The fire safety norms do not involve an approach integrated with other instruments or building model BIM , but provide a list of information and constraints. These codes are now shifting away from a prescriptive-based towards a performance-based method due to recent progress in fire safety engineering.
Following this approach, a case study simulation of a multi-purpose centre was carried out in Tivoli, near Rome.
This simulation allowed greater freedom in architectural composition, a lower risk to people, a larger number of material and building components used and higher safety standards to be achieved. The model is based on the FDS Fire Dynamics Simulator language, a simulation code for low-speed flows, focused on smoke, particle and heat transport by fire.

Another important motivation was the that might compromise the identity of the project. The combustion process is a sequence of chemical In many cases, this design logic led to the vari- reactions between a fuel and an oxidant, accom- ous conference halls being situated as low as pos- panied by the production of heat, smoke and the sible and for fire fighting purposes to use water conversion of chemical materials.

Heat Release Rate Parameter Codes do not involve an integrated approach nor do The Heat Release Rate - HRR - is the main parameter advanced CAD tools like building information mod- governing the fire phenomenon; it influences many elling - BIM, but they do provide a list of documenta- other fire characteristics.
Literally, the HRR indicates tions and prescriptions to be fulfilled, which are use- the heat released by the combustion of a material ful in the early design phases Balaban et al.
Curve peak values change according to the ma- terial being burnt. For example, plastic rubbish has a peak of 80 KW, while a car can reach KW. As the HRR increases, also the temperature and the rate of temperature rise increase, thus acceler- ating fire development.
In addition, increased HRR the density of the -ith material component of the results in reduced oxygen concentration and in- layer at temperature Ts, divided by the initial density creased production of gaseous and particulate mat- of the layer.
