A new light for
the City of L'Aquila
April 6th, 2009. It was 3.32 a.m. when one of the
most devastating seismic events that have
affected our country in its most recent history struck
the City of L’Aquila and the surrounding towns and
villages, mercilessly razing houses, monuments,
historic buildings, and universities to the ground.
The outcome was like a war bulletin: hundreds of
dead, thousands were wounded and displaced, a
historical and artistic heritage that was one of the
most prestigious in all of Italy, disfigured forever.
More than eleven years after the tragedy, after a long
and complex phase of reconstruction, L’Aquila is
gradually regaining its identity. However, as it can be
expected, in many of the neighbourhoods reborn
from the rubble, that extra quid that can really give
the perception of a city that, in spite of the past, is
ready to re-project itself towards the future, has been
missing for a long time.
Ever since it took over the management of
public lighting the goal of creating a smarter,
safer, and more sustainable city that recognizes
and enhances its urban tradition has been the
common denominator of Citelum’s work in
L’Aquila. The redesign of the facilities subsequent
to the new urban layout and the replacement
of the existing mercury vapor lighting with the
latest generation of luminaires have obviously
not fully grasped the scope and significance of
the lighting and energy requalification project in
the capital of Abruzzo. From the very beginning,
the project itself was indeed conceived and
developed with a much broader perspective: that
of enhancing and giving back through light, to
the population who came back to inhabit the city,
the vital points of access and social aggregation
of the city itself. A design spirit that has first of
all inspired the renewal of the lighting of some of
the city’s most representative architectural sites,
such as the square of the Luminous Fountain:
the intervention involved the replacement of the
pre-existing artistic lighting with a three-level
designed system that, through the use of 73 RGB
immersion projectors and a control panel for
the declination of different lighting scenarios,
ensures the correct lighting of the monument
from different angles. The spirit of L’Aquila’s
public lighting project, however, has found its
most complete expression in the energy efficiency
measures carried out on the installations in the
city areas of Piazza Palazzo and Piazza IX Martiri.
These interventions, aimed at the luminous
enhancement of the revitalized areas, included,
in addition to a careful restoration of the existing
elements of street furniture that had been severely
damaged by the earthquake, the development
of an innovative artificial light dimming system,
called by Citelum Light4Life. Through the
modulation of colour temperature and luminous
flux intensity in accordance with the natural
sleep-wake cycle (from colder tones closer to
sunlight during the first hours of operation of
the system, to warm, less intense colours in the
middle of the night), this system creates the
conditions for perfect synchronization between
the urban environment and the vital rhythms of
people and animals. Light4Life is the first system
of its kind ever made in Italy, whose application
has been made possible thanks to the use of the
most advanced LED technology, the “Kruithof
white LED engine” technology, made available
by NERI. The system is able to guarantee, with
the maximum visual comfort and the best colour
rendering of the lighting, a greater environmental
sustainability and a considerable reduction in
light pollution and consumption, with all that
this entails in terms of reducing public spending
and health benefits for citizens: following the
innovations made to the systems in Piazza
Palazzo and Piazza IX Martiri, the Municipal
Administration of L’Aquila was able to certify
over 46% energy savings, with an equivalent
reduction in CO 2
emissions into the atmosphere
of 2.5 tCO 2
per year, corresponding to 5.44 MWh.
Citelum’s experience in L’Aquila has been
extremely significant in terms of our vision,
for which technological innovation is to be
considered a tool rather than an end in itself:
a tool through which Cities can enhance their
assets, responding effectively to the challenges
associated with the growing urbanization,
the consequent evolution of lifestyles, and the
need to combine tradition and renewal. In the
case of L’Aquila, however, there was an additional
factor: the pride of having contributed, for
a small part, to the rebirth of one of the pearls
of Italy, a City that faced the trauma of the 2009
earthquake by finding a new starting point and
an opportunity for improvement.
