PARAMETRIC FACADE - ASSIGNMENT 1

DECODING PARAMETRIC FACADE :

This exercise is to experiment with Rhino and Grasshopper to decode the parametric logic behind any building’s facade.

AQUA TOWER

Architects – Jeanne Gang
Location – 200 North Columbus Drive, Chicago, IL 60601, United States
Project Year – 2009

STEPS TO EXPLAIN GRASSHOPPER DEFINITION :
• Create a Surface in Grasshopper of 205 m by 40 m which is equivalent to 82 stories required for Aqua Tower.

• Join contour with surface on a distance of 2.5 (per floor height) m, then project the contour in X-Z plane to the value of 1.

• Using ruled surface, rule the projected contour and Extrude them in Unit Z to the factor of 0.3, this is create a solid contour ruled surface.

• Now using pull points pull the points to the designated curves required for Aqua Tower.

• Make a rectangle behind this surface of the 40 m by 30 m and explode the rectangle and join it with list item.

• Now extrude the rectangle in Unit Z by 205 m, then Iso-trim it and Extrude it in Unit Y to the value of 30 to make each floor visible .

• Now use Divide Domain to divide the façade in 82 floors and 10 windows , further simplify the domain.

• Use flatten tree to simplify the information provided by tree in different branches to one simple branch.
• Surface from points is used for making surface and then is converted to Mesh.

• Now use Weaverbird picture frame to make a mesh frame and Weaverbird mesh window to make windows inside the mesh frame, further color the mesh using mesh color.
• Coincide both the pull point surface and the Mesh to complete the façade.
