Parametric design

Parametric design is a design method in which features, such as building elements and engineering components, are shaped based on algorithmic processes rather than direct manipulation. In this approach, parameters and rules establish the relationship between design intent and design response. The term parametric refers to the input parameters that are fed into the algorithms. While the term now typically refers to the use of computer algorithms in design, early precedents can be found in the work of architects such as Antoni Gaudí. Gaudí used a mechanical model for architectural design (see analogical model) by attaching weights to a system of strings to determine shapes for building features like arches. Parametric modeling can be classified into two main categories: Propagation-based systems, where algorithms generate final shapes that are not predetermined based on initial parametric inputs. Constraint systems, in which final constraints are

The digital design paradox

Russell Alexander Loveridge

The fundamental methodology of design is based on the ability to imagine "what could be" - a subjective position based on the "suspension of disbeleif". The basic premise of digital tools, parametric design, and at the core logic, is fundamentally objective. How do designers negotiate the gap between these two sides of thier profession, and how is emerging technology affecting thier ability to be both objective and subjectively creative in the digital age.

Parametric Materiality

Russell Alexander Loveridge

Sustainability issues are increasingly taking more prominent positions in the hierarchy of design decisions. The combination of linked digital analysis and parametric design has emerged as an integrated method of assimilating performative characteristics into design. As these “informed design” methods evolve there is an increasing ability for architectural geometry to be rationalized, whether this is for reasons of constructive optimization, or environmental and economic justification. But the macro scale approach to geometry in design – the design of form and shape – is only one mediator of the designs impact in its surroundings. This paper will discuss what happens when designers fundamentally question the role of materials in design, and specifically what happens when “new” materials and their performative characteristics can be modelled and implemented into the digital design decision process. These approaches are showcased in “proof of concept” projects that have been developed using digital design and production technologies, in collaboration with material scientists and industry.

Parametric Architectural Design: Mass Customization Concepts and Projects in Architecture

Russell Alexander Loveridge

This paper outlines some of our recent research and built projects in the combined use of Computer Aided Architectural Design (CAAD) programming and Computer Aided Architectural Manufacturing (CAAM). The results of our work are ‘proof of concept’ built-projects demonstrating these technology driven architectural concepts. The conclusions from these projects operate on two levels: A set of conclusions with regard to the implementation of new technologies and processes for architects, and secondly, how these technologies can be presented to the different practices of architects and construction professional so as to best integrate customized Computer Numerically Controlled (CNC) manufacturing within the working methodologies and established skill sets of more traditional architects.
