DeltaDualCore™ Panel Awning Systems Revision 1-12 27 Figure 4-3. Illustration of DtS base case that will be used for comparison to the proposed system. 4.6 Acceptability Criteria It shall be demonstrated comparatively that the DeltaDualCore™ system (when attached to a Class 1 building within 900 mm of the site boundary) does not increase the risk of fire spread between Class 1 to Class 9 buildings when compared to the DtS base case. 4.7 Design Fires Three fire scenarios are to be considered; one within the Class 1 building, one within or below the Class 10a structure and one on the neighbouring allotment. The three design fires are described in Sections 4.7.1.1 to 4.7.1.3 below. 4.7.1.1 Design Fire 1: Fire Within or Below the Class 10a Structure In the case of a Class 10a structure intended to be used for a patio or awning application, fire load is likely to be limited as it would not be fully protected from the weather. However, the patio or awning is able to house a wide range of fire loads which may include a combination combustible goods such as external furnishings, storage of household goods, a laundry rack, gardening supplies and the like. To quantify a worst credible design fire the following fire loads are considered: • Upholstered Sofas – 500 kW to 2900 kW as shown in Figure 4-4.
