Abstract

A practical implementation of cellular automata (CA) in the field of architecture is presented, where a CA drives a modular shading system of a building facade. Application of a 2-color, 1- dimension, range- 2 (2C-1D-R2) CA on a square grid for a regular type of a building facade and the prototype of a CA controlled shading device is presented. The problem of average grayness of a pattern is presented. The solutions for problems of linear gradual change of average grayness as a function of sequence of initial conditions and the sequence of initial conditions which cause desired opacity change of the shading array are presented. The fabrication of the CA shading prototype consists of: design of the logic circuits, fabrication of the units, followed by design of the LCD panel and the acrylic casings.
