One point and up to a maximum of four will be awarded for each 10% of the total value of all building materials and products used in the project (based on cost) that meet the criteria below. If concrete or steel structural elements are applied toward this credit, the project must include at least two other materials or products from CSI Master Format Divisions (other than 03 and 05) to attain the first point. Of the total recycled content, no more than 75% may be steel or concrete. 1. The cost of any individual material or product may be added for each of the following sustainability criteria that the material or product meets:
OR
OR
OR
OR
AND
2. Wall, ceiling and flooring systems and finishes, composite wood, agrifiber and fiberglass products, both exterior and interior adhesives, sealants, coatings, roofing, and waterproofing products must meet the relevant IEQ Credit 4: Low-Emitting Materials requirements to contribute toward the credit.AND
Mechanical, electrical and plumbing components and specialty items, such as elevators, shall not be included in this calculation. Only include materials permanently installed in the project. Furniture is not included (see Credit 5.1-5.3).AND
Recycled content shall be defined in accordance with the International Organization of Standards Document ISO 14021-1999—Environmental labels and declarations—Self-declared environmental claims (Type II environmental labeling).AND
Supplemental cementitious materials derived from coal fired power plant wastes shall not have mercury content >5.5ppb (0.0055 mg/L). Fly ash generated as a by-product of municipal solid waste incinerators does not qualify as a recycled-content material for this credit.What does it cost?
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.

Note the following addenda under \'Calculating Materials Costs to Achieve MR Credits\' on page 337:Add the following after "...Furniture and Furnishings as long as this is done consistently across all MR credits.", "Exclude artwork, interior plants, and musical instruments."

After the third bullet, add: "OR Building materials or products shipped by rail or water have been extracted, harvested or recovered, as well as manufactured within a 500 mile (800 kilometer) total travel distance of the project site using a weighted average determined through the following formula: (Distance by rail/3) + (Distance by inland waterway/2) + (Distance by sea/15) + (Distance by all other means) = 500 miles [800 kilometers]"

Revise the Total Sustainably Sourced Furniture & Medical Furnishings value from $70,500 to $74,250. All other calculations are correct.
The proposed project site is located on a military base that has potentially unexploded ordnance on-site.Protection from potential detonation during construction is required by the federal government to shield pedestrians and existing housing across the street from the project site. As a part of the project, a detonation barrier is to be constructed prior to start of excavation. This barrier can be built using various material but must have substantial foundations and structural strength to withstand large explosion forces. After construction is completed, the detonation barriers would be deconstructed to allow access to the site.The project team is proposing to incorporate salvaged local material into the design of these barrier walls. May the salvaged material qualify for MR credit 5 for regional material, MR credit 4 for recycled content?
The project team has inquired whether materials used for a temporary (during construction) detonation barrier can be included within the project material cost accounting since it is mandated to be built, particularly as it relates to recycled content, local material content, and construction waste management. No, the LEED Reference Guide for Green Building and Construction 2009 Edition Materials and Resources credits 3, 4, 5,and 6 "Include only materials permanently installed in the project" temporarily installed materials are considered equipment and cannot be included in MR Credits 3-6.
Please provide clarification on documentation of recycled content claims and FSC certified claims for woods products such as particleboard, MDF and other composites.
The project team in inquiring how to document products with valid recycled content claims as well as FSC certification. Products identified as FSC Mix Credit or FSC Mix [NN] % also have pre- or post-consumer recycled content, the latter of which is commonly reported separately by the product manufacturer. In these instances the project team must choose whether to classify the product (or some fraction of the assembly) as FSC certified or as recycled content; the material cannot contribute to both claims simultaneously. Specifically claims may be made under either MRc4: Recycled Content, or MRc7: Certified Wood. Note that for recycled content claims the material must meet the definition of ISO 14021 as required by LEED.

We are performing a comparative analysis for fiberglass insulation regarding MR Credit 4: Recycled Content. Depending on the manufacturer, recycled content is reported either a plant- and product-specific average, or a country-wide average (various plants and products). We have contacted a manufacturer using North American average recycled content claims, and they state that the recycled content across their facilities and product lines can range from 0-70%. Are country-wide recycled content averages acceptable as documentation for MR Credit 4: Recycled Content? If country-wide averages are not acceptable, what level of specificity is acceptable?
***Update 1/1/13: The original ruling is no longer valid and has been superseded by the language below. The project team is requesting clarification regarding the documentation of recycled content for Materials and Resources Credit 4: Recycled Content. Recycled content claims must be specific to the installed product. The installed product refers to a unique product distinguished by color, type, and/or location of manufacture as identified to the consumer by SKU or other means. It is acceptable to use an average recycled content value stated by a single manufacturer for a single product. Recycled content claims for custom products are required to be product specific; industry wide or national averages are not acceptable for the purposes of LEED documentation. Note, for the purposes of LEED, steel has a previously established industry average of 25% post-consumer recycled content which does not require documentation on a per product basis. In all cases, if recycled content is given as a range then the lowest recycled-content percentage will be used for LEED documentation. Applicable Internationally.Original Ruling: The project team is inquiring about the acceptability of using a country wide average value for recycled content of a product. An average recycled-content claim, especially one that incorporates multiple product lines or places of manufacture, does not meet the credit intent and is not acceptable for LEED documentation. The product that is known to have zero recycled-content may be unduly benefiting from the recycled-content of other products/manufacturing facilities. Recycled-content claims must be specific to the installed product (and therefore place of manufacture), regional or national claims do not meet credit requirements. If product-specific recycled content is given as a range, then the lowest possible actual recycled-content number must be declared for LEED documentation. GBCI recognizes that this presents a challenge to design and construction teams as it is often not possible to specify or even identify-- the location of manufacture for a number of materials. It is hoped that manufacturers will respond to market demand for useful, credible product information. Note that this ruling does not apply to steel products, which have an established average recycled content of 25% and do not require documentation on a per product basis when that value is used in the LEED calculator. Applicable Internationally.
