the exoskeleton of a invertebrate. This is known as biomimetic.

The second is to mimic the function of a biological organism; this would include the modeling of a chemical reaction or the biothing project looking at the movement of magnetic fields. This is known as biomimicry.

biomimetic generally looks far down the evolutionary chain to early life on earth, due to the simple organization and the fact that complex evolution has not yet taken place. It will generally be composed of fractals, voronois and hexagons. Nature favors these geometries due to the large surface area they provide. Hexagons are repeated in nature over and over on all scales from a benzene ring to beehives.

biomimicry,

bios, meaning life, and mimesis, meaning to imitate

biomimicry is to look toward nature for solutions for design, with the understanding that nature has been undergoing the design and refining process for over a millennia.

biomimicry is the umbrella that covers two different categories:

The first is the imitation of structure, this could be on the micro/atomic scale and the arrangement of the atoms, e.g. an abalone shell which is formed from the stacking of a hexagonal grid of the same substance as chalk, or the macro scale, e.g.

Selection Criteria

- Using the algorithm to create complex geometry. This geometry is then translated into a different from though line work.

- The translation must contain the same elements of symmetry as the original form. However, Could be misunderstood form the wrong angle, leading to misinterpretation by the viewer.

15-From this angle the form can be understood as an overall, the line work highlights different aspects of the geometry.

17- Is the propagated iteration of 15, from this angle is almost doesn’t relate back to the original form, though interference of its self, leading to misinterpretation.

25-The line work has created a woven pattern, the lines are at strong angles interlacing with each other highlighting some aspects of the original geometry.

29–The propagated iteration of 22, containing four units only one is directly identifiable to that of 22, leading to

with no holes, this was successful in removing the holes but not in producing the correct structure (fig b.3.3).

The bowoss pavilion was a project conceived and constructed at the school of Architecture at Saarland University in Saarbrucken, Germany. The wooden shell structure is bionic inspired, utilizing minimal material in its construction, It is also a structure that is responsive to natural light, as it allows light in from every angle. This is due to the orientation of the ellipse on the surface for the structure.

The first attempt to reverse engineer the project was analyzing the surface pattern, in doing this the repeating unit was then made in grasshopper and propagated across the surface though the box morph function, this is seen in figure b.3.2&3. This was unsuccessful as the surface had gaping holes in the surface. The original panel was then re-modified to panel across the surface

The first two attempts of reverse engineering were unsuccessful, leading to starting a new method of working with the data flow. This third method which is seen in figure b.3.5, was done by splitting data, moving and recombining this data in order to create the pattern. This was successful when looking at the grasshopper model and the pavilion itself.

41- Has only rigid panels on the edges and spine of the shell, connecting these is a rib cage like structure which is composed of pipes interwoven into each other and draping into the pavilion. This removes elements of rigidity from the form of the pavilion while still keeping the base elements of the form.

47- This iteration highlights the frame of the structure, which is the structure itself.

spheres into my design using iteration 47 of b4. The spheres geometry has been approximated into a form that can be fabricated. Of all three iterations number 50 fits into the principles of iteration 47,being that it is merely a frame for the sphere itself as the iteration is mearly a frame of the structure.

Considering the Lagie brief, I wanted investigate the different methods of energy generation by solar.

Solar spheres were designed by barcelona-based architect Andre broessel, they are composed of glass and water, fully weather proofed and due to the nature of construction are 35% more efficient than traditional photo-voltaic counterparts. The spheres also offer an interesting opportunity of designing in grasshopper purely due to their own geometry.

My last three iterations look at a method of framing the

The prototype frame was made by hand. Each element of the frame must be grooved in order to join the panels together, When inspecting the case study o the bowoss pavilion and its construction method of joints on the back that have been mitered and CNC routed. The joints as seen in figure b.5.3 have been sanded down to meet each other on a 45 degree angle. This was a successful method of producing the frame however for Lagi the frame would be fabricated though CNC.

This system of having an internal frame in which the panels are mounted can support itself and the spheres are held in place as they are a perfect fit.

3. Solar Sphere.

The sphere is inserted into its frame in the panel, this is then treated as one unit. The unit is then assembled on to its structural frame.

The LAGI site its self is large, for the site I wanted to divide it into parts to induce circulation of users through it. To do this the structure was divided into its two assembly parts. The solar spheres where to be placed separately on the site on built up land fill, this is done to bring attention to the role they play in the structure. Then people could sit, walk & touch the spheres as to have an interaction with them and gain understanding of their purpose on the site.

The frame or panels that hold the spheres in the structure are placed parallel to the spheres on site used to create an under pass on the site. This dark environment is linking back to that of the industrial surroundings of the site, the use of steal for the frame and concrete for the bass to bring a cold chill to the user as this part of the structure is not converting energy from nature.

The structure its self is placed at the far south western point of the site. This is done to frame a view of Copenhagen for the user as they exit the structure. The overarching dome with the spheres in place , allows maximum light onto the sphere so that they can harness the energy from the sun and given their transparent nature allow light into the pavilion.

b.7. Learning Objectives and Outcomes

During part b: As biomimicry is such a large field you can find a biological model for everything, it just depends upon what you want it to do. It does not have the restrictions of sectioning or perforation as a research field. Due to this large field there are many solutions to the integration of the solar spheres into my design, but question is whether to let the structure dictate the form or let the spheres dictate the structure. In the later part of part b I have been walking the line between these two possibilities. During part C, I will be looking toward the solar spheres dictating the structure and looking into structural performance to find the answer and concentrating on the detailing the joints which will connect the structure to the spheres and how this is also accomplished.

The site plane proposed in b.6. is highly ordered yet vagrant, the separation of the parts of the structure into the site does not induce the circulation and movement intended. During part C I will be taking a new approach to the site plan, revisiting the selection criteria form b.2.Case study 1, looking at abstraction randomization & misinterpretation of the spheres onto the site to induce movement of the users though experience of their visual sense.

Week 6

From this week, learned how to control different offsets from the surface, abstract data from the existing surface, to control the size of the objects that would then be lofted.

Week 5.

Used the surface mapping tool then was able to isolate circles of a specific diameter and control and manipulate this data using the tools I learned in week 6.
