A. Exoskeleton Component

Through exoskeleton component, there are a lot of form variations due to the indexes about process of mesh forming based on the initial curves are alternative.

C. Stretch Ends of Orginal Form

Stretching the ends of the original form to explore the relationship between different components. The variations of the outcome forms are limited, as lack of constraint, although the appearances of forms are quite dynamic.

CASE STUDY 1.0 MATRIX

As our design would focus on creating minimal surface structure, we take the Green Lava Void as the case to explore the formal variations and nature of such structure. In this case, the designers adopt

Kangaroo plug-in and exoskeleton, which is can interactive simulate, optimize, as well as find form of the structure, to control the stiffness, pulling and contracting of tensile strength.

C. KANGAROO

Variation of this project though kangaroo plugin is not so suc-cessful, since some are points while others are the whole curve in the membrane. Therefore, we take create our own form to explore with the Kangaroo. Through these experimentations, we have a better understanding of the relationship between refer-enced data and the forms, which help a lot in the further design process.

Technique: Development CASE STUDY 2.0 Matrix

Digital Prototype 1

We apply the triangle solar panel pattern to a curve surface to see how the unit panels fit the surface an-gle. This aims to test the performance that the small solar panel fixed on large-scale surface for the further design. And the digital outcome proves the practical-ity and aesthetic about the solar panel installation.

Prototype 2

We gain the inspiration of the RMIT Design Hub to explore other possibilities for the LAGI project with solar panel system, in term of both pattern and geometry structure. In this prototype, we used the square solar panel patterns to increase solar panel surface are applied. And the turbo shape pattern for natural light transmission are adopted to save energy use for the project it self. However, as its geometry shape would cause some part of solar panel can not receive direct solar radiation, although the surface of solar panel increased, the efficiency of energy collect doesn’t not improve distinctively.

Prototype 3In this prototype, we tried to approach to new pos-sibilities of finding the form. We explored the geom-etry form and gain this result form.

Prototype 1

We use the grasshopper tools to form the structure that based on the waveform shape for further solar panels installation. This structure provides the flat surface

for paneling. The solar panels can be installed on the grid. However, its heavy lattice increases the dead load of the structure, which may lead to collapse. Moreover,

the ball joints will increase the cost of construction, as each individual joints need to custom-ized to fit the pipes. Therefore, we abandoned this prototype.

Prototype 2

Then we tried another prototype with grasshopper. This prototype also remains the characters of last prototype, which has the flat surface paneling. In addition, comparing with the last heavy lattice structure, it reduces the

dead load of the structure. This improves its stability and save the construction cost. Furthermore, this smooth form enhances its aesthetic sensibility. Moreover, we tried to install solar panels on the whole roof surface of

the construction to maximize the green energy that can gain. Nevertheless, this will increase the construction cost and block the nature light, which will need extra energy for lighting.

Prototype 3

To keep the characters of last prototype, such as flat surface paneling and aesthetic sensibility, we keep the form as last prototype. But in order to avoid the natural light blocking issue, we replaced some solar pan-els into glass randomly. This means the roof will no longer covered by the solar panels, due to high cost and the natural light blocking. It is more transparent than previous a prototype, which allows more nature sunlight to light the interior during the daytime. This is more green efficiency as it save the energy cost on lighting, although it reduces the energy generation due to fewer solar panels. However, this prototype adapts the complex curved framing ,which will lead to the hardness to manufacture and increase the cost.

Final Model FRAME Fab Lab

Fabrication Process

At first, we decided to use the 1:200 scale to do final model for more clear expres-sion of our design. The final model will be around 1.3 meter long, 0.8 meter wide. Then we modified the digital model in rhi-no. The whole frame structure was divided into 4 parts, as the material size in Fab Lab is limited. Then use the Boolean Differ-ence tool in Rhino to trim out the vertical beams on the each horizontal beam. In this way, we gained the horizontal beams with hollow to let the vertical beams fit in, like the waffle structure. Then, unroll

these beams label them and put in the file with the Fab Lab formal for laser cutting. Once the got the laser cut piece, we insert the vertical pieces into the horizontal ones and form the roof frame structure. Then put some color polystyrene sheet into the square grid based on the thermal map and cover a clear layer over the frame structure to indicate the EFTE membrane. After set up the columns on the site model, the whole roof system including paneling was placed on them.
