Parametric design systems serve as powerful assistive tools in the design process by providing a flexible approach for the generation of a vast number of design alternatives.

However, contemporary parametric design systems focus primarily on low-level engineering and structural forms, without an explicit means to also take into account high-level, cognitively motivated people-centred design goals.

We present a precedent-based parametric design method that integrates people-centred design “precedents” rooted in empirical evidence directly within state of the art parametric design systems.

As a use-case, we illustrate the general method in the context of an empirical study focussing on the multimodal analysis of wayfinding behaviour in two large-scale healthcare environments.

embedded design precedents lead to the (parametric) generation of a number of morphologies that satisfy people-centred design criteria (in this case, pertaining to wayfinding).

Our research presents an exemplar for the integration of cognitively motivated design goals with parametric “design space” exploration methods.

We posit that this opens-up a range of technological challenges for the engineering and development of next-generation computer aided architecture design systems.

Parametric design is a well-established method in several engineering and manufacturing design domains such as architecture, product design, and construction.

Decoupling form from physical structure, parametric and generative approaches offer the ability to rigorously explore many design alternatives and reveal new solutions during the design process.

They have been used to replace traditional shapes with more eccentric morphologies and provide adaptability and flexibility in the design procedure.

The Trade Fair ceiling project is an example of optimisation of the construction, while the Al Bahr Towers project dynamically incorporates environmental attributes into the design procedure.
