b'DeltaDualCore Panel Awning Systems detailed within the UQ Cladding Materials Library. Figure 5-6 indicates the measured HRRPUA of EPS when exposed to varying levels of heat flux. Conservatively, a constant HRRPUA of 332 kW/m 2is used for the entire roof system (simulating the full upper surface of the roof burning at this peak HRRPUA continuously) as superimposed over Figure 5-6.Constant HRRPUA UsedFigure 5-6. Heat release rate per unit area over time for EPS when tested with 35, 50, 60 and 80 kW/m 2(from the UQ Cladding Materials Library).B.4Results & Conclusion Results are shown in Figure 5-7, Figure 5-8 and Figure 5-9 which indicate the maximum adiabatic surface temperature (AST) and incident heat flux (IHF) on the site boundary when the fire is at steady state for each of the three models. The results indicate that a much larger IHF and AST is reached on the site boundary for DtS base case when compared to the DeltaDualCore system with equivalent dimensions, or the sensitivity case in which the width of the awning is increased by 100%. The sensitivity case indicates that increasing the width of the awning also increase the AST and IHF. With a 100% increase in width, AST increased by approximately 30% and IHF increased by approximately 100%. This indicates that the increase in widths has a greater impact on radiative heat transfer than it has on convective heat transfer to the boundary. This is largely attributable to the larger combustible roof. Convective heat emanating from the combustible roof fire can rise to the sky without affecting the site boundary. However, as would be expected the radiative component increases proportionally with an increase the overall fire size. That said, both the equivalent case and sensitivity case resulted in AST and IHF far lower than the DtS case. As such, the combined heat transfer to the site boundary for the DeltaDualCore system is at least equivalent to or better than DtS base case.Revision 1-1145'
