The USGBC wanted to feature their new LEED Reference Guide for Commercial Interiors, the cover of which we had previously designed. They also wanted to communicate how one's career changes when one begins to design with environmentally sensitive materials and methods. We developed the phrase, Environmental Change From the Inside, to suggest this profound evolution, and we literally made the 20' x 20' space out of stacks of the LEED-CI Guide. All materials were 'green.'
