In the current scenario where urban areas are exposed to extreme climate phenomena, resilience of cities and buildings becomes fundamental.
Thus, not only defensive, traditional actions, but also alternative solutions towards resilience need to be implemented. Amphibious and floating houses, still not investigated in literature, allow the building to adapt to water presence due to their specific construction and technical properties.

Nowadays, passive strategies are identified among the preferred solutions to reduce energy consumption and to increase comfort in the built environment. Indeed, such strategies allow energy saving by exploiting the intrinsic characteristics of materials. In this work, an innovative cool, photoluminescent paint is considered for application in the built environment, as a passive strategy to (i) reduce energy for cooling in the hot season, (ii) maintain lower surface and air temperatures, thus benefiting comfort and (iii) contribute to the lighting of the outdoor public space.

Negli attuali scenari di crescita delle aree urbane e del consumo di suolo e di inasprimento di fenomeni climatici estremi, la resilienza delle città e degli edifici assume un ruolo di primo piano. Tra i fenomeni più critici vi sono l’innalzamento del livello del mare e la maggiore frequenza e intensità dei fenomeni piovosi estremi, con la crescita del rischio di inondazione. È necessario, pertanto, implementare azioni difensive tradizionali ma anche soluzioni edilizie e tipologiche alternative per la resilienza.
