concept

- to amplify the experiences and metaphors of champagne and “the sound of excitement from champagne bubble in the cave” - to create “an enclosed space that overflows the listener in its center”

design

- folded plate structure inspired by Japanese mathematician and origami expert Taketoshi Nojima

inspiration

- the fold, as a multi-layered metaphor for the relationship between mind and matter, as described in “the fold: Leibniz and the Baroque” (1992), inspires plis/replis.

function:

amplify sound – act as a “loud speaker” - to create the “real-time analysis/synthesis audio system [which] creates a continually evolving sound environment” part of the concept.

site:

crayères of Vranken at the “Pommery” champagne factory Pommery, Reims, France - a Roman 18km underground system of corridors and caves - one of largest caves

constraints:

pyramid shaped cave height: 25m base: 18 x 18m

approach

CAD and digital fabrication site - pyramidal cave


how are you excellent job guys :D


step 1: paneling base circles /outside base circle

This group of commands sets the curve that has been created on Rhino and divides the curve to a set of points. The architect then used those points to get their x,y and z components to use them to create circles along the path of the curve with the radius of those circles as the x value. This is all used to create the outer base circles.


step 1: paneling base circles/ Algorithm to create inside base circle

At this stage the architect followed the Japanese Architect’s origami algorithm to create the first steps for the inside base circles, he creates the inner circles in relation and using values of the outer base circles as well as the folding angle. He divides the points into two sets of data.


step 1: paneling base circles/ Algorithm to create inside base circle

The final folding depth is defined by the distance between the two sectional curves. The architect used the Amplitude component to extend the circles in the x direction and he reversed and moved the points to create his intended relation between the two sets of circles: the outside base circles and the inside base circles.


step 2: points organization This part of the definition is used to set and organize the points of the base circles that will be used to create the surfaces of the folds. He divided the final surfaces into two groups by type that he then uses them to create bottom and top points for the surfaces connecting between the two sets of circles.


step 3: surface from points

In this part of the definition he used the set of points created by the cull pattern to create lines that create the surfaces of the folds, this is repeated to create the surfaces of the folds in all directions and loft is used to connect between the whole surface.


It is clear that there are different divisions for the grasshopper functions that the architect has used. There is an analyses definition, however as we were not able to find it, we looked for alternative for software that can be used for Acoustic Simulation.


Acoustic Analysis Alternatives Pachyderm - Rhino plug-in - uses common geometrical acoustics algorithms within the context of the Rhinoceros geometry system - recommended for use in study, or as a supplement to proprietary geometrical acoustics packages - features - set an acoustic source and receiver - assign materials - air conditions available as parameters Buzz v.0.1 Grasshopper definition - acoustic simulation currently only conducts geometric acoustic analysis -upcoming components include - receiver to record impulse responses - convolution engine to listen to design solutions in pachyderm real time -wave-based solver to more accurately explore diffraction and scattering behaviors


ODEON Acoustic software - for measurement, simulation and auralisation - imports 3Ds and DXF file formats - essentially same as others but results include - fast and global estimate of reverberation time - detailed results of acoustical parameters and auralisation option for a single or multiple receivers - map of room-acoustical parameters and statistics for the grid receivers - fast displayed grid map of direct sound to check the loudspeaker coverage before the room acoustical parameters are calculated - 1st and 2nd order reflector coverage. - dynamic display of raytracing from selected source - interactive display for visualisation of wavefronts to demonstrate scattering, flutter echoes, focusing and coupling effects I-Simpa (GUI) Graphical user interface - for 3Ds file formats and Pythons scripts - open software, each user can integrate its own numerical propagation code, develop its own functionalities within the interface for its own applications - essentially same as others

fabrication process - All panels were cut out from Aluminum/polyethylene composite sheets on a CNC router - Parts were cut using a V-shaped router which allowed the panels to fold this rigid material along designed paths - Alupanel is an aluminum composite of two 0.3 mm Aluminum sheets, sandwiching a 3mm Polyethylene core, and weighs only 3.4 kg/m2.

285 flat sheets were cut out (3 x 1.5 m)

the sheets were precisely folded 2535 times

primary and secondary steel cables.

simulation

- acoustic simulation should be fed back into design process and used in optimisation but the definition used could not be obtained. suggestions have been provided

design comments

- site constraints could be better integrated - no simulation/ justification for scale (10 x 10 x 13m ) - lack of interactive space

use of parametric tools

- parametric design provides an invaluable link in connecting tangible disciplines such as engineering and architecture and less tangible fields such as math and natural systems. In this example, parametric tools have been fully exploited to translate an algorithmic definition into a tangible structure and a specific user experience

student outcomes

- learnt about analyzing and solving problems in grasshopper - learnt about digital fabrication techniques
