Posner Center & Green Roof

The Posner Center received a LEED Certification in 2005.  The structure, located next to the College of Fine Arts houses the Posner Family collection of rare books, jade, ivory carvings and executive meeting rooms.  It is said to be one of the top five private collections of of rare art and books in the world.  The new building is mostly underground with a rooftop sculpture garden.

The main entranceway, featuring one-story tall windows faces Margaret Morrison Carnegie Hall and the tennis courts.

The 11,400 square-foot building, designed by WTW Architects is a gift of Henry and Helen Posner.  Henry Posner is an emeritus life trustee of the University.

The Posner collection includes one of only four copies of the Bill of Rights printed by Thomas Jefferson in 1792 and Christopher Columbus' letter to King Ferdinand and Queen Isabella of Spain describing his first voyage to America.

With such important documents within the building, great care was taken to ensure no leaks would occur from the green roof above.  The following article describes the type of roof as well as other interesting information on the building: Sarnafil Waterproofing™ [pdf]
