Recently the American Institute of Architects Committee on the Environment published, for the first time, a comprehensive report about the winners from the debut year (1997) through 2015: “Lessons from the Leading Edge.” Its lead author, a current COTE advisory board member, Lance Hosey, set out to review two decades of Top Ten winners as a group to see how performance is changing over time, how the winners size up (scale, cost, type), and more.

The result is a compelling report. It reveals that these high-performing projects skew small. That performance gains and metrics, particularly real-time performance metrics, are improving each year. That the leading projects tend to be expensive. On average, they come in at $537 per square foot. “The cost data shows us that we need more compelling examples of lower-cost, higher performance projects,” Hosey says. Clearly, more exemplars at greater scale, type, and cost variation would be beneficial to both the profession and the market.
