Heat waves response strategies through technological approach for adaptation and mitigation in urban areas

The paper analyses the importance of a design that considers the issue of increasingly recurring and impactful heat waves under a climate change regime with predictably higher occurrence of extreme events. Cities show higher temperatures than surrounding areas and these prospects amplify negative effects on infrastructure, human health, the environment and the economy. Of extreme interest are the logics followed by the most virtuous cities that deal with the problem and, in relation to their own context, try to defend themselves by organizing mitigation and adaptation strategies, able to tackle the situation and improving their resilience. The research analyses and reviews data and information on heat waves and implements a decision-making framework for bioclimatic retrofit. Technological strategies to mitigate heat waves are outlined, focusing on green, blue and grey solutions with the help of state-of-the-art instrumentation and advanced technologies to increase the capacity to respond to excess heat also in perspective. Mitigation strategies consider the multifactorial aspects of the phenomenon and the scales of analysis and response with which the project must challenge itself.
