Abstract

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 impacts of natural hazard. The idea of resilience in buildings is developing and buildings have to be able to survive and maintain their own functionality and performances even in an uncertain future. Moreover, environmental degradation is accelerated by climate changes and global warming and by the linked disruptive events. As regards, the paper focuses on climate change effects in summer and on how it is possible to reduce them through façade system retrofit in Mediterranean climate. Most of the facades in the existing building stock need retrofit, but current practices do not allow designing systems that adapt to changing external conditions. Moreover, in comparison with other elements of building envelope, such as roofs, facades have an extended surface area that has the greatest influence on comfort at pedestrian level in urban area. Therefore, they are crucial elements to ensure energy efficiency and indoor comfort, but also to mi-tigate urban heat island phenomenon. Starting from energy dynamic simulations of an existing building within an urban area in a Mediterranean city, different retrofitting actions regarding building facades are applied (external insulation, PCM, green wall, cool materials). Then, they are compared in order to understand the influence of different building skin typologies on neighbour-hood microclimate changes and their different resilient behaviour.The aim of the work is to develop a set of climatic resilience indicators for differ-ent building facades (in particular opaque envelopes), in order to take into account resil-ience ability against climate change, both inside and outside of buildings. At the same time, it is introduced a new holistic approach in the evaluation of buildings performanc-es and their interaction with urban neighbourhood climate.
