Starting with the VAT and SAT tools, we provide summarized information on how these tools where developed and initially implemented and verified (WP6) and we present the VAT and SAT tools final format and their testing in real WUI properties including the VAT adaptation to Scandinavian WUI. Following, we compile the demonstration of the performance-based design (PBD) methodology through 4 different case studies: being the first two WUI properties in Madrid (Spain), the third one a community shelter located in Central Portugal and the last one a WUI property in Sweden. Concluding remarks are finally stated, detailing the upscaling challenges of WUIVIEW outcomes.

About this deliverable WUIVIEW stands for Wildland-Urban Interface Virtual Essays Workbench, and it is a project funded by the Directorate General for European Civil Protection and Humanitarian Aid Operations (DG ECHO) and coordinated by the Universitat Politècnica de Catalunya (Spain). WUIVIEW final aim has been to reinforce WUI fires risk reduction strategies by developing innovative risk management tools to help WUI communities adapting to extreme wildfire events. The project has been conceived and performed through a clear product-oriented approach, so that to come up with tools within technology readiness levels (TRL) values around 4-5 (i.e. with developments performed in experimental/demonstration pilots) ready to be tested in real environments in subsequent follow-up. WUIVIEW products consist on: i) basic, easy-to- use tools for vulnerability and sheltering capacity self-assessment (D6.1) and ii) in-depth analysis tool of fire impact in properties based on fire safety engineering methods (performance-based design guideline, D7.1). This deliverable gathers all the information concerning the pilots that have allowed WUIVIEW products to be tested in relevant environments. In one hand, the deliverable reports development and demonstration efforts devoted to test the VAT (Vulnerability Assessment Tools, Mediterranean and Scandinavian versions) and SAT (Sheltering Assessment Tool) check- lists, starting with a preliminary campaign for tools’ fine-tuning in which 18 WUI properties (12 in Portugal, 5 in Spain and 1 in Italy) have been involved, and continuing with the final testing where a total of 6 WUI properties have been checked: 3 for the Mediterranean VAT and SAT, and 3 more for the Scandinavian VAT. Following, the PBD guideline developed to perform a detailed vulnerability assessment in WUI properties has been showcased in four different properties entailing different PBD objectives and fire scenarios. These properties are: two dwellings in the Madrid region, with different characteristics in terms of building systems and residential fuels configuration; one community shelter located in Leiria District in Portugal, analysed thanks to the joint effort between the Portuguese National Project “Aldeias Resilientes/Abrigo Coletivo” and the Fire Brigade of Savona/WUIFI-21 project, and one Swedish WUI property reflecting typical building practices and landscape in Scandinavia. Case studies have shown the readiness of the WUIVIEW tools to be demonstrated in operational environments. To this end, this deliverable also gathers final remarks highlighting challenges that further development and deployment activities may encounter. 5 WUIVIEW – GA #826544 D.7.2 Report on case studies 2. Demonstration of SAT and VAT tools 2.1. Summary of development In past WUIVIEW work package 6, structure survivability and sheltering capacity at the WUI microscale was analysed in detail through literature survey of WUI standards and research articles and through simulation by means of CFD tools (FDS and ANSYS-FLUENT). Results from these analyses were distilled and translated into two simple (checklist type) self-assessment tools of structure vulnerability and sheltering capacity, available in their primary format in Deliverable 6.1. The tools have experienced a complete cycle of implementation, testing and refining (detailed in following section 1.2) that has allowed the development of final versions to be showcased in relevant environments. Final VAT and SAT tools have been defined and implemented through user-friendly interfaces (section 2.3) to be tested in Mediterranean dwellings (section 2.4), and further adapted for Scandinavian WUI communities (2.5). It has to be highlighted that Northern WUI has significant differences from Mediterranean WUI regarding landscape and wildfire behaviour, building practices and residential fuels and also community behaviour, risk perception and preparedness. To provide context on these issues, section 2.5.1 gathers background information on Scandinavian fire incidence and regimes, regulations and building practices. 2.2. Initial implementation, testing and refinement The methodology for quick self-assessment of structures survivability and sheltering capacity presented in Deliverable 6.1 was initially implemented using the ArcGis Survey123 tool (Esri, 2020) in Portuguese language (Figure 1a). By using this tool, data collected were immediately available in the ArcGIS platform (Figure 1b). The resulting survey is available here: https://survey123.arcgis.com/share/9db266bd708e45d99e5bbc86bde70fdb a) b) Figure 1.

According to the results obtained and the feedback given by those handling the survey, the design of the tools was improved. Figure 2. General view of the location of the structures tested in summer 2020 to check the first version of the Vulnerability Assessment Tool (VAT) and the Sheltering Assessment Tool (SAT). Points detected for improvement were the following ones: 1. Several questions were not specific enough. 2. Respondents could see questions that did not apply to them. 3. An automatic value
