The collective book “Les 101 mots de l'adaptation” (The 101 Words of Adaptation), edited by Atelier Franck Boutté, has just been published, and we had the honor of writing one of its 101 entries! Our three co-founders, Tim Cousin, Olivier Faber, and Eytan Levi, focused on the issue of building envelopes and their architectural potential in adapting to climate change. “Thus, [...] all the spaces between the envelope become places to be re-examined and re-invented, in order to realign our buildings—and at the same time, our lifestyles—to a new climate context.” Many thanks to Franck Boutté, Alix Derouin, and Elise Lenoble for bringing together a mosaic of actors we admire in this book and for inviting us to be part of it, to Camille Chalot and ARCHISTORM for publishing this book, and to all the partners who made its publication possible.
