The GRHC report, however, did point out that the green roof industry has declined 12 percent after seeing double-digit growth for the past decade.

In another nod to DC, the city also landed on the top five of the American Council for an Energy-Efficient Economy′s (ACEEE) latest rankings of the most energy-efficient cities in the nation.
The council released an online scorecard of the 51 of the largest cities in the country based on energy efficiency in local government operations, community-wide initiatives, green buildings, productive relationships with energy and water utilities and transportation.
Boston, with a score of 82 out of 100, received marks for its ordinance that requires all buildings to benchmark and report its energy usage, as well as its partnership with local utilities to connect residents with energy-saving services.
“It is an honor Boston has been recognized as America’s most energy-efficient city,” said Mayor Marty Walsh. “Our goal is to help Boston residents and businesses save energy and money, and through collaborative efforts with our utility partners, Eversource and National Grid, we are creating a thriving, healthy and innovative Boston. I look forward to continuing these efforts for both our environment and residents.”
Trailing Boston in energy efficiency are, in order: New York City, Washington, DC, San Francisco and Seattle.
“Our findings show that cities continue to be laboratories of innovation when it comes to energy efficiency, with many pushing the envelope for more energy savings in the last few years,” said ACEEE research analyst and lead report author David Ribeiro. “Cities are also improving their approaches when it comes to tracking and communicating their efforts to save energy. By capturing these efforts in the Scorecard we hope local leaders from cities of all sizes can learn best practices from each other and deliver the benefits of energy efficiency to their communities, such as a stronger economy and a cleaner environment.”
