In revising BRI2 to construct BRI2002, consideration was made on the improvement of the physics, numerics and convenience of use. As to 1) Physics sub-models: a) Generation of chemical species, b) Convective heat transfer and c) Smoke extraction efficiency, 2) Numerics: a) Convergence criterion and b) Heat release rate around equivalence ratio equals one and 3) Improvements for convenience in practical application: a) Change of opening, b) Horizontal opening and c) Simple output files. Sample predictions using BRI2002 were also conducted.
