ARCH 655 Final Project

        

        

For the Final Project, I try to create a pavilion with its surface patterns controlled by insulation analysis data of different locations.

1. Create Basic Form with Kangaroo

I simply drag some of the anchor points to make the form more interesting.

2. Use Ecotect for Insulation Analysis

I export the mesh to Ecotect,and get the analysis data back to grasshopper. Then show the result on rhino interface with mesh colors.

3. Use Ecotect for Sun Path & Sun Rays Analysis

This part is almost the same with insulation analysis, except I get to control the date and hours of the analysis.

4. Remap the Data and Find the Corner Points of Each Faces on the Mesh

I use remap to make all the radiation data from 0 to 1. And put all the corner points for each faces on the mesh into different groups.

5. Use 'Recursive Squares' for the Surface Pattern

6. Use 'Mouth' for the Surface Pattern

7. Conclusion

This may be not quite useful yet in real world architectural design, but it is an interesting experiment. Hope it would contribute to professional practices with more analysis and research.

1. Project Information

Pavilion / stage for “Nature Concert Hall” is designed as an art object that unifies all 

main atmosphere making components of the event – space, light, video and music. 

Under the roof of the pavilion is a place for academic symphonic chamber orchestra 

of 20 people and Nature Concert Hall music band. The elevations of the pavilion 

serves as a screen for video and light projections. Architectural volumes are referring 

to existing elements in the nature. The structure of the pavilion is made in a way to 

reduce the amount of points touching the protected biotope meadow.

 

2. Design Objectives

The design purpose is to learn about parametric model while constructing the 

pavilion by Grasshopper in Rhino environment. The main challenges include the 

building the structural frame and controlling the rotating curtains. To make the 

model efficiently and correctly requires a better understanding of data tree structure.

3. Build the Parametric Form

3.1 Construct the structural metal frame

Begin with a square, I get the base lines for the structures by moving and finding 

midpoints. All the work is done by grasshopper, which allow me to change the 

dimensions of the structure.

    

Add more details to the structures by connecting the top and bottom ends.

After get all the structural frame base lines,  I construct the section for each line, 

and give them volume to make them look more realistic.

3.2 Construct the fabric shade roof

For the roof, I pick up the structure lines as edges, and get them to form 8 triangular 

by changing the tree structure of the data. Then use the boundaries to form the roof 

surface.

3.3 Form and rotate the curtains

First, I get the all the curtain surface by extruding. Then divide the surface by UV 

numbers and get the basic points on the corners each curtains.

To follow the original design, each curtain are formed with the top two corners fixed 

on the structures and the bottom two corners not fixed on the structures and ready 

to be rotated.

Following steps are the keys for controlling the rotating curtains. The top part is to get 

bottom line of the curtains and to rotate these line with a series of degrees around the 

certain axis, which are set from the midpoint of each bottom lines and points to the Z 

direction. And the bottom part just to get the top lines of the curtains  with the right 

tree structure.

The last step for the rotating curtains is to simply loft all the full curtains with the top 

and bottom lines. The rotating degrees and the number of curtains being rotated can 

be changed by the sliders.

3.4 Construct the base platform

The base part is extruded by the same square that forms the whole frame structure.

4. Create the Physically-Based Part of the Model

Create a mesh plane and add spring force and Z-direction U-force to it with the 

points on boundary and diagonal as anchor points. Then attach these anchor points 

to the roof structure to get a physically-based roof shape.

    

5.  Analyses

Curvature analysis shows the red  parts as the most twist part, which might let 

more sunshine into the structure. And as I move the slider to adjust the rotating 

degrees  of each curtains, the colors would present a synchronized change.
