The eco-sustainable recovery as a model of intervention on the historical centres
The project of transformation of historic environments, today re-open the relationship
with those "rules" of "sustainability of the ancient building often consolidated in its
intimate nature of construction and development. Overcome ideological positions, the
intervention of recovery needs to fix, how to address line, an operating aimed to the
search of "compatibility". Recognized as intervention approach the "controlled
improvement" instead of an undifferentiated performance retrofit, the design process
consists of a gradual deepening of knowledge, that starts from the critical reading of
typological structures and of various constructive, material, spatial, environmental and
functional correlation in the analyzed context. The definition of the aggregation rules of
the built tissue, with analysis of transformation and evolution of syntactic, typological and
constructive systems, allows to identify the scale of values or to define the
degree of
transformability
of the existing (i.e. the vocation to be transformed) and outline, following
comparative assessments between values and needs, the forms of compatible
intervention (Zordan et al. 2008).
Sustainable recovery
, in particular, aims of curing,
within the recovery process, the specific requirements of eco-compatibility of intervention,
such as the
safeguard of the eco-system
(air, water, soil, ...),
the rational use of the
climatic, energetic, water and
material
resources
besides comfort and wellbeing of users.
The basic heritage of Abruzzo, consisting of a network of small medieval settlements of
high historical, landscape and environmental value, after the recent earthquake disaster,
requires a deep rethinking of models and strategic schemes of intervention (De
Berardinis 2008). In these places, the use of bio-climatic and ecological criteria, as well
as integration of systems for using renewable energy, requires a thorough process to
verify the
integrability
, variable case-by-case and to articulate at different scales: from
individual building components to the urban dimension of the village (streets, rue, open
spaces, valleys, etc.).
