Background

For project 2, I modeled the skin for my final study. The topic of my project is a electronic music center. This is the image of my project before, now the facade looks a little bit boring. I want to make it relate to both the program and context, so I decide to redesign the facade of my building. The analysis was conducted through grasshopper and Ecotect, which provided data used to determine the size and locations of the openings on my facade.

Ecotect Analysis

To prepare for Ecotect analysis, I created the basic shape of my building in my building. Then I converted it into mesh in grasshopper.

Then I imported the mesh into Ecotect where the insulation analysis was conducted. The yellow areas are where heat loss is minimal and blue is where heat loss is greatest. The more subdivisions I created, the more accurate the data.

Forming the Panels

I pick up one surface from my project and did a research based on this surface. I divided the mesh into a grid. This grid can be controlled in both the vertical and horizontal directions. These divisions come from the first phase.

Then, I created the paneling by multiplying the points on the grid and generating a list of random numbers that would select what would be solid/void.

The selection is based on a percentage that is controlled with the slider.

I’m trying to do one more step .I want to divide these numbers into two groups based on the heat loss. The area where the heat loss is small will be void, the area where the heat loss is large will be solid. However, the problem is all numbers are the same. if it works, this step should replace this process. 

Using grasshopper, the thickness of the panels can also be adjusted.

Description:

The Louvre Abu Dhabi Museum, designed by Jean Nouvel, aims at creating a welcoming world which associates lights and shadows in a peaceful atmosphere.  Its objective is to belong to its country, to its history, to its geography.  Its key way of achieving this was through the roof’s unique fractal perforated pattern.

Each of the cladding layers, including the structure, is based on a simple base pattern combined to

create the final effect.

After analysis, it is clear that all the fascinating effect coming from the overlapping of several different layers with the same pattern. The only difference between these layers is the rotation of these patterns that makes the effect of interception.

Process:

The process of creating the dome starts from a mesh. Weaverbird is used to abstract each edges of the mesh. Then I concert these lines into springs and make the mesh be fed to a kangaroo definition.

The naked vertices here is to separate the points into two parts, the first one is called naked points, which are connected to the anchor points in kangaroo, the second one is clothed points, which is connected to the force point

By giving kangaroo a U-Force node in the positive Z direction. 

The mesh takes the shame of a dome.

In order to manipulate the dome, the dome has to change from mesh to surface, the first step is to extract the longest curve line from the mesh dome. 

The second step is to move it to both sides of the dome to loft a surface.

Since the perforated pattern comes from several layers overlapping and rotation. So the surface will be copied and rotated.

The last job is to attach the pattern on these surfaces. There are three steps, one is surface box that divides the surface into boxes. 

Second step is make the basic pattern from 2-D to 3-D. 

The last one is morph that attachs the pattern into surface boxes.

The last step is to trim the surface edge to make it the same as the original dome. Use the solid difference battery to get this job done.

Add inner buildings within the dome.
