What led architects to integrate digital tools into their practices? To understand the point of departure for the digital in architecture, the Canadian Centre for Architecture (CCA), through its research program, Archaeology of the Digital, collected archival records of 25 projects realized between the late 1980s and the early 2000s. If the digital is a condition made possible by the conceptual foundations of digital media (and not necessarily by digital media itself), the boundaries of the digital momentwhen it began and under what circumstancesexpands. This fascinating publication brings together 14 stories pertaining to the origins of the digital in architecture. Addressing specific changes in ways of thinking about architecture, building and cities, as well as the shifts in technology that resulted from these changes, When Is the Digital in Architecture? investigates the complex beginnings of the digital in architecture. Contributions by architects and theorists Stan Allen, Phil Bernstein, Nathalie Bredella, Mario Carpo, Wolfgang Ernst, Marco Frascari, Peter Galison, Orit Halpern, Greg Lynn, Antoine Picon, Molly Wright Steenson, Bernard Tschumi, Mark Wigley and Andrew Witt.
