Abstract
Abstract. The high exposure of future changes in temperature trends in the southern part of Mediterranean area encouraged scientific community in defining strategies aiming at the reduction of cooling needs as short and long-term goals. Furthermore, local urban properties and their transformation contribute in altering microclimate at the micro-scale. Focus on a specific part of urban built stock, historic districts represent an exception in managing processes of recovery and energy retrofit strategies due to their landscape values; moreover, these districts show their recent transformations caused by the previous abandonment phase and, often, consequent loss of blocks. In that context, the paper shows the representative case study of historic district of Molfetta, in Apulia region (Italy): here, the energy assessment takes into account the effect of the abandonment of the district during 60s on the in use residential built stock in a temporal-climate prediction. As it was well demonstrated in previous experiences, strategies for the energy retrofit of residential buildings in historic district should allow to identify their inherent bioclimatic behaviours according with the genius loci evidences; furthermore, recognize and correct previous failures represent the opportunity to “learn from the past” in the “resilient thinking” process, above all after traumatic events.
Highlights
The assessment and the characterization of the effects of climate change represent the main focus of scientific research and political debate all over the world (Bhandari, 2015; Gotham, Faust, 2020; Grafakos et al, 2020; Steynor et al, 2020; Yun et al, 2020)
It is true that the landscape value for buildings arranged in historic districts cannot forget the relations between single buildings, as well the historic processes of transformations and abandonment of some parts that represent an open discussion for their management at district scale until now
The presented paper aimed to define a proper system of instruments and processes useful for the assessment of energy impacts on actual occupied dwellings derived from the presence of uninhabited ones and/or in low state of conservation, as well as derived from previous critical events
Summary
The assessment and the characterization of the effects of climate change represent the main focus of scientific research and political debate all over the world (Bhandari, 2015; Gotham, Faust, 2020; Grafakos et al, 2020; Steynor et al, 2020; Yun et al, 2020). Focusing on cultural heritage retrofit and on resilient design strategies (Correia et al, 2014; Tyler, Moench, 2012), knowledge and capacity to learn are assonant criteria It is well accepted by the scientists and cultural community that traditional buildings are the result of a slow process of onsite experimenting of techniques and codes of good practices towards the satisfaction of human needs, health, well-being and security (Guillaud, 2014). The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLIV-M-1-2020, 2020 HERITAGE2020 (3DPast | RISK-Terra) International Conference, 9–12 September 2020, Valencia, Spain techniques and good practices derived socio-cultural, socioeconomic and environmental values of built heritage These buildings represent the result of several transformation actions not strictly related to the genius loci experience. The present work highlights the relevance of knowledge as the first part of methodological framework, focusing on the abandonment phenomenon that represents, until now, a peculiar characteristic of some Italian historic districts
