Central Registry Toolbox Code Version(s): V7.1.1
Code Owner/Developer: National Institute of Standards and Technology (NIST).


Description: The Consolidated Model of Fire and Smoke Transport (CFAST) is a computer program that fire investigators, safety officials, engineers, architects and builders can use to simulate the impact of past or potential fires and smoke in a specific building environment. CFAST is a two-zone fire model used to predict the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-specified fire.

In May 2004, the Department of Energy ( DOE) performed an evaluation of CFAST against DOE's safety software quality assurance criteria. A gap analysis report was generated that identifies the strengths and weaknesses based upon ASME NQA-1 criteria. Upon completion of this evaluation, CFAST V3.1.7 and V5.1.1 were listed in DOE's safety software Central Registry as a safety analysis toolbox codes.

In February 2017, DOE completed an evaluation of CFAST V7.1.1 against DOE's safety software quality assurance criteria and this version is listed as a toolbox code in the safety software Central Registry. The evaluation report is posted on the Safety Software Communication Forum (SSCF) at https://sscf.energy.gov. This is a password protected website for use by DOE and its contractors and must be accessed using your PIV card to register and then obtain access.
