MRc6

To achieve MRc6, the LEED professional must use rapidly renewable building materials and products (made from plants that are typically harvested within a ten-year cycle or shorter) for 2.5% of the total value of all building materials and products used in the project, based on cost.

Thus, if project contractors purchase $25,000 worth of a flooring product made from rapidly-renewable materials, and the total value of project materials is $1 million, then project managers have achieved this credit.
