ARC 6760 - Advanced CAAD
Adaptive Skins Using Generative Systems
MAAD 2012-13
Aim To explore and design adaptive skin prototype definition using generative systems.
Parameters Solar Irradiation Shadow Mapping Construction Material
Advantages Controlled natural daylight Controlled solar heat gain and glare Reduced Energy requirement
Experiment Structure Phase -1 1. Conceptual Design (in Rhino) 2. Development of Parametric definition (in Grasshopper with Diva) Phase - 2 1. Flexing the system and analyzing performance (using Diva with Rhino) 2. Generating Simulations (Diva with Rhino) 3. Exploring fabrication options (materials and kinetic skin examples)
Conceptual Geometries –
Constructed Using logic based modelling techniques in Rhino & Grasshopper
Three Combinations of a module used to generate the adaptive skin

Creating digital morphogenesis using grasshopper algorithms based on set of rules that respond to the spatial quality & sustainable aspects of a given geometry. - Morphing done using generative systems in grasshopper.
Manipulating results by testing a range of inputs or "fl exing" the system we've created and gathering data for further analysis from tools such as Autodesk Ecotect. Input parameters – Sun Positions Daylight Location Materials used
Difference in need of the openings can be observed depending on the type of material used.

The process of flexing the model allows us to determine the range of inputs and outputs that are possible for a given system.
In the final step systems are rationalized, output files for manufacturing to create physical models and simulations. This leaves the skin with the visual and performance characteristics intended but simplifies the system. - Extract Geometry & Planarize Curved surfaces
Adding thickness to the skin for fabrication in Z350 Printer. Offsetting the surface in rhino before export to .STL
