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” or “No” is not allowed 
  • Screened: “Yes” or “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” or “Yes Ex/SC” – “No” is not allowed 
  • Screened: “Yes” or “Yes Ex/SC” – “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” or “Yes Ex/SC” – “No” is not allowed 
  • Screened: “Yes” or “Yes Ex/SC” – “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 
  • OR is entered as a Special Condition

Requirements for LEED v4.1 Material Ingredients, Option 2, 150% 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” or “Yes Ex/SC” – “No” is not allowed 
  • Screened: “Yes” or “Yes Ex/SC” – “No” is not allowed 
  • 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
