It is possible to identify two
approaches to the size of
the intervention, one closer
to industrial market reasons
which, over recent years, has
seen the building industry
affected by a real revolution
connected with product
innovations and the other
closer to the sensitivity of
the property market, which is
experiencing a very severe crisis
in terms of both turnover and
profitability. The two different
orientations come together
34 paesaggio urbano 2.2013
to determine the operative
direction of those involved who
can and, in some cases, must
intervene on existing buildings.
The regional law for the
reconstruction of the areas
affected by the earthquake of
20 and 29 May 2012 envisages,
from this point of view, general
improvement objectives for
energy performance at least in
the administrations that decide
to make use of the urban tool
that the law intends to govern:
the “Reconstruction plan”.
Within each plan, alongside
the urban incentives and the
reward measures that aim
to promote the rapid and
complete implementation of
the repairs, restoration with
seismic improvement and
reconstruction, there must, in
fact, be room for important
measures that aim to achieve
higher levels of energy
efficiency. It would therefore
be desirable that, as part of the
“Reconstruction plans” for the
historic centres affected by the
earthquake (Mirandola, Finale
Emilia, Concordia sulla Secchia,
etc.), effective operative tools
should be provided in order
to determine the directions to
follow also concerning energy
improvement interventions.
On the one hand, it will be
necessary to identify the scale
of the intervention, in other
words, the size interval within
which to identify the UMI
(Minimum Intervention Units)
so that it is possible to achieve
the best results in performance
terms. The same size interval will
constitute the unit of evaluation
of the improvement level
attainable and, in final analysis,
validation of the project. On the
other hand, through studying
sufficiently approximate
intervention scenarios, it will be
necessary to provide guidelines
for the intervention that aim to
reach significant performance
goals but without ever
compromising in any way the
cultural and testimonial value of
the historic buildings.
