GREEN POINTS: Measures to reduce environmental impacts, such as using recycled materials, increased daylighting, low-emitting materials, innovative design and reduced water and energy consumption, earned the Kennecott Mine Administration Building and the Bingham Canyon Mine Visitor Center LEED Silver certification and LEED Certification, respectively, from the U.S. Green Building Council, Washington, D.C. The buildings’ uniqueness lies in their portability. As the mine expands and changes, the buildings can be combined with other modules to create larger or smaller buildings through reassembly. The buildings sit at an elevation of more than 6,000 feet (1825 m). In the administration building, two-thirds of the doors, frames and hardware used was salvaged from the previous mine-office building. In the visitor center, 30 percent of building materials were salvaged and reused by picking the existing building off its foundation and transporting it to the new center.
