Lesson 7: LEED Pre-Check to Comply with LEED v4.1
LEED Pre-Check to Comply with LEED v4.1
LEED has been updated to LEED v4.1, while LEED v4 also remains in use. The LEED pre-check in the HPD Builder and Repository display is updated accordingly.
While some requirements for LEED remain the same from v4 to v4.1, LEED v4.1 introduces significant new pre-check requirements. Specifically, an analysis of the HPD content inventory, including percentage weights for ingredients and corresponding GreenScreen scores, is required to perform a complete pre-check.
Requirements for LEED v4/v4.1 Material Ingredients, Option 1 (same as current Option 1)
- Pass HPD Builder completeness check
- Basic or Nested inventory
- Indication of whether residuals and impurities were considered – any answer is valid
- Material or Product level accepted
- Characterized: “Yes” – “No” is not allowed
- Screened: “Yes” – “No” is not allowed
- Identified: any entry is valid
- Either 1,000 or 100 ppm threshold
Requirements for LEED v4 Material Ingredients, Option 2 (same as current Option 2) (new)
- Pass HPD Builder completeness check
- Basic or Nested inventory
- Indication of whether residuals and impurities were considered – any answer is valid
- Material or Product level accepted
- Characterized: “Yes” – “No” is not allowed
- Screened: “Yes” – “No” is not allowed
- Identified: any entry is valid
- 100 ppm threshold
- No GreenScreen scores of BM-1 or LT-1
LEED v4.1 Pre-check requirements
Requirements for LEED v4.1 Material Ingredients, Option 2, 100% value (same as current Option 2) (new)
- Pass HPD Builder completeness check
- Basic or Nested inventory
- Indication of whether residuals and impurities were considered – any answer is valid
- Material or Product level accepted
- Characterized: “Yes” – “No” is not allowed
- Screened: “Yes” – “No” is not allowed
- Identified: any entry is valid
- 100 ppm threshold
- Third-party verified
- No GreenScreen scores of BM-1 or LT-1, OR
- At least 75% by weight of the content inventory:
- Has a BM score, i.e., BM-1, BM-2, BM-3, BM-4, BM-U

- Identified: any entry is valid
- 100 ppm threshold
- Third-party verified
- No GreenScreen scores of BM-1 or LT-1, AND
- At least >95% by weight of the content inventory:
- Has a BM score, i.e., BM-1, BM-2, BM-3, BM-4, BM-U
- OR is entered as a Special Condition
