DES MOINES, Iowa (AP) — A century-old former public library renovated to become the home of the World Food Prize Foundation has been awarded the top energy efficiency and environmental design rating.

The World Food Prize Hall of Laureates in Des Moines, which is on the National Register of Historic Places, has been awarded a LEED Platinum rating from the U.S. Green Building Council. The Washington-based nonprofit organization promotes energy-saving building construction. Only a handful of 19th century buildings in the United States have the platinum rating.

Renovation of the building, which first opened as the Des Moines Public Library in 1903, cost $30 million.

It includes high efficiency solar panels, a geothermal system to heat and cool the building, and an 8,000-gallon storm water collection and storage system used to water the gardens.
