compared to the 15 years considered to be satisfactory in the building sector to
consider the implemented measure economically profitable.
The incentive tool, moreover, allows to clear out the political orientation and
the territorial development direction that a given local context want to pursue,
producing as side effect the economic development in the area and costs reduction,
due to the widespread of the supporting technologies.
From the analysis of the Italian Report ONRE

2013 (Cresme Ricerche s.p.a e

) related to energy innovations in buildings, comes into light an
interesting definition of those that are considered the current incentive measures
used in the building sector within the building regulations. The prizes or incentives
can be classified into three main categories.
The first is related to economic incentives, as reduction of the secondary
urbanization burdens

or elimination of the building contribution, most often
increasingly recalibrated depending on the level of attainable energy saving, of
eco-compatibility of materials and of the adopted constructive technologies, as
well as of the buildings features surpassing the mandatory limits set by the reg-
ulatory framework.
All these are used as incentive measure in 45 % of the new municipal building
codes.
The second category concerns incentives such as urban planning, volumetric
prizes, for which recognizing the improvements in the energy performance of
the building is granted an extension that will not be calculated as floor area. The
deduction from the whole volume, of the increased volume required by the
installation of new plants or the creation of thermal coating or of other energy
efficiency measures, in derogation from the existing general urban plan is also a
very common measure in the new municipal building codes in Italy.
The third class of incentives is the direct financing through calls for some given
measures; it is the case of calls for direct contributions.
Some municipalities, such as Bari in southern Italy, has set incentives for those
implementing sustainability measures in building such as the reduction of the
waste taxes.
It is also necessary to recall, in this context, the current national situation
concerning building restructuring and energy efficiency measures.
The public incentives framework is up to now very favourable, symptom that
these measures are considered relevant within the national energy policies and
kick-starting economy measures in Italy.
Just as an example, the taxation reduction on building restoration (36 % of
invested capital), on energy efficient restoration of buildings (65 % of invested
capital) and the Conto termico (supporting small measures on existing buildings,
to increase energy efficiency and the production of thermal energy from renewable
energy sources).
