Today's facade designers cannot afford to ignore the question of sustainability, and in particular energy efficiency. James O'Callaghan (Eckersley O'Callaghan), William Logan (Israel Berger & Associates), and Will Laufs (LaufsED) sat down with our partners at Enclos during April's facades+ NYC conference to talk about the push and pull between aesthetics and environmental performance in building envelopes. Top AEC professionals will continue the conversation at facades+ Chicago on July 24–25. For more information or to register, visit the conference website. Early Bird registration ends June 29.
