A study in green science

摘要

St. Olaf College in Northfield, Minn., is one of the few educational institutions to receive a U.S. Green Building Council LEED Platinum rating for one of its buildings. The college's Regents Hall of Natural and Mathematical Sciences opened in September 2008 and is expected to reduce energy costs by 50% compared to the Minnesota Energy Code, which is based on ASHRAE 90.1-2004.
