The San Luis National Wildlife Refuge in San Luis, Calif., encompasses more than 26,800 acres of wetlands, riparian forests, native grasslands and vernal pools. It has three automobile tour routes with associated nature trails and observation platforms from which visitors can view and photograph wildlife and nature.

The 16,500-square-foot refuge complex features an inverted roof design to symbolize the wings of a bird in flight. Installed by Top Built Inc., Rancho Cordova, Calif., AEP Span's 24-gauge, 17-inch-wide Design Span® hp standing-seam metal panels in bare Zincalume® Plus were chosen for their ability to complement the refuge's surrounding environment and provide a reliable platform for roof-mounted photovoltaic arrays.

The metal roof system contributed to the refuge earning the distinction of the highest-performing facility in the Fish and Wildlife Service. The facility has been designated a net-zero energy building and earned LEED® Platinum certification.
