I. Review

Q. How can we generate points (0,0), (10,0), (20,0), (30,0), (40,0), (50,0)?
A.Use a Series that starts with zero, steps 10 and has a count of 6

Q. How can we generate petals of a flower that are interactive (number and

angle?)
A. Use the Rotate command and feed in a list of angle numbers: i.e. Start = 0, Step = 90 and Count = 4

Q. How can we identify a specific petal to adjust?
A. List Item will isolate the Nth of a group.

II. Remap numbers

III. HELIOTROPE  http://www.food4rhino.com/project/heliotropegh?ufh

A) Set the time with Rhino: Sun command
Outputs sun vector, numbers for altitude and azimuth
Remap number to move solar module.

B) Solar Arc: Set the Julian Day manually, Adjust sunrise to sunset % to override hour.

C) My Shadow

Class Notes
April 21, 2015

I. Form-Finding: Frei Otto’s Institute of Lightweight Structures, Stuttgart
Digital/Material explorations : AA, Stuttgart, CITA, RMIT

II. Form-Finding: meshes with Kangaroo
In-class:  Create a simple structure in Kangaroo

Revised Assignment 3

Use biomimetic principles to design a module for a wall system that will modulate light as well as collect or direct rainwater.  Then create a GH definition that shows how the module could be adapted for different conditions: either as custom located alternative versions or as a kinetic piece.  Keeping in mind the collective effort to create an installation.
Assume the Willamette Valley situation with dry hot summers and wet cool winters.

For next Wed April 29, each student should address Steps 1 & 2 of the following process, and work with classmates to find a direction.
1. Material: using a biological example or an architectural example based on biomimicry as inspiration, experiment with materials for a structural module
2. Digital:  model an adaptable or dynamic module in GH, cluster and refine
—
3. Material: Build several revised module prototypess and experiment with module clusters
4. Sketch potential overall forms, plan installation.
5. Submit scheme for installation approaval
—
6. Digital: Model overall form in Rhino GH
7. Digital: Simulate performance with daylighting simulation and rainwater catchment
—
8. Gather materials and build

Readings

Please read these two articles that are on the course folder under Readings

• Natural structures: strategies for geometric and morphological optimization  by Agustín PÉREZ GARCÍA & Fernando GÓMEZ MARTÍNEZ provides a strong rationale for biomimetic structures using beautiful examples.
• Evolutionary Architecture, some perspectives from biological design by J.Scott Turner, from Architectural Design magazine.

MIT Professor Neri Oxman’s video and the Materialecology blog , explains how she uses biology as inspiration. She explains how she designed not objects but new processes for sculpting form from the interface of environment and materials, using computational analysis and fabrication. She likens the designer as a gardener steering towards environmental fitness.

Let me know if you have any questions.

Case Study Assignment 2

due Wednesday 4/22

The purpose is to help you see how architects have successfully used biomimicry in their design process. Ideally you will locate someone who has approached a design problem similar to one that you are addressing. Focus on one to three projects by that person.

How does the designer use forms, processes or systems from nature to advance design ideas? (Does this match the Biomimicry 3.8 model?) When is what tool used and for what purpose? What steps are followed in the process from concept to building?

How does the person
 describe the problem
 analyze relevant site, program and precedent information
 generate concepts
 create and evaluate variations (aesthetics, performance criteria?)
 consider constructability & refine material assemblages
 present the project to clients and builders

Create a 10 minute illustrated presentation and upload it as a PDF to the course folder.
