There are three achievement levels for products:

• Level 1 : A product in this level achieves a first step toward sustainability for a criteria area. Widespread achievement of these practices drives market transformation toward sustainability outcomes within the criteria area. Products scored at this level earn a 1x multiplier.

• Level 2 : This level represents a leadership position in the marketplace for a given sustainability attribute. Products at this level are optimized and demonstrate a level of sustainability that peers aspire to achieve. Products scored at this level earn a 2x multiplier.

• Level 3 : Products that earn this level are elite and represent the forefront of sustainability. Products scored at this level earn a 3x multiplier.

This credit rewards the selection of eligible interior and enclosure materials from the following product categories:

• Paints and coatings

• Adhesives and sealants

• Flooring

• Walls

• Ceilings

• Insulation

• Furniture

• Composite wood

• Plumbing fixtures

Eligible products meet the achievement levels and are scored as 1, 2, or 3. These scores are added across criteria areas to add up to a maximum score of 5 per product. This cumulative score is called the product multi-attribute score (MAS).

Each individual product’s value (cost, area, volume, or unit) is adjusted based on its MAS:

Product value × MAS = Adjusted product value for LEED To determine total compliant product value per category, follow Equation 1.
