But it's not a redwood building, and the roof is not merely decorative; it contains a complex conservation system. As to the building's siding that looks like wood - it's concrete, stamped and colored. In addition to providing good insulation, it's made of recycled material as well.

Coal Combustion Products: Trash or Treasure?

(Power Engineering 4-06) One man’s trash is another man’s treasure. Although the by-products created during the coal combustion process are not exactly trash, coal-fired power plant owners must find either a viable use for them or a place for their disposal. In many cases, these by products can be used by other industries, making them at least a valuable resource.
