Kroon Hall was Yale's second LEED Platinum Certified Building

Yale’s 300 year-old campus is home to a quickly growing collection of innovative green buildings and laboratories. Since the completion of the Class of 1954 Chemistry Research Building,  Yale’s first LEED-certified structure, the University has mandated that all comprehensive new construction and renovation project designs must meet LEED “Gold” status or higher.
