1.7 Layered Membranes and arrayed Minimal Holes 01

Kazutaka Fujii – Microecologies @ LMU, 2006

 

The research focused on the possibility to span continuous membranes between layers of metal grid that serve as a frame, while introducing cuts and minimal holes as an array of features that articulates the membrane geometry and therefore its performance on a local scale. Thus, while the frame is entirely generic the membrane layers spanned between the layers of metal grid begin to acquire a high degree of differentiation through the location and size of minimal hole and varying distance between the membrane layers. Two performance criteria informed the elaboration of the system: airflow and sunlight. The latter concerned the way in which light and shadow pattern are distributed on the various layers of the membranes and the space and surfaces beyond the assembly. The orientation of the membrane assembly to the sun path and the prevailing wind direction is therefore crucial. Extensive physical tests and the construction of full-scale prototypes were conducted to map the shadow pattern and airflow conditions relative to the degree of exposure, rotating the assembly relative to the direction of the environmental input and mapping the resulting conditions. This made it possible to relate the distribution of the bearing points of the membrane and the direction of tension force applied to the membrane and the minimal holes to the specifically resultant conditions with regards to airflow, light and [self-]shading pattern. Through simple modifications of the material system it was possible to achieve and regulate an extremely fine grading of effects.
