CRITERIA DESIGN 59
Architecture is moving towards sustainability due to the natural resource over-consumption and damage caused by human. It is time to begin to think about how to utilize our design to fit in the future and being sustainable in order to avoid the future generation not being able to survive with enough resources.
It’s fortunate to see that human begins to realize the importance of the biological entities. As we are not the first one to build houses for youth and to social/work within large commnity. The ecological organisms are now been awared by human due to their long-lasting sustainble existence. In Ted Talk, Janine Benyus clarified that the truly sustainble model has been in the planet over long periods of time is the ecological world. In the past millions of years, their existence didn’t effect the surrounding environments negatively.
Biomimicry is used in current design flexibly due to distinction of each biological characteristics. It refers to nature as model, and it is a new science that studies nature’s models and then imitates or takes inspiration from these designs and processes to solve human problems. It not only mimicks the forms of the natural appearance, bu also imitates the biological behaviour to create sustainable outcomes.
Therefore, I would like to use Biomimicry as the field of my design. I will integrate this design term with the biological characteristics to provide sustainable opportunities for Merri Creek.

DESIGN
The ICD/ITKE Pavilion 2013-2014 is a good example that shows how Biomimicry influences the design implication&opportunities and the fabrication.
This project was inspired by the shells of beetles, in order to develop a light weight panelized canopy. Beetles are winged insects that have tough outer wings like a shield. All beetles have two sets of wings - their body is covered by a hard shell (called an elytra) that protects the thin wings underneath. Therefore, the design mimicks the biological characteristic of the shells of beetles. The outer shell made by steel frame (hard shell) is strengthened by the carbon fibers (thin wings underneath) so that it results in a stable structure that can withstand the mechanical stresses.

FABRICATION
The project took this biological production process to create the fiber-reinforced structures by using KUKA robots to wind glass and carbon fibers around the thin steel frames. The research pavilion also tested the limit in lightweight construction as they used a robust double layered construction that accounts for potential extra loading through the facade system.2 They used the coreless winding technique to reduce the mold consumption, therefore material effecient.

3. Seroussi Pavilion I Biothing arch20, 2007) <http://www.arch2o.com/seroussi-pavilion-biothing/
DESIGN
The Biothing Serioussi Pavilion is a ground pavilion project located in Muedon. The design was inspired by the local sculpture habitacles. It is a structure seen as grown from self-modifying patterns of vectors based on electromagnetic Fields. 3 The project mimicks the ecological generating process and apply the idea into the deisgn. Therefore, the dynamic nature of the design reflects the parametric relationship between parts and the deep ecology of algorithmic relationships.
On the other hand, the concept of the project has the idea of indeterminacy to integrate in the structure in order to organize the spatial pattern and generative fabric. The computational method provides the advantage to the designers to achieve the complexity and the self-modifying patterns. The project is a good example of using computational design to create generative design.
PROGRESS
The initial computations (arrange the attention and repulsion) were done in plan view then lifed via microarching sections. At the meantime, the designers applyed different frequencies to create the complex and diverse pattern. The branch curve from the divided point can be extended or growed in different way based on the variable field condition. To allow for local adaption to site conditions, additional features were added to the generating script. Therefore, the microbiological structure is fromed and constructed by the complex line charge.
This project attracts me as the pavilion has a sense of separation due to the volume is defined by line charge but it is also an organic unit due to its clear structure.

SELECTED OUTCOME
B.2Selected Criteria
I’m planning to design a structure (mimicking the function and form of the Marine Microorganism- Diatom) suspended instream near the waterbank of the Creek from Merri to Northcote. The brief is to create an instream structure which has the function of biomimetic filter to increase the level of turbidity of selected site so that light is able to penetrate the waters to permit photosynthesis and sustain food sources for fauna from in-stream and surrounding wetlands. Therefore, my selection criteria is the structure that has smooth and fruid form in order to not only allow the fishes to swim through underwater, but also provide the birds from wetlands to drop by.
The 4 terations that I chose all have fruid and smooth forms.
Design PotentialThe iterations might be helpful for generating the fruid form which I would attach in the Creek. Thus, the material to construct the structure must be waterproof. However, as the itertions are mostly in point/line charge, the consturcting process would probably be a problem. I might use powder printing or use flexible materials such as polyethylene or fibre.
CRITERIA DESIGN 75
This shape formed by line charge seems like the structure of the marine microorganism which is interesting. However, it is rather to be seen as pattern in stead of an organic structural unit.
The shape is quite organic and flexible. I might be able to use this kind of swirling and fluid shape to mimick the swarm intelligence and it might achieve my design proposal of building an underwater structure.
The shapes in the cluster at the central part appears like mountain. Thus the whole structure looks stablized.
The line charge component enables to define the boundary and make a clear arrangement of the elements. As the lightest curvy strips appear as the primary load bearing structures and the parts growing from the central points seem like the secondary structures, this would be helpful in constructing the physical structure.

I chose this particular project as the reverse engineering because this might be the solution to my conceptial idea which is to create the filter structure that could create low water turbidity.
Diatom has its own natural nanotechnology, I’m interested in exploring the properties of diatom biosilica (structural, chemical, optical and mechanical), and their potential for nanotechnological applications (structural membranes and nanofabrications).
From Figure5, the Diatom shell is composed of structure is extremely sophisticated silica 10 to 50 nm hexagonal pore to form the wire mesh structure. This kind of complex structure can stop the light to escape. The grain incredibly algal crust can not only to enhance the hardness and strength of the diatoms, but also provide suspended mechanical properties, therefore improve the transport of nutrients and adsorption, adhesion, physiological function, and prevent the harmful substances to get in, and eventually enhance the light absorption rate.

FORM
I’m interested in the swarm form that have biological performance. Refer to the site, I may use this form as stream track and adapt this winthin my design.
The shape here has a tunnel like form which could be used as the volume of my design. On the other hand, the fauna in the stream could also swim across in it.
The outcome produced here has the pattern of the Diatom Cell wall which could be adapted into the final design pattern. The outline of the panels here has clear strip structure which reminds me of the hinge connection and the truss structure.
This volume produced by kangaroo plugin is more desireable than the iterations in part A as it is more buildable and it has the freeform track with the opening space that allows fauna swim across. The complex pattern on the surface would be able to filter the dirt which is adaptable with my concept.

CRITERIA DESIGN 105
In Diatom interior structure, the connection of the Diatom Shell has a appearance of teeth so that I was inspired to mimick this biometic structure with two section which can be connected by the teeth expansion joint. The structure is good in compression and provide support across the expansion void.This type of joint could hold for large movements of up to 2000 mm. Refer to the material, I used 3D printing-PLA to reemerge the biometic structure instead of machinary joints made out of steel which is expansive and high weight.
106 CRITERIA DESIGN
As I aimed to mimick the double-layered Ditom Filtering Function, I created this model by using 3D printing. The model has two layers in which one has single round pore, the other has denser pores in order to block the dirts or rubbish flowed in the water. 3D printing would not be the final method to construct my design, however, I’m enable to test the function of double layered structure.

HINGE CONNECTION
This is an imitation of the hinge used in the Parametric Screen. I built a hinge with two ends fit together and a pin secures the join. This hinge will be on the underside of the panel to bend in direction and help spread the loads outwards. A small locking pin is required to secure the other side to the hinge and stop any wobble or flex.
In stead of screwing into the pnael, I made 3mm hollow section in the middle of the hinge in order to notch the thickness of the perspex panel.

112 CRITERIA DESIGN
After modelling the 3D printed hinges, the result turns out as failture. As I chose PLA as 3D printing material, the surface is quite slumpy and rough so that the pin didn’t match the join. Therefore, I used steel hinge pin which has to replace the 3d printed pin. On the other hand, the join was not very flexible due to the rough edges or the frame. Therefore I need to remodel the hinge joint or I might use the manufactured metal hinge joint.

RIGID CONNECTION
In stead of using the previous Hinge Connection, I tried to use triangular joints with bolts and nuts to screw into the screen panels to create rigid connection to join. Laser cut and 3D printing allowed me to create precise panels and joints. The extended part of Joint 1 enables the wire or fiber optic to fix inside the joint. In this stage, I’m still trying to test the possibilities of connection.

B.6. TECHNIQUE: PROPOSAL
L,
Merri Creek on World Wetlands Day indicated that if healthy water levels are maintained, the flood control and habitat preservation could be maintained in order to sustain the biodiversity. In recent years, the creek here appears to be in condition with few signs of physical pollution (plastic, rubbish), and the bio-species decreased due to the water turbidity. From my observation, the creek seemed very quite and lifeless.
My design intention is to achieve low levels of water turbidity so that light is able to penetrate the waters to permit photosynthesis and sustain food sources for the fauna either from instream or from surrounding wetlands.
In order to achieve this goal, I would like to design a noticible structure located in the spot of the upper stream near Rushall by mimicking the function of Diatom-(1: Bio-mimetic Filter-material & internal double layer cell wall structure 2: Photosynthesis-Grid pore).
Victoria’s unique rivers and wetlands are home to millions of species. They sustain our way of living and our future, therefore we need to better manage our actions and reduce negative impacts to nature in order to interact and communicate with the natural environments.

B.7. LEARNING OBJECTIVES & OUTCOME
CRITERIA DESIGN 123
Part B study allows me to get more familiar with using Grasshopper, I feel the design out come could be potential and enhanced by computation method. The computer program is always the best friend to help with the design process.
The computational tools not only for designers to model their design but also enhance the design by the process of modeling it as there were always potential design possibility during the computational process. Through the reverse engineering process, I was taught to find the design difficulties and solutions. Prototyping is great method for testing the reality of the design physically. It’s important for designers and architects to understand the way of achieving design in reality. No matter the prototypes are failed or succeeded, the process is more significant as it gives great opportunity to adapt and develop the idea.
