For a project to earn one point for Materials and Resources Credit, Environmentally Preferable Products, what must occur?

To earn points under the LEED v4 for Homes Materials and Resources (MR) credit for Environmentally Preferable Products, a project team can choose Option 2. This option requires the project to incorporate a specified number of products that meet various environmental criteria, such as being salvaged, having recycled content, or being bio-based. Points are awarded on a tiered scale based on how many of these criteria (or attributes) are met across the project. Option B correctly describes this mechanism of meeting multiple criteria to earn credit, which is the fundamental structure of this compliance path. While exactly one point requires meeting four attributes, this option is the only one that accurately reflects the credit's methodology.

A. This is incorrect. The credit does not use a 95% by weight or volume threshold; points are awarded based on the number of qualifying product attributes achieved.

C. This is incorrect. Option 1, Local Production, awards points based on the number of qualifying locally sourced products, not a 95% threshold of a single component.

D. This is incorrect. Option 1 and Option 2 are alternative pathways to earn points within the credit. A project team can pursue either option independently and is not required to meet both.

Reference Details: MR Credit: Environmentally Preferable Products, page 91. The credit details for Option 2, "Environmentally Preferable Products," show a table where points are awarded based on the number of attributes met (e.g., 2 attributes for 0.5 points, 4 attributes for 1 point). This confirms the mechanism described in option B and refutes the thresholds in A and C, and the combined requirement in D.
