DALLAS (AP) U.S. Sen. Barbara Boxer is visiting the George W. Presidential Center in Dallas to present an award for the environmentally friendly design of the building and grounds.

Former first lady Laura Bush on Monday afternoon planned to show Boxer some of the building's green design aspects.

Boxer is a Democrat from California who chairs the Environment and Public Works Committee. She's announced the establishment of the Climate Hero Award, with the first award going to the Bush center and the William J. Clinton Presidential Center in Little Rock, Ark.

Both libraries have achieved the highest certification platinum from the U.S. Green Building Council's Leadership in Energy and Environmental Design, or LEED, program.

The Bush center was dedicated in April on the campus of Southern Methodist University.
