Model 3: Sensitivity Study - Model geometry for a DeltaDualCore 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 core sandwich panel roof system and Design Fire 1 in accordance with Section 4.7.1.1. For the EPS 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 and is Revision 1-1144'
