"LEED Interpretation" "1585" "2006-10-09" "Commercial Interiors" "MRc6: Rapidly Renewable Materials" "This CIR relates to the intersection of MR Credit 3.3 Resource Reuse, Furniture and Furnishings, and other MR credits - in particular, MR Credit 6, Rapidly Renewable Materials. The LEED-CI Reference Guide (Version 2.0, December 2005) contains guidelines as to how reused / salvaged / refurbished furniture and furnishings can contribute to MR Credit 5, Regional Materials. However, reused furniture and furnishings are specifically excluded from the calculations for MR Credit 4, Recycled Content. Additionally, MR Credit 7 Certified Wood applies only to ""new wood based products"", therefore the value of reused furniture with wood-based components is excluded from calculations for this credit. The Reference Guide explanation for MR Credit 6, Rapidly Renewable Materials, does not specifically address reused furniture. However, the Reference Guide explanation for MR Credit 3.3, Resource Reuse implies that the replacement values for reused furniture and furnishings are applied towards MR Credit 6, Rapidly Renewable Materials. If this is the case, MR Credit 6 does not appear to follow the logic of the other MR credits with regard to reused furniture. If it is acceptable to exclude the value of reused furniture from MR Credit 4, Recycled Content, is it not also acceptable to exclude reused furniture from MR Credit 6, Rapidly Renewable Materials?" "Yes, reused furniture that qualifies for MR Credit 3.3, Resource Reuse, 30% Furniture and Furnishings, shall be excluded from the credit calculation (numerator and denominator) for MR Credit 6, Rapidly Renewable Materials. The LEED-CI v2.0 Reference Guide (page 222) states, ""Materials qualifying as reused for MR Credit 3.1 and 3.2 cannot be applied to MR Credits 1.2, 1.3, 2.1, 2.2, 3.3, 4.1, 6 or 7."" The logic behind these exclusions is that reuse is the motivation to purchase these products. The other environmental attributes may have been motivation for the initial purchase of the products Other MR credits reward the environmental attributes that influence new product purchases.

Similar to hardwoods, bamboo forests are most sustainable when only 20 percent of the bamboo is harvested in any given year, leaving the forest canopy uncompromised and the ecosystem intact. Poorly managed bamboo forests have detrimental effects on the local economy and the environment. With demand increasing for this natural resource, FSC certification of bamboo sources ensures proper harvesting to protect the local economy and the environment. Smith & Fong\'s bamboo resource was certified by the European FSC-certifier Institut f" "The project team is seeking clarification as to whether or not bamboo can be considered a compliant material under the guidelines set forth in MRc7. The bamboo products in question have been harvested and sourced by companies that possess the necessary and current certifications from the Forest Stewardship Council (FSC). This proposal is consistent with the credit intent to, ""Encourage environmentally responsible forest management"". In addition, bamboo is often used in many of the same applications as wood products, and is considered by the FSC to be a forest product despite its technical classification as a grass. Therefore, bamboo may be included in the calculations for both MRc6 and MRc7. If bamboo is added to the MRc7 calculations, all bamboo on the project (FSC or otherwise) must be accounted for in the value for all new wood-based components for the project.

The hotel is committed to using rapidly renewable materials in the form of wool carpeting and PLA fabrics. PLA (polylactic acid) fabrics are biodegradable polyesters derived from renewable resources such as corn starch and sugarcane. The hotel is also planning to use leather on the headboards in all guestrooms and would like to determine if leather products should be included in the calculations. The LEED-NCv2.2 reference guide defines rapidly renewable materials as an \'agricultural product, both fiber and animal, that takes 10 years or less to grow or raise, and to harvest in an ongoing fashion\'. Can the leather be considered a rapidly renewable material? How does the USGBC determine which animal agricultural products are included? Are there established standards or restrictions that must be met by the industry (i.e. humane treatment, use of by-products of other industries, etc.)?" "The project team is seeking clarification on the use of leather as a compliant material under the guidelines set forth in MR credit 6 regarding rapidly renewable materials. On page 411 of the LEED NC v2.2 reference guide ""rapidly renewable materials"" are defined as material considered to be an agricultural product, both fiber and animal, that takes 10 years or less to grow or raise, and to harvest in an ongoing and sustainable fashion. Although leather is an animal product, it is not deemed to be rapidly renewable as the leather material or hide may not be collected until after the death of the animal. An example an acceptable renewable animal source would be sheep\'s fleece. The fleece can be sheered from the animal without presenting harm to it nor does it prevent the animal from regenerating the material. Applicable Internationally. " "None" "None" "X"
