INTRODUCTION Henry Chhen
Gday, I’m a third year architecture student studying at the University of Melbourne. Love studying here. Beautiful city, great building, and the people are unbelievably friendly. The reason I chose to study architecture is due to lego. As a child I loved playing with lego, and often I would try to create the biggest thing possible. Now all grown up, I still have that burning desire for big, and the biggest thing that can be made are obviously buildings. Aside from fulfilling an egotistic desire, I also dream of building my own house. A house that serves my needs and reflect my characteristics. And to have something to point to and say to my friends and family, ‘I built that’. Once I achieve that, life would be good. I am looking forward to studying Studio Air. I heard a lot about the great uses of grasshopper, so I can’t want to test it out and create something mind bogging complex. With computers being one of my main hobbies, the subject is right up my ally. I love playing with Rhino, but I am rather bounded by the skills I have, thus can mainly create rather simple objects. Hopefully once I learn grasshopper, the chains will break. Enjoy your read.

PAST COMPETITION ENTRY ART WIND ENERGY UNIT: ANA PALLARES & JONATHAN RULE
For the 2012 Land Art Generator initiative, participants were asked to create an art installation for Freshkills Park in New York City. The art installation not only had to be aesthetically pleasing, but also had to serve a functional means of producing either green renewable energy or resources. Therefore the design must not have any CO2 emissions, and have the capability of storing or transmitting the energy/ resources it creates. From the list of the 2012 applications, the Art Wind Energy Unit was chosen to be reviewed, as it presented to be the most realistic and reasonable choice. It’s design was not over dramatic, and it prosed functional reasoning to how it generated energy, as opposed to its fellow rivals. Firstly, the Art Wind Energy Unit generate energy through the means of both wind and solar energy. Through the envelope, ‘the conical form and open slits concentrate the wind, increasing wind speed of up to 1.4x allowing for more energy to be generated’1.
Fig 1: 3D diagram of the Art Wind Energy Unit
Inside that form are a series of VAWT wind spire wind turbines. Chosen for their light weight design, silent nature, and ability to be grouped, these turbines generate energy from the redirected wind imposed by the conical form. The envelope acts as a physical barrier, preventing wildlife from entering, and also serves as a means of hosting solar ivy. From these solar ivy, addition energy is generate as the sun is cast onto the installation, whilst at the same time, providing shade for the users. With both wind and sun energy, the AWE is able to generate 29,000 kWh/year The unit seems to compliment well with the site, but the only concern is that since captures wind, wouldn’t the wind is disruptive to the users who are using the unit as shade? And since it focuses wind thorugh a narrow tunnel, would be it nosiy? Therefore this unit may actually be disuptive to teh site.

PAST COMPETITION ENTRY BIO REACTIONS: JOAQUIN IPRINCE LOPEZ
Fig 5: Bio reactions
Consist of 3 circuits of photo bioreactors, which are 3 circuits placed in a labyrinth manner around the park. The justification behind having 3 main circuit pipes is to allow the controlling and testing of various algae types, and condition of environment to maximise algae growth In addition to serving as a host for the algae growth, the pipes also have

an interactive mean. People can sit or walk between the pipes, and the children can use the pipes as playground equipment. At night, led are used to light up the pipes. Due to a large range of factors such as algae types, growth stage and density, it produces a wide spectrum of green colours within the pipes, causing a rather spectacular
and inserting night display. Resources for algae growth are taken from local sources. Water is taken from nearby lakes and rivers. C02 is extracted from the local landfill, and waste water which contains the nutrients for algae growth, is taken from local buildings1. By recycling these by-products of local structures, the growth of algae seems highly justifi-

a strong message about using algae as green fuel.
The project has done great research in looking for the optimal algae species, and finding ways to provided it, but sadly made a design that lacked in design. It simple looks like a complex system of pipes in which people pass through. It doesnâ&#x20AC;&#x2122;t look appealing at all, nor does it seem to convey
Thereâ&#x20AC;&#x2122;s nothing really interactive and unique about these piping arrangements, thus might not be greatly appreciated by the user.

Personally, this design seems to be a waste of space. With such a large area, they should have divided lay-
outs that took advantage of the big space, exposing more algae to the sun, thus more algae being produced. One design feature that could be considered is perhaps a algae green roof that grows algae, used as a shelter, and the light going through might get a light green hue, thus making the space more interesting.

WIND TURBINE BRIDGE: FRANCESCO COLAROSSI, GIOVANNA SARACINO AND LUISA SARACINO
This design re purpose abandoned viaduct into green energy generating bridges. Using the space below the viaduct, large amounts of wind turbines are added underneath the structure, to generate energy as the wind passes through, Looking very futuristic and sleek, it was purposed by the design team that 26 wind turbines can be added, which can produce a total of 36 million kilowatts of energy a year1. Solar cells will be installed on top to produce an additional 11.2 million kw/h2. In addition, the large space will also serve as a communal ground. Parks, promenade and greenhouses are installed on top, serving as a resting pit stop for the drivers, and be used as a farmers market.
Secondly, adding wind turbines increases the lateral loads imposed on the bridge, as the turbines resist the wind pushing it in order to generate power. The design shows no form of lateral support to resist these forces. It only has long columns, hence the bridge is has a high probably to falling down under medium to high wind. The designers did not address this problem Lastly, holding public spaces on the bridge is not an area of attraction. People will not simply drive to a busy bridge to go to the market. Making it a rest stop seems understandable, but it cannot serve as a market.
While the design looks very cool and slick, it does not have a very practical use. It is the sort of design where only the looks and ideas were considered, but the practicalities were ignored. For instance, the wind turbines are fixed in their position thus cannot attain wind from other directions.

BIQ: ARUP, SSC STRATEGIC SCIENCE CONSULTANTS AND SPLITTERWERK ARCHITECTS
The BIQ is a carbon neutral apartment, and is the worldâ&#x20AC;&#x2122;s first building to have a bioreactor facade. Not only does the facade serve as shade, insulation and sound insulation, but is used to generate algae growth. To grow algae, the facades consist of an arrangement of hollow rectangular panels, which hold water. CO2 and nutrients are regular pumped into the panels, and the water warmed to optimal temperatures by the sun. Hence with the perfect breeding habit, the algae rapidly grows in the panels, and once it reaches the optimal mass, it gets collected, converted to biomass, and then used to generate electricity for the building. The usage of algae as the source of power is what gives this building the title of being carbon neutral. Aside from serving as the breeding ground for algae, the warm waters from the panels are also use to warm up the hot water system of the building, or cached in the ground using borehole heat exchangers1. CO2 is extracted from the flue gas, which overall reduces the CO2 emissions from the building2. Therefore, aside from nutrients, the building itself can sustain algae growth.
This building is a true inspiration. Aside from the provision of nutrients, it is nearly self supporting. For this assignments, we can perhaps design an housing estate/ apartments that follow the same principles in regards to the facade. However we can take in the extra step by using the water from the nearby river or the waste water, to provide the nutrients, thus becoming entirely self sustaining. With this, the building can be appreciated for not only its looks, but its proper functionality as well. In addition the facade does have a few aesthetic appeals to it. With the algae in the glass panel, I imagine it to create a beautiful light green hue when the sun is cast against it. The issue is that the building is too green, and that since it has green walls, the light green light would not be as contrasted as opposed to a white wall. (I would take advantage of the green light rather than hide it)

RENEWABLE ENERGY ALGAE BIOFUEL
Fig 13:Algae biofuel farm: trough
Algae biofuel is an alternative to fossil fuel, using algae as the source of energy. Algae releases CO2 as it burns, but unlike fossil fuel, the CO2 was taken from the atmosphere as it grew, thus does not increase/nor decrease the amount of CO2 in the atmosphere. Algae is extremely flexible as it can grow on various water sources, fresh water, salt water and even wastewater, with no impact on the water source. In addition, since it is biodegradable, even if there is a spill, it will have no impact on the environment.
as changing ph levels, temperature, exposure to sun and wave movements. Algae is the better option to the other biofuel alternatives. It can produce 300 times more oil than crops such as palms or soybeans, and it requires less overall area to grow1. In addition, algae has a harvesting cycle of 1-10 days, and can double its mass in a single day, proving to be far more efficient as opposed to the biofuel alternatives2.
The only resources required to grow algae are water, nutrients and sunlight. The required nutrients are nitrogen, phosphorus and potassium. Being said, its best to grow algae in a controlled environment, as growing it out in sea has various effects that could alternate its growth, such

RENEWABLE ENERGY MAGNETIC FLUX
It is the fundamental behind majority of generates used to produce energy such as wind turbines, dams and even nuclear power. Magnetic flux refers to a change in a magnetic field, and it is from this change that produces electricity. When a magnet goes through a wire, it induces its magnetic field onto that wire which produces a current, referred as an electromagnetic induction. However that field needs to be constantly changing, either in strength or direction or no magnetic field in order to keep producing electricity. If the magnet remains stationary in front of a wire, it only produces electricity the moment the wire is in the magnetic field. After that no power is produce, as the field isnâ&#x20AC;&#x2122;t changing, it remains constant. Therefore the magnet needs to continuously pass through the wire to make power. The faster it passes through the wire, the more electrify it produces. In addition, the greater the strength of the magnetic also means more power.
This is represented by this simple equation
Induced current is proportional to the rate of change of flux. We see this basic application in application electric power generators. The two basic ways are: Magnetics are the end of the rotating shaft of the generation. Surround but not touching the magnets, are coils of wires. A coil at the end of the shaft, and this time surrounded by magnets. From this, looking at various means of kinetic, gravitational or mechanical energy can be used in conjunction with magnetic flux to produce electricity.

RENEWABLE ENERGY SOLAR HEAT GAIN
Solar heat gain is the collection of heat generated by the sun to produce power. The general way of collecting solar heat is to have an large array of mirrors all reflecting the light to a central point. This central point either contains water or molten salt which heats up and boils, thus spinning the turbines and generating electricity.
With solar heat, it does pose two problems. First being that it requires a lot of land to efficiently capture and reflect the sun to the desirable temperature. Secondly, the focused light can be hazardous to both aeroplanes and birds. Birds found charred to death have be found around the Ivanpah Solar Power Facility.
Molten salt is an energy storage alternate to water. With the heat energy it retains from the sun, the molten salt holds it in for a very long time. This energy storage is extremely beneficial as the retained heat can be used to make power during the night. Thus at daytime, with general solar heat plants, the sun is both used to generate power, and recharge the molten salt to be used at night time. The main requirements of molten salt is that it needs to be heated up to 800 degrees1, which is feasible since the towers (the central point of light focus) from solar power factories can reach to over 1000 degrees from the focused light. Sea salt can be used as a substance for molten salt, which is an advantage due to the river being near by.
Considerations need to be taken to account on the design of the mirrors, and how the mirrors track the sun. An automated process needs to be plan that can effectively track the suns direction, and ensure that all mirrors focus their reflections on the central tower.

A.2 DESIGN COMPUTATION Computation is a massive benefactor to the designing world. The tools and flexibility, completely transformed the way we design, how we design, and how we think about design. With computers, designer needs to think more logically and mathematically. With this, they can apply rules to the software program to generate various design idea. Thus as opposed to the tradition means of pen and paper, and physically drawing what the design product looks like, the action can also be mimicked in computation, or designers can apply a series of formulas to generate the same resultant. What computation bought were designs too complex for our mind to comprehend without aid, and details take would take years to sketch by hand. The bringing of the digital age transcribes the skills bounded by pen and paper. With this architecture went beyond designing through composition, and looked into design via generation. It is the creation of design unshackled by limitations held by the world before digitalization. Aside from a new way of designing, the computer made designing easier. Lines can be drawn straight and precise with ease, mistakes can be quickly removed, alterations added, and various forms of documentations makes computation greatly superior to drawings. Drawing lacked the flexibility computation offered. However with drawback of computation is being over reliant on it. Due to the ease of computation drawings skills were left undeveloped, designs were made on the computer rather than mentally crafted and some designs lost the appeal of being handmade and human, rather than being artificial. Despite the perks of the computer, people are degrading in various skills in which the computer compensates for.
Computation increases the range of design objectives with ease. Referred as parametric modelling, this tool uses parameters to create the model. With these parameters, they are not permanent, thus their variable can be altered, and this alternation will be reflected in the model. For instance, if one of the parameters for scale was one, I can change it to two, which would make the model overall double in size. Therefore a massive range of models from a singular base can be made with computers. Its as simple as changing one variable, record the alteration, keep/ change the variable, apply a new variable, etc, and through thus process, a final design can be made, based on the various desired alterations made on the base model. Aside from changing the design, computers can be used to test performances as well. The digitalized model can be process through a large range of stimulation such as sun, wind, earthquakes and testing of dead loads. These virtual tests provide results for how the model may perform in such situation, giving designers great insight. Finally computers change architecture in how materials are used. Incorporation with 3d printing systems, complex patterns and details can now be made with ease. In the past, architecture was largely limited to the skill of the labour, and the technology they had to craft. An object too complex, cannot be comprehended by past technology, and cannot be built by hand. Now with 3D printing, despite the complexity, majority of design ideas can be made, and even in a large factory production setting. Thus with this flexibility of 3D printing, design limitations have been greatly reduced.

COMPUTATION DESIGN TECHNIQUES GEA GONZALEZ HOSPITAL FACADE
Fig 18: Gea Hospital Facade
The façade of this hospital was created through the use of both Autocad and rhino. Inspired from sea sponges and corals1 , the forms and patterns were first laid out in a 2d manner on Autocad. Once the pattern was at the configuration the architects desired, they then transposed the 2d drawings into Rhino to generate its 3d form. In addition, each of the cells in the façade had its own different and unique configuration,
22
thus with each unique cell design, Rhino was chosen as it could the complexity and demands of the task. What makes this façade so interesting, is that it neutralizes emissions, retains air toxins and has anti-microbial properties. Thus when air passes through the façade, the façade cleans it before entering the hospital. The façade is made of a lightweight plastic material called Prosolve
370e, which is coated in titanium dioxide. When the sun light hits the façade, the light excites the electrons in the titanium dioxide, which breaks down the nitrogen oxides and other compounds in the air into water and calcium nitrate (an element found in fertilizers). The buy product is then washed off by the rain or wiped off with a damp cloth. The coat is expected to work for 5-10 years, and then requires a respray.
Fig 19: Pattern close up
Aside from cleaning air, the façade also directs light into the building, and slow wind flow to generate turbulence which distributes pollutants better across the facades surfacev . From looking at the design, despite being first made in Autocad, it looks feasible to do in rhino. This project may prove inspiring to my work due to its use in captur-
ing wind. The patterns are not just randomly generated. The shape, sizing and form all were carefully considered to created a surface that captured the wind, and generate turbulence within it so that more air passes through its surfaces to be filter. This idea of smart design can be played onto my assignment by designing patterns that serve as both aesthetically pleasing and serves a definite functional purpose.
In addition, the design was extremely logical in terms of considering the weight, making it a light weight structure for ease of construction, and ease of maintenance .

COMPUTATION DESIGN TECHNIQUES THE PEOPLEâ&#x20AC;&#x2122;S MEETING DOME: KRISTOFFER TEJLGAARD & BENNY JESPEN Built to house debates regarding the future of housing, architects Kristoffer Tejlgaard and Benny Jepsen not only designed a building to a serve as a space, but also designed the building to be involved with the debate. The building is of a de-constructed dome. The geodesic dome was chosen as the primary design as it has all the advantage of being rationally and mathematically generated, but it lacked the qualities of good architecture1. Therefore to change it into good architecture, niches, crevices, corners, opening and hiding were added, but done in a way that respected the properties of the dome2. To find these architectural features, the dome was de constructed, and could be split up, scaled or cut among its surfaces to generate these characteristics.
This lattice served as the skeleton of the building, will gave a great range of flexibility towards the design of the structure. The lack of columns meant larger space, there was no need for load bearing walls as everything was supported by the lattice, thus windows and openings could be placed anywhere. The triangular beams members are clearly the result of using computation design technique. Manually calculating each member by hand is far too time consuming, and has high risk of errors as opposed to using the computer. In addition, the architectures were able to alter their model with ease, being capable of editing various points in their design to generate a desire outcome. Thus from this building shows how useful computation is to design.
The building relied on a system of nodes in steel, which connected to wood to form a complex lattice structure.

A.3 COMPOSITION/ GENERATION Composition refers to the organization of building elements; the placement of rooms, function, space and materials. It was the layout that created the design. In this architectural sense, design through composition is the reuse of pre-existing materials and resources. Computerization broke the bonds of the architectures mind. It drove to infinite possibilities unimaginable to the human mind. With computation, humans can design both means of composition and generation. Generation refers to the actual creation of a design. It is the creation of brand new forms and exploration of already conceived geometry1 , all through the various techniques of computing. Rather than draw straight on, the completed outcome in traditional sense, different input and variations2 are applied to a computerized formula to produce the form. As stated previously, what computation bought were designs too complex for our mind to comprehend without aid, and details take would take years to sketch by hand. The bringing of the digital age transcribes the skills bounded by pen and paper. With this architecture went beyond designing through composition, and looked into design via generation. It is the creation of design unshackled by limitations held by the world before digitalization. Computation bought a new way of ‘architectural thinking, that ignore conventions of style or aesthetics altogether in favour of continuous experimentation based on digital generation and transformed of forms that respond to complex context or functional influences, both static and dynamic’.
Algorithmic thinking
‘A finite procedure, written in a fixed vocabulary, governed by precise instructions, moving in discrete steps and that sooner or later comes to an end’ -David Berlinski Algorithmic thinking refers to the mathematical thought process used to produce and comprehend designs through computational aid. It allows ‘designers to work in intuitive and non-deterministic ways’3 . Algorithm itself is a set of instruction written in code to be understood by a computer4 , in which both architects and engineers use ‘for conceptual design and generation of buildings’5 . Algorithm is the mathematical or logical exchange between the computer and designer, and by understanding the maths process, can we understand what is being built in the software, how it is being built, various input we can apply to customise that item, know how to modify the code and to speculate on future design potentials’6 .
Parametric modelling
“Parametric modelling introduces fundamental change: ‘marks’, that is,parts of the design, relate and change together in a coordinated way”7 -Robert Woodbury Parametric modelling is 3d computer modelling where mathematical principles (parameters) are used to define

a 3d object. There parameters are generally dimensions which can affect any of the models characteristics such as features, materials, surface and textures. This plays great flexibility as the change in parameters is reflection upon the change in the model. For instance, parametric modelling can be used to subject ‘in certain situations to the rigors of a pre-defined and proven mathematical model’8. Therefore models can be stimulated to various desired testing, making the testing of design easier. Parametric modelling is best seen in the work of Micheal Hansmeyer. Micheal Hansmeyer is a digital architecture who creates impossibly complex but buildable objects through the means of parametric modelling. In his work, mesh grammars, he demonstrates the complexity and power of parametric modelling. Using a simple and primitive dome as the supporting base, Hansmeyer continuously folds the domes, altering the parameters and conditions to create a large array of unique geometric shapes. Each shape is unique as it has it own parameters adjusted to it. Through the alteration of folds, and repeating such process over and over again, the result is remarkably unique due to the repeated pattern of personalized alterations. Hence this project shows the power of parametric modelling. Despite making a model fold over itself, which is generally a simple step, by doing this a thousand and more times, crafts a incredibly complex object. And complexity isn’t a issue towards it construction, due to the 3D printing, Hansmeyer was able to produce some of his work such as his columns.
Fig 22: Samples of Hansmeyer’s domes Its incredible to think that these beautiful, and highly complex objects were made from the same simple action repeated a thousand and more times. If such beauty can arise from a rather insignificant action, perhaps we also process the capability to doing such as well in Grasshopper.

SCRIPTING CULTURE HERZOG & DE MEURON
Scripting culture Scripting is essentially writing an advance computer language to create a certain program, or a mod to preexisting soft wares to generated desirable customizable outcomes. The customizing effect is greatly desired for designers but it requires learning a programming language, and these languages play part in algorithmic thinking. With scripting, it allows designers to generate programs or extensions, that either didn’t previously exist, strings together multiple actions to make the process faster, or handle task outside the main programs protocol. Hence scripting is useful to a designer, as the designer essentially creates a personalized tool to help with his production. Scripting is best described by Oxman as:
‘The growing capability for scripting the algorithms of a mediated variability that can be selectively studied for performative behaviors such as energy and structural performance provided a new creative professional profile’1 .
Herzog & de Meuron Herog & de Meuron is an architectural firm that embraces the scripting culture, using it side by side with their work. Scripting is a significant part to the firm as it allows them to ‘find the right tool, and develop the tool to make the concept work’2. As scripting and other program is a highly
skilled computer task, the firm has it’s own digital team, called The Digital Technology Group, which specializes in computer-aided design (CAD) management, building information modelling (BIM), parametric design and scripting,visualization and video, and digital fabrication3. By having it’s own computer specialized team, the architects can use them to help create custom tools and scripts for particular jobs. The Digital Technology Group consults with the designing team, to ‘grasp the idea the office’s designers are trying to develop and then write a specific tool for it’4. Doing do ensures that the tools are right for the job, and is made so that the designers themselves can easily understand and use5. Another perk of the Digital Technology Group is the various stimulations they can create to test the designs. ‘When considering aspects of performance in the architectural design process, feedback from engineering consultants is sometimes slow, and there is a need for feedback that is quicker and simpler’6. Thus the group creates tools for the architects to stimulate the results themselves, thus allowing the architects to react much faster to design iterations7. From this it shows the perks of understanding scripting and employing its uses in design. With Herzog & de Meuron, they have their own specialized computer team, which craft custom tools and scripts for the designers to use in response to various design requirements. In addition these tools are crafted for that particular need, and to the user, making it easier for the architect to understand and use.

GENERATIVE APPROACHES
THE NATIONAL BANK OF KUWAIT HEADQUARTERS: FOSTER + PARTNERS
Designed by Foster + Partners, the National Bank of Kuwait Headquarters, Kuwait City, is a prime example of a building designed through parametric modelling. With Foster + Partners specialist modelling group (SMG) being involved in the early designs, they were assigned to develop a parametric model that ‘would integrate different performance parameters and would be able to explore complex geometrical solutions for the building’1. The team used Bentely Systems’ Generative Components as the primary parametric modelling tool2 . The design was driven by the response to the local climate3 . The tower had shading fins on the eastern and western façade, while the north was opened up to bring in natural light and views4 . This showed that parametric modelling is not only used to form a complex design, but also used to generate a response to the nature. The primary elements of the geometric shape of the design are the fins, profile of the edge, the cladding between the edge, and the arches that formed the north façade5 . These primary elements formed the overall basic shape of the parametric modelling. Then through extensive testing and modification, the final design was drawn through the initial basic shape. Parametric modelling offered great flexibility to the design team as it allowed various parameters to greatly adjust the overall design. With this, the team generated a great range of building shapes. These shapes were then stimulated against environmental factors such as solar, wind and acoustic, rendered and made into physical prototypes. Hence through this continuous testing, simulating and building, the perfect model was built that adhere to the desired design ideas, whilst performing both structurally and sustainable.
Parametric modelling also offered flexibility to the engineers as well. The model contained full geometric description of the construction build-up of the builds, and also embeds engineering input through linking to data spread sheet6 . In addition, in the model, the section profiles for the fins were fully adjustable to allow design investigations7 . This building shows the great importance of parametric modelling. Without parametric modelling, the perfection of the design might not have been conceived. With parametric modelling and its ability to adjust majority of its parameters, the designers were able to test a vast range of ideas with ease, and furthermore stimulate these designs environmentally and structurally. With each design made, the preferred elements could be recorded and placed in the next design. Thus slowly with idea, and taking in its preferred element and adding it in to the next design, the final design was perfected through this large range of testing. Parametric modelling allowed designers to test and modify their ideas with ease, which is why it is such an important tool for designing today.

GENERATIVE APPROACHES SUDPARK BAUFELD: HERZOG & DE MEURON
Sudpark Baufeld by Herzog & de Meuron is another example of architecture that uses both scripting and parametric modelling. The design intent of this building is ‘to render the historical character of the differently shaped windows in the Gundeldinger Quarter in a contemporary architectural idiom’1. Aside for making in aesthetically pleasing facade, the windows are designed in such a way to ensure openings for natural light, offer views, and giving niches for storage2. As stated on Herzog & de Meuron’s website, ‘the façade consists of 12 freely combined window shapes, which fuse into meandering, right-angled windows designed to match the scale and daily activities of human life. At selected places in the building, the façade is extruded inwards, creating sills that can be used, for instance as seating. Casing runs all around the windows on the outside’3.
sheets as a way of checking the data’6. This shows how useful scripting is to the production of design. With their own personalized script, not only was it something they are familiar with, hence everyone in the team and understand and use, but it was used to double check error and of the various facade design made by the parametric modelling. The scripting basically runs with the database it was given, compare it with that of the facade design by the parametric modelling and enure that all the windows are at the right size and position. This makes data checking much easier for auto- correction. Basically this building demonstrates the ease of scripting and used in conjunction with parametric modelling, can create a building with ease, that fulfils all the requirements. Scripting in this scenario checks if the requirements are fulfilled. Hence with benefactor, scripting seems to be a must for any parametric modelling.
To create the random arrangement of the various sized windows, the architects, in conjunction with the CAAD chair at Federal Institute of Technology, used both parametric modelling4 and scripting. Randomization was first used to generate the initial pattern5, then developing developed, the parameters were altered to created the desired outlook and performance without hindering that randomized look. For this building, a script was used to help check the data. First the database was produced, collecting information such the sizing, the type, and the amount of particular windows. Rhinoscript was used as the spread sheet for the collected information. In addition, Rhinoscript was also used for production drawings. With these collection of information, a script was made to ‘re-generated a complete facade from the production information and spread-

GENERATIVE APPROACHES AL HAMRA FIRDOUS TOWER: SKIDMORE, OWNINGS & MERRILL
This tower was also designed through an algorithmic design process1, but unique in its own sense as the form was developed through a subtractive process, similar to that of ‘chiselling out the parts that are not needed from a block of stone’2. So rather than design the object itself, the architectures worked on what to remove, which creates a ‘phenomenal artefact that has a perpetual dialogue with its missing counterpart’3. In addition,through parametric studying, the geometry is based on a set of criteria based on the environmental factors such as solar exposure and wind loading4. This makes the tower unique as the design follows only the site conditions. As stated by the project development manager Farid Abou Arraj:
‘The tower responds to its context and cannot be repeated elsewhere’. For instance, complex environmental software was used to race the path of the sun, and with the results, adjusted the curvature of the wall to match the trajectory5. As a result, the most efficient sunshade through out the day, and through the years.

The rain screen walls and stone panelling followed a reference geometry which was rationalized through a computational process of point clouds and scripting6. The algorithmic approach created a’ rule based framework for a series of interconnected and interdependent processes to occur’7.

CONCLUSION From looking at the past portfolios of the land art generator initiative, I gained a slight understanding on how to design a structure that could generate various forms of energy. The Art Wind Energy Unit showed me how its shape can be used to its advantage to funnel in wind and concentrate it through turbines to produce power. In addition, they showed good justification in the use of materials, and detailed diagrams showing how it works. They presented a realistic argument with evidence to prove their claims, and in conjunction with their diagrams, was a very persuading piece. Hence from this, I want to somewhat mimic what they do. I want to have diagrams as detailed as theirsâ&#x20AC;&#x2122; to show the functionality of the design. I want to show a list of materials, with reasoning to why they are used, to show the audience that research has been made, thus there is credibility in the work. And finally I want to show the maths, present how much energy the design can make, again for the justification and because maths is fun. The other precedent, Bio Reactions, was not as persuading as the first. I choose to study this as I was interested in using algae as bio fuel. The information was great, but the design looked poor and confusing. It seemed to be a maze without correct logic to why each element is placed there. Many of the designs did seem impractical and were designed solely based on looks rather than the production of energy. To me, production of energy is the most important. Designing a space that looks good, but has low gains goes against the idea of sustainability. It essentially is wasting space which could have housed a more productive unit. For computation designed buildings I looked at Gea Gonzalez Hospital and the peoplesâ&#x20AC;&#x2122; meeting dome. From looking at these two buildings taught me the realism of
36
3d modelling to product an actual product. That despite its complex look, it can be both be easily formed on the computer, and installed by hand. The energy I studied is algae, magnetic flux and solar heat. In its simplicity, it was the growth of algae to create biofuel, using kinetic, gravitational or mechanical energy to cause a magnetic flux to make power, and using the heat of the sun to boil water thus making power. I want to create something that works day and night, and uses multiple energy sources. By having multiple energy sources, production of energy can be continuous. For instance, have solar panels for the day, and wind turbines for the night. Also the output of some energy sources can be used as resources for other energy source. For example, the waste water from collecting algae cause is used to extract hydrogen, to produce hydrogen fuel cells. Thus I want to create multiple energy sources that work with each other, overcome each of its weakness, and can continuously produce energy. So the current Idea Iâ&#x20AC;&#x2122;m thinking of is a solar heat and algae configuration. Solar heat evaporates the water from the nearby river; the evaporation is captured and used to farm algae. The left over salt from the river is collected, concentrated and also exposed to sun. This molten salt then serves as a battery for night-time use.
LEARNING OUTCOMES The past few weeks were extremely fruitful for me. I learnt so much in particular to the usage of grasshopper, which has greatly altered how I would generate and produce designs. In the past I was greatly restricted to what I could do on rhino. My skills in Rhino determined what I could design. In order to be realistic and practical, I developed ideas that I could easily create. Ideas that were too complex required too much manual work or too time consuming were simply abandoned. Now with my basic understanding of grasshopper, my boundaries were lifted. For instance, in the past I created simple surface patterns, and some instances, even manually inputted patterns of these surfaces. Now with grasshopper, I can create complex patterns with ease, and have them altered with various input, which cannot be done in Rhino alone. In addition my design mind set has changed as well. Now I can think more mathematically and applies these formulates to a design. In the past I simply crafted the model on Rhino. Now I can input formulas that create those models for me. With this new knowledge, I could improve the model I made in Virtual Environments. For my model, I used simple rectangular patterns for form and openings. I simply trimmed a rectangular hole, and applied that to the entire surface of the model. Now with this understanding, I could have made a different pattern, perhaps a more complex opening, or even a 3d mesh. My imagination bounded by my experience with Grasshopper.
37
ALOGRITHMIC EXPLORATION For this piece, I wanted to create a interesting surface that had a 3d pattern. So i first made three boxes stacked on top of each other on grasshopper. With the box created, I then made a large curved surface, subdivided the points, and applied the box on top those points. The height of the boxes is dependent on its location along the y axis, and I multiplied these variables to gain a more exaggerated effect. Making the boxes was the most interesting aspect. I had fun developing these 3 boxes from using only one curved crafted on rhino. The rest were made entirely on grasshopper. From making the boxes, I learnt about the proprieties of duplication. Initially I used duplication in grasshopper to get two points to loft. What I didnâ&#x20AC;&#x2122;t know is that duplication holds two same points which cannot be lofted. From this I found out that you can use the past input (before it got changed) and the changed input to loft together, rather than make a copy of the past input that wasnâ&#x20AC;&#x2122;t used.
38
39
ALOGRITHMIC EXPLORATION This piece was purely a mistake, but the resultant was great. From doing what I assumed a simple task on grasshopper, I had a general idea of what the end result would look like, but I had a miscalculation and accidently created a beautiful mess. My initial plan was to create a simple surface, make contours on it ,project a copy of those contours in the x/y plane and have those two contours loft together. Instead, the contours lofted with itself, and lofted with each other, which made this surprising result.
40
41
42
ALOGRITHMIC EXPLORATION For this experiment I decided to combined the things I learnt from the videos transform menu and creating a grid shell. I ideally I wanted to create a grid shell that had long skinny column protrusion of various heights. So using what I learnt, I made the dome, divide the surface into various surface boxes and used a skinny column as the geometry of the box morph. The pattern wasnâ&#x20AC;&#x2122;t what I desired it to be. The columns were short and fat, opposite to what I wanted. So I made the surface be divided into much smaller points, which somewhat fixed the issue to a small extent. This is where I meet the limitation of my desktop computer. When I tried to divide the surface even more, and increase the change in height in the columns, my computer lagged greatly. Thus I reached the limitation of what my computer can do. It wasnâ&#x20AC;&#x2122;t want I imagined it to be, but my goal was far too complex to create.

DESIGN INTENTION ALGAE BIOMASS
Algae biofuel is the selected renewable energy source. As quoted by astrophysics Neil Degrass Tyson, photosynthesis is absolute best means of converting light to energy, thus algae is the perfect for tapping into this resource. As mentioned before (in part A), the advantages of algae are: - it is carbon neutral - It is quick and easy to grow - Its grow rate exceeds that of other biofuel plants - The fuel is stored energy, providing flexibility as opposed to pure energy (electricity) - Algae in its entirety can be completely harvested for various means Resources generated through algae1: - Lipid oil. Through extraction it becomes biodiesel - Carbohydrates. Through fermentation becomes bioethanol - Protein: Cattle feed or plant fertilizer Therefore with algae as our energy source, considerations for our choice on precedents and parametric techniques need to be based on: 1) Ability to house the algae and water 2) Provide maximum surface area for full sun exposure 3) Provide addition spacing for utilities such as pipe works and structural support systems 4) Generate some aesthesis influenced by algae eg: let light penetrate through the algae for visitors to experience the green light hue.

B.1 RESEARCH FIELD
ARAVENSBOURNE COLLEGE: FOREIGN OFFICE ARCHITECTS
The following precedents will be examined to understand the variation in tessellation patterns, how the patterns are generated, and the functionality of the pattern. This research analysis will exposed the adaptation and limitation of such pattern arrangement. The Ravensbourne College has a tessellation pattern façade surround the entire building. The pattern shapes are inspired from ‘gothic rose windows and follower patterns’1, but is an abstract form of the source rather than an imitation. From analyzing the pattern, there seems to be four various shapes; triangles, rhombus, and two different five sided polygons. With these four different shapes, not only goes the pattern conform to the rule of tessellations, which are no overlays and no gays, but also bring great flexibility of generating window openings. The size, amount and position of window openings are based on the interior room function and its orientation2. For instance, the north façade has more window openings to allow greater amount of light penetration as opposed to the south façade3. Due to the five shapes and non-periodic tiling nature of the pattern, seven different size windows can be built. In addition, different amounts of windows can be placed without interrupting the pattern. This tessellation shows the strength and flexibility this pattern configuration can bring based on the choice of the geometric shapes chosen for the pattern. As shown in the Ravensbourne College, the choice in the five shapes allow the architects to design seven different sized windows, and allows them to have various amounts of window penetration without breaking the rules of the pattern itself.

B.1 RESEARCH FIELD VOLTADOM: SKYLAR TIBBITS
VoltaDom is an art insulation that populates the corridors of two corresponding buildings on the MIT campus. It consists of â&#x20AC;&#x2DC;connecting vaults of various sizes, paying homage to the vaults we see in great cathedralsâ&#x20AC;&#x2122;1. The vault is made from a white translucent plastic, and in conjunction with the holes in the center of each vault, brings in a beautiful white glow from the interior. On the exterior reflects the shiny surface of the plastic. The VoltaDom explores the notion of surface paneling in Architecture whilst maintaining the ease of construction. It devises a complex look, due to the numerous amounts of vaults and all in its own unique form, however in actuality is very simple to make. Each vault is essentially a deformed cone with an opening where it apex would be. Therefore its unrolled version would be a simple strip2. This makes mass production of different cones quick and easy to install. The vaulting pattern of the piece is that of tessellation. Again there are no overlays and gaps between each element. However what makes it different to tradition tessellation is that it does not use shapes that fit perfectly with one another, instead the cones are forced together in a tight space to ensure that there are no gaps, and then the overlaps are trimmed off. The materials used for this project are plastic and metal bolts. From the metal bolts, it can be assumed that the plastics are highly elastics (wanting to go back to its original form) when folded to a cone shape, thus require these bots to hold this shape as other substances such as glue and tape are too weak. Therefore consideration must be made in regards to the pattern form itself, and the bonding substance, to be able to withstand forces imposed towards deforming plastic.

B.2 CASE STUDY 1.0 Through creating sequences of geometric variation,we were trying to create a pattern that was highly complex, interesting and extremely different from the original. As encouraged from the tutors, we wanted to make something that pushed the bounds of the algorithm. Thus the major changes we applied was changing the original shape, increasing the population and density, and changing the point population from 2D to 3D. The patterns created, generally were porus in nature and tightly bounded. Therefore, in terms of architectural features, they can serve as roofs and shades. The holes allow light penetration, and the patterns would serve as the main surface. These four iterations have been chosen as they satisfy the following five criteria: 1: Conforms to the rules of tesselations 2: Can be further developed in grasshopper 3: Can be unrolled/ physically produced 4: Is different from the original algorithm 5: The surface can be used for algae growth These four iterations are considered to be more successful than the orders as they are quite different to the original mesh produced by the VoltDom grasshopper definition, and have gone through significant changes in their algorithmic sequences. They also followed the generative computive process, where the designs were not pre conceived. Thus production of the iterations were generated through random testing and alterations with no though on the end products. In terms of using it for the chosen renewable energy source, the surfaces for each the iteration can be used to house the algae. The holes on top, in particular to the conical shaped patterns allows light to penetrate through, which shines underneath the algae, thus increasing growth rate. In addition, the holes allow services to go through such as pipe works or structural support.

ATMOSPHERIC TESSELATION: CHRIS KNAPP, MICHAEL PARSON
Figure 8: Atmospheric Tessellation by Chris Knapp, Brendon Doran, 2013
Atmospheric tesselation is a temporary light installation exhibited in the streets of Wellington. Built to enhance the urban experience of the pedestrians, the installation has both spatial and aesthetic features1. It can be configured to serve as a space architecturally as well as be conceived visually with the usage of motion detecting lights. Inspired by naturally occurring tesselation such as turtle shells and giraffe skin, the designers wanted to apply a biometric surfaces on a curved geometry2. Thus they used voronoi tesselation to generate a complex surface with an organic array of shapes, similar to plant cells and cellular bone structure3. This is developed with the plug in ‘Grasshopper’, in which the designers created a parametric script that generate the pattern and allows alterations be made towards the geometry4. Another perk to the usage of grasshopper is that the final files used to laser cutting is updated in conjunction to the changes made to the parametric script. Regarded as ‘file to factory’ project,
62
this live update feed greatly decreased production time of unrolling, and alters when geometries are too complex for it to resolve5. The skin of the installation is made from high density polyethylene (plastic found in milk jugs) and the frame made from lightweight plywood. These are materials are used in digital fabrication, where the plastic is laser cut, and the wood CNC cut. Afterwards the materials are assembled by hand. With our group’s interest in algae biofuel, we chose this precedent as our case study of reverse engineering as it presented opportunities appropriate for our energy source. As mentioned before the usage of tessellation grants maximum surface area exposure towards the sun. The 3D projections also increases the potential surface area and can also serve as both pods for algae growth and storage. The spacing between the pods, can serve
Figure 9: Geometry, Nicole, 2013
as the service area for input and output pipes, and also be where the structural framing are located. In addition, the ease and type of assembly is something we may apply as well. Unrolling the pods and surfaces, and building these separately seems to be the most efficiently and logical way to build these 3D tessellations. 1: N/A (2013) Atmospheric Tessellation, Available at: http://lux. org.nz/atmospheric-tessellation/ (Accessed: 10th April 2014). 2: N/A (2013) WGTN LUX 2013: ATMOSPHERIC TESSELLATION BY CHRIS KNAPP & MICHAEL PARSON, Available at: http:// www.illumni.co/wgtn-lux-2013-atmospheric-tessellation-by-chrisknapp-michael-parson/ (Accessed: 9th April 2014). 3: N/A (2013) Atmospheric Tessellation, Available at: http://lux. org.nz/atmospheric-tessellation/ (Accessed: 10th April 2014). 4: N/A (2013) WGTN LUX 2013: ATMOSPHERIC TESSELLATION BY CHRIS KNAPP & MICHAEL PARSON, Available at: http:// www.illumni.co/wgtn-lux-2013-atmospheric-tessellation-by-chrisknapp-michael-parson/ (Accessed: 9th April 2014). 5: Ibid

B.3 CASE STUDY 2.0 REVERSE ENGINEERING
STEP 1 A triangle was first created on rhino to serve as the base. Then with the usage of voronoi, move, scale and loft, the general protrusion was made
STEP 2 The pattern was applied to a surface using boundary box. However the pattern surface generated was found to be largely deformed and have spacing in between, thus not following the tesselation principles.
STEP 3 Triangular was used to generate a grid to tessellating triangles. The issue with using this was that it couldnâ&#x20AC;&#x2122;t be applied on a 3D surface. In addition the triangles were too perfect, they couldnâ&#x20AC;&#x2122;t be stretched and compressed as found in the Atmospheric Tesselation
64
STEP 4 The surface was divided into point lists. These point lists were essentially moved connect and make the triangles. Whilst the definition looked similar to the precedent, and followed the principles of tesselation, it was very complex, thus was very slow when altering the parameters.
STEP 5 The lunchbox plugin was discovered and its paneling tool was using to make quick and easy triangle patterns. The definition computed faster than the previous and offered a wider range of flexibility in terms of alterations.

B.3 CASE STUDY 2.0 REVERSE ENGINEERING OUTCOME
The final outcome of the reverse engineering project was quite successful. After several attempts of finding the right way to properly divide a surface into triangles to host the 3D protrusions, the solution was within the plug-in Lunchbox. The 3D protrusions themselves were made with voronoi to create the central division, and through a series of scaling, moving and lofting. The reason the reverse engineering outcome was successful as it; conformed to the rules of tesselation, could be applied to a range of surfaces, and it looked quite similar to the precedent as shown on the images to the left. However the main difference is was that the triangles used for the surface division are right handed triangles as opposed to the equilateral triangles used in the precedent. By using different triangle types the protrusions looked different as well. In the precedent, since the base triangles are equilateral, all three protrusions within those triangles were divided evenly, thus had the same appearance and size. As opposed to the reversed engineered outcome, with the triangles being right angled triangles, the protrusion within it were not divided evenly, thus causing different sizes and shapes. In addition to led to a more stretched hexagon pattern of the voronoi spacing, in which was a equal triangle in the original precedent. Now with a satisfied outcome, the next step will generating a outcome that responded to the sun. Having the protrusions face the sun path, and perhaps based on its location will determine its sizing. Hence the protrusions will be optimized to accelerate algae growth. Also the form need to be worked out to host these patterns.

B.4 TECHNIQUE: DEVELOPMENT Three definitions were created to generate a large variation in pattern generation. The original definition from reverse engineering posed no flexibility in producing large range of patterns. The other two definition stemmed from the original, the only difference is that they both have difference forms of surface divisions, one being hexagon cells, the other triangular panels. Referring to Kalay’s two search techniques1: (1) producing candidate solutions or consideration (2) choosing the “right” solution for further consideration and development. These two points were applied in the evolution of the iterations. For instance, in the initial iteration responses, it was found favorable to have large pods, thus adjustments were made in later iterations that had larger extruding pods. In addition, logically more surface area was exposed when the head of the protrusion was smaller that the base, thus more experiments were made developing more pyramid shaped protrusions. Adjusted selection criteria for the betterment of algae production: 1: Conforms to the rules of tesselations 2: Can be unrolled/ physically produced 3: Is different from the original algorithm 4: The 3D protrusion are exposed in a sense that further maximizes surface area 5: The 3D protrusions can be used as pods to house and grow algae 6: Spacing between protrusion is large enough to have pipes or structural support in between 7: Is aesthetically pleasing/ interesting

B.4 TECHNIQUE: DEVELOPMENT Form Initially the primary criteria for the form was: 1) To be longitudinal from east to west for maximum solar gain 2) To be a cave like structure so people can go inside experience the algae light radiance 3) Consist of various curves for a more interesting surface Initial form modelling was made with small pieces of paper. The paper were twisted, curved and bent which then was translated into rhino. With these paper influenced models, the virtual model was further experimentation on, adjusting various control points to generate different surfaces. As shown to the left, the small surfaces evolved towards a cave light structure. The idea of developing a separate branching grew. However it was decided to abandon the cave structure criteria, and instead a less enclosed surface was found to be more favorable. This was so that the design was more spacious, and the green hue light wasnâ&#x20AC;&#x2122;t too concentrated. With the cave like structure, it was believed that the visitors may experience too much green, as the only light source was those that went through the algae pod. By having a more opened space, outside light can mix in with the interior, thus creating a more balanced appeal.
Final Form In the end, this simple twisted surface below was chosen. The simplicity of the form meant that it ease of assembly. The curves served as the interesting feature. Itâ&#x20AC;&#x2122;s extremely open, which was a desired feature found later on in form experimentation, and its rectangular in size. Being rectangle meant the maximum sun exposure to what the site offers, as the site shape itself is rectangular.

B.5 TECHNIQUE PROTOTYPE PAPER MODEL
Figure 12: Printing layout, Henry Chhen, 2014
The building technique for the precedent Atmospheric Tessellation, where the 3D patterns and structure were made separately, was tested on these two simple hexagon patterns. Each of the protrusions of these patterns were separately unrolled on rhino and printed on paper. Then they were all manually cut out and stuck on paper. The simple models were made with ease, and faced no complications, thus this method was applied to the larger scaled models that will be printed off through the laser cutter.

Figure 15 -17: Prototype 3
Prototype 3: Quad subdivide
The quad subdivide turned out to look really cool. Its Z structure and black color gives it that engaging appeal. The model it self was extremely flexible yet rigid at the some time, and could be compressed or stretched out. However the only issue would be the difficulty of producing this in a large scale model. With the aim of fabrication to be quick and smooth, this on the other hand was difficult and took a long time to do.
81
82
Figure 18 -20: Prototype 4
Prototype 4: Constant quad subdivide
This is a series of inverted pods on a quad divided surface. WIth its largest face facing upwards, it has maximum exposure to the sun, however with the loss of the sides being blocked by it. The model itself was very weak as it relied purely on the paper underneath to hold it, as opposed to the others, where the pods are held together (in this one the pods are isolated). However, the large spacing in between each pod allows pipes, services or each structures to go through, whilst being hiding it at the same time. This may be a desirable feature later on the development of the design.
83
84
Figure 21 -23: Prototype 5
Prototype 5: Hexagon cells
Despite being simple in design, this model was very pleasing to look at. The one feature that it has, in which the other models lack is that it had a interesting bottom side as well. So people from below can look up to these marvelous coffers high above them, in which will also be filled with algae. The hexagons themselves can house the algae quite well, and they donâ&#x20AC;&#x2122;t seem to overshadow each of its neighbor. Furthermore, the structure is surprisingly rigid and flexible. It can hold quite a load whist still retaining its shape. From producing this, all this beneficial aspects it contains (especially with the amazing underneath coffees) is playing quite advantageous for this to be our choice in patterning.
85
B.5 TECHNIQUE PROTOTYPE LIGHT EXPERIMENT
Figure 24: Prototype 4, Constant quad subdivide Using green cellophane and shining light through enabled us to visualize what our design may look life if it were to shine through the pods. Obviously the light produced here is too artificial, consist ant and green to what the real one would look. The real ones will have a greater variance in green hue and would most lightly be light in
86
colour. However, the light does convey through the patterns nicely, giving these rather cool futuristic appeal. For the real study however, we want to grow enough algae and place that in actual water tight prototype pods. This will give us a more realistic study, and provide

No complications were met during the making of these models, thus the building method will be kept and used for latter models. In addition due to the ease of construction, no alterations are made towards the definitions. Each model was quite rigid and strong, however when experiencing downwards force from the top, it will start to sag. Hence considerations need to be made in figuring out how to increase its strength. Once solution is making the base surface thicker, and supporting that with structural members such as wires, mincing real time support beams and columns. Aesthetically, these patterns were quite pleasing, in particular to the light experiment. Seeing the green light effect against the shadow was beautiful and is a effect we want to employ. The model themselves were nice, clean and interesting to look at. The one that stood out most was the hexagon pattern. Not only did it look good externally, but it had a extremely interesting layout underneath it, similar to coffers found in buildings. From this, it was decided that the tessellation hexagon will serve as the primary pattern for the final model.
89
B.6 TECHNIQUE: PROPOSAL ALGAE PROCESS DIAGRAM
The site provides great advantages to the growing of algae due to the availability of local resources. As shown in the diagram above, both seawater and sewage water from the local waste water plant can be used to grow the algae. The waste water contains nitrate, phosphate and various material compositions necessary for algae growth1, therefore external fertilizer is not needed. In addition CO2 can be tapped from local workshops and from the waste water plant.

90
The climate is also suitable for algae growth as well. The site can receive up to 17 hours of sunlight, with the light reaching up to 25 degrees, all appropriate settings for algae. However Copenhagen is quite cool, and whilst algae can survive in 5 degrees, some form of insulation or barrier must be considered to keep the water in optimal temperature (22-28 degrees).

EXTRACTION PROCESS
27: OriginOilâ&#x20AC;&#x2122;s Single-Step Algal Oil Extraction
The chosen extraction system is the single step oil extraction by Origin Oil. Current algae processors such as solvent extraction are either energy intensive, uses hazardous chemicals or is costly to run, thus defeating the purpose of using algae as a green fuel alternative1. The main reason we chose this system is that it has no of these drawbacks, but is still equally or more efficient than the current processes. This extraction process only requires low voltage, which can be generated through solar panels, and CO2, which can be harvested from local workshops. This makes this process entirely carbon neutral. As shown in the diagram, this system works by breaking down the algae with electromagnetic pulse and increasing the acidity of the water with CO2. This is then collected in the gravity clarifier. In this chamber, the oil released from the broken cells float on top of the water, and the biomass sinks to the bottom.

93
B.6 TECHNIQUE: PROPOSAL ALGAE COLOUR TEST
We wanted to gather algae samples in order to understand the colour variation of various species, the colour in different growth stages, and the hue produces when the light goes through it and the its rate of growth. Thus we collected algae samples from ponds, lakes and labs and attempted to grow some in our own backyard. The first image to the left is samples we either grew in our backyard and gathered from local lakes and ponds. The samples we collected did have algae in it, but it cannot be seen in this photo. Due to the lack in algae mass, we couldnâ&#x20AC;&#x2122;t really study the light and colour. Figure 28: Home grown and pond/ lake gathered samples
The second image is the algae species chlorella vulgaris that we received from The University of Melbourne lab. With this we altered the intensity of the algae concentrate to mimic that of its growth stage. The various green hues can be seen behind each sachet. From this we can see that each stage produces a rather soft translucent green glow that can be used to light up the internal space of our design. However the more mature algae stage produced rather dark green, thus consideration must be made on the placement of mature algae stages within the pavilion in order to not create dark/ dead space. Figure 29: Chlorella vulgaris at different intensities
The last image uses food dye. We werenâ&#x20AC;&#x2122;t satisfied with the range of green we gather, thus decided to artificially produce our own. Each sachet is unique in terms of having different amount of green dye added, and having other colours added to it as well such as blue and yellow.
Figure 30: Food dye
94
MATERIAL SELECTION Algae The main species of algae grown in the site will be the chlorella sp as it is the one of the most popular choice for algae biofuel1. However other algae species will be used for a wider variety of colour. In particular to breeding bioluminescent algae for the pavilion’s night time use.
Pods Acrylic Plexiglas shall be used to create the pods. It is essentially thick clear plastic. The reaons this was chosen over glass are2. 1) Light weight 2) Used for large scale aquarium tanks 2) Flexibility in producing various shapes and forms 3) Extremely strong and nearly shatter proof. Therefore is perfect for public spaces 4) Extremely durable overtime. Glass requires silicon sealing which has a life span of 10-15 years. Acrylic Plexiglas can last a life time 5) Easy to adapt. Holes and other modifications can be added to it. This material is extremely appropriate for this design. The benefits it beings are advantageous towards the pods construction, as opposed to using glass. It poses such flexibility, that the designs of the pods are not limited by the material.
Structural support The structural support for this designs needs to be light, strong, water proof and be able to withstand both compressive and tensile forces, thus stainless steel is chosen. Despite being expensive, it’s benefits outweighs the cost. Stainless steel doesn’t corrode, which is very important due to large exposure to water.

B.6 TECHNIQUEv: PROPOSAL FINAL PROPOSAL
Figure 31: model perspective
‘To create a pavilion that incorporates algae biofuel energy in an integrated and localized manner with the site. It will provide both an experiential atmosphere for the users of the site as well as an informative one, through a process of enquiry by design.’ This design is innovative as uses Grasshopper to generate both the form and tessellating pattern embodies architectural qualities whilst adhering to the LAGI brief. In addition, the idea of pods structures is quite unique as other algae generating ideas and buildings studied have all used panels, pipes or open ponds. With the pods each hosting various stages of algae ety of green hues within the building when light shines in these array of green light, but they can interactive chairs, tables, and even as a climbable playground for
growth, ideally it’ll create a wide varithrough it. Not only do the visitors bask with the pods. The pods can serve as children - all serving as public furniture.
Aside for designing aesthetically, focus on the functional response have been one of the primary focus. The pods and its tessellating arrangement have been chosen due to its potential for maximum surface to sun exposure, allowing greater and faster algae growth rate. The form as well was generated to exposure the pods to the sun path direction.

B.7 LEARNING OBJECTIVES AND OUTCOMES Our presentation went surprisingly well. As remarked by the tutors, we were convincing in our design intentions as we were able to properly justify our energy source and showed how it relates to our design. We received a lot of constructive feedback from them which helped us greatly and sparked our creative drive. Here are the few main points we were told to work on: 1) Use the sun path definition on grasshopper to figure out the height, sizing, angle and arrangements of the pods for maximum algae growth 2) Have the patterns at various heights, but the heights must be optimized in a way where it doesnâ&#x20AC;&#x2122;t overshadow neighboring pods 3) Use the various stages of algae growth to create bands of random colours. We need to study the stages of algae, the time it takes to get to each stage and what it looks like. In addition we need to figure out how to transport these stages into different pods. 4) Taken into consideration the approx. volume on the total pods. This will help determine the processing plant size. 5) The entire does not need to entirely covered in the chosen pattern
plied with each algae growth stage. For instance, have the young pods appear at every fourth pod etc. Thus we need to figure out which area we can have this sort of patterning that isnâ&#x20AC;&#x2122;t detrimental to the algae growth potential.
Objectives: 2) As shown in B.2 and B.4, parameters of the definitions were greatly altered to generate various forms of design. This involved changing numerous numerical factors such as scaling and the height/ movement of points, and also changing the definition itself by adding and replacing various parameters. Changing the definition achieved more unique responses, for instance in B.2 using the VoltraDom definition, we change the shapes from cone, to cylinders, spheres and a mixture of the three. We even changed the 2D populate to 3D, generating a pattern of various heights with significant overlaps and gaps. For B.4 in our own reversed engineered definitions, we altered the surface division to generate more varied responses. Thus we used constant subdivide, hexagon cells and triangular panels.
From this, we now strive to optimize our patterning to gain the best algae generating output. This involves heavily studying the sun path and adapting various pods to its optimal properties, which in all hopefully develops a more randomized pattering layout. We also plan on studying different shapes in finding which would have the maximum exposed surface area to the sun.
From the matrices we developed, from the initial iterations, we learnt what parameter did what, then altered those with results that we favored. For instance, in our own definition, we altered the top scale factor altered the sizing of the 3D pattern top, making it smaller or wider. We favored having smaller tops as it looked more interesting and it exposed more surface area, thus we continued exploring in that direction.
For using the various growth stages of algae to produce colour, one of the idea we had is to have horizontal bands with the earliest algae batch at the top, and the most mature/ ready to harvest at the bottom. This is a logical arrangement as it grants maximum sun potential to induce large growth in the early stage pods; in addition, the mature pods that are ready to harvest can be kept at the bottom with the least sun exposure as it doesnâ&#x20AC;&#x2122;t need it. As suggested by the tutor, a patterning layout can be ap-
3) B.5 was a success for us in terms of model making. We followed the method that was used in our precedent and received no complication. From the models produced, they were tough, rigid and flexible; however putting downwards pressure on it did make it sag. To counter this, we are thinking of applying a thicker base surface, and support that with wires which mimic our intended support structure. 5) We were able to anticipate some of criticism from the
100
tutors. Due to a lack in time, we werenâ&#x20AC;&#x2122;t able to properly experiment with the various green algae light and how it affects our model both externally and internally. However the tutors did make us aware of considerations we did not think about, which will greatly help our design processes. As mentioned before, our presentation went well as it was convincing. This is due to conducting a lot of research in regards to algae and how the site can be used to harness this energy. In addition we spoke to the algae biofuel researcher Dr Ronald Halim and Simon XXX (he wanted to stay confidential), to understand how the process works and how we may utilize it on our site. We even proposed our design intention, in which they said was quite feasible.
8) We engaged in a lot of self-directed learning in the algorithmic construction, primarily in the reverse engineering aspect. We watched tutorial videos outside the weekly task, browsed through the grasshopper forum, attended the grasshopper help class and experimented with various definitions. Despite trying to make a rather simple 3D tessellation we went through a lot to develop the pattern we desired. This is all evident in B.4 and in my algorithmic sketchbook.
7) Referring to B.2, B.4 and my algorithmic sketchbook, we were able to successfully utilize grasshopper. Through the images and notes we put aside in this regards, we recorded what alterations we made to produce the iterations, thus demonstrating our understanding on how these changes affected the data flow in grasshopper to produce such results. Learning how the parameters manipulated the model, we In B.4 we were quite successful in reverse engineering our precedent. The patterning looked very similar; however there was one major difference. The major difference was that our precedent used equilateral triangles for paneling, where as we used right handed triangles. We were unable to produce equilateral triangles thus ended up using right handed triangles. During this process of reverse engineering, working out how to make the 3D protrusion was, the greatest difficulty was working out how to put that protrusion on the surface. Thus we experimented with a great range of surface divisions such as point list, triangulation, and boundary box to no avail. From conducting a lot of research we finally found our answer in the plugin Lunchbox, and successfully generated a similar surface pattern to our precedent.

ALGORITHMIC SKETCHES
This was one of tutorial task assigned to us where we were asked to make a random algorithmic model and apply it on the actual site. Initially I wanted to used what I learnt in tessellation and apply the VoltraDom definition on a surface I produced. Despite having no error displayed, I could not generate the VoltraDom pattern on to the surface. Thus I abounded that definition and applied the boundary box technique for pattern generation. For the boundary box I applied a simple cube as the reference model to simply see if this definition worked. The resultant transcended my expectation and created this beautiful mass of extruding arrays of rectangular prisms. I did not expect to see a basic cube generate this fabulous pattern. This is a case of purely coincidental design, again proof that with generative design, results canâ&#x20AC;&#x2122;t always be predicted and random changes in the parameters can generate unexpected results.

C.1 DESIGN CONCEPT CRITERIA First addressing the criteria and feedback from the interim presentation and design guidelines to properly devise a working concept.
INTERIM PRESENTATION FEEDBACK - Optimization and justification of pattern form and shape - Develope an overall form that responds to the site - Devise a colour layout based on the various stages of algae growth
Lagi Design Guidelines - Copenhagen has the goal to become the first carbon neutral city, thus the design must also be carbon neutral to reflect that goalâ&#x20AC;? - Be a public art installation that has large scale clean energy generation which can distribute clean energy into the electric grid at a utility scale (equivalent to the demands of hundreds or thousands of homes) - Prove that clean energy can be beautiful Have an ecologically positive impact over its life cycle Should aim to challenge/ teach the visitors on green energy
Site limitations - Southwest of the site has a water taxi terminal - There are plans to develope the water way to the south with houseboats - Boat access to the north must be maintained
108
Site analysis Based on the site limitations, the algae pavilion can only be built on the far east side in order to have access to water, and some parts of the pavilion sits in the water. This is optimal placement regardless as it gives full view of the shore. The people visit can clearly see the little mermaid on the opposite end, and enjoy the general water vista.

Design concept To create an algae pavilion where the algae is used to generate energy, generate aesthetic purposes, and inform the public about the potential of green energy. In terms of energy, the algae will be grown in pods decorating the top of the pavilion which will then be collected and extracted into lipid, carbohydrates and protein. The fuel converted from these resources can be used for cars, or further be converted into electricity. In terms of aesthetic, the various green hues of the algae will be taken advantaged of. Firstly, algae in mix with water is translucent, hence when sun passes through, it generates soft green light. The public can then bask in this light when visiting the pavilion, creating an surreal experience. Furthermore, as algae grows it becomes denser and produces darker green light. This can be employed having different stages of algae growth within the pavilion would produce an array of green hue lights. For educational purposes, we envision the algae making process to be visible to the audience, so they can understand how it works, how it can be used to make energy, and even have them make it themselves at home. The pods can demonstrate the ease of growth, and the different growth stages. The pipes can show the required inputs for growing algae such as water and nutrients. In addition, we plan to have some form of tank that collects all the algae and show the break down process, showing the lipid and biomass that is extracted. Aside for housing and growing the algae, the pods can also serve as an interactive item for the public as well. For instance, by having the pods on the ground, the pods can then serve as tables and chairs for the public to rest on. By having them on walls, the pods can then serve as climbing elements for the children. In response to the interim presentation, various tools from grasshopper will be used to analyses, improve and find the best design for the pavilion which also providing factual justification for their choices.
110
The primary design intent we envision is to have the audience bask in the various hues of green light as they walk underneath the large canopies.
The pods arenâ&#x20AC;&#x2122;t only used to grow algae, but can also be interactive pieces as well. With pods on the ground, people can use it as seats or tables, thus serving as a social interaction ground. They can be physically touched and closely observed, granting curiosity and discovery especially among children.
111
Pattern analysis
Finding the best pattern shape for algae growth
Total surface area Each shape pattern was made with the same width and height. The total surface area to find the shape that has the maximum area exposed to the sun. Thus the larger the total surface area the better.
Circular prism TSA: 0.351 m2
Square prism TSA: 0.354 m2
Triangular prism TSA: 0.368 m2
Tri grid prism TSA: 0.316 m2
Hexagonal prism TSA: 0.640 m2
The hexagon prism has the largest surface area out of the patterns, nearly doubling its rivals, thus grants maximum sun exposure for algae growth.
Shadow analysis The grasshopper plug-in Ladybug was used to determine each of the shapes pattern shadow qualities. To make this analysis as realistic as possible, the actual Copenhagen sun data was employed. With this analysis, the darker the area the greater the shadow, thus it can be seen that the hexagon patterns have the least amount of shadows. As opposed to the other shapesâ&#x20AC;&#x2122; patterns, each of the prisms in the hexagon pattern generates little amounts of shadow and does not overshadow its neighbors.
Verdict It can be concluded that the hexagon prisms are best suited as the surface tesselation for the pavilion. It has the largest amount of exposed surface area, generates the least amount of shadows, and does it overshadow its neighbors, thus is the shape that has the best exposure to the sun. Using this shape grants the maximum potential for algae growth.

Prototype development
Finding the best pattern shape for algae growth Inital surface form: Grid shell It was decided that grid shell with structural support underneath was the best choice for the pavilion building type. Looking at past examples, the general concept of grid shell generation looked similar to our part B pavilion design, provided a good base for different sorts of testing, could be altered with ease and contained the curved surfaces desired in part B. Thus to develop our surface, we used the Bubble form finding definition provided by karamba, and altered it to suit our design.
Boundary and points
Converted surface
Unsure what the overall shape of the surface should look like, it was decided to simply base it on the boundary of the Lagi site. This only served as the initial base and would later be altered and improved on through generative means of additional analysis plug-ins for grasshopper. With the outer boundary set to be similar to the Lagi site, the points were mostly placed at random intervals. These points serve as the center of the curved top (the highest ceiling point), thus some were place purposely near the edge of the boundary to create large entrances and wider openings for the public. Using voronoi to divide the surface, and karamba to apply forces onto intersection points of the voronoi, the surface was formed. With this surface, our hexagon and the pre-existing structural algorithm in the bubble form finding definition was applied to it to see what it would look like. The only issue with the pre-existing structural algorithm was that it generated triangular steel support rather than the desired hexagon shape, which of course be addressed.

Form development and solar analysis The form was further developed through a series of solar analysis. Using the prototype model as the initial surface, the grasshopper tool Ladybug was applied to check its solar potential. As shown in the legend on the left, with red meaning the most solar exposure, and blue meaning either little or none, the surfaces were then consciously changed to grant it as much exposed surface area to the sun as possible, until the perfect surface was formed. There is a perfect representation of Kalayâ&#x20AC;&#x2122;s two search techniques:
Series 1
(1) producing candidate solutions or consideration (2) choosing the â&#x20AC;&#x153;rightâ&#x20AC;? solution for further consideration and development. As such, the form was continuously improved on to generate the best outcome. During these changes, additional adjustments were also made for purposes outside best solar potential, for factors such as looks, interesting appeals, and realism (dimensions and height).

Resultant surface
The final surface derived from solar analysis testing. Primarily altered to have as much solar exposure as possible, additional changes were added to it to make it more realistic and interesting. Dimensions were constantly monitored to ensure the sizing and heights were as realistic as possible. Openings were purposely made much larger, and some to have overhanging points for better aesthetic qualities. Final change as mentioned were the orientation. The initial surface lined from east to west.
118
This final surface lies north to south. Primary reason is from the Lagi brief criteria. With external plans occurring on the north and south water exposure of the site, only the western boarder can be properly used. Thus the pavilion is to align with this border, to allow intake of seawater without it being in the way of the cityâ&#x20AC;&#x2122;s plans. In addition, it has much better vistas, as the pavilion incorporates the of the sea and the coast.

vv Structure analysis The primary issue with this algae pod design is the weight of the pods. Being filled with water each pod is extremely heavy, therefore the structure needs to be strong enough to support the entire weight. With this, the grasshopper plug-in Karamba is used to test the strength of the structure and find the correct dimension of the steel elements.
load force is calculated and applied on the members. The stress imposed by the load is repented as colours as shown on the legend. It is ideal to get as white as possible as it means there are no stress occurring on the steel elements, thus is able to withstand the presented loads.
Firstly all the steel elements are converted in circular hollow sections (CHS) as it is the easiest to modify and render as opposed to a universal beam. Then the entire
The diameter of the CHS is slowly increased by 1cm until the entire structure is close to being pure white. From this it was found that having 8cm in diameter CHS is enough to support the entire weight of the pods.

Hexagon structure system Structural layout
The steel hexagon members consist of 8cm in diameter circular hollow sections (CHS) connected to central steel nodes. The steel nodes all contain screw holes, and the interior of the CHS is threaded as well. This allows a threaded rod to act as a connection means between the rods and the nodes. This simple structure connection joints allow easy and quick erection. Furthermore itâ&#x20AC;&#x2122;ll cut down on cost and building time as it is extremely easy to manufacture, composing zero complex parts. However it is highly recommended for the joints to be welded together to ensure a rigid connection.

Day 6
As it takes algae 7 days to fully mature and be ready to be harvest, it has been decided to arrange the pods in 7 sections, each section being a horizontal band as represented in the diagram. The highest pods will have the initial growth stage, and as the algae grows per day, it shifts down to the lower section accordingly. Final and ready to be harvested algae will sit at the bottom pods. By having the algae more in that manner allows efficient algae growth. The starting

Day 7: Complete growth and ready to harvest
algae will need the most amount of light, thus will be at the top. The matured algae requires less, thus will be at the bottom. In addition, by allowing the algae to move downwards, means gravity can be used to push the algae down, thus no electricity is require for pumping purposes. From these reasons, assure that this algae growth arrangement is the most efficient.
125
Column design Rather than have traditional load bearing columns, it was decided to have columns that were part of the extraction process. Instead of being simple solid mass, these columns would be see through in nature, showing its role to the visitors and informing them how this algae process works. The column design is based on the single step oil extraction method for algae. In essence, the extractor which sits on top of the column, receives the algae and breaks it down using electric impulses and acidifying the water with CO2. The broken down algae, oil and water will shift via gravity into the plexiglas column tank below. Due to the nature of each element, the oil will float up, being in the top later, the water in the middle, and the algae biomass will sink to the bottom. Each layer will have a pipe output that transport the lipid and biomass towards the collection tanks, and the water back to the sea. Aside from having an educational purpose, the columns will have an aesthetic one as well. With 3 layers of extraction matter, shows 3 layers of different translucent colours (yellow, blue and green). As such the columns are extremely unique and would be interesting to look at. In addition, based on the algae output, the actual quantity of layers will change. For instance, if the algae processed had more water in it, the water section of the columns will be much larger, and the other two layers will shrink. Thus, the sizing layers will always change and will vary between each column. As such, the lack of conformity, and the translucent colours will be the primary appeal of the columns. Since the columns will be hollow tanks, they serve not load bearing purposes. To counter this issue, the structural performance will be relied on the hexagonal steel mesh instead which wraps around the columns. It continues the conformity of hexagon patterns, and also make the columns more appealing.

Solar and shadow analysis on final design Out of curiosity, the solar and shadow analysis was applied to the final design. The results were rather interesting and are discussed below
Solar analysis Despite being the same surface that was finalized in the previous solar analysis, having the pods of the same height provided different and rather confusing results. With the pods it showed areas of poor exposure to solar radiation, which contradicts the results of the first solar analysis. Furthermore areas without solar radiation are on the same surface as areas with solar radiation, which doesnâ&#x20AC;&#x2122;t make sense. The surfaces are generally flat with dips, thus the solar exposures should be conformed within the same region. Therefore the results from this test are rather misleading.
Shadow analysis This analysis also has its flaws. The results from this testing contradicts that of the solar analysis. It shows areas that receive constant shadowing through out the day, yet in the solar analysis, those areas still have solar exposure. This shows that careful consideration must be taken when selecting tools to conduct test, in order to evaluate real results. Regardless, from looking at this analysis , it is evident that there are many dark areas. This is problematic for a more efficient design. Being said, it could be an accidental design intention. These dark spots could be areas where algae doesnâ&#x20AC;&#x2122;t grow, breaking the green pattern conformity of the pavilion.

C.2 TECHTONIC ELEMENTS Fabrication
The pods unrolled on Rhino to be sent to the Fablab
It was decided for our prototypes that we fabricated a few pods using 3mm transparent perspex. Transparent perspex was the closest material to our ideal material of Plexiglas, and is waterproof, thus can be used to contain water with algae. As such it also grants us the closest visualization to what the working pods would look like. Being 3mm thick, it is very difficult to cut, so it had to be done with the laser cutter. A pod was unrolled in rhino
and copied multiple. As the material is 3mm thick, addition rods were made to fill the joints where the edges connect. We decided to go with a straight joint as opposed to the puzzle joint as suggest by other people. Despite puzzle joint being stronger than a straight joint, it has a higher probability to leak, which was why it was not chosen.
Conclusion of prefabrication Building the prototype was successful. It was easy to construct and deemed water proof as it had no leaks, Therefore no changes are required. When it was under load (from pushing it with our hands), the pod held itself, thus the joints provide sufficient structure and rigidity. As
136
such, the puzzle joint is not needed. These pods uses small amount of materials, are easy to assemble, works both structurally and as a water container unit. It can be mass produced with ease with low cost, thus this methodology can be applied in a large scale factor.
Perspex pieces cut off and aligned accordingly. 7 pieces are used in total to create a singular pod
Perspex pieces are glued together with zap a gap glue and held with tape as it dries. The rods were not needed in the end to act as joint fillers .
After the has dried, and the pod can hold its form, addition UHU glue was added in the joints to make the pod more water tight.
Once all has dried, the pod was filled up with algae and water. There was no leakage at all. It provided a realistic look to what our pods would look like, in which we deem satisfactory. The colour of the algae, the material and shape of the form all seem to compliment well with each other.

C.3 FINAL MODEL Rhino model for 3D printing Due to the complexity and small sizing of the pods, it was decided to only print the surface. Since the model was to be made in a 1:1000 scale, the each pods would be approximately 0.6 mm in size. The minimum threshold for 3d printing is 2 mm, thus is far smaller than what the printer is capable of. With the surface it required alterations before it could be printed. All gaps were filled, then the surface was offset by 3 mm to create the thickness. Afterwards the model was converted to a mesh model, exported as a STL file, and sent to the fab lab.
Structure The structure was not 3d printed as it was too small for the printer. The size of the steel members and the gaps in between were again much lower than the printers minimum threshold. Therefore it was decided that the easiest way to make it was to by the smallest metal mesh and mold it to shape. As such, the scale is not accurate but it does convey its intention, showing the purpose of the structure and what it may look like
3D printed model It took between 4 - 7 hours for the model to be completely printed.Once it was out all we needed to do was scrap off these supporting elements that held up the canopy. We were surprised at how it actually looks. I originally pictured a flat piece of flimsy plastic, but it came out great, properly showing the curved canopy elements. With its white creamy colour it even looked similar to the Sydney Opera House.

FINAL RENDERS
Plan
These final renders were created using a proper render software called ‘Blender’. This program offers greater flexibility in renderings compared to V ray as it allows better control of the lights, envrionment, and texture, thus offering more realistic renders. V ray generally generates cartoonist renders, and has little support, as it is only a plug-in, and not a full dedicated render program. The primary aim for these renderings were to make it as realistic as possible. Seamless texture packs were applied for
144
realistic concrete, water and grass. Water modelling was added to create the ripples. Surface reflection, light rays, gloss and refraction were all factors taken into consideration towards the production of the glass looking pods. The only issue we had was creating the desired green light hues for the interior space. The light that passes through the pods in the render don’t get into the interoior space. Regardless we were very happy with the overall output in terms of realsitically presenting our ideas.

C.4 Additional LAGI brief requirements Description The algae pod pavilion is an outdoor art installation that brings together the use of art, public space and algae technology. By harnessing the power of the sun and the local sewerage plant, the pavilion is able to grow algae, generate fuel and electricity, with the only output being filtered water which goes back into the sea. Aside from the fuel the algae produce, the pavilion also takes advantage of the algaeâ&#x20AC;&#x2122;sâ&#x20AC;&#x2122; translucent green colour. Since the algae are housed in pods which sit on top of the pavilion, sunlight filters to become various tones of green hue based on the maturity of the algae. These assorted lights ornate the interior space, generating a surreal experience for the visitors. In addition the pods also serve as interactive devices for the public. With the pods that sit on the floor, it can serve as seats or tables. The pods on walls can become climbing equipment for the children.
Technology use The technology used to generate green energy will be algae. Algae is a great energy source as it is easy to maintain, easy to grow, uses local resources (sea and waste water), and everything about it can be utilized. It is high in oil content (lipid), which can be made into biodiesel, the leftover carbohydrates can be made into bio-ethanol and the protein can be fed to plants or animal. Another great potential about algae is that it is stored energy. Once the oil and carbohydrate is extracted and converted into fuel, it doesnâ&#x20AC;&#x2122;t lose its energy value and can be used at any time. As opposed to electricity, that are no means of proper storage (batteries loses energy over time) and generally needs to be used immediately. Thus algae bring in the flexibility of stored energy. Chlorella vulgaris is the main algae species used for this pavilion. Reason being is that it is one of the most popular species used for growing biofuel as it has high oil content and is easy to maintain. However, other species will be incorporated such as bioluminescence algae to illuminate the pavilion at night. In terms of structure, it will be a simple screw in connection. The nodes and the hollow inside of the circular steel members are ribbed so a threaded rod can screw in between them and connect the nodes and member together. This ease of connection makes building quick and easy.

Environmental impact statement. The algae pavilion is extremely beneficial to the environment. It relies purely on local resources, the sun, water from the sea, and waste water from the local sewerage plant, thus being entirely carbon neutral. The algae also filters the water is it housed in, thus the only output from this pavilion is cleaned water which goes back to the sea. Algae pose no threat to the natural environment. Being a simple organism, if a disaster were to occur such as an algae spill, it could easily be cleaned up, or even be left alone where it can dispatch and deteriorate over time. Algae concentration has not short or long term ill effect on human health or the environment. In terms of material, plexglas is stronger, more durable and has a much higher lifespan than glass, thus needling less repairs and replacement. As such it has an overall lower embodied energy amount compared to glass. For the structural support, recycled steel will be used.

C.5 LEARNING OBJECTIVES AND OUTCOMES Our final presentation went relatively well. We received good feedback, but also a lot of constructive ones, suggesting we could have further improved, emphasis, or add on to our designs. Our strongest point was breaking down the component. How we got to our design through the various tools of grasshopper. There was more I wanted to do but due to time and computer restrictions, we were held back. The primary feedback we received were: 1) Expand the site. Take advantage of the land. Current design is too small, and people aren’t willing to walk that far to the pavilion. 2) Focus on the experience underneath the canopy. Show the different green light hue through the renders 3) Further take advantage of the site. Since pigs are one of the largest exports in Denmark, and one of our outputs are animal feed, we can incorporate a pig farm with the pavilion. 4) Explore other scales and arrangements with the form to see what other kinds of experiences that can be achieved The primary issue with the scale of our design, that I sadly forgot to mention in the presentation was the computer’s limitation. We had to make our design smaller than usual due to the lag it had with over ten thousand pods scattered on top. By adding more pavilions, or making it larger is going pass what our computers are capable of. Our current design is the maximum in which our computer and the university computers can handle. Therefore as much as we wanted to expand our structure, or add more pavilions we were at our limits. Even using the proxy tool provided by Vray, to ‘ghost’ the pavilion and make multiple copies is too complex for the computers to handle. Being said, I agree with the comments that we need to explore the experience that can be given with the pods. Make pods that can be tread on, tall pods for people to

walk in between, climbing pods, the possibilities are endless. Being said, the one dilemma is achieving desired outputs through generative designs. Generative design is to have an algorithm and by changing its parameters, create an interesting, random and unintentional product. By having desired aims does it not strive away from this approach?
Objectives: 1) Through this subject and learning about grasshopper and the array of tools it has granted me the ability to interrogate the brief with digital technology in mind. As shown in C.1, analysis tools can be employed to study the brief. Furthermore the brief can be used to formulize and algorithm to create generative designs. The guidelines and rules imposed by the brief can be parameters of the generative definition. 2) I was limited in the scope of design based on my computer skills. If I couldn’t make it, or if it was too complex, it would often be disregarded. Now with grasshopper, I have the solid understanding of performing complex task with ease. Designs that require vast repetitions, rather than do it manually, I can generate a definition for to perform such process. This is evident in my hexagonal pattern definition, in C.1, where it was used to create ten thousand pods of the same shape. 3) My skills in computation has exponentially expanded since the introduction of grasshopper. With tools such as ladybug and Karamba, I could perform testing that could be used as development and justification of my design matter. Even with fabrication, grasshopper makes this process easier. Even though it was not evident in our model, I have watched tutorial videos where grasshopper was used to create tabs for laser/card cutter assemblies. Again in the
past I created these tabs manually myself, but now it grasshopper, it makes this process much easier. 4) By developing a physical model, it informed us of how the model would look and sit within the site. With the model being 112m in length, we assumed that would be enough for the site. However once we placed the model in the physical site we made, it did look rather small. Therefore we should have tested more prototypes in regards to scale to generate the correct form. In terms of an architecture and air relationship perspective, it showed that despite being computer generated, the model did seem to fit seamlessly within the site, suggesting that pure computation design can be appropriate for real time living. 5) As mentioned in the past objectives, the ability to make a case of for proposal can be achieved with the analysis tools provided by grasshopper. For instance, to prove that the structure can actually support its weight can be demonstrated with the plug-in karamba as shown in C.1. Therefore various use of analysis tools can be used to provided justification in the design choices. 6) Part A outlines basic architectural projects that utilizes computational concepts to develop their design. Part B.1 and B.2 provides a deeper analysis by understanding how the tesselation pattern was applied to the project, and how the project was assembled through the use of fabrication. This led to Part B.3, which was reversing engineering one of the chosen projects, and then manipulating that definition to a pattern that we desired. 7) A basic foundation on understanding computational geometry, data structures and types of programing has been developed in this course. For this design, we went through various programing to achieve different design goals. For the generating of the surface, we learnt about using real time forces and applying it on a mesh to create point loads which pushes down on the mesh to create canopies. For the pattern, we learnt about applying a tesselation rules and manipulating in a way to create the shapes
we want. For the structure, we went through Karamba to understand the stress load it goes through in order to make a realistic structure that can actually support the pods. Various grasshopper analysis tools have been applied as well, with its data collected and used to further improve and justify the design. 8) In all, this subject taught me a lot about the advantages and disadvantages of Grasshopper and its various plug ins. With Grasshopper it allows the creation of generative design, leading to exciting unexpected results. Furthermore it can be used to perform repetitive manual task on Rhino, such as putting tabs on unrolled forms, or generating a sequence of repeating patterns. The primary disadvantage is the massive learning curve behind it. Things that seem basic may require watching lengthy tutorial videos, or downloading additional plug-ins and then learn about those. It also doesnâ&#x20AC;&#x2122;t allow desirable precise self control. For instance, if a small point on the grasshopper model needs to be change, sometimes a complex algorithm must be devised jus to control that small either. Thus often the easiest way is to simple bake it on Rhino and edit from there. Once ever once the object is bake, it looses the properties of flexible change given by its definition. Another disadvantage is the inconsistency and perhaps lack of formal evidence given by analysis definitions created on Grasshopper. This is shown in C.1, where the Ladybug solar definition contradicted it self. Despite and surface tested being flat, it showed one area to have full solar radiation and its neighbor with none. Thus one needs to be extremely careful with data analysis.

MULTI PAVILION
Responding to the crit Multi pavilion (above) SInce our model was too small for the site, it was suggested that we could have simply multiply our existing pavilion and align it with each other at various heights. This was done in the rendering above, but was extremely difficult to do. As mentioned before, just one pavilion was enough to slow down the computers, thus having five was extremely time consuming. Despite using the proxy tool in V ray to create a ghost of each pavilion, even though it helped dramatically, the computers was running extremely slow. As such, it was difficult to make alterations towards placement a height with the pavilions. Furthermore rendering with V ray took much longer than usual, being an 2 hour job. Regardless it does fill the site and to a degree it does look interesting. the pavilions need to altered more to break the consistency between them all.
Pig farm Another comment made was using pigs for our site. Since the pavilion can produce food the animals, it was suggested to use have pigs, as pigs are one of the largest meat producers in Denmark. Thus a simple pig farm was put in front of the site to see how it looks. It time was given, more work would have be applied to make this farm more realistic. However just from this simple render seems like a fun and interesting proposal to be taken,
