b'Delta MW and EPS-FR Panel Awning and Patio Roof System Appendix B FDS Assessment B.1Introduction An FDS analysis is undertaken to assess the combined heat transfer to the site boundary for the Delta MW and EPS-FR roof system when compared to the DtS base case. B.2Model Geometry The model geometries for each of the three FDS models use are described in Figure 5-3, Figure 5-4 and Figure 5-5 and include: 1.Model 1: DtS base case. 2.Model 2: Delta MW and EPS-FR roof system with equivalent dimensions to Model 1 (performance solution case). 3.Model 3: Sensitivity case where the width of the awning in Model 2 is increased by 100%.Site boundary A Upper surface of roof is Ba burner with constant HRRPUA of 332 kW/m 210MW Peak HRR fire 4 m4 m 6 m 2.95 m 2.7 m C D6 m 5 m FRONT VIEWSIDE VIEWFigure 5-3.
