My name is Cen Xu, a third year undergraduate student at University of Melbourne, majoring in Architecture. I have born and grown up in mainland of China. I am really interested in architecture ever since I was in-spired by the Frank Lloyd Wrights Fallingwater, which I could never image a house can be built partly over the waterfall and harmony with nature in that way, whereas vast majority of buildings I have seen in China were not appropriate designed, which most of them only focus on increasing speed of construction to deal with the rapid growth of population and dense city, ignoring to keep the balances of form, function and environment in a delicate harmony. Thus, my dream is to be an architect to design environmental friendly buildings, as architec-ture can change our way of living.

Before coming to University of Melbourne, I have finished studying in several architectural subjects in the University of Urban Construction in China for two years, and got some year-1 subjects exemption. Therefore, my have not gained much experience with digital design, but used to utilize SketchUp to create 3D models to help integrate design visual-ization process. Although I have some knowledge of digital design by familiar with some impressive practice of masterpiece, parametric design by using Rhino and Grasshopper is still a new intelligent de-signing method to me. However, I am so interested in learning the use of this tool which can allow more complex forms to be created in the architecture design.

Introduction

Much of what we know of institutions, the distribution of power, social relations, cultural values, and everyday life is mediated by

the built environment. Thus, to make architecture is to construct

knowledge, to build vision. To make architecture is to map the

world in some way, to intervene, to signify: it is a political act.

Architecture, then, as discourse, discipline, and form, operates

at the intersection of power, relations of production, culture, and

representation and is instrumental to the construction of our

identities and our differences, to shaping how we know the world.

The form of architecture has no revolutionary changes after the advent of Industrial Revolution, however, with birth of computer as a design tool, architecture as a design practice has became more concerned with its position in the future. The Tonys book of 2008 mentioned our confront-ing affliction is the defuturing condition of unsustainability resulted from rapid growth of popu-lation with limited resources. In a anthropologigcal perspective, design is critical factor which enable us indicate the issue before damage have done, thus Tony believes our future can be secured by design, as a redirective practice able to take the diversity of humanity away from deepening the disaster of unsustainability toward the futuring character of sustain-ability. Design intelligence such as acquire software allowing us to practice, then making contributions and spur to the connections between redirection and futuring, economy and culture.

MEDIA-ICT

The Media-ICT project, designed by team of Cloud 9, Boma, PGI and G3, is located in the 22@Barcelona district at the junction of Carrer Roc Boronat and Carrer Sancho de Avila. The building is designed to be a com-munications hub for businesses and institutions as well as for the media and audio-visual sectors based on the idea of sharing.

According to Jeremy Rifkins theory, buildings embody 35-40% of the climate change issue. In order to increase future possibilities, the Media-ICT brought in ETFE skin to achieve best energy performance reaction, aiming at sus-tainable construction to build a green city, which to cope with the increasing requirements of energy consumption. The function of this new technology is to regulate light and temperature, mainly preventing 114 tons of CO2 per year from breaking away the building and providing a 20% saving on climate control. With the assistance of sensors that gain information from external space, the cushions can inflate, deflate, adjust and become opaque. The skin of this project is active controlled by the network system responding to the environment, hence act as a living component. This result supp -orts the discourse that discussed by Spencer Kelly, urban environment will come alive.

While Rachel Armstrong echoes the idea of living architecture, she explains her new architectural prac-tice where urban characteristic more like an evolv-ing ecosystem than a lifeless machine. In that case, people start to rethink how we approach architecture.

This project represents a exclusive chance to convert Barcelona into a leading platform for innovation by creating the intellectual area, promoting synergies and collaboration among social network in business, scientific and cultural activity to encourage economic and cultural renovation.

In addition, Media-TIC is a parametric architecture, construed applying CAD-CAM digital processes. Analyzing the structure modules by utilizing soft-ware to obtain appropriate result in an efficient way contributes parametric approach to design challenge. Thus the building is not only a cube but a reasonable organized information communication. The facade of this building, compared with traditional industrial buildings, represents digital construction and more contemporary appearance with its free complex pat-tern.

The golf club house Haesley Nine Bridges de-signed by Shigeru Ban Architects $ KACI Interna-tional, situated in Yeoju in Gyeonggi Province. It offers the best condition of facilities and services owing to the established the worlds first 18 holes SubAir & Hydronics system. Adopting 18-hole innovation solution of wooden column timber structure is not only for its unique aesthetic as well as for the realization of the environmental friendly aiming at sustainability. Timber structure, as one of the most sustainable construction material which is an example of the stunning design possibilities, was maximizing used in this project to achieve green future design. Compared with concrete and steel construction, the amount of CO2 conducted by timber construction is obvious less. As a result, the development of this new structural pattern will encourage architects, engineers and clients to ap-ply the sustainable construction concepts for the future.

The building consist of the unique tree-like hexagon grid shell, reaching to the height of three stories, with an ecological and naturally ventilated concept of the hexagon pattern, is inspired by a Korean tra-ditional summertime pillow which named bamboo wife, while the fire-resistant roof and columns are exposed in the internal space.

According to Tony (2008), design should be intel-ligence to determine the construction approach, whereas Schumacher advanced design tool and cutting machine technology have been utilized by Shigeru Ban Architects which enable to figure out the most efficient structural form and minimize the assembly process and quantity of timber used. Moreover, the clubhouse is a 16,000-squaremeter facility that serves for clients somehow communi-cation will occur. Patrik reinforces the systems of communications by explain that system as autono-mous itself can generate its own components and structures within the ongoing flow of communica-tion.

Computation is redefining the practice of architec-ture. Architects are developing digital tools that cre-ate opportunities in design process, fabrication and construction. said by Brady (2013).

Parametric design is a new approach of intelligently design process of 21st century based on connec-tions and principles utilizing computer, which is automatically set up in software thus can easily and quickly manipulate and generate multiple iterations of pattern in three-dimensions. Therefore, computa-tional thinking is engaged in computation to satisfy our need.

Computational thinking is the thought processes involved in formulating problems and their solutions so that the solutions are represented in a form that can be effectively carried out by an information-processing agent.

The design of Museo Soumaya in Mexico, adopted complex computational technologies to accept the challenge of creation of culture collaboration with 3D model being analyzed throughout the design pro-cess. The challenge of this practice was the facade structure was already chosed, so the possibility of modification and rationalization is limited. In order to solve the issues occurred on the curvature surface, over 16,000 unique hexagonal panels should be pro-

duced, which cause a huge cost problem. It is a meth-od of computerization, which entities or processes that are already conceptualized in the designers mind are entered, manipulated, or stored on a computer system. As a result, the power of new use of compu-tational technique should be aware and utilized during the design process to assist in problem resolving. In this case, parametric modeling methods cultivated by Gehry Technologies were applied to produce the families, allowing mechanical system adjust the panel sizes to achieve idea results. Consequently, the deci-sions could be made quickly in real time by the archi-tects at the important moments of the construction. A somewhat similar idea is presented by Jan Cuny, Larry Snyder, and Jeannette Wing by stating computational thinking further means making possibility to address problems in a larger scale which could not be solved by traditional methods and apply the new computa-tional approaches to conquer in any area.

Another example of computation is a practice that flying robots programmed assembled architecture by Gramazio & Kohler and Raffaello DAndrea. The mobile helicopters were set up to lift, transport and assemble 1500 polystyrene foam bricks to conduct 3.5-meter heigh structure. The intent of this struc-ture is to create a new way of building construction that robots can be modeled to build the construction without physical labor in the future. This pioneer-ing method on dynamic material composition and machine feature addressed ground-breaking au-tonomous systems design and algorithms by fully exploring the potential of computational thinking. The innovation of the practice with full understanding of the data enables rational acoustics and knowledge-based, which intelligent design system that can actually propose design solutions for appraisal and further development by human designers.

Within the information age, the term design method now goes to parametric iteration lead-ing the word composition served to suggest the process of design architecture. To be speci-fied, composition brought into full function at the moment from the Ecole des Arts of Jacques-Francois Blondel, through the long period of the Ecole des Beaux-Arts and remained in the Modern Movement to the middle of 20th cen-tury. Hence, composition was a fundamentally French idea but spread to the world following. In Lucans writing, composition is antecedent to style, thus the concept of composition during that time was intimately limited to the theory of architecture itself. Shifting from composition to generation emerged by exploring digital design method.After this, algorithm as one interpreta-tion of the computational hypothesis of architec-ture represents a process of computation that allow the statement transitions to be proba

bilistic, which could create various para-metric modelling that we can not image, only creatively generated by computa-tion breaking our boundary of imagina-tion. When architects have a sufficient understanding of algorithmic concepts, when we no longer need to discuss the digital as something different, then com-putation can become a true method of design for architecture.

Both examples of Khan Sharyr Enter-tainment Centerand Beijing interna-tional Airport by Foster Partners, clearly espress computation can fully inter-grated into the practice and actual desifn process.

In conclusion, conceptualisation derived from parametric approach can solve the issue countered effectively and quickly during design pro-cess, conceptual changes instigated by computation existing data. This new innovative approach implement the design idea in a more ratio-nal and reasonable way. It is significant as it not only a fundamental parameter in the creation of architectural form but also to achieve the sustainable future.

This innovative method can assist us deal with more complex situation in design process. By learning this, my past design can be improved by exam those issue occurred using computation to generate a cre-ative result.

PART B. CRETERIA DESIGN

Shapes are diagrams of forces

--DArcy Thompson

Our group was decided to focus on strip sys-tem, as we thought this system as a genera-tive design practice is one representative of parametric design, and we were so impressed by the example of Seroussi Pavilion in strip system, which pushing the boundaries of the design through using digital design tools cre-ating something so interesting that we may not even imagine. With witnessing the rapid growth of parametric design, designers and architects start to interest in applying their new design intents in the digital tools and strive for a new line of form generation through utiliza-tion of parametric design approaches, bio-informed structures and material systems, etc. Therefore, aspire to new more potentials and generally new methods of design and fabrica-tion is in the front line of us. Strip morphologies as a light weight material system for design will be our central topic to explore the possibilities of computational design.

According to architect Kai Strehlke, methods of computation are not technologies that we were trying to make something with it, but more concentrate on design intent and architectural

and concept. Thus, during the design process, it is important that we have got our concepts at the beginning, and then it can be very fast in program-ming by utilizing the primary computational design tools, such as in our case by exploring Grasshop-per. The potential of computer is huge, as digital design integrate various techniques from funda-mental to progressive with no personal preferenc-es. In his Digital Technology Group at Herzog & de Meuron, every project conceptually represents by itself, as each specific tool will be write for the idea of design, so there are no styles and restrictions in the design process.

Computational approach enables to establish virtu-al model and fabricate dynamic and unpredictable structures, by constantly transforming and updating with its contextual affects.

The following precedents examine the application of computation to generate strips structure at differ-ent scales which lead us to think about the poten-tials of this system and try to develop it by Grass-hopper by ourselves.

The Archipelago Pavilion is a self-contained sys-tem of connections of seating structures which occupied the courtyard in frond of the Museum. The structure itself is intent to shade seatings inside and builds shaded spaces around it. This pavilion was parametrically designed in Grass-hopper and Rhino constructed from 133 pieces 2 mm thick laser-cut steel sheets which join together with joints and bolts. Obviously, the installation would not be achieved without digital fabrication and engineering techniques where accuracy is needed to generate the steel pieces to form the structure, exploring translation from computer generated design into built architec-

puter generated design into built architectural objects through digital fabrication. Due to the character of steel, visitors can lie comfortably on the surface inside the pavilion.

The intricate web of spaces resembles clus-ters of small islands in an archipelago. The perforation on the roof spreads out an organic pattern resembling the one you would see from a tree in the forest. This design idea inspired us in the following design process to frame our design to a somehow similar clusters of atolls in a massive mazy pavilion,which will be dis-cussed later.

Loop3by Co-de-iT

Mathematics provides an underlying layer for the description of realitys inner complexity in terms of computation as well as the tools to enhance and intensify research and expres-sion, elegantly and seamlessly linking science, art, economy, philosophy and other disciplines, merging them into force fields of a unified yet topographically differentiated territory. Architects relentlessly explore this territory ever since, us-ing mathematics as a privileged tool for tracing systematic paths as well as enhancing their expressive language.

As a means of aesthetic tool, mathematical trigonometric features were applied in the in-stallation of this self-standing volume, through exploring parametric design tools. Without the parametric design, the outcomes of experiment inrationality in complex shapes that merges user spatial interaction, curvature as a struc-tural and expressive strategy and forms as a sorting device to deploy functions can not be achieved.

If mechanical forces can be distinguished, it is not because living matter exceeds mechanical processes, but mechanisms are not sufficient to be machines. A mecha-nism if faulty not for being too artificial to account for living matter, but for not being mechanical enough, for not being adequately machined

Seroussi Pavilionby Biothing

The Seroussi Pavilion by Biothing was a practice based on the movement of electro-magnetic fields, leading to a series of algorithms upon its potentials. Although more like biologic piece of art rather than an pavilion, it represents the computation-al process of form finding integrated with the space. To begin with electro-magnetic fields shapes, the plan frame out the at-traction-repulsion movements generating organic interesting patterns.The design parameters including topographical adap-tions that response to the various environ-mental context. The series of algorithms present the possibility of digital design.

B.4. Technique: Development

At the beginning, we have tried to use the tech-niques we learned and practiced in case study 1.0 to play around the linearity, but we found it was difficult to get a distinguished results. After several algorithm experiments, we come to a conclusion that the first explorations of individual unit of vector lines were not fitted to our design creteria, especially in terms of resultant form which was scattered and meaningless.

First Exploration

The iterations were only repeating the basic forms in a spatial way without so many chang-es. Thus we attempted to make it in a cluster, as shown in the first picture. However, it was still not successfil as each unit was separated which dose not have a coherent structure and was not fast construtible that did not take the advantages of parametric design.

We started our second exploration by trying another script which generate the conterminous sur-

Althougn the first exploration was failed, we got severl feedbacks that improves our further explor-ing and good for our design intent.

Second Exploration

Second Exploration

We started our second exploration by trying another script which generate the conterminous sur-faces as a whole and introduced clusters in Grasshopper, which create a massive algorithm. Moreover, we got more choise of methods to fabricate the project.

Second Exploration

In order to achieve different interesting results in a larger scale, we developed our definitions into somehow similar to Tesselation by connectting offseted curves as a whole structure rather than separated small units, and then ralaxed surfaces to obtain smooth surfaces. The following itera-tions show the exploration of its potentials.

B.5. Technique: Propotypes

In this stage, we started to consider physical experiments in combination with digital algo-rithms.

The outcomes of our first exploration gener-ated a scattered disconnected bare frames resembled inflatable tent clusters obtain no logic of joint or material distribution through computation.

Our original design intent is utilizing light weight material which called carbon fibre reinforced resin pole as the structure of pavil-ion hidden behind a membrane which creat-ing the surface and interior spaces as well as enhancing the reaction of wind force, resulted in the vibration of carbon fibre pole generat-ing the energy from the wind source. We were firstly trying to make the physical model by our hands, and looking for a light weight elas-tic material that could be bended to our ideal forms. The first model was made to examine what the inside and outside space would be like by this shape, the second model was about to imitated the single unit form of clus-ter, and the third one was a experiment how

Thanks to the membranes characters, a tensile structure will be constructed. In order to know the realitic possibility of this algorithm, we also tried to run Kangaroo to simulate its dynamically movements once tension was put on the structure.

Next step, without thinking about what materi-als could be used in our project, materialisation like fabrication and assembly is also very criti-cal, thus, several stuff such as joints or struc-ture components should be carefully designed.In our project, it is important to get each pole to be connected and positioned stabled at the bottom. Therefore, we were thinking about use base plate at the poles bottom bolted to the underneath ground which is constructed similar to the column construction. Then in order to make sure a stable under portion of the struc-ture, a fabricated strip may need to hold all the poles together for each web. Furthermore, in terms of top connected structure, a joint was design to achieve connection where junctions occur between two members. Both strips and joints can be generated in Grasshopper .

Selection Criteria1. Consist of organic form that has the ability to attract visitors to the site.

2. With functions like sitting or lying in it and iterations with visitor

3. Capture the wind force to generate the electricity

4. Should be constructible with appropri-ate scale

5. Familiar with the site context

Eletricity Generation

B.6. Technique: Prototypes

The Windstalk project sonsists of 1203 carbon fibre reinforced resin poles coming out of Herseys Kisses-like bases, due to its slender and tenuous feature. This example use for reference as it will produce power by wind blows with somehow strip like structure.

Each stalk is comprised of a stack of piezoelectric ceramic discs that are in-terspersed with electrodes. As the stalks sway and bend, the discs are com-pressedThe generator takes the current and turns it into electricity.

The generator converts the kinetic energy of the swaying poles into electri-cal energy by way of an array of cur-rent generating shock absorbers, which convert energy produced by the forced movement of fluid through the shock absorber cylinders.

By looking this example, our group were thinking this technique could be introduced to our design to satisfy the requirements that generation electricity from wind force. Furthermore, we can make this materials sway or producing

B.6. Technique: Proposal

The primary design concept is to create a pavilion that can capture energy from wind and convert it into electricity as well as visitors interaction with its aesthetics features. After a series progress of matrix development, one interesting model which fulfils our design criteria has been picked up. The structure of this pavilion should be constructible, so that we were thinking set a solid construction like columns on the edge of the pavilion and insert the carbon fibre reinforced resin pole with energy generator device in the middle of structure, and then wrap and connect the pole with net.The flexible character of nets allows it connected one another on counterpoints as tensile surfaces of internal pavilion. Visitors are attracted to sitting, lying or even climbing on the nets to explore interior space. Meanwhile, the produced vibration transfer to carbon fibre pole that generate the energy. It encourages visitors to interact with the pavilion and generates the electricity at the same time. In order to take advantages of both energy generation way from wind source and human interaction, specific several columns will be built higher to get strong wind source and interior structure will use net to wrap around the columns inside the pavilion.

B.7. learning Objectives and Outcoms

FEEDBACK

After the interim presentation, carbon fibre reinforced resin pole as the main material and structure of our design was not well organized. According to Alexanders comment, the struc-ture will be too light that cannot stay in the site, and we were suggested to think about make every separated unit into a one structure that can be stable. It is very important to notice that the structure should be constructible which is also mentioned by Can. Therefore, connecting in our structure is significant as it could pre-vent from unstable as a whole system. Before the presentation, we got too many ideas that putting in one object and kind of missing our primary element to take the advantage of the parametric design and its fabrication tech-niques. Therefore, we decided to clean up all our original design intent and more focus on one primary factor.

However, our parametric model was not con-vincing due to our limited Grasshopper skills as well as our idea were not clear represented in the presentation. Our tutor Chan had re-directed us to review different systems and as-sist us in computation that help us to achieve our design.

Upon reflecting guest tutors comment, we again look back into our research on other region such as projects about system of large geometric inflated objects, minimal surface projects and application of materials which may give some design ideas as well as provid-ing more potentials of our proposal.

LEARING OBJECTIVES

Through this design process, I have not only developed my skills in digital design tech-niques but also learned from the design pro-cess itself. Begin with researching precedents and literature to allow me familiar with the tech-niques, secondly, develop my ability to make a proposal in a group work compared with indi-vidual work, communication with each group member and attributions from each one is important. Thirdly, it also develops our ability to think logically and present by using diagrams and iterations, setting the selection criteria and then we can achieve a successful one.Last but not least, this process greatly devel-ops my foundational understandings of com-putation as well as computational techniques. By watching online videos and trying to under-stand the complex definitions from website, I could use parametric design to figure out future challenges.

PART C. DERAILED DESIGN

FEEDBACK FROM INTERIM PRESENTATION

Moreover, since the membrane is not a core element in our pavilion and the flexibility character of membrane is hard to retain its equilibrium and shape upon our structure, as well as there is not much potentials in innovative design, we were thinking about the feasibility to using membrane wrapping around the structure and may use other materials instead, which will be also discuss later.

According to guest tutors suggestions, the form of our design is not going to work in the big scale on site, thus we decided to cut off the half bottom structure of the pavilion and will further develop the form finding process, utilizing parametric tool to serve our concept.

The feedback from interim presentation was very important which made us constantly thinking about what we have done, what we could be doing our proposal better and questioning ourself.

Will the carbon fibre reinforced resin pole as the main material and structure work in our design? As well as the membrane, how can we attach the membrane in the stick like structure? Will the scale we used suit for our pavilion? How can we take the advantage of parametric design and technology in our pro-posal? While we started to finalized our pro-posal, all these problems came up. At this stage, we need to solve the problems rather than keep adding ideas on our proposal.

The first thing need to be solved is energy generation. As the way we used to generate energy is not working, our group changed to analysis if we could introduce biomass in our pavilion, which may bring innovative ideas and will be further discussed in the following.

C.1. Design Concept

BIOMASS

Biomass is considered a sustainable energy resource because it is a product of organic processes which naturally regenerated at a rapid cycle (as opposed to fossil fuel energy sources which take millions of years of form naturally).

Biomass can be combusted directly as a solid fuel or converted to liquid or gas biofu-els. Thees biofuels can be used in either a combustion engine (conversion to mechani-cal energy) or in a fuel cell (conversion to electrical energy).

As our aim is to generate renewable energy from biomass with minimal surface structure, successfully incorporating biomass elements as a part of the installation is an interest-ing concept as it will generate energy by itself from the cultivated plants on site. Thus, the planting system on site need to be carefully considered, which also act as landscape of the site segregated pathways at the same time to create different space.

After exploration, a specific of plants have been chosen, which is wheat that can be grown well on site, working with particular environmental conditions and microclimate associated with sun, water and wind.

Since the alcohol biofuels like ethanol are produced through the fermentation of sugars from wheat, the generation process list below.

low crop density High crop density, srandard rows

High crop density, uniform pattern

Reception & Storage of grain

Milling Mashing, Cooking & Liquefaction

Fermentation & Cip system

Distillation

Dehydration

Storage Ethanol

However, installation of these machines need to be considered, as we do not want visitors observe those machines but have an idea of how we generate the ethanol. Thanks to the analysis of our previous structure, we think we can take the advantage of its hollow col-umns by installing all machines in the structure.

Meanwhile, another advantage of hollow- column structure is that soil can be filled which providing enough space, absorbing and keeping rain water to grow wheat.

FORM FINDING & OPTIMIZATION

Previous proposal

Our basic form of previous proposal was inspired from Copenhagens city plan--the finger plan. We tried to distribute points along the finger plan, as well as we con-bine the traffic density to set the density of points.

We set up five curves to create pathways that visitors may tend to walk, as well as the more open pathways will guide visitors walking direction.

However, the walking space still flexible as there still large space between each col-umn.

As the pavilion is at large scale, the light in the pacilion need to be considered, thus the opendings carried out along the path-way allow the sunlight penestrate.

To ignite the birth of our design process, we begin with the basic experiments involves the organisation of the voronoi pattern. The purpose was to devise a cellular division strategy that is derive from points.

Left is our previous basic form for proposal, however, it was not well-received. We tried to set points that represents area that visitors may more tend to walk, but after we have done the digital model, we found where people have more walking tendency where the density of columns will be higher, which was totally different with what we thought.

The outcomes in cellular patterns from voronoi that divide space among points, giving us flexibility of controlling program and circulation.Therefore, voronoi as a thchnique that serve for our concept generate the basic form of our design.

Belows are the experiments in different voronoi pattern.

SUBDIVIDING SPACE

Upon the site analysis, we thought the site could be divided into 4 zones according their functions and views. A water taxi in blue zone may influence on the circulation. The green zone close to water could have a good view of opposite harbor. The yellow zone is the main entrance of this site. And the orange zone includes the most unwanted neighbouring factories views.

And the orange zone includes the most unwanted neighbouring factories views.

The blue lines indicate the circulation of visotors which need to be taken into ac-count.

Although our main design concept is to cre-ate a biomass educational park, after we review the brief and site photos, we started to think about how we could develop our proposal associate with site context.

First of all, we do not want our structure like something directly stick on the site, thus, in order to make it be harmonious with the environment, we utilize the smooth cellular voronoi rather than other regular shapes.

As Refshaleoen used to be a shipyard, we were thinking if we could make our project as an iconic structure in the harbor. Such as using fluid lines and organic shapes that relate to surrounding environment, inspir-

ing us to make a float deck upon the site. Therefore, our intention is to make the structure raised off the ground naturally like a biostructure, creating public space not only underneath but also upon the structure.

One smooth cellular form was picked up which is optimised for proper density and its fluidity geometry that we wanted.

The form was finally diveided by three function zones which analysis before, while we used fluidily lines to region the boundary, after several experiments, an intresting form was optimised.

C.2. Tectonic Elements

Firstly, we were kept testing our prototype of the membrane after interim presentation. The issue was how can we keep a tensile mem-brane paste on the surface of our structure model.

We only can fix it at several points ang give it some pull stress, but can the shape of the membrane is out of our control.

Thus we tried to use the food membrane which is without tensile character to wrap around the structure. Althoung it worked and was not performed bad, it did not include any paramatric strategy, which lost the meaning.

Moreover, the structure itself did not really need to be related to membrane. After care-fully consideration, as well as we finalize our proposal, a more firm material will be more suitable for our structure.

Digital adjustment

Next, we started to test our new proposal elements, such as columns and function rooms which is like a little log cabin on the upper level. As our proposal is to make a concrete bio-structure float on site, the major issue is how we could pour a smooth free-curved concrete surfaces.

After research, a hybrid construction including timber framwork, steel panels and concrete is ideal for our proposal, thus we think the fabricated wooden framwork is essential that should be accurate to make the doubly curved concrete surfaces.

Inorder to make the upper strucutre keep the continuity and harmony with our design, we built up a somehow waffle structure like little log cabin digital dodel. By changing the density of components, different facade will be creat. As well as we found the facade also provide shadings for internal space and creat more private area inside.

When think about the joint, we use fin like waffle structure that they can fix together without any other joint.

After finalizing digital model, all elements were ready to be sent to Fablab.

C.3. Final Model

C.4. Additional LAGI Brief Requirements

Our design intent is to built up a biostructure park that can generate energy from self cal-tivated wheat on site. To be innovated, we do not plants wheat directly on the ground, but making a floating fluid deck uppon the structure, which supported by doubly curve cloumns that create an open underneath area, thus attract visitors to experence this space.

In order to achieve the smooth concrete surface, the accurate timber support and steel panel were developed from digital tools, which make building components into the constructive geometry.

Exhibition panels on the columns could show the process of manufacture of bio-fuel with educational function. Moreover, the underneath space can also act as museum for special event of exhibition.

The smooth conrete curved columns provide a continues large open space under-neath.

The project is also detail designed, such as a pavilion was designed to provide multi-functions as well as for visitors relaxing. The waffle structure provides vertical and horizontal shading, while it does not discourage visitors from observing external views.

Skylight is also designed for each cluster to offer enough light for underneath space, as well as to provide different spacial perception. The small cluster designed for water taxi terminal allows visitors enjoying the environment and views while waitting.

Technology

The major technology in our site is produce ethanol from raw materials such as wheat we cultivated on the site. Due to the structure of hollow columns, we fully utilized the space for hiden every machines and servises to achieve the aesthetic objective. Following research, wheat will go through a series bio-mass process of milling, mashing, fermentation, distillation and degy-dration, and ultimately converted into ethanol for cars or electricity generation.

More efforts have been putting on the research, with todays technol-ogy, one bushel of wheat yields 2.8 gallons of ethanol-and the number continues to increse.

Moreover, an comprehensive waf-fle timeber structure and steel pan-els were also utilized for achieve the smooth curved concrete on our site.

Dimensions

Due to the massive of this project, the ceilling of ground level is about 6 meters high while the totally proj-ect is about 12.7 meters high.

Major material in our project is con-crete which form our main column structures and upper concrete slab for deck.

Timber was used to form the struc-ture and Local Cypress Pine was used to construct the upper level pavilions.

Glasses were utilized for protection and openings.

Elevators are designed for con-necting upper floor and ground floor circulation.

Dimensions Environmental Impact

Athough our intention is to create a park that attract visotors inter-action, eco-friendly park not only plant the massive wheat which is good for environment but also can be converted into ethanol.

Thus, ethanol as a renewable energy is blended in a percentage with gasoline to create a finished motor fuel which is much cleaner burning fuel that gasoline, offering a significant reduction in carbon monoxide and gydrocarbon tail-pipe emissions. Moreover, ethanol provided for site transportation and neighbouring factory can improve the air quality.

As well as our park with educa-tional intention can guide people tend to use renewable energy for protecting our environment.

C.5. Learning Objectives and Outcomes

After the final presentation, our effort in exploring interior space of our pa-vilion was not well-received by guest tutors, however, they gave us sev-eral valuable suggestions resulted in our new finalized proposal using parametric tools to explore its poten-tial. After large amount of time spent on testing, our final form was opti-mized and developed well into de-tails step by step. During the design process, we have learnt refine and finalize our design is significant that it is a optimization process of what we have got and try to deal with the problems and issues we have met rather than picking up something we believe it is good and add it in our proposal. Thus, I also have learnt the how to simulate digital model to solve the problems for fabrication

From this studio, my knowledge of computation design have totally changed, it opened my eyes on new field of architecture can be, as previ-ously I only thought computation was a tool that help us drawing or built up models, which just like the way we used Auto CAD and Rhino before similar to hand drawing but more intelligent. However, I now learnt how to use grasshopper to manipulate de-sign by utilizing parametric modelling or event solve the details of fabraca-tion and assemblies. Throughout this project, althougn we encountered numbers of problems that make us unable to achieve an innovative idea, we get more and more skilled with solving problems and testing tectonic elements.

The parametric design has encour-age me to explore more iterations that help us to achieve a better result rather than having a final form of our design in mind without any testing. As well as parametric design allow us to achieve more complex form.
