that is essential to preserve for the "sustainability" of intervention. Thinking solar
integration on roofs (given the lesser desirability of vertical enclosures for the typical
character of high density of buildings, except any margin houses or houses-mura ...) it is
clear how the roof material (slabs, tiles, …) is one of the architectural key-values of the
centers concerned, whose morphology marked by valleys, hills and mountains often
makes them an integral part of the landscape.
The "fifth façade" of the buildings, the roof, is therefore an important element that we
must preserve and enhance with a rigorous analysis of compatibility. In the many cases
where the presence of solar systems does not prejudice the monumental historic value
of the settlement, as in most towns in Abruzzo that will require in the next years a
substantial rebuilding, we must promote interventions that, both from an architectural
point of view that technology, has to be carefully deepened and care at the context . The
basic policies for building scale integration, reaffirmed the need for control of landscape
size of intervention, are divided between those linguistic-expressive type and those of
constructive and technological-performance (Bonomo 2012).

The
morphological-figurative integration
, in general, can be read in the PV system
capacity to contribute to expressing the linguistic forms and rules that govern the
structure and composition of the architectural language. Basic aspects of architectural
language can be analyzed:
- At the scale of the building organism;
- At the scale of the constructive component.
Integration into the building envelope of photovoltaic systems also implies the need to
consider these components in their dual function of constructive/architectural and energy
production elements. The acknowledgement of
constructive-technological
integrability
can be linked to the analysis of some main requirements:
