced the BRANZFIRE program.
