VARTOV: A Shadow Play.
The
stranger rose, and his shadow across the street rose with him. The
stranger turned around, and his shadow turned too. If anyone had been
watching closely, he would have seen the shadow enter the half-open
balcony door in the house across the way at the same instant that the
stranger returned to his room and the curtain fell behind him.

Christian Andersen, ?The Shadow, 1847.
01. Concept: a shadow play.
Our proposal conceives Vartov's square
as a ?shadow play?. A shadow play of the city life and its
narratives. Lights and shadows are indeed indicator of life
activities in a city. Light works as attractor for daily as well as
nocturne practices and drives activities around public spaces.
This duality is actively structured in
our proposal. The square's pavement is designed with a special type
of concrete (called TX) that can oxide the polluting substance in the
air such as oxides of nitrogen and PM10. This concrete operate trough
a photocatalytic process. Its performance is logarithmically related
to the amount of direct sunlight on the pavement. Covering the whole
square with such concrete, we have script the ?shadow play? of
the surrounding buildings on the pavement and their overlapping areas
during equinoxes and solstices. This allowed us to spot the most
lighted areas during the year and draw a pavement pattern. In our
project this corresponds to the concrete's performance so that the
square's program could be organised accordingly, preferring to
concentrate the pedestrian activities into the most lighted areas
where the photocatalytic performance of the TX is more efficient. The
square pattern is therefore conceived as a diagram of the TX
performance that reveals the program of activities as an urban shadow
play.
We foresee to realise the pattern with
prefabricated tiles on site and giving them ten degrees of pigment
from white to black that represent the range scale of the concrete's
performance. The tiles have a triangular shape that measures the
public space. Sixty-four tiles will measure two square meters, which
we consider as minimal unit of land use in a public space.
02. Program: the shadow script.
The Town Hall shadow plays a major role
in the play. It occupies a large side of Vartov's square. We decided
to program this area as a switching speed platform to interface
pedestrians and cyclist mobility with motorized services. Here we are
planning to concentrate the tourist's bus park, bicycle-taxis,
Electric-cars Park and business Cars. This inter-modal platform
should support the public role of the Town Hall and its different
services. Pedestrian paths as well as bus stops are protected from
the rain and wind with light structures that integrate photovoltaic
panels on their shelters.
Opposite to this shadow there is an
open space right in the middle of Vartov's square. The program of
this space is loose, furnished with mobile chairs that can be also
used for public events. All the main pedestrian paths stretch along
this area which view is closed by the continuity of the facades in
the background. These pedestrian paths are remarked with fixed
benches along the way. In this area, that is open to the nature
forces we have foreseen the possibility to introduce mobile
windshield that can be placed according to the wind direction as well
as delimitate some inner space during public events. Windshields will
be provided with small wind turbine propellers to that they can
accumulate energy that could be used for public use.
As a tuning point between these two
areas an artificial rock is designed. This would allow a privileged
viewpoint over the urbanscape of the square in both sides. A place
where people could rest and sunbathe in warm summer days and at the
same time protect from visual and acoustic noise of the switching
platform and shield the square against the wind.
The whole square is designed with the
rhythm of the tiles that reveal the active performance of the
concrete. These tiles can host also the rainwater drainage as well as
the electrical supplies needed for the events that might take place
on the square. The surface of those tiles will be designed in order
to mark the pathways and create a vibrant surface during the long
Scandinavian sunsets. The surface treatment will drive visual and
tactile attention to the main paths so that anybody could clearly and
safely find their way. This surface will be durable and prevent the
formation of slippery areas during the winter or rainy weather and
will be easily accessible to wheelchairs users.
3. Construction timing: a shadow
play in three acts.
The shadow play will be realised in
tree acts. The first one will be ?The Town Hall Shadow?. The part
of the square characterised by this monumental presence where we
decided to place all the services in a speed-switching platform. We
consider this as a priority that needs to be fulfilled so that can
serve the activities of the city at large from the beginning.
The second act will be ?The Vartov's
light?, as the side of the square with more direct sunlight that
will be dedicated to loose and flexible program of activities. And
finally the third act will be ?Vartov goes underground?, as a
part of the square where the subway station will be realised in the
future. This area is conceived as an open space of transition
characterised by the hard surfaces of the surroundings, delineated by
the roads and the subway access.
4. Lights.
Shadows as well as artificial lights
play an important role in the set design of this play. This role is
given to the catenary that supports the lights. We are proposing here
a new interpretation of the traditional catenary that follows the
geometry of the pavement's pattern and guide the sight towards the
areas of activities and landmarks or special urban space such as
Grnegden and Rhushaven. The catenary will draw lines of
shadow that complete in a dynamic way the pavement and create
different geometry during the different seasons. The catenary will
also host surface for light reflection at night. These surfaces could
be outsourced as public art project. They could include figures of
Andersen?s ferry tales so that they could play as shadows during
the day and be highlighted at night as floating figures into the open
space of the square.
