CARRBORO -- Carrboro High School has earned top marks in environmental design, becoming North Carolina’s first Leadership in Energy and Environmental Design, or LEED, certified high school, school officials announced Thursday.

The new school is North Carolina’s second K-12 facility to earn LEED certification. The first was Third Creek Elementary School in the Iredell-Statesville Schools.

Both LEED schools were designed by Moseley Architects of Raleigh.

Among Carrboro’s features are three 35,000-gallon cisterns that collect filtered rainwater for toilets with retention ponds to catch overflow for landscape watering; classrooms, a gymnasium, media center and cafe/commons with large windows to harvest daylight; and efficient fluorescent lights to supplement rainy days and nights.
