Model 3: Sensitivity Study - Model geometry for a Delta MW and EPS-FR roof assessing impact of awning width on heat transfer to the site boundary.B.3Design 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/m 2is adopted which has been derived from bench-scale fire testing that was conducted by the University of Queensland Revision 1-441'
