Footprint 28' examines the relation between cybernetics and architecture by focusing on a problem they both share: the production, consumption and flow of information, or, in other terms, of meaning. Therefore, cyberneticisation can set the foundations for a relational account that examines how signs are communicated and how meaning is produced and experienced within systems. This third-order cybernetics extends beyond the original scope of living organisms and their environments in order to include ecologies of ideas, power, institutions, media and so on. In this sense, cyberneticisation is radically environmental, positing the primacy of relations over fixed terms, binary oppositions and linear logics, making it high time for architectural and urban studies to take into consideration its ground-breaking potentials.00While there have been significant discussions on the relevance of cybernetics within architectural and urban studies, focus was mainly placed on computing and digital practices. The influence of cybernetics towards formulating an alternative ecological ? i.e. relational ? account has been mostly neglected. However, the Anthropocene, both as a discourse and a material condition, has brought to light the need to rethink environmental histories and environmentalism in architecture beyond reductive binary logics. The once separate categories of culture and environment now give way to an ecological approach where they appear as co-constructed, providing a broader transdisciplinary circuit to explore the logics of living systems in ways that are not restricted to anthropocentrism.
