Fire Calculations, With the Working Left In
An open collection of fire-engineering calculators for fire duration, fire load, thermal radiation, and geometric view factors.
Field notes
The homepage lists two specialist workflows. One estimates equivalent standard-fire exposure duration using NEN-EN 1991-1-2+C1 Annex F and includes bounds associated with NEN 6079+C1 compartments; the other calculates a four-quadrant view factor for a rectangular radiating surface and radiant heat flux at a target point. The site says each calculation page exposes intermediate values, formulas, assumptions, references, and PDF export, while placing responsibility for checking inputs and results with the user.
