Implementation in the Design Process:
For M.4A, M.4C and M.4D:
In Predesign and early design, determine likely product categories that will contribute to compliance with this requirement. Early product research should be conducted to evaluate opportunities specific to project needs. This may be done by searching for approved products in databases or by contacting product reps and manufacturers. GreenScreen certification marks compliant with LEED v.4 are acceptable as documentation for B3 compliance. Health Product Declarations (HPDs) may also demonstrate GreenScreen results.
Through the design process refine contributing product list and look for opportunities to add contributing products as the design changes. A product may contribute toward M.4A, M.4C or M.4D if that product has been evaluated as defined in GreenScreen v1.2 Benchmark, has received a Cradle to Cradle (C2C) v2 Gold or Platinum or Cradle to Cradle v3 Silver, Gold or Platinum certification, or are certified as meeting Declare Label Declaration Status of LBC Red List Free.
Under GreenScreen products that have fully inventoried chemical ingredients to 100 ppm that have no LT-1, LT-P1 or BM-1 (Benchmark 1) hazards are:
- Any materials that have all its ingredients assessed with the GreenScreen List Translator and have been found to be free of LT-1 chemicals.
- Any materials for which all ingredients have undergone a full GreenScreen Assessment and have been found to be free of BM-1 chemicals.
- Any materials referenced in the Pharos or Portico databases and vetted for use in B3 Guidelines documenting either no LT-1 or no BM-1 chemicals.
As in early design, evaluate opportunities for reduction in fluorescent fixtures to reduce the need for low-mercury bulbs. In construction documents specify any fluorescent lamps that fall under this guideline meet the limits specified above.
