Tranquil state
• A tranquil stateis considered not in absolute value but in a
change in state, this change should be towards decreased
arousal measured in > SCR, > Heart rate
• The largest percentual difference towards reduced arousal is
consideredto be the stimulus leading to the highest tranquil
state.
62. International Society of Biourbanism - Summer School 2014
Tranquil response
• A tranquil response is any response that contribute to the
level of a tranquil state. Meaning any: > SCR, > Heart rate(v)

differentiation based on the stateand trait of an individual.”
• “The responses to these “architectural” stimuli are predictable through
patterns and codes. By understanding these patterns and codes we can
anticipate how humans will respond, we know this because humans are
natural beings which we start to comprehend, we can design urban
spaces from which we can positively influence the behaviour and usage of
a space to enhance personal and societal well being.”

"To find a form that accommodates the mess, that is the task of the artist now."
- Samuel Beckett
85. International Society of Biourbanism - Summer School 2014
Paracity is a positive organic tumour in the mechanical tissue of
Taipei. While it is leaching and processing the industrial and
organic waste of the city, it is gaining momentum in its
growth and becomes more and more important to the static
industrial urbanism.
Paracity is an alternative reality within the industrial
development and will start treating the city the same ways as
the urban acupuncture points of illegal communitygardens
and urban farms of Taipei do today.
Paracity has the ability to become a network of biourban
acupuncturetuning the whole industrial city towards the
organic, ruining the industrialism on its way to become part
of nature, the Third Generation City.
86. International Society of Biourbanism - Summer School 2014
Paracity is a third generation city, an organic machine, urban
compost,which is helping the industrial city to transform into
being part of nature.
88. International Society of Biourbanism - Summer School 2014
Bio-energy
The main energy source for the Paracity is bio-energy, which is using both
treated organic waste and sludge from Paracity and surrounding Taipei
and especially biomass that is harvested around Paracity and on the flood
banks of the Taipei rivers. The fertile flood banks, flood plains and storm
water channels provide ideal cultivation areas for fast growing biomass
plantations. The vegetation will be harvested by boats and then shipped
to Paracity Bio-Energy Facility. The growing of the biomass on the river
banks will also benefit on the natural river restorationthroughroot
cleansing of sediment pollution and the biomass will have a positive
impact on the Taipei micro climate and urban ecology.
90. International Society of Biourbanism - Summer School 2014
Social Development
Where in nature a tree will not grow under another tree or too near another
tree because they would be fighting for each others light, ground and
water in society we must live according to similar innate rules whereby
we prove selfless and show an interest in the well-being of others. A
paracity musttherefore grow according to need rather than desire.
If you think of a city no matter the scale we often do not interact with those
in our close proximity. As individuals we have the innate trait to want to
help others whether it be because we care or simply because it makes us
feel good. This gets lost in an individualistic city where we find it more
difficult to extend help to a stranger but also where there is often no one
to recognise and praise your efforts.
93. International Society of Biourbanism - Summer School 2014
The post-industrialfleet of bio-vessels can travelalong the Taipei river system and is
ready to start the biourban restorationprocessalso from other hot-spots of the river
city. The environmentaltechnologybarges provide solutionsfor:
• Waste water treatment of Paracity and of the surrounding Taipei
• Water purification.The infrastructuralwater circulationis originatedfrom the
pollutedDanshuiRiver.
• Sludge treatment for fertilizer and bio-energy.
• Closed circuit aquaculture.
• Recycling of construction waste.
• Recycling of organic waste for fertilizer and bio-energy.
94. International Society of Biourbanism - Summer School 2014
Paracity will use purified water from the pollutedDanshui River. After chemical
bacteriabased primary treatment the water is pumped to the roof gardens for
oxygenationandtaken by gravity to the farms and gardens.
95. International Society of Biourbanism - Summer School 2014
Adaptability
The pilot-project of the Paracity is designed in Taipei, but the solution
is developed to work in different locations around the world.
Paracity offers an alternative for the Chinese strategic urban
planning to start ecologically harmonizing the growing river cities of
China. And Paracity can be used as urban acupuncture for the
emerging cities of China and elsewhere.
Paracity can grow along the Oshiwara chain of slums in Mumbai
providing better living conditions, cleaning up the Oshiwara River
and more effectively treating the urban waste that is flooding in
from the surrounding city.
Paracity can parachute into Nairobi and start growing from the fertile
top-soil of the slums. Paracity should grow into the favelas of Brazil
and start celebrating the local knowledge of these organic
communities. Paracity is organic, adaptable and welcomes local
knowledge. The city is built by hands of a high diversity of different
people.
97. International Society of Biourbanism - Summer School 2014
Paracity has a lot of holes, gaps and nature in-between
houses. The system is ventilating itself like a large scale
beehive of post-industrial insects. The different
temperatures of the roofs, gardens, water bodies and
shaded platforms will generate small winds between
them and the hot roofs will start sucking in breeze
from the cooler river. Also the individual houses should
follow the traditional principles of bioclimatic
architecture and not rely on mechanical air-
conditioning.

to study the chaos and disorder of
their contemporary cities that
strongly contrasted with the
efficient and abstract model of the
modern city, particularly the use of
public spaces.

Placemaking takes root when a
community expresses needs and
desires about places in their lives,
even if there is not yet a clearly
defined plan of action.

and how are they connected?
Are there places that should be more

create a network:
the power of 10
One great place is not enough, need
a number of them to create a truly lively
city
Power of 10 is a framework for
communities and stakeholders
principle is: starts from smallest scale to
accomplish big things
The need of a network of good places at
different scale:
Place > neighbourhood > city > region
is a collection of interesting communities
on a regional scale by linking towns and
cities, with major public spaces and mixed-
use neighborhoods serving as the
connections.
power of 10
122. Angelica Fortuzzi, Architect, PhD | Summer School 2014
The core idea is:
any great place itself needs to offer at
least
10 things to do
or 10 reasons to be there…
a place to sit, playgrounds to enjoy, art to
touch, music to hear,
food to eat, history to experience, and
people to meet.
A park is good. A park with a fountain,
playground, and popcorn vendor is
better. A library across the street is even
better, more so if they feature storytelling
hours for kids and exhibits on local
history. If there’s a sidewalk café nearby,
a bus stop, a bike trail, and an ice
cream parlor, then you have what most
people would consider a great place.

1. The Community Is the Expert
The important starting point in developing a concept for any public space
is to identify the talents and assets within the community – inviting
people into the process - who have an interest or stake in a particular
place, such as those who live or work there - is crucial in deciding how to
develop or improve a place.
In every community there are:
- historical perspective,
- valuable insights,
- how the area functions,
- understanding of the critical
issues,
- what is meaningful to people.
guidelines: 11 principles
125. Angelica Fortuzzi, Architect, PhD | Summer School 2014
2. You Are Creating a Place, Not
Just a Design
Creating a place entails a broader view
that goes beyond design; a successful
public space possesses four key
attributes:
1. accessibility,
2. activities,
3. comfort by physical changes
4. and sociability
Goal: create a place with a strong sense
of community and a comfortable image,
with setting and activities and uses.
11 principles
126. Angelica Fortuzzi, Architect, PhD | Summer School 2014
3. You Can’t Do It Alone
A good public space requires more
resources and expertise than any one
individual or organization can offer.
4. TheyAlways Say “It Can’t
Be Done”
When an idea stretches beyond the
reach of an organization and and
someone says, “It can’t be done,” what
that usually means is, “We’ve never
done things that way before.”
5. You Can See A Lot Just by
Observing
When people observe a space, they
learn about how it is actually used,
rather than how they think it is used.
11 principles
127. Angelica Fortuzzi, Architect, PhD | Summer School 2014
6. Develop A Vision
A vision for a public space should be
defined primarily by people who will live,
work around, and use the space.
7. Forms Support Function
The most successful places grow out of
understanding what a space needs to
offer so that people will use it. By
following and incorporating the uses
articulated by the community, a designer
can not only make the space interesting to
look at and be in, but also very functional.
8. Triangulate
The concept of triangulation relates to
locating elements in such a way that the
chances of activity occurring around them
is greatly increased. For example, if a children’s
reading room in a new library were located next to a
playground in a park with a food kiosk, more activity
would occur than if these facilities were sited separately.
11 principles
128. Angelica Fortuzzi, Architect, PhD | Summer School 2014
9. Lighter - Quicker - Cheaper
Many great plans become bogged down
because they are too big, cost too much,
and take too long to happen.
Short-term actions, like planting flowers, can
be a way of not only testing ideas, but also
giving people the confidence that change is
occurring and that their ideas matter.
10. Money is Not the Issue
All too often, the lack of money is used as
an excuse for doing nothing. In fact, too
much money often discourages the
inventiveness, creativity, and persistence
required to create a great place.
11. You are never finished
About 80% of the success of any public space
can be attributed to its management. No
matter how good the design of a space is, it
will never become a true place unless it is
cared for well.
11 principles
