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.

Science centers are not by design energy-efficient, due mostly to their high air-exchange requirements. The Regents Hall features an HVAC system designed with an extended-size 53,000 cfm Vision air handling system from McQuay. The system is designed not only for high air exchange, but also for low energy consumption, which helped the college earn LEED points and meet budget requirements.

The $64 million building is a model for interdisciplinary science education. New lessons on green living and sustainability include how the green roof impacts a waterfall collection system to reduce the cooling load. Regents Hall is also the first major science facility in the country designed for “green chemistry,” which minimizes the hazardous chemical waste from lab experiments. The labs use one half the number of fume hoods compared to the same curriculum with conventional chemistry.
