Energy Resilience of Historical Urban Districts: A State of Art Review Towards a New Approach

The paper points out the opportunity to address the current need for energy retrofitting of the historical built heritage according to a long-term perspective. For this purpose, it focuses on the concept of resilience, through a state-of-the-art review of ongoing studies and researches. Particularly, it pays attention toward the historical urban districts as integrated systems, where economic, social and cultural values should be protected in order to persist during the time. Thus, it recommends “sustainable” strategies that, beyond the thermal improvement, should achieve a resilient vision linked with the dynamic capability to adapt to climate changes by energy self-sufficiency.
