Flux Redux is a book about design experiments undertaken at the Zurich and Los Angeles-based firm agps Architecture over the course of three decades. The story it tells addresses the evolution of a body of work relative to the evolution of environmental discourse, reflecting also on the shifting relations between technology and sustainability in architecture. The nine case studies from agps Architecture's portfolio record changes in how architecture is thought about and how it is made. Around 500 illustrations in the book are supplemented with texts by Marc Angelil, one of the founders of agps, and Cary Siress, architect and professor at the Nanjing University's Graduate School of Architecture and Urban Planning. Further contributions are provided by Swiss structural engineer Ernst Hofmann and Margarete von Lupin, a Zurich-based scholar of design and media studies and lecturer at Zurich University of the Arts and University of Zurich. Additional texts by Rainer Hehl, architect and visiting professor at Technische Universitat Berlin and Yokohama National University, and Alvaro Siza, one of the most distinguished architects of our time, round out this inspiring volume that also offers observations on architects' never-ending task of trial and error to make each building a more sustainable agent of a larger environmental system.
