Making built environment safer in slow and emergency conditions through behavioural assessed/designed resilient solutions: results from the BE S2ECURe Project

Different risk conditions affect the Built Environment (BE), that is a network of buildings, infrastructures, open spaces, and users. They can appear in an unpredictable and quick manner (Sudden-Onset Disas-ters-SUODs, e.g., earthquakes, terroristic attacks), or emerge gradually over time (SLow Onset Disasters-SLODs, e.g., climate-change related, pollution, heat waves). Existing BEs, especially historical ones, are generally characterized by a poor resilience level, as shown by many recent disasters. Increasing the BE solutions means to move towards: (1) mitigation strategies focused not only on the buildings, but also on the neighboring network elements, and, mainly, open spaces; (2) the inclusion of user-centered factors (exposure, vulnerability, behaviors) in risk assessment and reduction; (3) SUODs-SLODs combination, pursuing a multirisk perspective also in case low probability-high impact events coupling; (4) supporting stakeholders’ assessment with “what if” approaches for multirisk simulation-based evaluations, and with quick preliminary assessment approaches also based on BE typological analysis; (5) exploiting users/stakeholders’ training to increase resilience from the bottom. The BE S2ECURe – “(make) Built Environment Safer in Slow and Emergency Conditions through behavioUral assessed/designed Resilient solutions”, supported by MIUR in the context of the Italian PRIN, adopts these standpoints to develop methods, tools, and guidelines for BE resilience assessment, risk-mitigation strategies design, and users’ risk awareness increase, by using multirisk and user-centered criteria. This work offers an overview of the main project results, focusing on risk assessmentand mitigation issues in BE typologies (BETs), since they can represent archetypes of real worldbased scenarios. Thus, the BET modelling and multirisk behavioural-based assessment could be the basic point for supporting designers and stakeholders to tailor risk mitigation strategies (i.e. architectural interventions, safety management, training via Virtual and Augmented Reality techniques) depending on the case studies specificities.
