One of the more exciting realities of 21st-century life is that objects are now able - with the help of embedded technology - to sense, think, act and communicate. Very soon, every building, city and landscape component will be equipped with communicative and computational capacities: we shall be surrounded by sentient architecture. This book documents the role of architecture in shaping this new reality in multiple research trajectories launched and guided by the authors at The University of Toronto, MIT, Harvard Graduate School of Design and the University of Hong Kong. The projects establish an interdisciplinary platform involving artists, designers, scientists and engineers spanning different institutions and continents in a technological approach to spatial problems that is attuned to the dynamics of living systems. The collective aim is to develop from the collaborative experiments a digitally enhanced architecture that is well-equipped to handle persistent and emerging challenges in building a healthy and sustainable environment.
