#6 University of North Carolina
North Carolina, USA
The University of North Carolina Chapel Hill has a strong sustainability program. Along with many buildings on campus they provide information for staff, students and the general public for attaining a greener environment.
Multiple campus buildings stand out for their green rating including the Genome Sciences Building (top), the Koury Oral Health Sciences Building and the Bell Tower Amphitheatre.
The Genome Sciences Building is 210,000 sq f and uses innovative technologies including a green roof, vertical solar fins, and active chilled beams to improve energy and water efficiency, in addition to enhancing general comfort for users. Three pod-like structures are attached to the building, framing a courtyard area.
Another leading building for sustainability on campus is the Bell Tower Amphitheater, where rainwater collected from the Genome Sciences Building roofs drains into a 350,000 gallon beneath the Bell Tower Amphitheatre Central Park area. After receiving UK treatment and chlorination the rainwater is recycled to be used to flush 1,000 toilets in both the Genome Sciences Building and the Kenan Stadium. If rainwater is insufficient, cultivated wastewater from a local water utility is implemented as a backup.

The Koury Oral Health Sciences Building replaced a previous building and completed in 2012, measuring 216,000 sq f. This building achieved a LEED Gold status with its orientation and design restoring green space in a quadrangle in addition to plenty of natural light coming into the large atrium. The design includes a pedestrian bridge that links to the University of North Carolina's School of Dentistry South Campus.
