Wayne N. Aspinall Federal Building and U.S. Courthouse: Grand Junction, CO
Historic preservation and net zero energy performance may seem like opposing goals. But the modernization of the nearly 100-year-old Aspinall Federal Building and U.S. Courthouse demonstrates that it is possible to restore the former glory of a building's historic features and cut energy use in half. The building is approaching net zero energy and is expected to achieve that goal after controls adjustments and other measures.
