involves over their specific discipline: they have induced, in fact, the need for a real
ethical-cultural change towards a abandonment of indiscriminate pulse of possession
and control of nature by technology and a return to the values of a general welfare.
The notion of sustainability, given the more common sense on the balance between
indicators belonging to the aspects of environmental compatibility, ie the energy
efficiency or environmental strategies, tends to the provision of tools and technicalities.
They must consider and rule articulated matrix within which to measure and compare the
possible parameterizations on implications induced by the interventions.
May intervention be considered "sustainable" only because the balance of indicators is
satisfactory and is within the the matrix boundaries?
The answer may be yes only if you are sure you have entered a value that across all
actions in this decision and control, it affects every strategy: ethical awareness.
The concept of sustainability, therefore, moves from the culture of evaluation to the
culture of awareness.
The contributions that follow tend, on the one hand to highlight the importance of
programs in housing policy, implemented through accompanying local and/or
Community measures, with a legislative and project/experimental feature, the other to
explore, through design thinking, the ability to implement strategies consistent with a
conscious and responsible approach.
2. Improving the energy efficiency of buildings in the recovery interventions of the
existing building of social housing.
Gianmichele Panarelli
The global economic crisis has accentuated the phenomenon of the Energy Poverty (in
particular the Domestic Energy Poverty)
(1)
, by imposing important reflections on the
theme of energy efficiency in social building stock which, according to a recurring slogan,
is "the best alternative source of energy."
The condition of the European Social Housig whole presents profound differences due to
different policies, and different meanings of social housing, with numbers ranging from
30% of the housing stock of the Netherlands and 4% in Italy; in any case, the residential
building sector is an important field, as it is expected that this sector provides a
contribution of 40% CO2 emissions until 2020
(2)
.
In fact, more than 120 million Europeans living in 35 million social housing. This heritage
is equivalent to about 18% of the EU total final energy consumption.
The improvement of social housing energy performance is therefore vital for energy
saving, that's why there are different initiatives both normative and prescriptive than
experimental researches.
In 2011 the European Commission in response to Council's request to strengthen
measures to save energy, has developed a new Plan for Energy Efficiency as
communication of 8 March 2011. The Plan aims to combine the implementation of
existing measures with the implementation of new measures, with the aim of achieving
savings for each family $ 1000 to year, improving industrial competitiveness, create up to
2 million jobs and reduce greenhouse gas emissions of 740 million tons.
Because most of the savings potential lies in building, the Plan focuses on functional
tools to upgrading public and private buildings. Individual countries have ratified later the
National Plans.
Most European countries have experienced innovations in social housing law and in
professional practices of social housing operators (SHO). However, remain obstacles to
an efficient energy administration in this sector. Some projects have addressed the
above mentioned issues. Among the most significant, though not exhaustive, it is
interesting the project TACKOBST (Tackling obstacles to Energy efficiency in social
housing) developed under the IEE program (Intelligent Energy Europe), which had the
objective of providing practical tools and methodologies for the associations of social
