More than 30% of firm leaders report that the share of their projects designed to meet a sustainability rating system will increase over the next two years. Another 51% report that their share of such work will stay steady, and only a small percentage expect decreases. Most of those reporting decreases are sole practitioners and small firms. The largest reported growth in sustainability-related design is at midsized firms and in education and health care projects. Overall, the share of design work dedicated to these sustainability rating systems (e.g., LEED, WELL) is highest at the largest firms and those located in the West.
