Abstract

Global warming increases the probability of extreme events and heat waves, intensified by Urban Heat Island phenomenon, triggering severe impacts on both human health and economy. The paper aims at developing a new methodological approach for the assessment of building ability to face rising temperatures, also considering the effects on the surrounding urban areas. It focuses on resilient retrofitting strategies need for building envelope according to three macro-categories: reliability, adaptability and mitigation ability. A set of indicators is defined to achieve a Response Index to cope with heat waves. The method is tested on reference building and its neighborhood. The selected strategies are investigated through an integrated and multilevel analysis with EnergyPlus and ENVI_met, in three different cities with increasing summer temperature. The final comparative analysis is carried out through a multi-criteria analysis according to the identified indicators. The best responsive solutions result the green ones combined with high albedo, but the research highlights also some controversial aspects. The method can be a valid tool to support the decisional process about heat waves mitigation in the roadmap towards a more responsive built environment.
