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 "***Update 1/1/13: The original ruling is no longer valid and has been superseded by the language below. \n\nThe 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.\n\nOriginal 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."

Lamps for the lighting fixtures are purchased by a building management contractor for this campus as a whole and then distributed to each individual building. No tracking mechanism for the purchasing for each individual building is in place; however, the building is set up to track how often a lamp is being replaced and a total count of lamps for each building is available. To track reduced mercury content in lamps we are proposing that a policy be set in place for the campus as a whole to ensure that the inventory of lamps purchased meets credit requirements. In addition, while the actual number of lamps installed in a building is not tracked, we propose that the quantity of lamps is able to be tracked via disposal quantities. Each lamp that is removed from the building is recycled through a hazardous waste management program and inventoried when packaged for disposal. In addition, building changes that result in a change in the total number of lamps in the building will be documented through the respective material purchasing and waste disposal credits and the documents supporting this credit will be updated accordingly." "The project team seeks clarification regarding the use of campus-wide lamp purchasing program to achieve MR Prerequisite 1. The approach described above is adequate to achieve MR Prerequisite 1. However, to be eligible for points under the associated credit (MR Credit 4), the project team must show compliance based on a building-level picogram per lumen hour mercury values stemming from actual installed lamp types and quantities. This requires an inventory of all lamp types and quantities installed within the project building, a purchasing plan based on the inventory demonstrating that lamps models purchased through campus procurement for the project building meet the target mercury content, and evidence that lamps newly installed in the project building during the LEED performance period also meet the target mercury content (the performance period must encompass some lamp replacement activities in order to be eligible for the credit). Without assessing the number and type (e.g., 42"" T-8) of lamps installed in the project building, it is not possible to perform the calculations associated with MR Credit 4.
