Introduced just yesterday through a joint effort from the Department of Education and School Construction Authority, the New York City Green Schools Guide and Rating System (“GSG”) will apply to all new school construction, modernization, and renovation projects in the five boroughs. The GSG and Rating System is based on LEED, but also incorporates elements from the Collaborative for High Performing Schools Rating System (developed by Washington, Massachusetts, and New York States) and the School Construction Authority's Best Practices. It's intended to complement Local Law 86 (which mandates LEED Silver for most public projects in New York City) and, according to Schools Chancellor Joel Klein, is one of the nation's first (and certainly the largest) school districts to create and implement a green rating system for schools.
