What is the minimum material value needed to achieve Materials and Resources Credit, Building Disclosure and Optimization, Sourcing of Raw Materials, Option 2. Leadership Extraction Practices?
A . $10,000
B . $12,500
C . $22,500
D . $25,000

Answer: D

Explanation:

According to the LEED v4 Reference Guide for Building Design and Construction, Option 2 of the Sourcing of Raw Materials credit requires using products that meet at least one of the responsible extraction criteria for at least 25%, by cost, of the total value of permanently installed building products in the project1. Therefore, for a project with a material cost of $100,000, the minimum material value needed to achieve this option is 25% of $100,000, which is $25,000.
