Assignment SMT03: Biomimicry
1. find a bio-system (plant, species, etc.) on asknature.org that deals in
whatever function, process or structure with the environment DESERT.
Please each student one topic and a different one. >
2. analyze how it works:
in a minimum of 3 diagrams showing
>shape, form, design, structure
>mechanism, function, materials
>process of how it works
3. establish a concept of what you as urbanist/architect would like to
do with it.
4. apply your findings to concepts for systems applied in urbanism and/
or architecture.Weighting: 20% single work
Submission: Wednesday 06.03.2012 @ 11am
stick printed sheets onto a wall in your studio. arrange neatly.
thank you
