Appearing almost alive, computational design models become the place of investigation and creation for architects in the design process. The ability to loop, sense and query and the integration of near real-time simulation provide these models with a depth and agility that allows for instant and informed feedback. However concepts for the implementation of feedback in a computational design cycles are only emerging. Introducing the term “Aware models”, this PhD has a focus on material behavior and takes its point of departure within the practice of CITA. It investigates how a novel kind of materially informed computational models can become an exemplar for a practice, which develops architectural design in a continuous feedback loop with multiple computational sources.
