Façade retrofitting: from energy efficiency to climate change mitigation

Since climate changes are now evident, it is not only important to achieve high level of energy efficiency, but also to think about retrofit actions in order to mitigate the natural hazard impacts and to make buildings resilient. The paper focuses on climate change effects in summer and investigates how it is possible to reduce them through façade retrofitting solutions (external insulation, PCM, green wall, cool materials) in Mediterranean climate. The goal is to develop a set of climatic resilience indicators for opaque envelopes in order to consider resilience ability against climate change, both inside and outside of buildings.
