The Cartesian-Newtonian paradigm contends that the
physical world is made up of basic entities with distinct
properties distinguishing one element from another.
Isolating and reducing the physical world to is most basic
entities, its separate parts, provides us with completely
knowable, predictable, and therefore controllable physical
universe. . .
.The Cartesian-Newtonian paradigm contends that the physical
universe is governed by immutable laws and therefore is
determined and predictable, like an enormous machine. In
principle, knowledge of the world could be complete in all its
details. (De Jong)

The science of the last 150 years has profoundly shaped our
culture and our civilization
This has changed:
 Our Knowledge

 how we think and feel,
 how we view our social and political institutions,
 the findings of science have intentionally separated the
process of forming mechanical models of physics from the
process of feeling

Hyperreality describes an inability of consciousness to distinguish reality from a
simulation of reality, especially in technologically advanced post-modern societies.
Hyperreality is seen as a condition in which what is real and what is fiction are
seamlessly blended together so that there is no clear distinction between where
one ends and the other begins

essential problems of architecture
1. value, that cannot be separated from the main task of serving
functional needs
2. issue of context — a building grows out of, and must complement, the
place where it appears.
3. issue of design and creation - processes capable of generating unity.
4. issue of human feeling: no building can be considered if it does not
connect, somehow, to human feeling as an objective matter.
5. issue of ecological and sustainable and biological connection to the
land.
6. issue of social agreement regarding decision making in regards to a
complex system
Open PISM

We believe that
architectural (urban) design
can be founded on scientific principles
that are analogous to structural laws in
theoretical physics and biology
Open PISM

The last scientific developments of the past decade, such
as fractals, complexity theory, evolutionary biology, and
artificial intelligence give us an idea of how human
beings interact with their environment.
EVIDENCES
organisms, computer programs, buildings, neighborhoods,
and cities share the same general rules governing a
complex hierarchical system.
All matter (biological as well as inanimate) organizes
itself into coherent structures.
The human mind has evolved in order to adapt to
complex patterns in the natural world, so the patterns
we perceive around us influence our internal function as
human beings.

The reform in thinking is a key anthropological and
historical problem. This implies a mental revolution
of considerably greater proportions than the
Copernican revolution.
Never before in the history of humanity have the
responsibilities of thinking weighed so crushingly on
us.

The Meaning of a Systems Approach
A "systems approach" means to "approach" or
"see" things (or phenomena) as systems
A system is
"a group of interrelated, interdependent, or interacting
elements forming a collective unity" (Collins English Dictionary, 1979, p.
1475)
"a complex whole" (The Concise Oxford Dictionary, 1976, p. 1174).

Every complex system has a
hierarchical structure; i.e.,
different processes are occurring
on different scales or levels.
Connections exist both on the
same levels, and across levels

According to Adrian Bejan, professor of mechanical engineering at Duke
University, in Durham, North Carolina, the human eye is capable of
interpreting an image featuring the golden ratio faster than any other

Bejan shows that these shapes
emerge as part of an
evolutionary phenomenon
that facilitates the flow of
information from the plane to

the constructal law of
generation and evolution of

allometry, also called
biological scaling, in
biology, the change in
organisms in relation to
proportional changes in
body size.
An example of allometry can be
seen in mammals. Ranging
from the mouse to the
elephant, as the body gets
larger, in general, hearts beat
more slowly, brains get bigger,
bones get proportionally
shorter and thinner, and life
spans lengthen.
Open PISM

Allometry happen in fractal structure and this law are
ubiquitous in nature.
In “Scaling laws in cognitive sciences” scholars have
demonstrate that the scaling laws pervade neural, behavioral
and linguistic activities suggesting the existence of processes
or patterns that are repeated across scales of analysis.

An outdoor space is positive when
it has a distinct and definite shape
 it has been shaped over the time by people
 it has therefore taken a definite, cared for shape with
meaning and purpose
 Every bit of space is very intensely useful
 There is NO leftover waste space which in not useful
Open PISM

POSITIVE SPACE
Another way of defining the difference between "Positive" and
"negative" outdoor spaces is by their degree of enclosure
and their degree of convexity.
space is non-convex, when
some lines joining two points lie
at least partly outside the space
space is convex when a line
joining any two points inside
the space itself lies totally
inside the space.
Open PISM

POSITIVE SPACE
degree of enclosure
Positive spaces are partly enclosed and the "virtual" area
which seems to exist is convex.
Negative spaces are so poorly defined that you cannot really
tell where their boundaries arc, and to the extent that you can
tell, the shapes are non-convex.

POSITIVE SPACE

CONCLUSION
i. When environments are built by biourbanism approach
(complexity + biological roots) they will of their own accord
become sustainable.
ii. Adopt incremental and bottom-up strategy
iii. Good form-based on “genetic codes” can generate healthy
environments (geometry, patterns  biomimicry)
iv. Urban community is a consequence of a successful public
space
v. Small-scale funding introduces a bottom-up component of
development to balance the usual top-down process
vi. building to enhance the life of sites
vii. Re-configure road structure for optimum pedestrian
connectivity
viii. Create mixed-use urban centers

BIOURBANISM AS NEW
EPISTEMOLOGICAL
PERSPECTIVE….
Open PISM

OK, but… what is Biourbanism?
The first definition of the term “biourbanism” has been given in
2010 by the philosopher and psychologist Stefano Serafini (ISB),
the bio-statistician and expert in complexity theory Alessandro
Giuliani (Italian NIH), the architects Antonio Caperna and Alessia
Cerqua (Roma Tre University), and the mathematician and urban
theorist Nikos A. Salingaros (University of Texas at San Antonio)
Source: www.biourbanism.org/biourbanism-definition/.
Open PISM

Biourbanism focuses on the urban organism, considering it as a hypercomplex system, according to
its internal and external dynamics and their mutual interactions.
The urban body is composed of several interconnected layers of dynamic structure, all influencing
each other in a non-linear manner. This interaction results in emergent properties, which are not
predictable except through a dynamical analysis of the connected whole. This approach therefore
links Biourbanism to the Life Sciences, and to Integrated Systems Sciences like Statistical
Mechanics, Thermodynamics, Operations Research, and Ecology, in an essential manner.
The similarity of approaches lies not only in the common methodology, but also in the content of the
results (hence the prefix “Bio”), because the city represents the living environment of the human
species. Biourbanism recognizes “optimal forms” defined at different scales (from the purely
physiological up to the ecological levels) which, through morphogenetic processes, guarantee an
optimum of systemic efficiency and for the quality of life of the inhabitants. A design that does not
follow these laws produces anti-natural, hostile environments, which do not fit into an individual’s
evolution, and thus fail to enhance life in any way.
The morphology of urban structure follows its own intrinsic set of rules, analogous to the
rules determining biological growth and function. These rules arise from the process of self-
organization combined and balanced with direct intervention: two competing mechanisms of bottom-
up versus top-down design of urban fabric. Living urban regions complement and continue nature by
extending rules for biological growth. But just bringing nature into city centers is superficial, an “image
approach to planning” that reveals a basic lack of understanding of urban morphology. In fact, rural and
urban typologies follow very different rules and cannot be mixed. Most cities throughout history were
largely spontaneous, with interventions implemented later in an effort to organize a situation that had
grown into unmanageable complexity. Intelligent urbanists discover the rules for spontaneous urban
growth from watching a city evolve and from studying historical urban fabric. Only with the arrogance
and iconoclasm of the twentieth century did humankind empower “unintelligent experts” who were
ignorant of organic urbanism to plan our cities, with disastrous results.
Open PISM

Biourbanism acts in the real world by applying a participative and helping
methodology. It verifies results inter-subjectively (as people express their
physical and emotional wellbeing through feedback) as well as objectively (via
experimental measures of physiological, social, and economic reactions).
The aim of Biourbanism is to make a scientific contribution towards:
(i) the development and implementation of the premises of Deep Ecology
(Bateson) on social-environmental grounds;
(ii) the identification and actualization of environmental enhancement according
to the natural needs of human beings and the ecosystem in which they
live;
(iii) managing the transition of the fossil fuel economy towards a new
organizational model of civilization; and
(iv) deepening the organic interaction between cultural and physical
factors in urban reality (as, for example, the geometry of social action, fluxes
and networks study, etc.).
Open PISM

Biourbanism adds to such a scientific trend the connection to life
sciences, and their new model grounded on the direct role of chemical–
physical rules in designing the living systems. Concepts like biological
periodicity, self-evolution, laws of form, Constructal law, and
systemic integration can be very helpful to understand how cities
grow, unfold, and live.
In particular, the systemic study of the morphogenetic processes –
introduced by Lewis Wolpert at the beginning of the 1960s – allows us to
understand and facilitate the vitalising connections within the system,
and thus those between man and the environment, operating at different
levels on the geometry of space.
Different researches have proved the structural homology on which those
connections are based, noticing the experimental bases of the tributes
coming from the Gestalttheorie, the Tartu-Moscow-School, and the
generative grammar (e.g. the discovery of shared structures in
language, cognitive processes, brain) .
