81st Street Green Roof
Calhoun’s Green Roof Learning Center was the first eco-friendly green roof in NYC dedicated to educational study. Opened in 2005 as part of a four-story addition to the school's main building at 81st Street, the Green Roof is used as part of classroom lessons, a source of fresh produce, and a space for community events.
