In 2000, the U.S. Green Building Council developed the Leadership in Energy and Environmental Design certification system, known as LEED. Its four certification levels, Platinum, Gold, Silver and Certified, are now globally recognized symbols of sustainability achievement.
Indiana University Bloomington received three LEED Gold certifications for buildings in the past few months, bringing the campus total to nine. The School of Public and Environmental Affairs addition, Ray E. Cramer Marching Hundred Hall and Hodge Hall all received gold certification in late 2018 and early 2019, reaffirming the university's commitment to ensuring all new construction receives a minimum LEED Gold certification or higher, as laid out in the IU Bicentennial Strategic Plan.
