Multi-attribute scoring of products Product documentation provided by manufacturers will be eligible for reward in this credit. The documentation must meet the USGBC - approved list of eligible product documentation. Individual products selected for compliance with MRc4: Building Product Selection and Procurement credit may have more than one eligible product documentation. Multiple document scores can be together for a combined MAS for that product, but only the highest value in each criteria area will be awarded. Double counting is not allowed.

Multi-attribute adjusted value Each eligible product earns an MAS based on its level of achievement in each criteria area. The MAS is multiplied by the product’s value to find each product’s adjusted product value for LEED. In a single product category, each eligible product’s adjusted value is added together and divided by the total unadjusted value of all products in the product category. This value is the product category adjusted value for LEED . This value is how to determine credit achievement. Any product category adjusted value for LEED that exceeds 100% earns one point. Any product category adjusted value for LEED that exceeds 200% earns 2 points. Points are awarded for achievement of whole product categories, up to a maximum of 10 points.

Number of product categories There are a total of nine product categories to consider, which include: paints and coatings, adhesives and sealants, flooring, walls, ceilings, insulation, furniture, composite wood, and plumbing fixtures.

Projects can earn points based on the number of categories in which they select eligible materials that meet the required criteria. Nonstructural products that do not clearly align with one of the product categories listed below may still be eligible to be included for assessment. This credit is designed to offer flexibility in evaluating different product types that fall outside the nine listed categories. This tiered point system incentivizes broader and deeper integration of sustainable materials across multiple categories, encouraging projects to enhance their overall environmental performance by incorporating products that support health, sustainability, and reduced environmental impact. Table 1 lists the product categories and some examples of products found within the categories.
