Limit Hazardous Materials (1 point)
Projects meet one of the following requirements and develop a purchasing plan for continued procurement:
-
For all newly installed building materials, at minimum 20% by cost of the following building products and material types contain less than 100 ppm added lead:
- Doors and door hardware.
- Ductwork.
- Conduits.
- Metal studs.
- Mirrors/glass.
- Roofing or flashing.
- Brass cooler drains, pumps, motors and valves.
- Vinyl blinds or wallcovering.
-
For all newly installed furnishings and furniture (including textiles, finishes and dyes), all components that constitute at least 5%, by weight, furniture or furnishing assembly meet the following thresholds for material content:
- Mercury less than 100 ppm.
- Cadmium less than 100 ppm.
- Antimony less than 100 ppm.
- Hexavalent chromium in plated finishes less than 1000 ppm.
-
All newly installed electrical components: fire alarms, meters, sensors, thermostats and load break switches, meet the following maximum concentration value per listed substance:
- Lead (Pb): less than 1000 ppm.
- Mercury (Hg): less than 1000 ppm.
- Cadmium (Cd): less than 100 ppm.
- Hexavalent Chromium: (Cr VI) less than 1000 ppm.
Note: For the lead requirements in Part 1: Limit Hazardous Materials, other product categories can also be suggested for inclusion in the cost calculation, provided evidence/documentation for added lead content is presented.
Wherever procurement of a product or a material type is not possible, the project is permitted to submit documentation demonstrating an attempt has been made: for each listed product or material type applicable to project, a petition or formal request is filed with at minimum three manufacturers who were unable to meet their needs.
Projects can disclose or report ingredients listed here using labels approved for use in Part 1: Promote Ingredient Disclosure in Feature X14: Material Transparency to earn points toward that feature.
