UEE-GoZone

GoZone is a numerical model that solves mass balance and energy balance equations to compute the evolution of the temperatures in a fire compartment.

	Classical zone model	GoZone
Shape of the compartment	Only the floor area (in m²) and the perimeter (in m) are considered.	The real shape of the compartment is considered.
Position of the openings	Real position along the perimeter is not considered.	The precise position along the perimeter is considered (important in case of air control situation).
Distribution of the full load	Uniform on a certain area.	Can vary from place to place on the floor
Fire propagation	Predetermined by the RHR curve.	Computed by the code as a function of a critical ignition energy of the fuel load(s).
Air control	On/off in the whole compartment.	Affects only some zones of the floor area.
Main outcome	Hot zone temperature and height of the clear zone.	Idem + radiant flows across the whole compartment.
Interface with F.E. structural codes	Has to be made via time temperature curves.	Automatic to SAFIR.
