destroy the nitrogen and phosphor
and oxygen is added through air
pipes. Finally the water is subjected
to sunlight that takes part in its steri-
lization. As soon as the water has
passed through these “water-trees“,
A it runs through different passages
towards the Gavia river or to “water-
trees", B. These are located in many
areas of the park of different depths
and shapes, amount of water and
movement. “Water-trees", B are
basic types, intended to be places
for different pastime activities so
that the public can enjoy the feel of
the water.
As a whole, the “water-trees“ main-
tain the natural eco-system as a
peaceful home for birds, insects,
animals and water plants. Some
123 types of trees are planned,
sheltering and providing food for
the birds. In addition the lighting is
controlled so that it does not pollute
the wild eco-system. Solar power is
used to produce electricity for low
red lights that do not blind people
walking through the park.
Economical use of
power
ln the design of the public garden
emphasis is put on reducing the
need for natural resources, not only
in íts construction but also while it
is being used. The design encour-
ages the use of reclaimed materials
that require little energy in manufac-
ture and that water and energy are
economically used. To eliminate the
movement of soil it is guaranteeed
that all the excavated soil is used
on site. Economical maintenance is
also part of the design by permitting
vegetation to grow freely without
strict adherence to form and the
choice of plants, by mixing differ-
ent types depending on each area
and that intended activities can add
diversity to the eco-system.
Toyo Ito is designing a public park
where natural circulation of the
water is used to produce energy
while it goes through a purification
process. The circulation is closed
by creating different eco-systems
where the concept sustainability is
understood with a wider meaning
than improving the environment and
using energy economically.
The architect interprets sustain-
able design as a wider concept.
It also takes into account aspects
like natural resources, environment,
society and the use of capital. A
sustainable project not only reduces
the impact on natural resources and
treats the envioronment gently but
also impacts society in a positive
way and is also economical. ■
