Photovoltaic panels on the roofs of the buildings instead produce the electrical
energy; this RES provides the lighting for common areas, while solar panels
provide half of the required heat for sanitary hot water production for residential
use. Hammarby Sjöstad is provided with a closed chain re cycling system, where
inhabitants 'contribute' up to 50 % to the Energy generation simply by producing
waste, while the remaining 50 % is covered by RES: solar, hydro-electric and
wind generation.
In summer 2005 a filling station for hydrogen cars supply was completed, there
cars were already produced and circulating in Sweden at those times, such as the
eco-transportation system based on ethanol buses that are replacing the entire
municipal fleet.
The added value of this experience is an 'integrated' design of urban settle-
ments namely a process involving technicians (urban planners and designers) the
public administration, the citizens, the business world.
Since the very starting phases of the project, it is required to connect the master
plan, the infrastructural projects and the environmental objectives. Hammarby
Sjöstad, is the main expansion area of the city in recent times and it has been built
following this methodology.
The different authorities, administration office representatives and private
stakeholders have followed this new conceptual approach for which the first
interest is the ''common good''.
Today the Hammarby Sjöstad project is not yet concluded, but it can be said
that most of the objectives have been reached and that it can be considered a best
practice showing the intrinsic potential of this design approach.
Another large realization still to be completed and at an early stage as compared
to HS is the Royal Seaport again in Stockholm that will let the city reach another
important target.
The area of new development will concentrate on sustainable mobility solu-
tions, efficient building processes, and energy saving also through energy effi-
ciency solutions.
In Stockholm 2030 will be world leader for what concerns the development and
implementation of new technologies in the field of Energy and environment: since
now the building of new districts, that will have the function of models at planetary
scale. Stockholm Royal Seaport will be a 'shop window' for sustainable urban
building where innovative and creative solutions will be experimented as well as
new technologies, with the ambition that the urban district will be an environ-
mental model at global level for the other cities. Of course the other experiences
such as Hammarby Sjöstad and the other international experiences are the back-
ground for any new proposal and implementation.
The German city of Freiburg (Fratini
2013
) has made of the environmental
commitment a slogan since the sixties. It is very well known the Vaubau district—
an urban area of 15 hectares—where 5,000 people live not holding a car or at least
almost not using it. The shape of the district, its layout, the distribution of the
functions and the public transportation means allow this.
