ABOUT : ISABELLA ETNA I am Isabella Etna, second year Architecture and Urban

Planning & Design student at The University of Melbourne.

Born in Melbourne I am of Italian heritage and love to travel.

My design focus is informed by great thinkers throughout history who I believe narrate profound insight and a relevant way of seeing. 1 Buckminster Fuller saw the role of architecture as an instrument for experimentation, the search for a better understanding of nature’s’ operative principles rather than reinforcing long standing academic traditions or styles. Like Fuller I believe architectural disciplines require new and motivating circumstances from which a compelling idea can take hold. My work explores the belief that Architectural thought must speculate and confront these different circumstances unlike those it has preoccupied in the past.

I am interested in the cross over of the physical and digital realm. My experimentation with digital media and fabrication whilst a student at The Melbourne School of Design and during my final years at High School have set me on a trajectory to explore the interface of these co-existing realms.

2012 / 2013 / 2014 My interest in visual science , experimental strategies and statement artwork commenced with the digital manipulation of photographs with Adobe Photoshop and Illustrator.

2015 / 2016 My interest in propositions for the built environment based on lessons from Art History and key Architects were developed at MSD. I studied digital modelling softwares, including Mandelbulb 3D and Rhinceros 5 and drafting software, AutoCad. 2016 My interest in propositions for the built environment based on free energy and climate science have developed. My knowledge in advanced digital modelling softwares including Grasshopper and basic coding for ABB Robot Studio commenced.

Gaudi and Otto’s work reveal unique ways of thinking. They used flexible models to work with

freeform inspired by the effect of gravity on materials rather than a plan form design process2. In this way both architects demonstrate the “biotechnical”3 aspect of the natural world that can be represented in architecture.

Gaudi’s spatially elongated vertical voids had never been constructed nor conceived in the way contemplated by his experimental model of the catenary hanging cables. Gaudi created new ways to invent space with static forms so he could work out the fabrication methods during the construction stage. His untimely death had postponed the construction process until its recommencement in the 1980’s given the potential for computational design techniques to posthumously complete the Architect’s vision. The building is an important icon for Spain’s secular and religious buildings and its is the only Basilica of its kind ever built.

Likewise, Otto’s geometric tension structures and isotropic membranes had not been represented in this way before; as a deliberate spatial enclosure with their unique taut linear cable system.

Otto’s experimentation in non-linear forms derived from the properties of soap bubbles which he could visualise rather than be restricted to the limitations of the properties of physical reality, or gravity, and before he could digitally compute his models.

“The computer can only calculate what is already conceptually inside of it; you can only find what you look for in computers.” 4 - Frei Otto This has become an accepted method of practice for experimental building design in the fields of structural engineering and Architecture. This evolution from physical to computational experimentation has provided all design professions including Architectural Practice with an invaluable insight into the potential of computational techniques. Mark Burry postulates that both Gaudi and Otto‘s respective experimentations are now being understood as the pre-digital precursors, “countering any claim that Parametricism is a contemporary digital condition”5. Their work embraced new spatial representations not previously undertaken and necessitated the modeling of spatial forms that required new construction materials and techniques. What they signaled was the advent of the computational power necessary for the meaningful evolution of built form.

Computational techniques preserve architecture’s unique place as the innovator of built form

configuration and its assemblies - within the conceptual arts, as well as its “performative” responsibility as an environmental remediator. Computational design technology now makes possible the practice of architecture to deliver more responsive expressions of bioorganic systems found in the natural world.

In this irrefutable Age of man-induced climate change, the performative science capabilities that can be conceived in architectural thought necessitate the principle function of the Architect, and indeed all design professions, to be that of environmental remediator.

Digital design techniques improve the Architects visualisation horizon, and enable the innovation of dynamic super elastic building scale forms without limitation and whereby their composition encourage new Architectural research and development, with counterpart construction methods and material properties. This is particularly evident in architecture’s emancipation of performative assemblies of synthetic materials that can be programmed to compute intended environmental outcomes.

This gives rise to research carried out in design through material properties, whereby computation, “processing of information”8 plays an integral role. Performance oriented design reassigns the significance of a material's functionality - from the conventional expectations of the past - that the material is now treated to precede form9.

The consideration of materials is becoming more relevant to architectural practice because of

computational techniques. Antoine Picon argues that innovation should surpass "the superficial level of being a mere design trend or fashion"11 . This is exactly the downfall of 505 Studio's 'Pixel Building'.

The façade icons a flag waving ceremony without contributing to the buildings environmental agenda.

The 'Pixel' architects intended a buildings that would use and self produce eco-friendly energy in sustainable cycle as if to coexisist with the environment instead of opposing it, like other buildings do in the City of Melbourne. Furthermore, the architects pushed the idea that the building has "points for carbon neutrality"12 in a way that “bio technically inclined architects have worn the avant-garde mantle”13. Whereas the objective of specifying net clean energy outputs exceed ‘green star’ ratings is to extend the Architects command over computational techniques, has not been achieved. More appropriately architecture must adopt a more integrated approach than one that is limited to a suggestion of building science.

Neri Oxman, a pioneer of speculative performative experimentation, explores the notion of artificial

environments based on a cross over of computational and experimental materials for their sensory application in architecture. Oxman postulates that through "computational modelling of the natural principles of performative material systems "man can potentially create a second nature, or a sounder architecture with respect to material ecology"15. This principle is necessitated by the burden that all the world's urban areas account for just 1% of the Earth surface, but consume 75% of the total energy, and discharge 80% of green gas emission"16.

The appropriate application of Oxman's vision is represented by Kim and Oh's functional building facade which converts energy from nature to usable energy and uses it to form an environment adequate for plane growth. The facade is a collection of sensory devices that can recognise climate information such as humidity and temperature and use these information to adjust inner environment.

The purpose of artificial intelligence as a building management system is to process climatic information, and the habitable environment within the building. Performative materials applied to the facade consist of; a micro climate sensor, cellular skin panels, air and water purification filters. In this way architecture becomes a "living ecological system" with materials that can be described as performative 17.

The digital age raises the question of design intention; what is it? why is it relevant?

Design must have a purpose; even if that purpose is to have no purpose. Often this is demonstrated by a design signature that is “so author-specific as to be nearly untouchable” by others19. Naum Gabo’s work serves as a testament to the careful deliberation of an object and it’s properties.

His sketches represent “works both realised and unrealised”20. Design intention is neither chronological or linear. It is arguably the most important aspect of the design process as it creates a stable foundation for an idea to take shape.

A design intention does not necessarily need to be evident at the first conception of an idea, process etc but can be realised after the fact. In the case of Gabo’s ‘Sketch for a Kinetic Construction’ (1922), the design intent was realised through many iterations (sketches, prototyping etc) of his ideas.

Figure 13.

Construction in Space with Crystalline Center 24

This suggests that both composition and generation are essential to the design process. Traditionally composition, in the arts and architecture, has involved the master creator as central to the process of “putting things together" 21.It implies that the designer has endured a careful deliberation of the way in which the idea is composed. Generation can be defined as the propagation, “production or creation”22 of something to produce many outcomes.

These definitions are not mutually exclusive, however what differentiates generative processes from a composition is design intent.

Parametric

modelling is a generative technique that is often misunderstood and misuse. Perhaps the most useful and meaningful applications were developed under Cecil Baldmon of ARUP, who encouraged students to engage with scripting of algorithms “as a medium for research based experimental design”26.

Patrik Schumacher1and Neri Oxman postulate parametric modeling as a style 27, Parametricism “to replace Modernism”28, and plead ignorant to the true importance of a faithful design intention. The geometry generated by parametric modeling bears a striking resemblance to those crafting techniques implemented as a form of religious glorification. The Hall of Ambassadors of Alcazar, Seville, Spain is a richly ornamented room with a central dome, that evokes a sense of awe in spectators. The architecture is monumental and symbolic of the triumph of each successive ruler of the palace.

The aesthetic integrates Christian and Islamic relief techniques, Mudjer style29, and hence carries political and religious undertones.

Herzog & De Meuron Architects employed parametric modelling to achieve a similar technique to that of Alcazar in their in Messe Basel New Hall, Basel, Switzerland. of ‘slit’ geometry.

It is a visually coherent statement, comprised The appearance replicates a similar level of intricacy to that of Alcazar, but without the same religious enthusiasm. Intricacy has been justified as a “morphological state of digital design”30, but is nothing more than a ploy of deception. The “Deleuzian-cumSchumacherian Parametricism”31 dogma is devoid of meaning, and attempts to compensate for meaning by focusing on particular aesthetics rather than any valid idea.

Parametricism relies heavily on generative techniques, such as algorithmic scripting to crunch out fancy geometries. The use of parametric design as such “does not necessarily lead to any style at all, and is just an efficient way of flexibly describing geometry”32.

It seems as though contemporary architects who subscribe to this idea, believe that it is acceptable to withdraw their responsibility as a designer by employing grasshopper definitions to magically produce architecture.

Perhaps the most flawed aspect of Parametricism is trying to forge complex geometry as a design intent.

What

Baldmon of ARUP encouraged was in fact 'parametric design thinking'. He encourage this as a form of experimentation to precede any design intent, similar to that of Naum Gabo.

Parametric design thinking centers around a “logic of associative and dependency relationships between objects and their pars and whole relationship. By changing values of parameters within a schema of relationships (a parametric schema) such as geometric relationships, a multiplicity of variations can be created"351. Algorithmic thinking reveals new methods and creates new boundaries in the discipline of architecture.

There is a distinction between design ‘laziness’ and generation of geometry with a design intention. In the words of Frei Otto, " It’s a serious problem that the majority of those who work only with computers today are incapable of seeing, because to think of infinite possibilities is tremendously difficult"36.2 Random experimentation is essential to the design process across all types of media; digital or non-digital.

Physical experimentation is valid in both the digital and non-digital realm. The design process inherent in Jackson Pollock's technique reveals that retrospectivity is inherent in his technique; that a purpose can be discovered after or during the fact, but not before paint has made contact with the surface.

Senseless Drawing Bot, directly references Pollock's generative process. Although the robot is controlled by programmed devices, it is a valid contribution and extension of Pollock’s technique.

In conclusion architects should consciously seek meaning through their practice.

Generative techniques should be considered as a platform for design exploration. Random generation is a valid design approach, even if there is no initial design intention. That is to argue that testing ideas is useful but requires further refinement. Without refinement the outcome is fanciful geometries that look interesting, but are devoid of meaning.

a4. conclusion

This exercise has allowed me to explore the implications of computational design and generative techniques. I have come to the conclusion that architecture must adopt a more integrated approach than one that is limited to a suggestion of a building science.

Buckminster Fuller saw the role of architecture as an instrument for experimentation, the search for a better understanding of nature’s’ operative principles rather than reinforcing long standing academic traditions or styles. Like Fuller I believe architectural disciplines require new and motivating circumstances from which a compelling idea can take hold.

22.

I am interested in the built environment as a proposition based on free energy and climate science.

Historically, architectural design has performed the research and experimentation of building materials and their properties. The practice of architecture relies more heavily on scientific research and discoveries within other disciplines. Neri Oxman’s critique on artificial environments is an extension of scientific research into physical matter and its sensory application in architecture. This provides me with the basis for the next stage of my research.

23.

Digital modelling tends towards geometric Computational techniques and robotic fabrication provide an opportunity to consider design intent relative to material simulation, their performative potential as well as their geometric constraints.

Certain methods of design practice that have pervaded historically; such as the manual documentation of visual ideas and their personalised exchange between the counterparts of interest; are subject to evolutionary redundancy because - like any natural system - Adaptation is an instrument of the systems programme to endure and survive

Computational techniques offer the potential to make an architecture adjust to a variety of programmes throughout its life cycle to cope with external factors such as climate change and thermal efficiency. That is not to mention that engaging with these tools expands ways of thinking and the ways in which a design outcome could be reached.

My interest is to develop a design intuition as an ability to abstract an inference and to draw speculatively. This is not to predetermine a concept within the conventions of classicism followed by modernist dogma. This way I could think without obstruction about the components of form, mass and the measurement of collective thermodynamic efficiency.

description so it rarely incorporates the methods necessary for material simulation.

With the exponential advancement of computational technology , the Practice of Architecture is evolving into a self organising system of cognitive inputs; both intuitive and programmatic as the skill of Architectural Practice is learned from, but not limited to, cross disciplines such as advanced mathematics, biology and atmospheric science.

Along with digital design techniques used to generate forms, the making of Architecture is

extending beyond its prior iteration as a product of a 19th century industrial revolution, wherein we can now perceive how the interval of time can influence the dimension and representation of physical space.

Experimental investigation in technology, based both on the principles of nature and the temporality of space and substance is redefining the making of architecture. Contemporary material performance is about the capacity of architecture to become an event rather than as a collection of objects and relations.Performative materials share “reciprocal relationships between materials and their proximate contexts, acting as integral contributors to living ecological systems”2.

When conceived in this way, performative materials have a capacity to “compute”3 Thinking about Architecture in this way provides a platform for open and closed loop feedback about the atmospheric context that conditions a built form.

My intention is to explore the broader imperative of architecture and infrastructure as an instrument for environmental remediation with anthropomorphic characterisation. In particular to conceive an architecture that is "self aware... fulfilling a prescribed set of goals while also allowing for voluntary adaptation"4 and changing when influenced by stimuli.

35.

Central to the Grasshopper plug-in,

'Kanagaroo' and it's variations, is the idea of reacting to a force of gravity. Points and curves appear to pull like a string. Kangaroo is a simple way to add a dynamic layer of complexity to an otherwise static form.

Iwamoto and Scott's Vousoir Cloud employs the Kangaroo component to derive a digital simulation of inflation of a geometry. The definition for Vousior Cloud provides a sequence for the form finding process as follows:

(5) Identify anchor points (6) Apply a unary force to all vertices in the mesh. This is upwards but represents the inverse of the effect of gravity.

Following the form finding process, detailing for the subject site would have occurred, fabrication follows.

Drawing from this logic I will attempt to interrogate alternate geometric forms and derive that respond to my research.

(1) Subdivide the space using a 2D voronoi and trim with a curve representing the perimeter of the room.

(2) Scale and move down the subdiv curves to be the bottom of the vaults. Loft to the original curves to create the base surface.

(3) Use 'Brep Components' to access each individual surface and tranlate the geometry into a mesh. Join the meshes together and weld coincident vertices.

36.

(4) Edges with one 'valence' will be those around the perimeter curve and at the base of the columns (if your mesh joined and welded properly). Create a set (of unique members) from the combined end points.

selection criteria: 4 BEST OUTCOMES

My selection criteria was defined by careful consideration of geometry to derive the optimum

synthetic metaphor for the natural world. By interrogating alternate geometric studies I was able to improve the design efficiency of my iterations. I have identified the four most successful outcomes that follow my series of design aims that illustrate optimum geometric efficiency of surface and form.

Each iteration is conceived by regularising the offset panels into a continuos mesh of inverted vortex cones to optimise the gravity induced flow of liquid into individual pods. This could surmount to a design brief for a liquid purification system. Aligned with the concept of environmental remediation, the derived geometries could cater for a macro scale or micro scale design.

Hyperbody prototypes renders 10

Fabricating bespoke double curved surfaces with fabrication methods such as CNC milling or 3D printing limits the cost to benefit ratio of the end product due to inefficient material use and repetitive expenses.

Hyperbody is a project that was carried out by the Hyperbody research group at TU Delft, Netherlands in 2012. The project relies on digitally controlled robotic cutting, a novel fabrication technique otherwise known as Spatial Wire Cutting (SWC)13 . Robotic cutting is a more cost effective configuration method as it produces an instant form once cut. Hyperbody was executed by two six axis robotic arms with hot wire tools attached to their end effectors (Figure 33). The movement of the hot wire through a synthetic material, such as foam, will melt the material due to thermal release even before making contact.

Hyperbody is a conceptually successful representation of an unlimited span structure consisting of contiguous interlocking modules to achieve a scalable geometric design, with high efficiency using only one material.

elected to limit the scope of my design experimentation to the extent of perforated membrane as the structural form, without connection detail or assembly, like in the original Hyperbody.

I had little control over the control points in the base geometry.

This could be overcome by generating a geometry based soley in the grasshopper environment rather than referencing points in from Rhino.

Hyperbody is premised on the idea of a hyper elastic surface to achieve unlimited arch span between any given two points, and is repeated to improve freestanding stability. I want to continue to explore Kangaroo as a tool for form finding through inflation and for measuring structural integrity like in Hyperbody.

The technique I explored was based on controlling a robotic arm to cut a Series of paths derived

from interstial surfaces in a form created by employing the Iwamotto and Scott technique I explored in B.3. A hexagonal grid was created, each hexagonal cell scaled and moved in the Z axis direction and corresponding 'cell' curves lofted together. This technique involved attaching a block of foam to the end effector of the robot and controlling the robotic arm to move through a series of positions through a fixed hot wire.

This geometry was derived from circles manipulated using the graph mapper component, sine sum-

mation, to produce osculating planar closed curves. Frames were then generated at the mid point of the lofted surface. In the first iteration the TCP attachment was placed in the middle of the foam block and the motion of the TCP rotated out of axial reach. To resolve the issue faced in the previous iteration, the size of foam block was increased and frames were moved away from the TCP to another point on the foam block. The axial rotation of the sixth joint of the robot was acting erratically in the previous iteration. I decided to lower the frame resolution. The outcome was a smother axial rotation of the joint.

When I commenced the ABB Robot, the robot moved the foam to the starting frame

and in doing so moved the foam piece attached to the TCP through the hot wire.

This lead to a damaged piece of foam before the robot performed the cut of my field geometry. Since I set the speed of the robot to a low speed, v200, it was possible to increase the heat of the hot wire. This was made possible by turning the voltage up on the circuit board, and making the distance of the conducting clips relative to the foam block shorter. The path geometry is derived from my Algorithmic research on fields.

In the following iterations I tried to achieved angled cuts by rotating the curve in series. In this iteration I started the rotation after the entry path in the 11th frame. Analysing the resulting foam, the entry path and foam were not calibrated correctly and resulted in only a part of the foam being cut by the robotic arm. In the next iteration I simplified the geometry to avoid collision of the robot, and explore rotation.

After the geometry was simplified there were no further problems in the simulation. Analysing the resulting foam, I had increased the heat of the wire and the speed of the cut. This achieved a smoother cut.

Material EXPERIMENTATION : plaster casting

Figure 52. Foam template

I

conducted a preliminary plaster cast in order to study the material properties of plaster. I chose to use two pieces of symmetrical form work, the shape created using a MDF board template.

During the mixing process of the plaster and water, given the lack of experience and prior research into the process of mixing plaster, the mixture ratio of water to plaster was incorrect and mixed for a time period longer than the curing time. I soon learnt that plaster has a fairly quick setting time, especially when too little water is added to the mixture.

The result was a clumpy and hardened mixture when poured into the form work. In order to fit the mixture into the form work the mixture was compressed into the space with striking force.

62.

Figure 53. Casting process

Figure 54. Resulting plaster cast

Given the experimental nature of this cast, the

process and the outcome itself was to become precedent for my future casts. The outcome was a coarse, rough and did not follow the shape of the mold. The model displayed an interesting quality; air gap cavities which were the result of pouring the mixture after the setting time. This was not an ideal result, however this look could be deployed in further explorations as an intentional aesthetic.

Figure 55. Resulting plaster cast 63.

b5. plaster casting

Foam form work was cut into three parts with a

hand operated orthogonal Hot Wire Cutter in order to remove foam from the centre. Plaster of Paris was sifted to achieve smooth granules. Extra water was used to achieve a softer plaster. Plaster mixture dried for more than 10 days. Imperfect surfaces and denting is the result of applying a thick grease with a coarse brush. Grease stuck to dried plaster leaving a slimy residue on the surface. This excess grease was wiped off the cast surfaces with wet wipes.

The plaster casts were smoothed by carefully carving off large dented pieces with a Stanley knife. Finally wet sand paper was applied in light strokes to create a more even and buffed surface.

Surface defects were prevalent despite efforts to treat the suface. Perhaps some additional plaster could have been rubbed into the surface with ones fingers, allowed to dry and be sanded back for a smoother finish.

Since the plaster was not poured evenly in foam form work, the three cast pieces did not fit together as a continuous form when aligned.

Thin edges and resulting chipping from low Figure 56. Resulting plaster casts slenderness ratio at edges of cast pieces.

Although

the resulting cast pieces were not completely seamless, the outcomes were pleasing. The premise behind this casts the 'act of twisting' resonates with my research into Material Performance. Plaster represents a static, rigid and fixed material, not easily shaped once hardened.

This exploration was the impetus for my further research into non conforming and malleable materials.

Silicon casting Equal parts of pink and white mixture were

measured and mixed together. This material conventionally works well as a flat form work with a central area open for a material to be cast into. However it also performs well as a coating agent for form work if enough layers are applied. This was further explored in B.6 and Part C.

group DESIGN vision If anthropogenic activities such as urbanisation and changes in atmospheric conditions continue to shift the balance of planetary conditions, the end of the world as we know it could be imminent.

The ambition of our design concept is inherent in it's micro scale interplay. The outdoor laboratory space will operate as a performative structure, catering to three purposes. Firstly, the design itself will function to revitalise the immediate ecosystem. Secondly, it will be a place where experts from the field of science, perhaps biology and geochemistry, will interact with the creek as a sampling check point. Visitors will be able to volunteer to assist these experts and engage with the site and it's natural qualities.

Furthermore, the outdoor experimental space will encourage certain members of the community to take ownership of the site. The structure itself will symbolise the importance of the preservation of micro scale ecosystems.

B.7 learning objectives and outcomes

Spatial Wire Cutting is controlled by the robot's coordinated movement and is constantly altered

throughout the process. Hence, this technique allows to significantly expand the set of possible hot wire cutting geometries to certain double curved surface, in particular sweep surfaces, which cam ne defined by the motion of a changing profile curve along two trajectory curves. Rather than focussing on performative materials, we should be designing performative structures for specific micro-climates.

74.

75.

B.8 APPENDIX-hot wire cutting EXPERIMENTS I conducted a series of preliminary tests on small pieces of foam prior to commencing hot wire tests employing the robotic arm.

I had a design laser cut twice on MDF. I attached each MDF piece to a foam block, attaching each on opposite sides. I used this 'template' to achieve a uniform profile. This idea is similar to the "path method" explored in B.4 to generate frames for the robot to move through. However, one of the main aspects that differentiates robotic cutting from manual cutting is the level of precision and accuracy achievable in angular cuts.

MDF Template

I further explored this concept when engaging with the robot in B.4. I experimented with how a two dimensional path could be manipulated by rotating the position of frames on the path curve.

Draping effect

When casting I experimented with casting both the positive and negative forms of cut foam. The negative provides a sturdy form work that could easily be placed into a form work box. I achieved this 'Square cut' while working with the orthogonal hand cutting machine, where the angle of the wire is adjustable.

Square cut

The positive requires glue or other fixing agents to secure the loose element in place. These precautions are taken to ensure that the foam does not float away during the curing stage.

Negative Form 76.

Positive Form

This experiment shows the effect of a loose wire.

I employed a soft in and out motion to achieve an effect that resembles the soft flow or draping of a curtain.

Linear texture

When utilising a loose wire soft curves could be achieved. This technique could be further explored using robotic hot wire cutting. The lack of control could produce interesting and unpredictable outcomes.

Soft angled

Loose hot wire; scalloping

Jaggered cut

In conclusion, hand operated foam hot wire cutting is limited. One may achieve straight and angular cuts when operating the orthongonal cutting machine that includes measuring tools. When trying to achieve a curved surface it is difficult to control, unless one is using a template. However to achieve a variation in angle requires rigorous preparation, and can not be easily reversed when working with physical materials. These kinds of variables are easily changed and controlled in a GrassHopper defintion, allowing for faster prototyping.

Prior to the commencement of the design phase, research was conducted on what sorts of contaminants affect water quality. We have identified water quality as the most necessary variable of the site that required immediate action according to our findings from the preliminary site analysis. Having been asked to design for a brief that caters to 'vertical transportation' we have framed this in the context of existing ecological systems on Merri Creek. Water is the most important element that supports all life forms. By improving the water quality we could re mediate many more issues occurring. Thus our design intent is not only to remediate the water quality but to also derive the optimum synthetic metaphor for the natural world, surmounting to our design brief for a liquid purification system.

In consultation with two experts in the field of bio remediation we were able to deduce a sound body of research to inform our final design. Our first consultant, Dr Hong Phuc Vu is an expert in Geochemistry who informed us of the array of contaminants in waterways, the cause of pollution in waterways. We concluded that the aquatic ecosystem is severely affected by anthropogenic activity from urbanization, industrialization, agriculture and other alterations. All of these activities increase nutrient inputs into water bodies, especially nitrogen and phosphorus3 . We discussed possible synthetic treatments. One such option of utilising prevalent and naturally occuring microbes, such as algae. Hong discussed the idea of maximising surface area for microbial growth, and utilising them to absorb water contaminants.

Dr Augustine Doronila, Senior Analyst at the University of Melbourne School of Chemistry, directed our research towards restoring ecology. In particular advised us to research the potential of Wetlands to reverse effects of toxic water contamination through a natural plant root filtration system; giving it the ability to restore water quality. Aligned with this advice is the project at the Botanical Gardens in Melbourne, Guilfoyle's Volcano, a series of floating wetland system where roots float freely under circular floatation devices acting as synthetic filters.

Our final design attempts to integrate both methods of purification, microbes and wetland plants, as a micro structure in order to be easily replaceable and interchanged depending on local circumstances.

proposal

CATALYTIC CHAMBERS is a proposition for a staged low tech impact installation to remediate

the length of the Merri Creek that flows north of Melbourne. It is a new speculative architectural project designed for the Merri Creek in Clifton Hill, however has far reaching applications for open/ closed waterways, public health and cities around the world. Believing in the potential of architecture to catalyse change, CATALYTIC CHAMBERS addresses the future relationship of architecture and science as a real time feed back loop.

CATALYTIC CHAMBERS consists of water purification in three elevated algae ponds acting as a kinetic filtering installation and as a working metaphor for the natural world. By introducing an artificial micro climate, CATALYTIC CHAMBERS creates a local variation that can restore and improve an imbalance to the riverâ&#x20AC;&#x2122;s bio-organic diversity. It is relies on automated hydrology and the natural processes of microbes to absorb contaminants in water.

An uninterrupted conduct, the reticulation of water, and microbial processes that occur in the chamber act to absorb contaminants found detected the flow. In doing so concentration of contaminants is diluted.

By sequencing the elevated algae ponds as a series of catalytic chambers, arrayed in three stages, the suspended liquid chambers return water to a purified state in the form of a droplet release.

Each chamber is an emulsified membrane suspended within a network of pipes and held in place by a flexible ring frame. Each ring of the installation can be accessed separately by a pulley system that will lower the structure to an accessible point on the river bank. Finally, the structure is lowered into space, like a curtain, to disclose an event in void space.

The first iteration of design concept involved designing pipes that were textured for microbial growth. Although

we did not go ahead with this idea for the total design form, these experiments proved useful none the less for the evolution of a pipe into an enclosed chamber, as texture remained integral to the design concept. If we were to attach a drill bit to the end of the robot, and carve out a pattern, the third iteration could be achieved. However, due to restrictions this was not possible and we went ahead with the original hot wire method for all areas of fabrication.

It was determined that for optimal microbial growth the water rate needs to be slowed down and this is the reason we moved away from detailing a pipe to isolated and catalysing chambers.

113.

The prototypes generated are not ruled surfaces. This was challenging when we reached the fabrication stage. We chose iteration two as it is a maximised surface area for optimal microbial growth.

proto type outcomes

"The [e]ssence of architectural creation [lies] in... that interior and exterior of the emerging work are to be seen as something homgenous, as though a transparent mass, mobile under the fingers of the creator" 6

What I liked most about using resin and plaster in my prototypes is the interior and

exterior quality that resemble x-ray vision. During the casting phase it was most useful to cast a dollop of plaster to block off any openings that the resin could leak into. However these casts still required surface treatments despite the fact that they were cast in a smooth silicon coated form work. I sanded the plaster with high grade wet sand paper.

Some of the casts, 6., were defected and cracked due to a high slenderness ratio for the plaster or because casts were conducted in layers which dried without properly attaching, resulting in separate pieces that had to be glued together.

Robotic Fabrication opens up the profound

possibility of creating strong and meaningful feedbacks between matter and making. It allows for the freedom to create your own tool based on the project "as opposed to creating a project based on the most recent CNC purchase"7 Robotic hot wire cutting is also a tool of mass production, a rapid prototyping tool, only once the digital definition is organised a lengthy and enduring process.

Given the nature of this studio the robots became the single dominant fabrication tool in producing physical outcomes. I wanted to push my experiment further and venture beyond using the robot as a custom form generating tool to produce a performing model that is true to the ecological functions as a living, breathing, tool for water purification.

Formulating a brief was integral to the process of utlising the robots as a fabrication tool. Prior to the commencement of the group design there was much deliberation within the group to decide on where our design would sit within the spectrum of computational tools. We decided to use the robot as a way to mass produce a bespoke form work for our chamber. Using the robot allowed us freedom in design form and catering to our vertical transportation/water ecology brief.

132.

Given the feedback from our final presentation it seems that perhaps were consumed with learning how to operate the robots that other aspects of the design were neglected.

The Grasshopper interface offers many more powerful capabilities. Given the flexible platform it offers it can be extended through plug ins and utilised to parametrically map out points of interest. I imagine our design could move in this direction. By setting a series of conditions and the objects program grows until the conditions are met8.

This would be to employ permutations as a generating tool and choosing an option that could be justified in terms of the brief criteria.

Permutations use important location points (nodes) and connections (links) to deduce circulation pathways. A major confinement of our design was the localised site. Catalytic Chambers is a concept that could only be effective if many systems are spread over a large distance. Since each site has a different set of conditions, the loaction, assemblege and form of the design will alter between sites and could be deduced using the mentioned permutations design technique on a parametric platform. In this sense this validates "programming is the vehicle for obtaining new knowledge, for seeing things that can not be seen"9

N ineteenth and twentieth century urbanisation poorly planned infrastruc-

ture and waste management strategies remain. Melbourne is no exception.

CATALYTIC CHAMBERS is an attempt at purification infrastructure for public and private domains that purifies the quality of Waterways.

C ATALYTIC CHAMBERS is a proposition for a staged low tech impact installation to remediate the length of the Merri Creek.

Itâ&#x20AC;&#x2122;s modular structure is not only specific to the Merri Creek site but could be implemented in other contaminated open or closed waterways.

C ATALYTIC CHAMBERS consists of water purification in three elevated

algae ponds acting as kinetic filtering installation and as a working metaphor for the natural world.

By introducing an artificial micro climate, CATALYTIC CHAMBERS creates a local variation that can restore and improve an imbalance to the riverâ&#x20AC;&#x2122;s bio-organic diversity.

Each chamber is an emulsified membrane suspended within a network of pipes and held in place by a flexible ring frame. Each ring of the installation can be accessed separately by a pulley system that will lower the structure to an accessible point on the river bank.

It is relies on automated hydrology and the natural processes of microbes to absorb contaminants in water. Water is pumped relying on the natural flow rate into the circulated.

An uninterrupted conduct, the reticulation of water, and microbial processes that occur in the chamber act to absorb contaminants found detected the flow. In doing so concentration of contaminants is diluted.

By sequencing the elevated algae ponds as a series of catalytic chambers, arrayed in three stages, to return water to a in a purified state and discharged as droplets. The suspended liquid chambers to return water to a purified state in the form of a droplet release.

This technique was digitally replicated using the ‘“jitter” component in Grasshopper for our final design.

TEXTURE EXPERIMENTS

Given the limitations of the robotic arm size we were limited to the size of form work that we could produce at a large scale. In order to cast our chamber design the following form work strategy was devised.

Government agencies will provide funding for the construction and cost of the Merri Creek CATALYTIC CHAMBERS. The revitalisation project which also include various researchers from the civil service. In addition, local community is also engaged through programs such as the waterwatch which is a programme launch in conjunction with the Australian government to help sustain and improve Merri Creek.

However, researchers and experts may not be on site frequently, hence the local community are the one that will interact with the site most of the time.

2. RING STRUCTURE

E ach chamber is an emulsified membrane suspended within

a network of pipes and held in place by a flexible ring frame.

Each ring of the installation can be accessed separately by a pulley system that will lower the structure to an accessible point on the river bank. From there the It is relies on automated hydrology and the natural processes of microbes to absorb contaminants in water. Water is pumped relying on the natural flow rate into the circulated.

3. TURBINE

Plant roots provide a very large surface area for nutrients to be absorbed.

INPUT

A sticky biofilm complex mass of micro-organiss covering the roots help trap the particles and absorbs nutrients from the water

OUTPUT

Textured interior provides an increased surface area providing greater chances for cultivated microbial growth.

T he chambers are easily replaceable with two parts prefabricated form (part A - plant sack and part B - chambers) that are arrayed within each ring.

The rigid structure is both the water transportation mechanism and the structure to suspend the pods.

Accessing the structure and the task of replacing the pods is put at ease of a system of pulleys which the rings are attached to.

The structureâ&#x20AC;&#x2122;s presence on the site is a celebration over the event of inputting and outputting water, raising the public concern of environmental issues.
