B.3 Design Fire 
The design fire is taken as the combined fire load of an EPS-FR core sandwich panel roof system and 
Design Fire 1 in accordance with Section 4.7.1.1. 
For the EPS-FR core roof system, a heat release rate per unit area (HRRPUA) of 332 kW/m2 is adopted 
which has been derived from bench-scale fire testing that was conducted by the University of Queensland
