Urban settlements are subject to multiple risks associated with meteorological hazards and to the effects of climate change that require strategies for hazard prediction and prevention, adaptation to impacts, vulnerability reduction and planning of mitigation measures. The implementation of climate-proof strategies, defined as actions able to prefigure and prevent critical events, requires the assessment of climate risks and the interpretation of the urban system as a complex system to manage the continuous morphological, functional, and behavioural-performance interactions between its systems and subsystems (Losasso, 2018).
To analyse the urban system holistically, it is necessary to consider multiple information. The support of enabling technologies allows the implementation of innovative knowledge and design methods. At the same time, risk assessment is performed by climate models that support decision-makers through qualitative assessments of climate effects on the urban environment. Within the framework of decision-making support modelling for climate proof design, there are knowledge gaps in terms of climate-related damages, benefits, and costs of design measures, as well as gaps in simulations concerning the local characteristics of the built environment (EC, 2021; Mercogliano et al., 2016). Thus, the necessity emerges to integrate knowledge frameworks and impact assessments in relation to local contexts through downscaling processes, as well as the need to relate risk and impact models with metadesign strategies and solutions.In the scenario of the green and digital transition, the progress of cities is, therefore, closely linked to the use of technologies. Smart Cities are characterised by their “smart” ability to respond to different environmental, social, and economic issues by implementing both “soft” measures to manage, control and monitor the urban environment, and “hard” measures, such as services and infrastructure, aiming at achieving systemic balance between socio-cultural, environmental, technological and economic aspects (An-tonini et al., 2018; Ullah et al., 2021). It is in this context that the research proposes the Coast-RiskBySea model (COASTal zones RISK assessment for Built environment bY extreme SEA level) for the knowledge of coastal flood risk oriented to the decision-making support of the climate proof project. The research presented was carried out as part of an innovative PhD pro-gramme with an industrial approach, which, in line with the objectives of the European Community, was aimed at defining new synergies between environmental design and enabling technologies. The paper focuses on the test of the Coast-RiskBySea model in the design-making support phase. Previous work investigates workflow, applicability, and accuracy of simulations (Clemente et al., 2022), as well as transferability (Clemente, 2022).
