PRODUCT MULTIPLIERS

Multipliers are awarded for products that earn any level of achievement in one or more criteria areas. A product does not have to be multi-attribute (meet achievement levels in multiple criteria areas) to have a multiplier. Products that achieve a first step towards sustainability for a criteria area are categorized as Level 1 and will receive a 1x multiplier. Products in Level 2 represent a leadership position in the marketplace for a given sustainability attribute and will receive a 2x multiplier. Products in Level 3 are elite and represent the forefront of sustainability and will receive a 3x multiplier. These scores are added across criteria areas to add up to a maximum score of five per product. This value is called the multi-attribute score for the product.

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 added together for a combined multi-attribute score 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 a multi-attribute score (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.

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 may earn one point for each category up to a maximum of five product categories.
