INTRODUCTION

“

I seek creative freedom, explore new possibilities and innovation in my second coming.

rt & Architecture has always been my passion. After working in engineering and computing for a while I decided to pursue my passion knowing that this would be my last opportunity to do so at my age.

I brought with me my maturity, established work ethics, experience in engineering and computing to this endeavour. Strong discipline and time management with razor sharp focus in my intention had helped me to explore architecture with vigour and enthusiasm. My philosophy in architecture are to be critical and observant to the surrounding that gives us our inspiration, material and wisdom. Simplicity is paramount. Ornamentation is excess. Structural clarity is the holy grail.

In view of this balance, I have taken the initiative to self-learn major design tools such as Adobe Creative Suite (Photoshop, Illustrator and InDesign) as well as digital painting tools and software i.e. Corel Painter and Wacom digital tablet. As I also enjoys photography in my free time, I am able to include this as part of my overall creative offerings. In addition, I am improving progressively in major 3D modeling and rendering tools such as Rhino 5, Autodesk Revit, 3DS Max, Maya and Vray/Keyshot/Maxwell for rendering. I am also exploring visual programming knowledge through Grasshopper, Processing 2 and Dynamo(+Vasari) however it’s a new frontier to me ,I look forward to finding opportunities to use some of these tools not just for form finding, performance analysis and generative art.

Coming from the computing field, I understand the potential and possibilities of digital and generative design. I see design software as tool to enable exploration. Equally important for architecture students, manual drawing skills allows more expressive work to rather sterile computer generated images. A good balance of computer work couple with expressive drawings , in my opinion, will be able to explain the technical aspects of my design but also the emotive component which can relate better at the human level.

Digital and parametric design in architecture provides new and exciting area which I have vested interest in. In my opinion it’s the new style or ‘ism’ in architecture which is becoming more and more prevalent style post post-modernism. Computation work in architecture further extend the capability of contemporary design to be more responsive to its context and environment thus contribute toward the overall sustainability of the planet.

Design Futuring : A manifesto towards a sustainable future.

ur contemporary culture and how we design for our living is heading us towards destruction. Tony Fry in his book “Design Futuring : Sustainability, ethics and new practice” pose us, the design community, with a challenge; to change our mindset and our design values to support sustainable future [21]. As part of the larger design community, Fry proposed the following broad ideas for our ‘design futuring’ : 1. Design is an agent of change and the community must be empowered to lead the transformation towards sustainability. [22] 2. Design must not hide behind the triviality of appearance and ‘style’ [23] 3. Sustainable design must depend on combination of nature and man-made ecology and not each in isolation.

5. We must support, participate and influence creation of design intelligence through design research and critical designs [25]. In view of the above, 2 case studies attached are precedents that display the capability and techniques gained through design intelligence. In Patrik Schumacher’s concept of architecture as an autopoietic system of communication[26], these examples form cycle of new ideas which becomes the basis of critiques and provide further improvements to the existing or generate new ideas which is necessary for architecture discourse. The vitality of architecture as a field depends on its community to continuously produce critical designs [27] as ‘artefacts’ [28] and means of us to communicate to the wider public (outside of the autopoietic system of architecture) while enriching internally the architectural discourse.

4. We must foster design intelligence that have the ability to analyze forms and its context and make important decisions as part of the design process to improve futuring potential. [24]

case study 1 PabellĂłn de la Sed The Thirst Pavilion, the International Water Expo Zaragoza 2008, Zaragoza, Spain

his pavilion was built for 2008 Expo Zaragoza in Spain to promote water conservation and sustainability. It was conceptualised from the molecular structure of salt and strongly represented by the form as well as its conceptual implementation of the salt mountain. The architects, Cloud9 and Enric Ruiz Geli were inspired by the water droplets on top of the salt mountain represented by the transparent bubbles on the structure [29]. The thematic approach of sustainable design not only reflected in the form but also its functions, construction material, process and technology. The structure was realized using prefabricated steel components and assembled using common construction techniques and technology [29]. This was intended to be easily assembled and disassembled after completion of the expo. The sustainability theme is further extended to its use of material. The external geotextile skin, pneumatic ETFE panels are recyclable. Additionally ETFE has various advantages in comparison to other common building material such as glass. Its super lightweight, controllable light transmission qualities and has good insulation properties. [30]

the Beijing National Aquatic Centre at a larger and permanent scale. [31] I have chosen this example to illustrate few observable trends in contemporary modern architecture. The field of architecture has progressed alongside computer technology as means of form finding and no longer isolated as tools for drafting and modelling. Computation works in architecture allows for performance analysis and optimised form finding. New research and leading edge technology allows design to response to its surrounding context. The outcome of such research and new technology brings about a new â&#x20AC;&#x2DC;ismâ&#x20AC;&#x2122; in post-modern architecture ; Performalism = Form + Performance. [32]

The convergences of engineering, architectural sciences , mathematics and art have generated new building style that are dynamic as well as environmentally responsive.

The Thirst Pavilion, is one of many new breed of architecture testing and Figure 1 : Salt watering system [3] challenging the status quo by offering unique design that is responsive to its environment, implementing a The ETFE panels coupled with brine total sustainable solution through building material, watering system and a cooling system for the airconstruction method and reduction of energy usage. filled pneumatic panels allows the structure to offset Innovative design like this provide critical design the heat gains from visitors and equipment [10]. example for the broader architecture discourse that This improved the cost of operating the building and continues to improve itself moving forward. more sustainable than the traditional air conditioning system.

PERFORMALISM Pritzker Architecture Prize winner Thom Mayne introduced the idea of performalism as separating the exterior skin of a building to response to the climate (form follow environment) [33] while the interior focuses on program/function. However, Neuman and Grobman [34] proposes the idea of computer based architecture that changes the idea of function to performance. Through computation, form in performative architecture is an outcome of performance analysis.

idra tree, native to Qatar, a holy symbol to Islam and represent knowledge of the divine was the concept behind this entrance structure to the convention centre. The architect, Arata Isozaki, uses the structural optimisation approach in arriving to the optimal form desired, mimicking the tree for the form desired. Optimisation method known as extended evolutionary structural optimimization (EESO) [35] allows for sets of criteria i.e. material, loading profile and sites to compute the best and most optimal performing shape with least amount of material use. The optimization algorithm using the finite-element analysis to progressively remove unnecessary material and add material to support loading at load bearing points in repetitive computation cycle. Similar automated form finding and optimization algorithms are now being used in larger architecture firms such as SOM

Through its origin from the engineering field, architects and structural engineers are now collaboratively workimng together in form finding. Collaboration between these groups is critical to jointly define parametric constraints and performative goals of the projects. I have chosen this example to highlight new collaborative workflow in the quest for new design and form in architecture. In this example, architecture and engineering had to come together to come up with a nature inspired design out of an engineering based analysis tools. Similar collaborations in the fields of mathematics and arts for examples had came out with interesting solutions to design problems .

Figure 18 Major phases in architectural deisgn process [21]

he pervasiveness and availability of computing system and computing power has begun making significant inroad in all aspect of human civilization including design as many feared or anticipated. Design process consists of 4 interrelated phases [36] , see Fig. 18 by which all have been completely automated or highly dependent on computing. The question is, if what Kalay [37] is saying that design is the symbol of human intelligence, has computers taken over our unique characteristic as intelligent being and we are succumb to the power of computation work in all of our design process and form finding in architecture? Computerisation to Computation From its early appearance, the increase of computing power had lead to gradual shifting our traditional design process particularly in the communcation phase. 2D drawings and drafting are now completely “computerised”. However computation is beginning to play a significant role in problem solving phase with advancement in knowledge system (BIM) and scripting tools for environmental and performance analysis. To our advantage, computation work had taken over the processing of vast amount of data and converting them into meaningful analysis that can influence architectural design process. This analysis allows for further explorative study for new ideas and provide the basis in the next stage of the design cycle i.e. the solution synthesis[37]. As solution synthesis is an intuitive process of human intrinsic ability, computation work is now able to assist in expanding designer’s capability to solve even more complex problems by giving a wider spectrum of perspective for more informed decision making and creative insights [38].

Form finding tools in computation work can greatly assist us in exploring new forms and design similar to the traditional approach of form finding such as plasticine , paper cuts etc. This point is where we can decide whether we will succumb to machine to decide our design or use the “suggestive” forms as informed creative “insights” that we can develop along with our creative expression. Performance Oriented Design As part of the strive for “Design Futuring” where we must consider our built environment in sustainable fashion, this is where the role of computation becomes clearer. Computation work had led to new area in architecture called performalism (Performance and form design) or performative architecture. Performance-oriented design uses the vast computation power and scripting tools to create customise analysis for optimal solution that is climate responsive and while offering aesthetic innovation. New collaborative workflow Computation works have also redefine how architects works. New breed of architects with programming and scripting skills not only generate 3D models but also provide existing archtectural practice new approach in design exploration, performance simulation as well as fabrication. Schumarcher’s vision of autopoietic system of architecture [39] described the building of architecture’s design intelligence through external inputs and internal knowledge accumulation. These external inputs are multidiciplinary participations in research and design from different field of studies such as engineering, biology, arts and mathematics offering new collaborative culture in computation work. For example,

COMPUTATION tools such as traditional FEM (Finite element method) finding its way into architectural design process. Originating from the structural engineering field it had cross-over as an architectural form-finding tool aswell. This cross-over introduces new collaborative approach between architecture and other fields to fully utilised innovations offert by the counterparts. New geometries, new opportunites Generative processes and techniques from topological, non-Euclidean geometric spaces, parametric design and morphogenesis [40] had introduced new shapes and forms never before achievable through traditional design process. The introduction of free-form nonEuclidean geometries through NURBS (non-uniform B-spline) method supersede the traditional forms of point ,lines and planes.The expanded geometric vocabulary gave architects more flexibility to express their design. Consequently, these new shapes had also stimulated new material culture[41] and introduced the integrated digital fabrication technique which is now redefining the architectural design and material production simultaneously. Digital Fabrication, New efficiency

offers efficiency and reduction of material wastage. The impact of this offering pose an interesting social and economic dilemmas which is ongoing debate on the future of architecture and building industry. Digital shift in architecture Computation work in architectural design process marked a new shift in Architectural expression similar to the preceding shift to Modernism from classical architecture. Introduction of new building material and technology during the Industrial revolution introduced the Art Nouveau style with its organic and free forms from the ideas of Viollet Le-duc, Victor Guimar and Antoni Gaudi. Similar shift from modernism to post-modenism was observed from 1920s onwards [45]. These precedents suggest parallel indicators to the profound and transformative shift that we are experiencing at the moment. It’s to suggest that it’s an inevitable change for architecture with the digital design process, the new material culture coupled with the confronting question of sustainability of our built environment. These factors have accelerated the push towards design computation. As a result, design computation can now claims its rightful role in the architectural design process.

With the whole workflow from designing to “making” (fabrication) is now completely within the digital realm, it is also making significant impact on the production/ construction process[42]. This convergence, representation and production, will significantly change the building industry in the very near future once the current technology can be scaled up to practical industrial use.In line with the idea of sustainable build environment, digital fabrication

igrating Formations illustrates the convergence of the designing process with the “making” process where the computation work fed directly into the robotic manufacturing techniques [46]. It provides an insight of what is possible in future for architectural constructions. The convergence of design and the making process through the robotic manufacturing technique removes the traditional construction technique i.e. formwork etc. while integrating the structure and the skin into a single form. This is groundbreaking as digital fabrication reduces material and labor waste by eliminating the construction material and labour required for constructing the formwork. This idea ties back to the whole concept of design futuring and sustainable future. The design also challenges the traditional concept of a wall by introducing the elements of “formal, spatial and opacity”[46] into a single form of a wall. Computation work allows for the designers to control the variations (formal, spatial and opacity) of each sides of the wall to achieve their design goals. Although the design, in my opinion, focuses only on aesthetic and sensory affects, it’s however offers possibilities in real world applications with the manufacturing techniques and integrated wall system.

The evolution of forms occurs through changes in development Sean B. Caroll

S_Canopy is a speculative design meant to instigate critique and explore new method of form finding. Exploring the morphogenetic concept from the Biologist Sean B. Caroll’s “Body Part” where he argues that in a cell development, a “gene toolkit” generate an algorithm for the cell to create different body parts from the same “instructions” [47]. Variations in the design outcomes are driven by this parametric dependencies set through the specifications of the local condition and materiality. The different forms generated are meant to challenge the conventional definition of architectural elements such as columns,

shade/roof and seating/counters. Through the “genetoolkit” idea, different forms can be explored using the core algorithm. Parametric modeling also allowed exploration of the performative potentials of the design. Varying the local conditions will result in an optimised shading qualities of the roof.

01 Figure 10 Gene toolkit script varying parameters to local environment and materiality[12]

This precedent illustrate the role of computation work, which allows for experimental exploration of new expressions in architectural forms through morphogenetic parallel. Intrinsic to the exploration is the analysis of performative potentialities as part of form finding. Together they display great potential of computation work in architectural disgn process. 15

generation

omposition versus generation in an ongoing debate with the advent of parametric architecture which introduces the concept of iterative generation. Composition according to Jacques Lucan refers to the formative architectural ideas[48] during the process of designing prior to the emergence of the final work. Lucan further elaborated, ‘composition is antecedent to “styles”, or, to put it another way … a given composition can be dressed in several different “styles”.’ [48]

In essence, composition is the inputs while the style is the outcome. Generative (and generation as the outcome) in contrast is purely a digital process specifically the process in parametric modeling. Lee, Gu and Williams refer generative as the exploratory process in parametric design where variations (generation) are ‘generated’ by changing design parameters, ‘topological’ relationship and algorithmic rules sets in the design script. They further claimed that this process is a creative process [49] thus putting it at the same analogy to composition. Generation in digital design process 16

allows for designers/architects to explore architectural spaces by varying parameters that relate to placement of architectural elements, configuration and their relationships [50]. These variations are coded through algorithms into scripts and computer programs. With increasing processing power of computers, architects can solve more complex design problems using parametric modelling. The most apparent benefit of use of generative approach in architectural design process is tied to the word “parameter” itself. The ability to set parameters that are changeable greatly assist designers to change design on the fly and view the outcome on the screen. In turn, decision-making can be more precise and prompt from analysis generated from computation work. Efficiency is the by product of this approach. The biggest shortcoming of generative design is the programming skills required to code the script and algorithm in visual programming software such as Grasshopper (in Revit), Dynamo (in Vasari) or Processing, to name a few. Peters refers these group as new breed of designers that he classify as

computational designers [50] . They have skills to understand design requirements and translate them into script/program for design exploration. The computational designers would be well verse in algorithmic thinking to solve design problems as they will take on the “interpretive role to understand the result of the generating code” [50] . The contention here is that does the algorithmic thinking to ‘generate’ design is as ‘creative’ as composition in the traditional design process? Can architects be both designers and programmers? Terzidis argues that the role of architect has now change from ‘architecture programming’ i.e. creating and planning of space to ‘programming architecture’ which reflect the shift from composition to generation.

a Familia Segrada is an architectural artefact as well as an ongoing development and could be finished some time in the first third of the 21st century. Antoni Gaudi’s innovative form finding method has been the basis of form fining study. With the advent of parametric design it has been precedent of choice in the field. Inspired by rock formations of the Spanish mountains [52], Gaudi was able to workout the complex three dimensional forms of his design through mathematics some 133 years before design computation even exist. To continue Gaudi’s legacy, Mark Burry, the executive architect used parametric modeling technique to intrepret Gaudi’s design intentions and “reverse engineer” his original model to complete the design development and construction of the church [53]. To generate the unique hyperboloid surfaces, parametric modelling was also used in production of the building material (stones)through an off site pre fabrication using computer driven milling machinery [54].

As the construction is funded through donation, the design development is part of a joint multi-diciplinary research and design collaboration involving “parametric model sharing” [55]. It is a collaboration of dispersed design and research teams worked on the same parametric model to come up with an optimised design. This highlights the new collaborative workflow as an outcome from computation work that promote efficiency and working culture. What I found interesting with this project is that the apparent example between composition in traditional architectural design process versus the contemporary digital design counterpart, generation. Antoni Gaudi’s composition of Segrada Familia was in response to the wave of Art Nouveau style in Spain called Mordenisme. His composition uses many geometrical chosen for their formal, structural, acoustical and constructibility. This is prior to any form of computation technology. In constrast the current work inspired by Gaudi’s composition are done through generation from the computation work. BACKGROUND Computer generated model of the nave of Familia Sagrada [11] 17

he FabPod project was a response to the challenge of designing an enclosed meeting area within the working environment on level 9 in the new Design Hub at RMIT.

Inspired from the anecdotal observations of the interior space of Gaudi’s Familia Segrada Church in Barcelona, Spain, a multi-disciplinary team researched the sound diffusing properties of hyperbolic surfaces [56] to come up with an interesting design that resolved the problem of creating a small enclosed area in an open planned setting. This case study highlights the opportunity of computation work specifically in the area of scripting culture that allows generation of performative surfaces to resolve design problem from environmental influence. While the area of acoustic reverberation and sound absorption is well studied and implemented in concert halls and quiet rooms, sound/noise diffusion is a new area of research [57]. Scripting allows for versatility in the generative design while the team search for optimal design in the area of material performance, prototyping and production of the final structure. Each area of studies will fed their results into the overall core algorithm producing a sample design then further optimised in the next iterative generative cycle until all design specifications are met [58]. As the “making” process is also integrated, each cycle will produce a physical prototype. This prototype will undergo testing and the results are fed back into the script for further optimisation. This approach opens up real world application where design can really be tested for real world scenario. Such opportunity not only revolutionise the architectural design process but also impact the material culture and building industry. Sustainable building material that can be pre-fabricated off site while accurate material cost will reduce wastage. These are some of the many benefits propagated through the workflow induced from the scripting approach. 18

_Wall is an outcome of the performative analysis of material and geometry to produce a unique wall design and tiling system. The design itself refers to the characteristics of human skin; the bulges, crevices, folds and cleavages. This project illustrate the self-organization properties of an elastic material under force i.e. the constraint system [59]. Combination of material analysis through physical material experimentations and scripting of the constraint system were used to produce such dramatic effect.

Figure 17 : Transformation of image into constraint points through the use of custom rhinoscript[20]

An approximation of the surface was done through scripting of a sine waveform and the constraint points. The actual self-organization property of the liquid plaster before it sets and material property of the elastic nylon form work as the constraint system were studied through physical experimentation.

This is an interesting examples that highlights gap between what the digital modeling can represent, from the result of the physical experimentation actually produced. It also offers an interesting challenge to me to find novel ways in mimicking nature in my quest to solve problem in the site, Merri Creek.

conclusion

rchitecture is in a verge of transformation. It’s at a point where the role of architecture is in question. Our built environment and the path we take as an architect at the present trajectory will lead us to unsustainable future. A new attitude needs to be adopted that require us as the builder of the future built environment to be sustainable in our design. The design futuring aims to build new design intelligence and empower us to become the agent of change. This mind-set will instill the idea of using our design as a means to push sustainability. In doing so, our design must take advantage of computing not just for automation (computerisation) in our design workflow. We have in our disposal the computation work that can augment our creative intelligence to design our built environment to be sustainable and climate responsive while providing efficient use of space and function. Architecture is also in the verge of transformation of style. A style that is driven by new geometries and computational techniques. Parallel to the shift from classical to modernism, digital design is transforming the way we express our “modernity”. We must not however become complacent and let computation work to express itself though our design. We must instead embrace computation

work as means to find an expressive form that will perform to function and its environment. Algorithmic thinking, parametric modelling, parametricism and generative design are among many developing approaches that we can use to express our design. Architecture as an autopoietic system as suggested by Schumacher will thrives with the new shift to digital design. Our speculative and built architectural works will instigate critiques and become ‘architectural artefacts’ . In turn they will build upon overall architectural design intelligence. The case studies in this documents are examples of the accumulation of architectural design intelligence. To contribute as part of the design futuring and propose a design for critique, I would like to introduce the approach of performative and parametric modeling to resolve one of the Merri Creek environmental problem caused by manmade infrastructure. Using performative design approach, I intend to balance the design aesthetics to the environmental response. The existing built environment has already affected the natural habitat for wild life as well as its human counterpart. The design intention is to lessen the impact of man made infrastructure on its natural environment while offering a biomimicry driven design that’s pleasing to the site users.

learning outcomes

he readings introduces a critical concept of Design Futuring which I found very relevant in building my architectural philosophy and influence my design expression. The readings also have given me the distinction between the various terms such as algorithmic thinking, parametric modelling and generative design. I have developed my own perspective on the argument of the role of digital design and computation work in architecture through the selection of case studies .

It’s also a confronting experience with the idea of developing forms using scripting without knowing the final form. This is different to traditional design process which I would start by sketching ideas and improving my ideas with full view of what I wanted to design. With clearer view of the tasks ahead, I am quite keen to explore this new way of design thinking.

The class discussions so far was also instrumental in forming my own opinion about the subject matter. I was able to see through other people’s eyes what is their stand on this matter . As a result I can formulate my arguments better while be inclusive of others ideas and opinion . This initial experience through the readings and algorithmic sketching solidify my interest in design computation and gave me the enthusiasm, confidence ands clarity on what I needed to do to move on to the next phase. It by gave me the “why” and “how” behind the project. Furthermore, it’s quite invigorating be able to explore ideas and forms though the generation instead of the traditional compositional technique I encountered in my other studios.

process during the computation work.

Ability of the surface/form to reduce/diffuse the reflecting sound generated by the traffic on the bridge. As the “objective” of the design is to “trap” the sound waves and reduce the energy of the reflected sound waves within the structure , the inherent quality of the form to do this will result in reduction of noise pollution to the external environment.

During the form finding exploration, the variation of the

These design criteria will scope my discovery in the explorative

parameters that controls the form will have direct and indirect consequence to the design criteria which I have set up. Having the design criteria will help to reduce the design potentials from the pool of permutations generated from computation work. This reduced set of design potentials can be the basis of discussion/consultations with stakeholders for analysis. The whole process can be repeated for refinement until an optimised form is reached. In view of the problem I wanted to resolve in Merri Creek, noise pollution, I have developed the following set of design criteria to discover the design potentialities of Case Study 1.0 - Seroussi Pavilion by Alisa Andrasek. This will help me to develop my design using the digital morphogenesis technique later in the design phase.

Defined here as the ratio between the voids to the opaque surface/structure, it’s an indicator of how permeable the interior space to the exterior environment. It’s particularly important in adding lighting , transparency and lightness of the structure. Constructability__C3 The term “constructability” defines the ease and efficiency with which structures can be built. The more constructible a structure is, the more economical it will be [8]. To achieve the sustainable objective of the project, I am also looking for material efficiency and constructibility. The target here is to fulfill the primary objective of solving the design problem while providing most realistic cost efficient and sustainable construction. It’s the material performance without looking into specific material per se, but rather the form that can give the most efficient use of material (whatever the chosen material is) This will be a balancing act between the density of the noise dampening criteria versus the porosity of the structure. The more dense the dampening surfaces is the better the noise reduction however this will in fact decrease the porosity of the

criteria structure thus consuming more material for construction.

the design of the built form and the community.

Additionally constructibility also involves whether the design can be fabricated easily versus complex surfaces that is undevelopable for fabrication.

As a result, the aesthetics criteria plays a vital role in community mental and spiritual health as such that it will further promote sustainable living in the community.

Structural performance_C4 This attribute in the design will indicate whether the form require additional support system or not. Desirable quality would be a self-supporting structure where no additional support structure is required to hold the form up. Additional support system requirement will ultimately add to the material cost thus affecting the constructability of the design. Aesthetics_C5 As part of the overall triple bottom line approach (economic, environmental and social) to sustainability I have taken (material efficiency, reduction of noise pollution), Iâ&#x20AC;&#x2122;m also including the social sustainable aspect to the built form. Although building a social sustainable community around Merri Creek will be a complex task, the build form Iâ&#x20AC;&#x2122;m designing will address a small aspect of social sustainability. Social sustainability in this context is to provide amenities while offering distinctive built form to reinforce/create sense of local identity [9] for Merri Creek community. This is in line with the image of the local community which endorses sustainable living and lifestyle. Linking the design and aesthetic of the build form to local cultural values and aspirations will promote greater use of the area thus enhancing social cohesion. The aesthetics of the built form will conform to the local aspiration of the community. This can be acquired through regular consultation with the local community at the design phase. Community buy-in will result in stronger link between

Function_C6 This attribute refers to the ability of the design in producing spatial funtions such as gathering spaces, voids, entrances, rooms etc. For the pupose of the projct I will be ooking at the ability of the design in providing 2 functions : 1. 2.

Access for various types of transportion vehicle (car, vans , busses etc) to go through simulating a tunnel over the existing bridge. Design can create cavity ofr space to host or contain noise absorbtion or dampening surface or material. A desirable quality would be a design that intrinsically feature a surface that can absorb/diffuse noise. A possible compromise would be a deisgn that can host such surface in a parasitic way.

Biomimicry level_C7 There are three levels of biomimicry applications, 1) mimicking of natural form. The second level is a deeper level of biomimicry 2) mimicking natural process. An fninally the ultimate level of biomimicry 3) mimicking natural ecosystem. [11] For the purpose of this project, itâ&#x20AC;&#x2122;s desirable to not just mimic natural but also to go further by introducing performing attributes in the design that mimic natural process or natural ecosystem. Attaining highest level of biomimicry in design puts the design at par with other natural organism that coexist on earth over the long haul i.e. sustainable coexistance.

SEROUSSI PAVILLION /PARIS//2007

“Double charged trajectories are producing internal cocoon like spatial fabric _ a system of veils that unfurls through the space building up continuous yet highly differentiated interlaced field. Wrapped in and in-between cocoon’s swirling fibers are the opportunities for different degrees of cohabitation or humans and art collection _ living with art.” [12]

Taking reference from the self-modifying patterns of electro-magnetic fields, Seroussi Pavilion illustrate how computation work can mimic natural phenomenon to generate interesting geometric form and spatial opportunities. This precedent was chosen as an explorative steps towards finding my own unique technique to solve the design problem in Merri Creek. Although it’s not in the genre of morphogenesis, I can see spatial opportunities and potential adaptation of its sinewy lines that represent the field trajectories.

selection analysis

rom the criteria rating, each successful species have fulfilled at least two or more design criteria which are setup to solve one of the problem of the site, Merri Creek. However this case study did not fulfill critical design Criteria 1 and 2 as the technique used for this design did not address the Noise reduction criteria. An attempt to increase the number of sections/slats out of the field lines may have an opportunity to reduce the noise level however the technique created very permeable volumes exposed to the outside environment. Additionally, such increase also degrade the aesthetic of the built form.

1_ Circular holes on the apex of the domes provide “sky light” opportinities similar effect of the Pantheon’s oculus skylight.

S5_I2 was selected as one of the successful design species as It possess Criteria 3 , 4 and 5 satisfactorily. If the design statement was to search for a meeting place or social place then the arch-like cavernous volumes provides large space for that purpose. This species however introduced an opportunity to create selfsupporting structure which increase the constructability and structural performance ( C3 & C4) potentials. S6_I2 is an interesting discovery. By introducing a spin fields disrupted the original composition however

introduced architectural features to the design. The outcome created “circular courtyards” and entrances which expanded the functions of the overall design. Open air courtyard within the overall composition provides potential public and private meeting spaces depending on the size. S2_I3 and S3_I2 are outcomes of the variation of intrinsic parameters of the design. As oppose to S5_I2 and S6_I2 where I introduced variations in curve profiles and external definition added to the original definition respectively , S2_I3 and S3_I2 are results of varying the parameters of the definition. S2_I3 proposed an optimal number of slats/sections that balances the volume definition to constructability as well as the permeability of the volumes. Whereas S3_I2 introduces the architectural feature of an oculus to each apex of the volumes which can provide better lighting and increase permeability of the volumes to the external environment. In conclusion, the case study design overall failed to address the major requirements of the project. However there are potential design techniques that I can potentially use in my next design iteration.

voronoi morphologies matsys design/columbus/ ohio//2005-2006

voronoi Morphologies is a speculative design by Matsys Design as part of an ongoing research into cellular aggregate structure [13]. It referenced the work of Revano Satriaâ&#x20AC;&#x2122;s research [14] on cellular solid which occurs in nature in form of human bones, natureâ&#x20AC;&#x2122;s honeycomb structure as well as those of cork, sponges and wood cells. The objective of this design study was to demonstrate the use of voronoi morphologies as a tool to convert point-based data into volumetric form. The outcome of this conversion produces structures that are applicable in architecture. These structures can perform to respond to their local context. The project also developed fabrications scripts that unfold the surfaces, add labels and prepare geometry for CNC fabrication. As the

project was a research study, itâ&#x20AC;&#x2122;s highly versatile and implementable on any defined volume. In my opinion the design has been successful in its execution as the technique is adaptable to various application including architecture. Eventhough the case study used rectangular box as the bounding volume for the point cloud, the method can be extrapolated to complex volumes. This will be proven on the next stage i.e. Technique development. The point based conversion into volumetric structure have a strong structural application. A dense point cloud representing concerntrated structural load can be converted into volumetric form to support such load. I can speculate the data cloud can be acquired from the context or initial FEM (finite elements method) analysis of a preliminary design form.

within the technique to reproduce the same intended effect. While there are a lot of similarities to the original work, there are also some differences. The differences are mainly adjustments in the parameters which I would not be able to ascertain accurately. They are parameters such as number of points used in the point cloud and the filleting parameter used. Fig 19. Matsys original work

Helmut Jahn

To discover its deisgn potential thus establishing my own technique which will cater for the deisgn problem I am trying to resolve, the following processes can further extend the value of the technique to the overall design : 1_ Generate point cloud which is not random but rather from data mapping or preliminary load analysis. 2_ The selection of substraction cells are based on a load analysis i.e. retain only cells that is used to support the structure and remove those are not contributing to the supporting of the form. 3_Search for desirable volume Whatâ&#x20AC;&#x2122;s beautiful about this technique is the versatility of the definition which can be applied to any volume which has been experimented by the original designer.

technique : development b.4.2

espite having strong set of potential features for use in for my design in Part C, there are

few issues and shortcomings that require further treatment or innovation before the technique can be fully usable. The technique is is very permeable at its current design iteration. In Part C, I intend to address this design weakness. An option to implement is to apply a boundary condition to all exterior surfaces or using attractor point to modulate the exterior surface to be a close surface. .Additionally , I can also use the attractor points/curve to inform the site and have a graduated openings in some portion of the surface while the rest is fully closed. Mapping of specific local characterics such as traffic intensity, site views or some other relevant atrribute that can inform the site can be a good potential to modulate the openings. The current definition did not have a “algorithmic routine” to cull “floating”

numbers component to generate the centre points of the voronoi cells. When applied to a volume, culling the points that are outside of the volume created voids within the voronoi patterns as such that it created patches of voids on the volume surface. My design intention was the voronoi cells are aligned to the boundary surface to create a seamless surface that reflect the volumetric form. Extruded 2D voronoi pattern or some other geometric pattern can potentially retain the boundary surface, however I may lose the cellular attribute of the design. The fabrication of the technique can pose a great challenge due to its irregular pattern or having the emergent qualities.

Itâ&#x20AC;&#x2122;s possible to explore/emulate welded steel member (possibly Circular hollow section, CHS) with a hollowed steel sheets to make up the surfaces of the voronoi cells. This technique will use combination of steel wires soldered together ate ends with hollow cardboard glued to the wires . In short, each of these technique requires different techniques and ultimately chanegs the overall form and aesthetics of the final form due to their limitations and material constraints. Additionally, the scale of the prototypes has to be considered for each of the technique however by fabricating the form in parts will scale up the model with the consideration of time , material and ultimately cost in mind.

n my initial evaluation, 3D printing was a good candidate to fabricate my model. However after understanding various techniques and 3D fabrication machines, there are serious concerns that compromises the delivery and final finish of the prototype. As

mentioned

earlier,

the

Stereolithography(SLA)approach

is the most suitable for thin and hollow model like my model. The liquid polymers changes state into solid as the laser light traces the polymers and build the layers one after the other once it hardens. The final form is treated to ensure tougher finish. This method is however not available in Fablab and is currently expensive. An alternate method is using the FabLabâ&#x20AC;&#x2122;s ZPrinter 450 that employs ceramic powder in layers bonded together to form the final 3D model. The advantage of this method is that itâ&#x20AC;&#x2122;s a zero waste fabrication as the excess powder can be extracted and reuse. I did not use this method as the model needs to be prepared well in advance by Fablab. I may be looking at this method for my final design when I have more time to prepare the model for submission.

approach is not entirely suitable for my model due to its thin and irregular shapes. The constraint was due to the hollow nature of the voronoi cell which the printer will have to build support for portions that spans the hollow space. This is a wasteful as the support will be removed at later stage. Additionally, removing the harden support from the printed support may compromise the model as itâ&#x20AC;&#x2122; slim and fragile. I was however able to print a massing prototype of the voronoi cells to give an idea of the pattern and form of my technique. As the prototype using the 3D model is an exact replica of the intended design, no additional connection need to hold them together other than gluing the bottom cells to the model base. As mentioned, I was not able to achieve the intended effect of the hollowed voronoi cells, the prototype is merely a suggestion to inform of the overall form of my design.Having the solid characteristic of the prototype, the performance of this fabrication technique is better than the other methods tried on this exercise. The prototype may achieve the strcutural performace criteria however it does not fulfill most other criteria set for the brief.

The approach that I have decided to use for 3D printing is the FDM fabrication using the UP Plus 2 printer using ABS filament. This approach is the most cost effective and accessible in Fablab. However this

Automation of the dimensioning process can be assisted via grasshopper to generate markings/label for assembly and can be etched (score) through laser cutting for assembly. Assembly drawing is also required to identify the connections of all members as well as the voronoi surfaces.

Although, I am referencing steel as the fabrication material, this may not be suitable for this project due to my sustainability objective. This technique performed better under a stress condition applied to it. The rigid connections at the junctions displayed ideal characteristic suitable for actual fabrication. IT also uses less material than the 3D printing approach.

problem while finding suitable form that minimises its footprint on the site. This can be explored in Part C however due to the time constraint, this may not be a feasible approach. It was also recommended that a possible solution to the performative surface can be approached via the materiality of the surface i.e. a porous surfacea. This is deinitely a viable solution to save time and cost effectiveness of the overall project. In conclusion, a thorough analysis will be undertaken to evaluate these comments and their feasibility to be added into the next design stage , Part C.

learning objectives

rom the handbook, the whole experience in Studio Air is driven by specific objectives. In relation to Part B - Criteria Design, I can identifty the specific objectives and how they are being met in my own experience: Objective 1 “Interrogating a brief” - in the tutorial group we were assigned a research topic in this case biomimicry. By researching what biomimicry is and how we can emulate nature through biomimetic design gave us the opportunity to interrogate the brief. We interrogate the brief by developing a set of design criterai which is site specific. The process also took advantage of the nonlinear and iterative nature of digital design specifically parametric design to manipulate options to achieve the brief.

Objective 5 “Case for proposal” - the progressive work within Part B with an eventual delivery of a proposal develop our skills in critical thinking and making a case for design through precedents, analysis and innovation through discovery. Precedent analysis also allows for critical evaluation of “good work” or “successful built work” as a foundation of further innovations in design. Research accompanying analysis and design proposal will furthur substantiate design proposal.

Objective 2

Objective 6

“Generate design possibilities for a given situation” - the iterations of the case studies enabled us to develop technique to analyze design possibilities. The two tiered approach of iterative discovery i.e. Case Study 1 , to explore existing work and spot latent design potentials and architectural features, Case Study 2, to reverse engineer a precedent and innovate through experimentation, when combined became an effective approach to filter design potentialities. Wide range of design tools through GH definitions allows us to fully explore design possibilities.

“Design analysis of contemporary architectural project” - case studies and precedent works are used to develop design analysis.

Objective 3 “Develop skills in various three dimensional media” - the production of the journal as well as the weekly algorithmic task requires that we work on different tools and technique in producing wide range of media such as 3D modeling, diagrammatic analysis, page design as well as image editing. Furthermore, typical of a studio based learning, model making was included however new technique of digital fabrication is introduced. Objective 4 “Develop understanding of relationship between

architecture and air” - the computational nature of digital design isolates us from the actual site. However by bringing the site context, interrogating the site and developing actual model that is site specific tie together the virtuality of computation work with the actuality of the physical site.

Objective 7 “Understanding of computational geometry, data structures and programming” - extensive weekly video and exercises in grasshopper definition introduces many aspects of use of new and traditional geometry in space making, ornamentation as well as performative. Example and exercises in list manipulation and management illustrates the complex nature of data structure. Introductory exposure in scripting illustrates its importance in extending the functionality and potential in visual programming. Objective 8 “Develop own computational techniques” - innovation through discovery when using and mixing different GH definitions. Accumulating personalised definitions through the iterative process and discovering the latent potentials for space making, ornamentation and performative.

b . 7. 0

learning outcomes

y personal learning outcomes are also driven by the objective set out in the course:

Objective 1 “Interrogating a brief” - through personal site visit, developing a problem statement as well as the design criteria that are sensitive to the site guided my design discovery through the technique development. Research in biomimicry and biomimetic design gave me the basis of my explorative work. Objective 2 “Generate design possibilities for a given situation” from the case studies analysis; in Case Study 1 despite the limitation of the possible relevant case study to my area of research i.e. digital morphogenesis, I was able to discover potential space making technique through computation work. Variation of parameters in iterations generated new potentials. Case study 2 further developed my skills to analyze and take advantage of different computational techniques to generate new potentials in design. The explorative nature of the iterative process futher enhances my ability to innovate and develop my own repertoire of GH definitions that generate specific outcomes. Objective 3 “Develop skills in various three imensional media” - I was able to learn new technique in model making using digital fabrication. I also developed new understanding on materiality and how it’s closely tied to the fabrication process or technique. Realizing the limitations of the various techniques will helped me pick the best approach in fabricating my model to achieve my design intentions; massing, prototypes and presentation. My only regret was the I did not have enough time to fully explore the various fabrication techniques. I feel that fabrication is an integral part of computation work. I felt that this experience is not fairly weighted in the learning process despite its growing importance. However I fully acknowledged its importance and hope to acquire the skills in other opportunities.

Objective 4 “Develop understanding of relationship between architecture and air” - constantly interrogating the brief and site allowed me to inform y design especially when I was considering the performative approach in my technique. By mapping the local context, my deisgn can be site responsive and establsihed a continuing link between my design process and the actual physical environment. Objective 5 “Case for proposal” - I felt that I was not taking full advantage of this experience to develop a critical analysis and substantiate my proposal in Part B. I was very conservative and cautious in my selection of case studies and looking back I realize I am able to take design risk and explore more innovative and diiffcult case study to reverse engineer. Objective 6 “Design analysis of contemporary architectural project” - The lack of relevant case studies (Case Study 1.0) that I can select from the list had impacted my ability ot innovate in Part B. Felt that with more challenging examples I could discover more relevant technique. Objective 7 “Understanding of computational geometry, data structures and programming” - I have developed expanded GH “vocabulary” but what’s more imporatnt was my have acquired the essential skill of algorithmic thinking where I have to break down problems into little pieces than tackle these problem one at a time to achieve the overall objectives. I think this learning experience was my more significant breakthrough in my learning experience. Objective 8 “Develop own computational techniques” - I would like to use my Studio Air experience as an additional skills as pary of my overall skill portfolio. What I took from part B, It’s not a style but rather a tool that I can use to inform my design, be site responsive and create performative design that promotes sustainability. 87

C1.3 in search of style : CRITICAL REGIONALISM

enneth Frampton, a architectural historian-theorist, in his essay “Towards a Critical Regionalism” [1] recalls the ideas of Alexander Tzonis and Liane Lefaivre to “rethink architecture through the concept of region” while adopting the progressive qualities of modern architecture. This essentially proposed the idea of using the contemporary technology, in my opinion for this project, the parametric technique as means to generate form that are modern and progressive while using the locality i.e. topography, climate, light, sound to infuence the final tectonic form. Frampton also emphasize the sense of touch over visual sense as the response to this approach. In this case I argue that for my project the the sense of touch may not be as significant as the distance and function of the structure (sound barrier) may not allow such sensory to be experience effectively. However I do feel that the tactility of the “touch” can be represented by the variation of the noise level interspersed with the sound of nature provides a different sensory experience to the users.

Although, the surface patterning of the 2D voronoi reflect the complexety of the design, it’s however projected to a simple geometry of a 3D sine wave skewed to response to the site conditions. The outcome of this combination I hope provide an interesting constrast and contradiction. As put forward by Tzonis and Lefaivre, critical regionalism do not need to draw directly from the context[2] It can be detached of its context and used not in a familair way but strange or unique as proposed in the project. Drawing upon the works of Critical Regionalist, Rafael Moneo, such as the Kursaal Palace in San Sebastian reflect the monumentality of the design, detached from the urban fabric but playing a role as a monument to the city. I wanted to create similar effect with my design The scale of the “barrel” vault suggest its massiveness yet the space created underneath are open and preserved its function for the 2 way traffic.

The monumentality of the design is also hoped to fulfill one of my design intent as a visual treat to the locals and hopefully generate enough buzz, negative Figure 1 : Säynätsalo Town Hall by or positive alike, contributing to the Alvar Aalto [1] architectural discourse.

The The sine curve can be read in plan as well as longitudinal elevations. The variation of the curvature in y and z direction can be controlled by dividing the v-parameter in the sine function (3) [4]

DIFFUSER PANELS The sound diffusing cells consist of 2 parts (1) enclosure cell (2) performative sound diffuser. The enclosure cells are made of either thick treated plywood or glulam laminated timber panel. These are fabircated through the CNC milling process at the factory. The second element is the sound diffuser panels which are made of porous sound deadening foam or porous Class A thermoplastic which can diffuse wide frequency range. These panels are mounted into the enclosure cells and position to face towards the center of the road for optimised sound diffusion and absorbtion. The panels themselves form a rigid base for the subsequent cells above. The diffuser cells is anchored to the bridge by steel brackets (shoes) using bolt connection.

C 2.1.1 Tectonic_ voronoi cells

VORONOI CELLS Voronoi cells are made of moisture and rot resistant marine plywood bolted together by customied angled steel brackets. Brackets are cold form steel which have combination of round holes for boltings and performation of diamond holes for cuttting and bending to size and appropriate angles. Plywood are cnc mill cut to size and engraved with part ID.

AUTOMATED MACHINE CODE GENERATION For production, grasshopper will not only generates the exact geometries of all the parts of the voronoi cells that makes up the structure but also the numbering sequence to allow easy assembly (see below convention). The cutting templates are laid out and nested on glulam panels and marine grade plywood boards for milling. G-code generator (http://www.shopbottools.com/controlsoftware.htm, http://www. grunblau.com/ghcode.htm) can be used from Grasshopper to generate G-code to control CNC-router. It will generate the appropriate codes to engrave the part ID onto the glulam/plywood as well as drilling the holes for connection.[5]

learning objectives

rom the handbook, the whole experience in Studio Air is driven by specific objectives. In relation to Part C - Detailed Design, I can identifty the specific objectives and how they are being met in my own experience: Objective 1 “Interrogating a brief” - in Part C , the process of interrogating the biref is a significant undertaking where intensive study of the brief will reveal the project requirements which then be compared against the site analysis. Objective 2 “Generate design possibilities for a given situation” - in Part C, the design possibilities are more focused and driven by the combination of the site analaysis geographical,environental and cultural context , with design intent. Whereas Part B focuses on purely on the design potentials generated from the technique, Part C uses these potentials to solves and fulfill the design intent. Objective 3 as per Part B. Objective 4 as per Part B. Objective 5 & 6 “Case for proposal” + “Design analysis of contemporary architectural project” - Part C brings the justifications for the design to fruition. Precedent analysis done in Part B suggest the development of the technque for the project while in Part C, additional precedent studies will asisst in substantiating the revised technique or/ and form finding. Objective 7 as per Part B.

130

Objective 8 as per Part B.

C 4.0

learning outcomes

y personal learning outcomes are also driven by the objectives set out in the course:

Objective 1 “Interrogating a brief” - in Part C, the process allows me to list out what is the project objectives and compare that to the site analysis which I have previosly done in Part B. This process allow sets out the task I need to undertake and influnece the final approach in terms of the technique that I have researched and how I can adapt that technique to achieve the project objectives. I was also influence by my exposure to deisgn syles introduced in my architecture history subject. The post-modern approach of critical regionalism which combines the modern architectural tradition with the specificity of the site (environmental, material, culture etc) . Objective 2 “Generate design possibilities for a given situation” Whereas in Part B, the exploration of the design possibilities generated from the technique gave me of hints of what I can use for my final design, in Part C the technique was further modified and refined iteratively through the combination of further studies from site analysis as well as prototyping to achieve the optimum soluion for the final design and built. Objective 3 as per Part B.

Objective 5 + 6 “Case for proposal” + “Design analysis of contemporary architectural project” - the outcome of Part B and the interim design critique had questioned the suitability of the technique I have chosen to resolve the design problem. I have adapted the technqiue and undertaken another precedence study to help me build a case for the revised technique. I have learnt to let go and not hang on to my first attempt to resolve the problem but used the industry responses and further analysis to develop a more refined approach that fulfill the design and site requirements. Objective 7 “Understanding of computational geometry, data structures and programming” - in Part C, I am was able to extend my grasshopper techniques to cover other advanced areas such as data structures and programming using python to solve complex design problem. The breakthrough I had experince in Part C was to build an expanded grasshopper definitions based on my prexisting collections. I now undertand how to use grasshopper effectively by breaking up design problem into its “atomic” level and thread these solutions together to form collective resolution to the overall problem. Objective 8 as per Part B.

Objective 4 “Develop understanding of relationship between architecture and air” - in Part C , I recognized the challenge of transforming the design to which only exist in the virtual world into something buildable and scaled appropriately to the real world. In doing so, parametric design helps me to adjust the necessary parameters to scale the project to actuality such as the the width, length and height of the design. This in itself is an iterative process that involved prototypying , rationalizing and understanding materiality of things.
