BioDesign laboratory (ADDA) focuses interest on observing how biological organisms achieve complex emergent structures from simple components. The structures and forms generated by natural systems are analyzed and understood as hierarchical organizations of very simple components (from the smallest to the largest), in which the properties arising in an emergent manner are rather more than the sum of the parts In our constantly developing society, with its demanding market, the use of new production technologies in fields such as engineering is becoming more frequent, and research is conducted to create state-of-the-art materials, such as composites, which open up new possibilities of use and performance, and contain the logic of living materials. In the field of architecture, even more rightly, we are forced to regain this sensitivity in observation and research, and learn the lesson of nature on the act of formalizing and metabolizing. Our objective is to learn and explore this knowledge to then transfer it and apply it to the design process of architecture and spaces.

[EMERGENT BEHAVIOR] Cybernetics is a broad field of study which analyses how digital or biological processes information reacts to information or changes and how it can be changed and improved. One of the concept studies of cybernetics is emergence. Physicists, scientists, artists and systems theorists define emergence as the way how complex systems and patterns arise out of multiple relatively simple interactions. Psychologist G.H. Lewes was analyzing the difference between result and emergence; both of them seem to be the sum of certain components. Although, according to the psychologist, every resultant can be resoluble into its components, because they are homogeneous and commensurable, so cannot be reduced to their sum or difference. Although, later on two types of emergency were defined and according to them emergent property was diminishable. First type of emergence is weak emergence. It is a type of emergence in which the emergent belonging is reducible to its individual components.

Second type is strong emergence in which the emergent belonging is irreducible to its individual components. American biologist and complex systems scientist Peter Andrew Corning widens the definition of emergence. He writes that emergency is not driven by specific rules and laws, which in fact have no casual efficiency. In other words, rules and laws do not generate anything. Good example is a chess game: here you cannot use the rules to predict history; also you cannot reliably predict the next move. The reason is that the system includes more than the rules. It also includes players and their movement by movement decisions which are chosen among various different options. Another example would be paths which urban planners or architects are designing for public or private spaces. They are equal to the rules in the chess game. Although, pedestrians always pick their own route and usually form a different path.

[GROWTH & FORM] Inspecting a sunflower head, one may notice first the diamond-shaped seeds that tile the disk. Families of spirals catch the eye, and if one counts the numbers of spirals in each family, one typically arrives at successive members of the Fibonacci sequence 1, 1, 2, 3, 5, 8, ... The spiral families seem to blend into each other so that lower members of the Fibonacci sequence are observed near the center of the disk and higher numbers as one works one’s way out. Yet, there is a self-similarity in that locally the pattern is nearly the same throughout the disk. The arrangement of elements such as seeds on a sunflower, leaves on plants, bracts on a pine cone, or aeroles on cacti, is referred to as phyllotaxis, and it has long been observed that only a few classes of phyllotactic patterns are commonly observed in nature. The same Fibonacci-spiral pattern, for example, is commonly observed on pine cones and cacti. Why is it that only a few patterns dominate? And what chemical or physical mechanisms are behind the formation of these patterns?

Through mathematical models for the formation of phyllotactic patterns based on biochemical and biomechanical mechanisms, we suggest ways to understand both universal aspects of phyllotactic patterns as well as how interacting mechanisms can cooperate or compete to produce the array of patterns seen in nature.

societies, and so on. In a fractal system, semi-autonomous agents interact according to certain rules of interaction, evolving to maximise some measure like fitness. The agents are diverse in both form and capability and they adapt by changing their rules and, hence, behaviour, as they gain experience. Fractal systems evolve historically, meaning their past or history, i.e., their experience, is added onto them and determines their future trajectory. Their adaptability can either be increased or decreased by the rules shaping their interaction. Moreover, unanticipated, emergent structures can play a determining role in the evolution of such systems, which is why such systems show a great deal of unpredictability. However, it is also the case that a FS has the potential of a great deal of creativity that was not programmed-into them from the beginning. Considering an organisation, e.g., a hospital, as a FS shifts how change is enacted. For example, change can be understood as a kind of self-organisation resulting from enhanced interconnectivity as well as connectivity to the environment, the cultivation of diversity of viewpoint of organisational members, and experimenting with alternative “rules” and structures.

The formation of the seeds creates three different spirals; gently sloping (21), steeper spirals (34) and very steep spirals (55) – all of these are consecutive Fibonacci numbers. The Golden Ratio (1.61803…) is the best solution to this, and the Sunflower has found this solution in its own natural way. 18

[GENERIC vs. GENERATIVE] Applied research to study connectivity with different strategies

Applied research examines a specific set of circumstances, and its ultimate goal is relating the results to a particular situation. That is, applied research uses the data directly for real world application. The proposal is to reach the ultimate goal by applying three different empirical methodologies or strategies and compare them when the goal is achieved. + Goal The goal is to predict a specific behavior in a very specific setting with 3 Strategies to reach from Point A to Point B.

INTEGRAL ENVELOPES Minimal Nets


[FORM FINDING]

They are form active tension systems which transmit only tensile forces and shape according gto applied forces into minimal nets. Minimal surfaces have gradually been translated from the field of mathematics into the architectural design research due to their remarkable geometric properties. The simulations of soap films or protein folding are only some of the many applications in various fields. Characterized by the interaction between the geometry and forces within a material system; Form Finding focuses on the relationships between the components more than the component itself. The aim of the study is to understand how tension works un the basic cable systems and gradually proceed to more complex configurations. For a cable system to be in tension and structurally active, there needs to be an equilibrium of tensile forces throughout the system. The system’s shape and extent must be the part of the solution which is defined through the displacements of particular boundary points and pre tensioning forces. The final form is the resultant of equilibrium of forces.

[CASE STUDY] River Basento Bridge | Sergio Musmeci

The mathematical interaction between force and function led to the formation of the Sergio Musmeci Viaduct. The Basento Viaduct, a bridge built in 1969 in Potenza (Italy), is a continuous surface minimized in its area while maximizing its structural function. Sergio Musmeci managed to create a magnificent concrete surface whose aesthetics directly derived from its efficiency studied using analog models and form-finding techniques.

Musmeci said his Basento River Bridge was not resolved as an arc, in terms of structural template, but as a vault, or rather as a membrane evenly compressed reinforced concrete with 30 cm thick, excluding the ribs along the edges, which were meant to be used as a walkway for pedestrians, meeting the requirements of the minimum structure, mathematical and technical problem Musmeci subsequently analyzed in his book “The static structures”

[MOVEMENT IN THE PROLIFERATION] The internal frame is now continuous. The modules are arranged in the specific pattern to create the desired movement of the boundary conditions from the configuration. There are 2 kinds of movements possible : 1. When the Z axis is rigid; the boundaries in X and Y axis are displaced (as in the previous experiments). (When all axes are bendable, there is little movement in the Z axis in Y direction and X axis in Z direction) 2. When the X and Y axes are rigid, the Z axis is deformed.

[MOVEMENT IN THE PROLIFERATION] There are 2 kinds of movements possible through this configuration. 1. When the Z axis is rigid; the boundaries in X and Y axis are displaced (as in the previous experiments). (When all axes are bendable, there is little movement in the Z axis in Y direction and X axis in Z direction) 2. When the X and Y axes are rigid, the Z axis is deformed. This deformation is studied and parametrisized in the following experiments.

63





[MOVEMENT IN THE PROLIFERATION] The actuation points being the midpoints of the internal boundaries, there can be linear actuators which change in length attached to them. When the X and Y axis are rigid, the deformation of the Z axis is much larger. The X and Y are kept less rigid to restrict the movement to 5 degrees of deflection. Following configuartions can be achieved through 5 degrees of deflection.

“Cartography is a practice which, in its efforts to describe reality, is revealed to us as partial, specific and concrete interpretation. Any representation of reality is simply one possible representation of reality, one manner [intentional or not] of reducing reality to one limited aspect , making certain traits or characteristics evident. But it is precisely by virtue of this partiality, specificity and limited quality, that the mapped reality becomes apprehendable”. Roger Páez i Blanch, Operative Cartographies and Behavioural Maps

[SITE AND FIRST IDEAS]

The region of La sagrera is clearly divided into two distinct neighbourhoods by an urban scar in the site which exists for several decades. Since this region was never developed, the two neighbourhoods were never fully conneceted and developed separately giving different charachteristics to each.

Sant Marti has a lot of industries and vacant plots which are currently used for parking and temporary storage for the contruction of the upcoming train station of La sagrera. These places will eventually be urban voids and are key points for potential development

Establishing more connection points and focusi ng on potential areas of development which can compliment the development of the train station are the key objectives

[SEMIOLOGICAL FIELD] Leyend

As investigated across disciplines, scientific theories and mostly quantum physics are based on shaky grounds, as they contain ‘unobservables’ i.e. space, time, potentials, fields, waves with no reference to matter. On the other hand, we acknowledge that emergence stems from complexity; from the invisible and unsettling potentiality fields between the transitional states of transformation and exchange. Consequently, we may argue that such a condition of emergence calls not only for new modes of presentation, interaction and aesthetics in relation to the issue of boundary, but also, of understanding reality per se. The construction of this language must proceed step by step, oscillating between syntactical and semantic advances. This is made possible via parametric 88

agen-based modelling that realizes the signifying relations as associative functions that systematically make agent behaviours dependent on architectural features. At the same time the pragmatic layer is anticipated as the (never fully predictable) social appropriation process that commences when the design spaces are finally utilized and re-utilized. Morphological features, as well as colours and textures that, together with ambient parameters (lighting conditions), constitute and characterize a certain territory can now influence the behavioural mode of the agent. Since the ‘meaning’ of an architectural space is the (nuanced) type of event or social interaction to be expected within its territory, these new tools allow for the re-foundation of architectural semiology as parametric semiology. The semiological project therefore implies that the design project systematizes

all form-function correlations into a coherent system of signification. A system of signification, in turn, is a system of mappings (correlations) that map distinctions or manifolds, defined within the domain of the signified (here the domain of patterns of social interaction), onto the distinctions or manifolds, which are defined within the domain of the signifier (here, the Attractor points being the amenities and the High density points on the Node being the Repellers) This system of signification works if the programmed social agents(pedestrians) consistently respond to the relevantly coded positional and morphological clues in such a way that expected behaviours can be read off the articulated environmental configuration.

Selection

These field lines represent the connection between the high density points and the Attraction points. The effect of these lines on the site conditions are studied and the physical possibilities shortlisted. These connecting pathways are mediators between the amenities/infrastructure and the points with highest density of movement of people. These pathways are intervened to informalise the infrastructure and create a seamless flow from the enclosed amenities to the more open socially interactive areas. For example, the schools are connected to the more socially interactive areas like the church and the old age homes to encourage more social interaction between diverse age groups. The open spaces connected to the schools have libraries, open and informal study areas, etc. The high density points connected to the open spaces have retail spaces and iterant spaces. 94

[PROPOSED INTERVENTION] The “Parasite� to the train station is an extension to the proposed stationat la sagrera to include the dire need of connectivity in the site. The two entry/exit locations from the train station are weaved through an interesting spacial mediator where there are many iterant spaces for exhibitions, festivals and interactive museums. This structure becomes a cultural and social hub in a train station which has a high density of movement, yet doesnot affect its functioning. It is proposed as a seed for future development as the further interventions proposed are arbitary to the growth and development of this Train station.

[OPTIMIZATION]

The Ribs are manipulated with the angles of intersections in the boundaries. The structure can be made more or less porous depending on the weather and comfort conditions pre-determined. The angle of incidence of the sun plays a major role. During Summer, the direction of the ribs is against the sunlight making the structure less porous, hence restricting the entry of sunlight. Whereas in winter, more sunlight in allowed to enter the structure.

[ROOF STRUCTURE - CONFIGURATIONS] Solar tracking - The module is fixed with flexible solar panels on the internal boundaries. The actuators are programmed to track the solar position to optimise the solar gain to generate power for the parkland and the train station landscape. Density - Depending on the number of people (calculated by the number of trains), the Roof structure in the train station configures itself to maintain the internal temperature depending on the volume and porosity
