Emergence is the process by which new and sound structures, patterns and properties emerge from within complex systems. Emergence, also referred to as evolutionary optimisation, is an essential new concept that has been applied to information theory, artificial intelligence, digital technology, climate studies, economics, material science and biometric engineering in recent years (Hight, Hensel and Menges). In an architectural context it entails harnessing evolutionary processes for the design of buildings as well as structural design and the composition of new materials (Hensel, Menges and Weinstock). Thus, architecture is seeking to achieve a new level of complexity as it aspires to match the restive perfection of systems in the natural world. Emergent design is the process of evolving systems in response to changing requirements, better understanding of existing requirements, and in response to new opportunities that arise from better ideas, new technology, and a changing world.
