The summer school investigates how concepts of interactivity and responsiveness can suggest new ways of thinking the relationship between the building and its environment. The contemporary societal context necessitates the thinking of sustainable solutions for our built environment. But how do these challenge the way we think and design space? How do we challenge our understanding of sustainability from being a set of posterior technological implementations to become part of the intellectual thinking and culture of architecture? Where formalist design traditions uphold the autonomy of the architectural artefact, we ask how ideas of interfacing and actuated behaviour can allow a re-conceptualisation of core architectural terms such as context, shelter, programme and extension.
