Part B: criteria design


B.1 Research Field

After comparing and discussion about all material systems, our team decides to choose strip and folding as the starting point of our design project. We research on some precedents of strip and folding and found that strips can form into variable unexpected shapes and spaces. Strips could be bent, fold, twist etc. For instance, changing the direction and degree of folding strips will create vary unique outcomes. And the use of strips can produce very beautiful voids in the surface like ICD / ITKE Research Pavilion 2010 (Fig. 21.22) and Double Agent White by Marc Fornes / Theverymany (Fig. 23).


These gaps can let the lights through and cast stunning shadows. Strip also allows more air through the entire project. According to 21 years weather record, the average annual wind speed for LAGI design site located in Copenhagen is 20km/h21. It is possible to use of wind to generate energy since the wind speed in Copenhagen is relatively high. We also want to add some special characteristics in our design to attract people. The first idea come up with is when the wind blows gaps there will be some sound. So what we are going to do is develop a technique that

makes the project emit different tones sound like singing. The strips may be subject to bending forces, so that it is important to choose a stable material and also full of tension. There is a range of materials that we can use such as metal, composite plastic materials, plywood. ICD / ITKE Research Pavilion uses plywood strips for the structure since they can be bent22. Plywood is suitable for this pavilion as it looks soft and creates a quiescent environment for people. Therefore, choosing materials also depends on the purpose of a curtain project and needs to response to their site.

Reverse Engineering FLUX

by CCA Architecture/MEDIAlab

(Fig. 24.) FLUX installation by CCA Architecture/MEDIAlab.

We choose the FLUX installation (Fig.24) was designed and assembled by a team of California College of the Arts faculty and students. It was used as display boards for an exhibition “FLUX:Architecture in a Parametric Landscape” held by CCA Architecture/MEDIAlab. FLUX meaning “continuous change or movement

is an appropriate appellation for the current state of affairs in architectural practices that try to reconcile the need for iterative or evolutionary design procedures with the ways in which we produce architectural environments23”. The FLUX installation applied advanced digital design technique to create the form and

also help with fabrication. All of the vertical MDF (medium density fiber-board) ribs and horizontal HDPE (high density polyethylene) panels of the FLUX was generated by the grasshopper definition. And it is easy to assemble and disassemble because every part of the project is distinctive and numbered in order24.

Reverse Engineering Grasshopper Process

1. It is crucial and fundamental to determine section shape of the FLUX, because this shape is the basis of the twisting-structured project.

2. By utilising script ‘Area’, a central point of section shape is discovered. From the central point, a line is generated which is regarded as the centre of rotation. By moving multiple section shape along x axis, a base form of the FLUX is created.


3. After generated the basic shape of the FLUX, 3D rotation is applied by using the central line as the axis of rotation. To make the model more similar to the original FLUX installation, the direction and degree of rotation should be similar. Therefore, the “angle” command in “Rotate 3D” needs to connect a “Graph Mapper”. By this step, the model has the twist form.


4. In order to obtain a more actual reverse of the FLUX, surfaces of the boundary are divided into two parts: rigid structure and the surface lofted between the structure.

5. For the surface lofted between structure, lists of faces are scaled. In order to ensure all the faces are scaled in same direction, Planar is used. After extrude, the series of faces are cull indexed.


6. The final reverse engineering of Flux is finishing by joining two parts of the boundary together.
