Introduction

Wei Wen Jun The University of Melbourne Bachelor of Environments Architecture (3rd year)

y name is Wen Jun Wei, a third year architecture student born and raised in Taiwan. Since moving to Melbourne in 2012, I have developed a strong interest in creative designing and architectural theories throughout the course. My first exposure to digital design came in the first year whilst studying Virtual Environments. This course involved using Rhinoceros 3D digital modelling software in conjunction with panelling plug-in tool to manipulate designs. Throughout the course, I was able to transform a virtual design into a physical one from complex NURBS surfaces into rational surfaces for fabrication, in order to build an architectural piece to the scale of human body. The experience with digital design was rewarding and it had attributed me insights into the complexity of digital world. Despite having the previous experience of digital modelling and paneling design, I consider myself still having a lot more to learn and grow. I see this course, Architecture Design Studio Air as an opportunity to broaden in both theoretical and technical knowledge in architecture. Despite the knowledge of digital architecture I gained in the past two years, myself is still fresh to the parametric language, piratically in Grasshopper. Knowing to comprehend this new language is not going to be easy, but I believe such tool will add my creativity and free my imagination in a computational sense.

“The computer offers another kind of creativity. You cannot ignore the creativity that computer technology can bring. But you need to be able to move between those two different worlds.” - Tadao Ando

Design Futuring

Part A1

Design Futuring Design Futuring l Land Art Generator Initiative

he climate change and destruction of the planetâ&#x20AC;&#x2122;s natural environments are now being more widely recognized as challenges today. As a matter of fact, we human beings are facing our nemesis. We have created this condition unwittingly as we have been taking resources from the planet for granted. While innovative practices such as sustainable designs have emerged, efforts towards change remain unacknowledged. Fry argues this relation between creation and destruction is not an issue when a resource is renewable, but it is a disaster when it is not.[1] The notion of revaluing design as a world shaping force is vital in order to have a sustainable future. The reason being is that design plays a significant role in shaping every part of our lives. To understand the true power of design, we need to redefine its identity. In Fryâ&#x20AC;&#x2122;s words, design is not an independent entity but it influences, and is influenced by social, cultural, ethical and political means[2] ; thus, design can be rethought as futuring, to acknowledge the move from passive consumption to active participation. I agree with his view as followed by such way would reveal the power of design - to redirect practices to sustainability.

In a much closer discussion, the reception of the importance of architecture seems continually growing as a decisive role in our future. Indeed, what makes architecture great is not about its capability of being sustainable, but rather an influential force to educate users being sustainable. This notion will be my conceptual intent that drives the design of this project, which will be further explored in the journal. Going back to the notion that architecture as a design practice that contributes ideas to the ongoing disciplinary discourse and culture at large. To expand future sustainability, it is important for a degree of engagement to take place between the user and architecture itself. Certainly, I believe that design futuring is not about achieving a sustainable equilibrium, it is rather changing the attitude by which our lives are sustained.

Design Futuring

supertees Grant Associates Singapore 2012

The colossal Supertrees are found in the Bay South garden in Singapore. The Supertrees act as vertical gardens and are embodied with renewable energy and water technology integral to the conservatories. The government intends to transform Singapore into a vision of â&#x20AC;&#x153;city in a gardenâ&#x20AC;? in contrast to its dense urban environment. It aims to symbolize the importance of revaluing natural balance and raise awareness of the environment globally.

Design Futuring

The very powerful picture behind Supertrees is that they breathe life into Singaporeâ&#x20AC;&#x2122;s urban oasis and expands future possibilities. Supertrees are a rich fusion of nature and technology taking inspiration from the form of the orchid. They act as cooling ducts for conservatories, collect rainwater for irrigating vegetation and are embodied with photovoltaic systems to generate solar power on-site. These sustainable features are appreciated because they refocus society from passive material consumption towards an active participation by a mean of ethical use of design as a force in repositioning the habitats.

This is a successful project for the reason being that it encapsulates the notion of design futuring, providing both leisure and education to the nation. The features of bridge and skywalks connect taller Supertress allow users to engage with nature from a spectacular height. Through the engagement with users, it changes the attitude by which our lives are sustained. In Fryâ&#x20AC;&#x2122;s words, ever design decision is future decision.[3] In light of contribution to the ideas, this project is remarkable in educating sustainable energy rather than merely sustain energy.

Design Futuring

Urban Adapter Rocker Lange architects

Hong Kong 2011

Through a series of various seating arrangement, Urban Adaptor seeks to achieve an adoptive realm that reacts and interacts to its site and inhabitants. The variation of its style is obvious where there is a lack of uniformity in its formal expression. Each of them is designed to convey different set of formal expression. It seems to foster a unique Hong Kong identity, a culture that is international. These generated functional surface are being appreciated and engaged. As they invite multicultural users to new seating and communicative arrangements in the urban space to establish the connection to Hong Kong’s unique identity in both functional and educational manner. One important note about this parametric precedent is that it is a holistic scheme that utilizes site information and programmatic data to react and interact with its environment. Instead of offering a fixed form of single static design, this scheme expands a futuring thinking that suggesting multiple solutions to adapt to different site conditions and programmatic needs. This suggests that the development of computational simulation creates more responsive designs and allows more new design opportunities can be explored. This approach has became more appreciated today and the idea behind can be adapted to future design projects. This notion is engaged with Sean Ahlquist’s theory about computation in which he suggests that “processing information between elements that constitutes specific environment is able to provide a framework for influencing the interrelation of information with the capacity to generate complete order, form and structure”. [4] By seeing how this project achieves its adaptive nature through parametric approach, I realize the need for engaging computing in designing in which to expand future possibilities. To unfold the benefits of using computers in the architectural design process, two different design techniques, ‘computerization’ and ‘computation’ will be explored and compared in the next section Part 2 - Design Computation.

Design Computation

Theories of the Digital in Architecture l Architecture’s New Media l Architecture in the Digital Age

orking with computers to aid in architecture design process becomes apparent in the recent years. Digital modeling constantly changes the world of design and engineering, increasing the complexity and capability of what can be designed and built. It seems exploring and exploiting new methdologies of computation is key to fabricating innovative designs and expand boundaries of possibilities.

The evolution of digital in architecture in interaction with new technologies also causes ongoing changes within design and construction industries. Digital in architecture was merely the operative model of formal generation in design within the last decade, it had emerged beyond representation as Rivka and Robert suggests, “recognition of computational processes emerging technologies of materialization in generative processes.” [2]

The use of digital modeling software is shifting architecture from the drawing to the algorithms in designs. Brady describes computational design “attributes designer’s intellect to capture not only the complexity of building a project, but also the multitude of parameters that are instrumental in a buildings formation.” [1] Rather than designing in conventional ways, computational design has opened new territories of formal exploration in architecture in which forms are designed by generative process.

In synthesizing materiality and technologies, the relationship within computer and architecture is redefined from ‘design to production’ to ‘form generation to fabrication’.[3] The shift of technology changes the constructability in building designs to a function of computability. Complex geometries like NURBS curves and surfaces become constructionally possible by means of fabrication process, which opens up opportunities for exploration of new geometries.

ZA11 PAVILION

Dimitrie Stefanescu, Patrick Bedarf, Bogdan Hambasan

Computerization approach is a more traditional approach that utilizes computer as vidual drawing tools to execute existing procedures that are already preconceived in the designer’s mind. To illustrate this approach by Zaha Hadid’s Edifici Torre Espiral. Its conceptual design in of design process was already conceived and sketched out on paper prior to being manipulated by computers. On the other hand, computation uses digital model to digitise information through a generating code. To explore architectural spaces and concepts through algorithms. Rather than designing the outcome, it engages more directly with the result of generated system to explore further design potentials. An illustrated example here is ZA11 Pavilion in which the design was elaborated upon the system of Biomimicry that mimic hexagons. This mode of working is redefining the practice of architecture, which taking on an interpretive role to extend the capability of dealing with highly complex problems.

Design Computation

The Yellow River Art Centre put attention on the geomorphology which is an observation of natural land formations. There is no doubt that a huge amount of digital aided elements are employed to visualize layers and textuaries the facade in order to implant an identity that echoes characters of the riverbank. Rather than defining the framework to influence the interrelation of information in the design process, its use of parametric techniques adds significance to its architectural form and the gradation of elements in the building facade. Upon its

underlying principles in the design process, this precedent is argued to be designed from an approach that is more computerised rather than computational. This case study suggests that emerging of a digital materiality in design, ‘fabrication technology’, has became a leading technological and design issue in the architecture design process. The Yellow River Art Centreis is constructed with GRC (Glass reinforced concrete) technologies. This construction technique allows for the seamless

transition of data from digital materiality to fabrication, removing human error from the construction process. It was employed with CNC milling machines, in which each panel was fabricated as a form to which concrete was poured with fiber-glass in order to create a very thin strong mould. [4] The digital materiality in architecture lifts up the capacity to solve complex design issues. As Mouzhan Majidi said: “This hasn’t simply transformed what we can design – it’s had a huge impact on how we build.” [5]

Design Computation

The Bao’an International Airport in Shenzhen is the largest parametrically defined free form structure and facade in the world, which covered on a perforated cladding consisting of 50,000 different facade elements and 400,000 individual steel members. [6]

This precedent is a clear example of computational approach where a defined algorithms is computed to give rise to the final design of the Bao’an International Airport. A parametric data model, panel morphing, controlles the size and slope of the openings, which were adapted to meet the requirements of daylight, solar gain and viewing angles, as well as the aesthetic intentions of the architect.

The highly sophisticated tectonics of the building is suggestive of its complex composition. A conventional approach would be difficult to compliment man’s creativity whereas computational approach has the potential to provide inspiration and go beyond the boundary of intellect. This is supported by Brady Peters’s discussion of algorithmic thinking as he describes “computation augments the intellect of the designer and increases capability to solve complex problems.” [7]

Composition Generation

Part A3

Composition Generation

The Building of Algorithmic Thought l Definition of Algorithm l Guild to Renewable Energy Technoloies

he use of digital in architectural design process has existed for quite some time. However, conventional approaches by means of simply digitizing entities that are preconceived in man’s rational becomes inefficient to coup with the emergence in complex systems. In responding to such phenomenon, computation undoubtably is redefining the practice of architecture, which had given rise to the shift of architecture practice from drawing to algorithm, in parallel to the shift from composition to generation. The action of empowering computers to generate complex forms furthering the intellect of a designer’s creativity and capability to solve complex problems. The algorithmic thinking takes an interpretive role to design the process of generating system rather than the outcome from itself. This allows the exploration to be versitile during the design process to achieve desired outcomes in a shorter period of time. In this important way, the shift from composition to generation propels architecture into a new paradigm of innovative designs. In reacting to the shift from composition to generation, computation had evolved as an integrated architectural form. Especially given complexities of architectural

form and construction today, parametric modelling not only works but has became essential to build large projects. Unlike conventional approach, computation as a new design approach that is developed to link the virtual environment with the physical environment where architects increasingly have the capability to explore building systems and building environments as a whole. [1] This could lead to a future where architects are able to capture and communicate designs through performance feedback between users and habitats that are updated in the digital model. At a higher degree of ability to generate designs, the computational architecture is no longer just a focus on the formal aspect of design. The shift from composition to generation certainly had given rise to freedom in our current position to explore beyond the surface qualities. Particularly, scripting language such as RhinoScrip and Grasshopper allows architects to customise their design environments in which further opportunities can be explored through modification to the program. As suggested by Brady Peter, “we are moving from an era where architects use software to one where they create software.” [2]

Computational approach

Materialization Fabrication

Upon earlier researches of architectural precedents, I have came to appreciate the use of computational approach in architecture more and gained a strong interest in fabrication in particular. As suggested by Jan Knippers, computational design requires a new interpretation of construction process and such invention of technologies will continue to cause shifts in our disciplineâ&#x20AC;&#x2122;s definition and boundaries. [3] I believe that the computational design in conjunction with fabrication technology will even more greatly affect the processes of design and delivery. Furthering the connection of architecture to users and to the society. To support this argument, precedents designed using parametric software in relation to fabrication will be examined in this section.

Composition Generation

BanQ

office dA Boston, USA 2008

Computation certainly plays an important role of redefining the practice of architecture in the shift from composition to generation. In contrary to the predominate use of Computer Aided Design (CAD) today, computation design externalizes the relation between digital materiality and material fabrication. Arguably, it is important for architecture as a material practice in understanding of form, material, structure and environment as a complex system that can be explored through integral computational design process and fabrication.[4] BanQ is one of the computational designs that exhibits reciprocities of form, material, structure and environment. It unfolds plywoodâ&#x20AC;&#x2122;s performative capacities from the synthesis of computational design and physical materialization.

This project was challenged with the task of creating the functional aspects of a dinning space. The architect took a computational approach by sectioning the form into a waffle grid structure to create a fluctuating activities of the restaurant space between ceiling and ground. A striated wood-slatted celing was generated through the use of parametric modelling, which results a seamless landscape that conceals the view of the mechanical, plumbing, and lighting systems above. The linkage between conception and production was eventually realized through CNC (computer numerically controlled) fabrication. Computational design information is used in fabrication which driving rapid prototyping and allowing for precise positioning of cut outs. This suggests that material fabrication has now emerged as a leading technology that affects the process of design and delivery.

Custore Pavilion Anna Dobek Mateusz wojciciki Warsaw, Poland 2013

A similar approach was taken for the Custore Pavilion designed by Anna Dobek and Mateusz Wojcicki. This commercial pavilion reveals the aesthetics of celebrating horizontal attitude rather than the vertical one like BanQ. One important note about this parametric precedent is the interpretive role of algorithm does in the design. The use of algorithmic thinking to shape the pavilion led to the exploration of new ideas. Regardless of its interior shape, the scripts defined in Grasshopper gave them opportunities to continuously experimenting with the properties of pavilion joints and material consumption. Through the manipulation of initial parameters, included its size, material type and density of its application. It eventually achieved a theme that is appropriate for the commercial market in which a translucent barrier

between a strongly geometrically defined exterior and a soft interior.[5] The emerging contemporary design culture however might lose its capacity to accommodate tectonic expression as a â&#x20AC;&#x153;poetics of constructionâ&#x20AC;? as described by Frampton in his critique of the Virtual Materiality of Digital Design.[6] On the other hand, within the renewed relation in materialization and fabrication from these two built examples, it can be argued that the ability to model the structures of material systems as tectonic systems has given new meaning to the discourse in the architectural design practice. This suggests the integration of digital materiality enables tectonic expression to be derived from the realm of digital materiality and material fabrication.

Conclusion

Part A4

Conclusion Part A Conceptualisation l Design Approach

esigning for a sustainable future is a goal as well as a challenge for architecture today. Architecture has been taken as a decisive role in determing the future, not only begins to conceptualize issues on what is to be built but also how it will be built. Innovative designs that contribute to sustainble future is not about its capability of being sustainable, but rather an influential force to educate society being sustainable. That is, in order to expand future sustainability, it is important for a certain degree of engagement to take place between society and architecture itself. In relation to the idea of design futuring, engagement with computing becomes necessary. While computerisation

makes the realization of design possible, computational approach and algorithmic thinking push it further, augmenting the intellect of the designer and increasing capability to solve complex design problems. The parametric language undoubtably is redefining the practice of architecture, which had given rise to the shift of architecture practice from composition to generation. In respond to the design brief, redefining the attitude by which our lives are sustained through the engagement of users with the public art installation will be the conceptual intention. It will be approached through algorithmic exploration of parameters to generate a suitable design outcome.

Learning Outcomes

Part A5

Learning Outcomes

Theory & Practice of Architectural Computing

eveloping proficient skills in a completely new design software had been difficult. As if being pushed into a pool of knowledge that we did not know what to expect at the beginning. However, everything seems to come together after subsequent learning experience of theory and practice of architectural computing. By learning grasshopper, I came to realize the capability of parametric design is not simply a tool of generating abstract form, but its potential to generate further options to solve complex design problems. While my computing knowledge is still at its introductory level, I believe that the learning outcome of algorithmic thinking will aid to my future designs.

It is true that computation is redefining the practice of architecture and causing a shift from composition to generation. On the other hand, computing is merely a tool that facilitates tasks in the design process. We, however, must not be fully ordered by what the computing performs but rather choose the right computational approach to suite the design problem. In Tadao Andoâ&#x20AC;&#x2122;s words, â&#x20AC;&#x153;The computer offers another kind of creativity. You cannot ignore the creativity that computer technology can bring.â&#x20AC;? Thus, it is important to being able to move between these two different worlds. I believe that every new information that I come across in this new world of parametric design serves as a piece of puzzle for my personal discourse of architecture.

Algorithmic Sketches

Algorithmic Sketches Parametric modeling l Computational design

he parametric generation of gridshell is the most interesting outcome I have generated throughout the learning experience of Grasshopper. I was amazed by how quickly a versatility of forms can be generated through computation. It proves me that computation is capable to argument the intellect of a designer and increases his or her capability to solve complex problems. The illustrations also show that parametric design in 2D and 3D pattern have been useful to explore the forms and structures. Further exploration in integrating multiple computational techniques in the material systems would be ideal to generate a suitable design outcome for Part B. This is the reason why I chose to study a different computational technique from what I researched in Part A3. I intend to integrate the techniques I have developed here and sectioning (from Part A3 precedents) to broaden the design opportunities and generate an appropriate design outcome for the next section Part B.

Part B1

Research Field Material system: Strip and Folding

Approaching towards the case study, the material system of Strip and Folding were chosen for our exploration purpose. We are convinced that its fluidity and continuity characteristics are suitable for constructing an interactive community space. Supported by Moussavi’s argument in the paper of The Function of Ornament, “when the idea of randomness is fully understood, the sense of intuition can be expressed without restriction when demonstrating a parametric design”. [1] If we perceive Strip and Folding based on the interpretation of architecture, we realized its fluidity attribute could further link with a dynamic overview in our final design outcome. However, we are also aware that giving aesthetic manner alone to parametric design is never enough. As Moussavi mentioned, a fine piece of architecture should complete a body of integration which consists of both functional and representational features.[1] The intended design approach in Part B will be using Seroussi Pavilion as the starting point to explore the form of sculpture design (representational feature) together with the installation of sustainable energy (functional feature).

It is important to consider urban settings and cultural respect into the design to provide a function as interactive community space. In Moussavi’s words, he mentioned that “apart from its exterior, interior design could be independent to create a different sensation to users”. [1] We proposed to enhance the level of interaction between users by customizing spatial aspect to serve as educational purpose. That is, the design outcome would be favorable not only in terms of its aesthetic beauty but also being an interactive space to create the awareness of sustainability.

Shimmer concept

The Shimmer Concept is a futuristic architecture design which aid to improve the standard of well-being by introducing natural movement, noise and natural light dispersion into human living space. [2] Stripes presented in the design promote flexibility for light and wind to enter. They act as important medium to enhance the interactivity between interior surrounding and exterior environment. Shimmer Concept promotes the similar principle with â&#x20AC;&#x2DC;Strip and Foldingâ&#x20AC;&#x2122; which focus on the continuity created by different curvature. In this precedent, unpredictability and constant changes in nature have given inspiration to develop through transformative spaces. Asymmetrical form which shaped this

case study possessed interesting gestural representation that incorporates with sunlight and wind. By connecting the design with nature, interaction between users and environmental space can be achieved. Hence, the feature of sustainability is introduced in this design with the aim to promote a better living sensation for the users.

Seroussi Pavilion Biothing Paris 2007

Seroussi Pavilion by Biothing clearly shows the material system of strip and folding. It uses adaptive mathematical logics that allows for localized differentiation where the mathematics of electro-magnetic fields are used to derive the form. Electro magnetic fields (EMF) are conceptualized as primary vector points to cultivate different possibilities where attraction/ and repulsion of field charges are manipulated. Using mathematical rationale, different frequencies of sine function are further incorporated to manipulate its form. Seroussi Pavilion demonstrates the possibilities of a simple and yet visually appealing structure.

Case study 1

LAGI Rainbow Cloud

Chie Fuyuki & Lichao Qin 2012

Rainbow Cloud is the competition entry we examined of from the Land Art Generator Initiative 2012. This project is inspired from the behavior and formation of clouds. By appreciating its ubiquitous mass and random form, Rainbow Cloud is designed using thousands of â&#x20AC;&#x2DC;balloonsâ&#x20AC;&#x2122; which will involve in collection of energy. These balloons attract each other to form a giant cloud in the sky, if not repulse one another when it is in use for energy collection purposes by users. It would also vary into different tones of colours based on the rate of energy collected. It is a dynamic design where it enhances interaction between people, at the same time creating awareness regarding ecological issues. [3] We are convinced that Rainbow Cloud expresses several similarities that are aligned with the core focus of Seroussi Pavilion. These two projects originated from the concept of realizing the pathways which are attracted to the source. In this case, more than one source of attraction/ repulsion is introduced to create a complex tessellation where striking aesthetics can be observed.

Upon the analysis of Seroussi Pavilion in conjunction with Ranbow Cloud, we argued that parametric designs alone will not be satisfied in expression of an ideal architecture that possess an interactive environment to users. Computation only puts us into an advantage position where precision can be promised. We believe that other considerations such as technology and construction materials have to take into account in order to produce a parametric design that is suitable for the real world. This aspect will be further developed in Part B4.

Parametric modelling consists of infinite possibilities to form different species from one primary source. In this case study, the given grasshopper definition of Seroussi Pavilion was breakdowned into simpler form by changing existing parameters, input geometries and component options. The aim was to develop unexpected outcomes, experiment and push the capabilities of the definition. Five species were developed to explore the potential of 2D spatial organization and 3D spatial arrangement.

This allow us to understood the primitive mechanism of magnetic field influenced on Seroussi Pavilion. 2 The second species customized the first species by adding spin force to explore on the dynamic movement and continuity flow of magnetic field. The intensity of strength, size of radius and rate of decay were also adjusted to experiment different possibilities of form. By adding or re-positioned the spin force would also aid in the study.

1 This iteration possesses the most fluid form compare to the other three. The number of spin force decreases as they get further away from the core. It allows form to be express in a flat spatial organization. This iteration has a flat characteristic that may be suitable for underground context if further develop. In terms of adaptability of sustainable technology, geothermal energy harvesting would be best to introduced to this iteration. 2 A good demonstration of â&#x20AC;&#x2DC;Strip and Foldingâ&#x20AC;&#x2122; can be seen in this iteration. By incorporating attractor and repulsor component into the subject, a bloated form of lines and curvature is produced.

feature of sustainability by adding turbine onto the location of point charge. 4 The graphmapper allows iteration to be visualized as a 3D form. However, it is incomplete in terms of volumetric and complexity. However, it still has a very strong potential to flourish into a desirable outcome. With several point charges extrude vertically up and declined, this iteration favours the installation of solar panel at the top of these column-liked formation. In this case, clean energy can be generated by using solar energy to achieve sustainability. Although these iterations may look continuous and dynamic for its aesthetic appearance, they are still far from completion in terms of constructability. An interactive space that creates awareness among users would only be realized if structural aspect is satisfied. Hence, the combination of a social living space and clean energy generator would be achieved. As conclusion, designâ&#x20AC;&#x2122;s structural rigidity and real world consideration should be the core focus for further research exercise.

B3.1 Case study 2

Beijing National Stadium is the world largest steel structure with unwrapped steel used. This design combines a pair of structures: a brightred concrete bowl for seating and the iconic steel frame around it.[4] Structural integrity of this design mainly lies on the steel framework. The vertically positioned steels resist compression and transfer loads to the footing below; horizontal positioned steels stabilize the load act on the structure and maintain its design form.[4] It is amazing to understand how architectural design intent can have functional uses which contribute to the design’s structural integrity. This design gives us insight to solve the constraint from previous case study where forms were simply composed of lines without the consideration for material construction. Forms were generated for conceptual references only. However, in this case study, an advance level of computation has pushed ‘Strip and Folding’ to its maximum potential. By giving solid 3D form to this abstract conceptual design, ‘Bird Nest’ earns an opportunity to exist in the real world as true architecture.

Case Study 2 Case Study 2

This design technically started out with a simple form with added complex geometry onto it. The calculation is so numerous that software is needed to ensure the web of twisting steel sections fitted together. In this case study, we are particularly interested in discovering how the random strokes of steel lattice are produced using computation. Its lattice structure is being dynamic. Random strokes not only portray a strong movement sensation but also act as a medium to enhance the interactivity between interior surrounding and exterior environment. In the previous case study of Serrousi Pavilion, computation method had been used as tools to generate form. In this case study, however, we have shifted our focus to generate desirable structure for the means of incorporation of sustainable energy and its aesthetic characteristic.

B4.1 Species & Iterations

In the first species, alteration of Bird Nest’s parameter is made. Points are shifted to enhance different intensity of dynamicity. Besides, the alteration enables difference aesthetic continuity as curves are randomly reduced.

In the second and third species, researches are stressed on Bird’s Nest structural exploration. In these species, a new plugin ‘Weaverbird’ is introduced to experiment different structural attributes. Meshes are altered to intensify the complexity of curvature and continuity characteristic in real form. Frames (WbFrame) are added not only to improve the aesthetic appearance of the species, but also contributing to structural integrity.

By keeping ‘Weaverbird’ as a key plugin, all the framings are modified into windows in the fourth and fifth species. New excitement is found in the exploration of Bird Nest’s structural variation as a difference form of aesthetic and material innovation can be achieved here.

B4.2 Selection Criteria & Outcomes Apart from the brief criteria, the selection criteria our team decided include aesthetic appearance, potential for further development, and fabrication possibilities (see page 44) require thorough consideration in order to push this measure to its optimum standard.

Hence, by exploring a problem’s logical conclusion in depth, creating several alternative ways out and prioritizing the most promising solution, only design confusion such as materiality selection, structural integrity and aesthetic appearance can be solved efficiently.

By referencing the ‘search’ concept from Kalay, it is mentioned that in order to obtain the best result, problems have to be tackled by producing candidate solutions for consideration and choosing the right solution for further consideration and development.[5] As Kalay proposed, any difficulties encounter in selection criteria can be solved if when solution includes following aspects:

A few suitable iterations in previous species were selected to further develop in order to approach an ideal structural form in species ninth and tenth. Main focus heavily lies on prioritizing structural aesthetic of Bird Nest. In species ninth, both grasshopper definition: window and frame are emerged together in order to enhance better structural complexity and visual appearance. In species tenth, the customization of WbFrame gives extra texture to Bird Nest’s substructure which directly contributes to further materiality selection and fabrication possibilities.

perceived visual and noise impact of wind turbines in the landscape. The solution was to encourage public support for windpower by creating a community-owned facilities and using local skills.

Denmark government intends to increase the use of wind energy from supporting 22% of nation’s total electricity consumption to 50% by 2020.[7] Denmark government incentive has favored large amount of investment in research and development to improvise the efficiency of wind technology, and of course reducing cost. These therefore, lead to our interest in using windbelt technology as its potential continues to grow positively. Above: Denmark Government’s Proposal of increasing wind energy usage

A NOTE ON FANS The Classic Windbelt will only work well with a powerful fan. It works best with wind speeds of 15mph (7m/s) or higher. High quality metal fans tend to be more powerful than cheap plastic ones. A metal cage is one sign of a strong fam. When shopping for a fan, another good indicator of fan power is the amount of electricity it draws. Look at the specs to find amperage. Many weaker fans draw less than 1 amp. These will Belt not work. Look for a fan that draws around 2Sators amps.

Windbelt Design

In our team first attempt, metal clips are designed to position windbelt in place. However, this method limits the movement of windbelt, which might eventually reduce the efficiency of energy collection. Joining blocks with metal clips too, would lock the windbelt facing to only one direction. This method is also not desirable as wind direction may vary at different times. Instead of locking it, our team decided to penetrate a round bar at the edge of the belt to allow flexibilities for different angles.

Using the previous attempt as a stepping stone, our team eventually complete the design structure by adding an â&#x20AC;&#x2DC;adjust ballâ&#x20AC;&#x2122; into the rigid locking system to enable optimum rotation movement towards all direction and angle.

Upon the idea that â&#x20AC;&#x2DC;windâ&#x20AC;&#x2122; is the most dominant natural resource at the site, the organic form of lattice structure of our proposed design was emerged from the wind diagram study. It integrates wind belt technology to create an dynamic environment that stimulate visitors to visualize wind movement and sensing the sound from wind belt, thereby encouraging the awareness of renewable energy. The design aligns with computational approaches for flexible and innovative outcomes where the form was followed by the dominate wind direction to determine the most efficient angle for wind belt installation to optimize the efficiency.

Materiality

At this stage of development, seeking of suitable materiality for the design is crucial. As it not only contributes to the aesthetic appearance but also structural integrity of the whole design. Hence, our team has look into various types of possibilities, particular in renewable construction materials.

Technique: Proposal

Bamboo is one of the most efficient renewable materials in the planet. When 30 to 50 years are needed for harvesting of conventional timber, bamboo only needs 3 to 5 years to be ready. Furthermore, their light and high strength coefficients characteristic ensure structural integrity. In our design, bamboo material will be developing for the use of construction substructure frames. In this case, carbon fibre joint would consider as a connection to link bamboos to form complex structural forms.

Paper and Cardboard Tubing, also known as Shigeru Ban catches our attention due to its high load bearing properties.[9] With beer crates filed and sandbags as its main components, it is recognized as a cheap material which also possessed a characteristic of fire resistance. In relation to our case study, our team decided to use this material as our primary structure due to its rigidity and high tensile and compression resistance. Using Taiwan Paper Dome as precedent, different structural construction method with the use of Shigeru Ban can be replicate and fit into our design.

The trending material Ethylene Tetra Fluoro Ethylene (ETFE) foil is an ideal material to replace conventional glass. It has attributes similar with glass which are transparent and corrosion resistance. However, it only weighs approximately 1% of glass weight and offers flexibility for bending and folding due to its thin characteristic. [10] Hence, by using Beijing Olympics Aquatic Centre (Water Cubic) as precedent, our team would be investigating on how different sizes of ETFE foil are installed into its primary steel structure. By exploring the precedent, adaptation of ETFE foil into the designâ&#x20AC;&#x2122;s frames and windows would be more well organized and simple.

Learning Outcomes

Although a lot of progressions have been achieved until this stage, there are still some defects and incompleteness which are needed to be concerned. One of the main adjustments from structural material has to be improvised. Paper and Cardboard Tubing also known as Shigeru Ban only possessed minimal water resistance and weather proofing characteristics even if coating layer is applied. Using this material as the design primary structural body causes frequent maintenance overtime which leads to high cost. Thus, in part C, Shigeru Ban should be replaced by an alternative for better cost and maintenance efficiency. In terms of wind technology, further improvisation has to be done to achieve the best outcome possible. At this stage, we have not considered the fact that wind changes its direction overtime. In order to harvest the most of wind energy, numerical data and statistics are necessary to aid the installation of windbelt at its best position.

Moreover, our team also concerned about the placement of windbelt in the design. In the meantime, all windbelts are placed horizontally. In part C, we may be shifting windbelt into different forms of placement, may it be vertically, 45 degree slanted, inverted, double positioning etc. to push its energy harvesting to its optimum condition and refining its aesthetic appearance.

Learning Objectives & Outcomes

Learning Objectives In this studio, there have been a lot of challenges to be overcome. In relation, satisfying each and every learning objective is not an easy task. At the initial point where our team started adapting a new digitalizes designing method also known as parametric computation; it was difficult to develop an ability to generate a variety of design possibilities. In this case, by using Woodbury’s reading as a guide book to perceive the parametric fundamentals, solutions are given on how to get started on case study, parametric algorithm and also fabrication considerations. Choosing the right decision related to algorithm design and parametric modeling was indeed one of the toughest requirements to be satisfied. Besides, Kalay’s reading also provides us with some useful technique such as the ‘search’ process. This however, becomes an advantage for our team to generate better ideas and iterations when comprehend.

Besides, this studio also stress on the understanding of relationships between architecture and its surrounding environment. This objective may not sound crucial but it does contribute a lot into our design process in terms of sustainability and green technology consideration. Moreover, our design satisfies real world construction criteria as we fulfilled the objective which requires us to reflect and study digital fabrication possibilities in depth. Last but not least, by fulfilling all learning objectives, I have developed my very own style of computation design where individuality can be expressed by using computer-aid program. From the algorithm sketches that are shown, a heavy influence of ‘Strip and Folding’ blending with Weaverbird plugin definition express a strong dynamic aesthetics which I believe, would be a design style of mine.

To address the feedback from the interim presentation, one single technique has been selected to focus in depth for the teamâ&#x20AC;&#x2122;s design development in this Part C instead of using several different techniques.

The proposal is a steel lattice structure incorporated with windbelt technology. It is inspired to integrate with wind to generate clean energy and offset demands in Copenhagen.

The parametric technique inspired by electromagnetic field is developed to evolve in relationship to the site and interact with visitors.

Not only acting as an energy generator, the installation aims to fully interact with users to raise their awareness of sustainability. This would be achieved through the vibration of windbelts which produces visual and hearing stimulation.

Windbelt technology has been further tested and refined as a core tectonic element to enhance both aesthetic and functional performance of the design.

Multiple forms were tested to understand how wind patterns perform differently when passing through the structure. Through that, we were able to conclude the most efficient form to capture wind and propose it on site. Form finding is developed through the logic of electromagnetic field which composes of attractors and repellents. Allocating positions of attractor and repellent differently generates outward/inword wrapped-liked structures. Such forms were developed to incoporate windbelt technology as well as evolve in relationship to the site. Upon the wind tunnel analysis, we concluded that Form 1 (outward wrapping structure) is the most efficient form to capture wind energy as it maintains the continuity of wind flow, which is important for windbelt to function.

C2.0 Wind Belt Technology

Windbelt is the non-incremental innovative technology originated by Shawn Frayne associated with his company Humdinger to enhance the social adaption. It was discovered to be a useful and powerful mechanism for catching the wind at scales and costs beyond the reach of conventional wind turbines. It relies on â&#x20AC;&#x2DC;aeroelastic flutterâ&#x20AC;&#x2122;, which uses a tensioned membrane undergoing a flutter oscillation to pull energy from the wind. [2] The theory is based on the electromagnetic induction, which produces electricity across coil in a changing magnetic field. As the membrane vibrates, electricity is produced. [3]

The first prototype does not behave as expected due to it failed in achieving electromagnetic induction. When the pivot point is at the center of both magnet and coil, it permits a rotational movement. In theory, it would not produce electricity as such rotational movement does not alter the magnetic filed when both components move in the same directions at the same time. In order for this windbelt perform correctly, the pivot point (screw) in relation to magnet and coil needs to change. The plane of magnet needs to rotate in 90 degree so that coil movement is able to cut through the magnetic field and enable changes in magnetic field to generate electricity.

The physical model is made at a scale of 1:100, in a rectangular form as same as the site boundary. Constructed in a hybrid process of manual and laser cut fabrication. The physical model conveys the design intent and serves as a proof of the contractibility of the full scale structure.

Additional layer of blutack ontop the foamcore had resolved the issue of stability. However, manually constructing filaments was found to be an ineffective approach. It beame more obvious that fitting all filaments into one spot by hands was difficult at later stage.

This would be achieved through the vibration of windbelts which produces visual and hearing stimulation.

the design is enhanced by computation approach with the same logic of gridshell structure but without being restricted to the form of a traditional gridshell. This enables the structure to stand on its own without additional supports that might affect overall performance of the design. Through numerous refining, this design possesses structural integrity which allows it to exist in real but without sacrificing its aesthetic appearance.

The project is designed through computation approach that expands interdisciplinary integration in its design potential, including material selections, fabrications, forms and abstractions. Hence, dynamicity seen in the design not only served as architectural aesthetics, but also to optimize the harvesting of wind energy.

The 100 mm diameter cold rolled steel tubes were selected for design structure as it has the capability to distribute adequate structural stability. The steel tubes perform a higher state of tensile strength for the dynamic bending form, which directly integrates with renewable wind energy technology- windbelt; to correlating with the installation in its rotation and orientation.

This project is proposed to be built within the south west region of the site for optimizing energy yield from wind. While wind is a dynamic airflow from multiple directions and strengths, the most efficient design form is achieved from the in-depth wind tunnel analysis on site. In addition, the dynamic-strip vortex form that distributed on the site increases the innate capacity to capture wind without blocking the wind passages.

Windbelt is the first non-incremental innovative technology beyond this century-old approach. The technology is originated by Shawn Frayne associated with his company Humdinger to enhance the social adaption. The phenomenon destructive force was discovered to be a useful and powerful mechanism for catching the wind at scales and costs beyond the reach of wind turbines.

The theory is based on electromagnetic induction, which produces electricity across conductor in a changing magnetic field. As the membrane vibrates at a higher frequency, higher voltage is produced.

Another significant quality of this proposal includes the possibility to move from conceptualizing into reality practice. The evocative double-layered structure has been contrived with intersecting joints which were generated by applying the spin force with the opposite direction. Through that,

Windbelt performs at its optimal in the wind speeds of 15mph (7m/s) or higher; hence the technology is appropriate in this context as the average wind of Copenhagen is over 10m/s. A normal size windbelt in the speed of 6m/s wind can generate over 44kWh in a year and the voltage supply of each windbelt is around 3-4V; which is equivalent to the amount of energy allowing a small electronic device to be fully charged. There are over 6,800 windbelts installing in this project, which means over 300,000kW amount of energy will be generated annually. It is equivalent to supply energy consumption for 230 persons or 75 families in Copenhagen per annual. However, as wind flow is dynamic, the structure is difficult to perform at 100% efficiency at all time. In order to highly optimize wind energy generating potential, the integrated design successfully provide opening at different angle to maintain the wind continuity through space. This surpasses the limitations of conventional wind turbines that achieve its maximum efficiency only when wind is captured on certain planar degree. This can be the reason why windbelt device is claimed to be 10-30 times more efficient than a conventional wind turbine. Hence, the project enables the wind flowing through the continuous orientated windbelts from multi-direction, in order to achieve its optimum energy harvesting even during slow wind speed.

Energy production in windbelt installation is made possible to replace conventional wind turbines in the future. The new technology is introduced to harvest relatively larger amount of wind energy with lesser cost and easier construction. The proposal is an innovative pioneer organized for windbelt installation in a delightful way to increase people’s awareness towards new possibilities of renewable energy. The innovative technology in social influence acts as a pioneer of ambitious initiatives to expand wind power towards 2020. Furthermore, the windbelt art installation responds to government incentive in Copenhagen which encouraged public support for wind power by creating a community-owned facility and using local construction method and materials. Thus, the land art project engages visitors through their interactions with site and its potential in popularizing the innovative renewable energy in future through design. Our project spearheads the advance in aesthetical windbelt installation and will also be an interactive art generator parallel to LAGI’s initiatives, ‘Renewable energy can be beautiful.’

Learning Objectives & Outcomes

C5.0 Learning objectives & outcomes

Interrogating the brief requirement would be the primary concern for Architectural Studio: AIR. Only by having a thorough understanding of required criteria would enable our team to incorporate both art and sustainable energy technology as one. Besides, our teamâ&#x20AC;&#x2122;s design has also successfully achieved the aim of interacting users with existing site conditions, not forgetting raising awareness among users.

OBJECTIVE

Developing further understanding of computational design, data analysis and types of programming is achieved by introducing data collection program such as Vassari. Throught that, our team are able to breakthrough earlier limitations in computational design by knowing various attributes of wind factor. In fact, with solid evidence and statistical values, many hypothesizes earlier have been validate, thus giving our team a strong confidence to move forward.

OBJECTIVE

Integrating conceptual design ideas with real contemporary architecture is achieved by further developing our prototype together with the assistance of collected date, it is very clear for our team to know which is the most successful outcome based on real world situation. In this stage, our team successfully obtains optimum efficiency in technology functionally, at the same time, preserving its design aesthetic to its best.

OBJECTIVE

Capabilities for parametric architecture to adapt sustainable technology is met. From every researches and exercises which our team attempted throughout the semester, we learned to picked on our mistakes. Gradually, our team become capable to improvise our parametric design to an extend which windbelt technology can be perform optimally. Being able to improvise and introduce own style of computational techniques into the final design is the major achievement in this subject. Beginning from Seroussi Pavilion to Beijing National Stadium, our team undergoes several bottleneck situation when we attempt to incorporate the best of both architecture into one. After several hardships, our team manages to breakthrough and produces a new outcome which our style is adopted. By using Beijing National Stadium gridshell structure as a stepping stone, new development is achieved in the same logic as gridshell structure without being restricted to the form of a traditional gridshell.

C5.1 Further development

This is the further development of teamâ&#x20AC;&#x2122;s echnique in respond to the feedback from the final crit. To reconsider the design as a piece of artwork, a second layer structure is resolved and added to strengthen the overal aesthetics. The upper part of the existing structure is extended upwards to produce a double layered structure which resolves the design with a performative aspect of different visual aesthetics. In addition, the spaces created between the offseted structures enable visitors to walk through and inbetween the structures. It enhances the feasibility for visitors to interact and engage with the art installation. Beyond just reconsidering the aspect of being an artwork, the modification to the design also addresses the performance and efficiency of windbelt technology. Additional windbelts are installed between offseted members, which are installed in vertical orientations. Through that, the art installation is able to capture wind from multiple directions which resolves the shortcoming of the previous design.
