2006 – Minneapolis Central Library

The new Central Library building, designed by Cesar Pelli, along with the Minneapolis architectural firm Architectural Alliance, opened to the public on May 20, 2006. At a cost of $250 per square foot, the library features a host of energy-efficient measures, including a roof garden and substantial daylight. An 18,560 square foot green roof covers the north half of the building. This is the first large-scale utilization of green roof technology in Minnesota.
