GREEN ARCHITECTURE
Portland, Oregon
Although Chicago has the most LEED-accredited buildings in the U.S., Portland, Oregon, whose population is a quarter of the size, has the sixth highest number, making it the city with the highest concentration of green buildings. In addition, zoning regulations that preserve urban agricultural spaces, a bike-friendly layout, and energy-efficient homes whose designs take on organic shapes and materials make Portland—along with the design firms it is home to—a leader in sustainable architecture.
