Custom expanded materials respond to environmental inputs through
directional deformation. Expanding meshes increase the overall
coverage of a sheet, while producing a perforated product without
slugs, waste products from punch holes. Rather than uniform
distribution expanded sheets, CNC technology allows for customization
expanded products to respond specifically to its locale.
Digital simulation allow designers to visualize and test the form
according to a wide range of design criteria. Parametric modeling
software is implemented to pre-expand mesh geometries and accurately
define the outcome in a computer model. Using GenerativeComponents
software, genetic apertures are modeled based in length, shape, and
spacing of the aperture incision, formed from Rhino scripting methods.
Across a building surface, the expanded skin panels respond digitally
to performative inputs like solar-gain, wind-channeling, or
rain-screening by adjusting the aperture length and proportioning
relative to global orientation. The directional qualities exhibited by
meshes act as small hoods covering the surface of a roof or wall
system. These modifications are built into the parametric design
geometry and the apertures update automatically as the parent geometry
is altered.
