Specification of an Operator for the Design of Architectural Forms: “Pleating”
During the creative phase, the architect introduces hypotheses and validates them by trying out various adjustments during the process of conception. The use of existing CAD tools during the conception phase is not compatible with the iterative aspect of this process. So the challenge is to define a model that takes into account the entire creative process in a trial and error framework during the conceptual phase. In this article we will define the “pleating” operator.
A Study for Parametric Morpho-Semantic Operators to Assist Architectural Conception at the Drafting Stage
In this paper, we make the assumption that a shape modelling process can rely on the application of a set of morpho-semantic operators to initial shapes. In this paper, we refer to several researches which have attempted to identify such operators. We will attempt to validate this concept through the analysis of some ''innovative" buildings. Thus, in different projects of contemporary architects, we can find the trace of some transformations (e.g. "twist", "merge", "overlay", etc.) recorded in the final geometry. These transformations have a symbolic representation. A design system based on the combination of these operators could enable the designer to quickly explore a great number of spatial solutions
Generative and Evolutionary Techniques for Building Envelope Design
The authors have been involved in the use of generative techniques for building envelope design since 1968 and the use of genetic algorithms since 1990. Recent work has focused on incorporating optimisation functions into form generating processes in order for new forms responding to varied design environments to be created and determined. This paper will summarise the authors' previous work in this field and explain the theory behind this approach, and illustrate recent developments. While the initial implementation of a new building envelope design system is reported in more details in a related paper at this conference, this paper outlines its main features and points out the direction at which it is to be fully developed and further improved.
