Design algorithms for contemporary pattern-based building envelopes

Abstract

Pattern-based building envelope is a modern style of contemporary facades. Architects may rely on imitating known practices without knowing the processes involved in their design. Therefore, this paper seeks to identify the algorithmic steps implemented in the derivation of contemporary façade. The design algorithms of pattern-based building envelopes are classified into generative algorithms of the basic pattern and elements, and transformation algorithms. An experimentation method was applied using Grasshopper for Rhino to simulate the formation of nine contemporary pattern-based envelopes. The finding reveals that several approaches are implemented such as elements are extruded from the basic pattern or separated from it. The envelope pattern may result from repeting the elements, or the envelope pattern may be devoid of elements. Modification techniques can manipulate the basic pattern, the elements, or both patterns and elements. They act on the patterns and elements simultaneously in the same way, or separately using different ways.
