Requirements

Specify substitutes for materials manufactured with lead and cadmium, as follow:ƒ

  • Specify and use 100% lead-free solder and flux used to connect plumbing pipe on-site for water intended for human consumption that meets the California AB1953 standard that solder must not contain more than 0.2% lead, and flux not more than a weighted average of 0.25% for wetted surfaces.
  • ƒSpecify and use pipes, pipe fittings, plumbing fittings and faucets for water intended for human consumption that meets the California AB1953 standard of a weighted average lead content of the wetted surface area of not more than 0.25% lead.
  • Specify and use lead-free roofing and flashing.
  • ƒSpecify and use electrical wire and cable with lead content
  • Specify no use of interior or exterior paints containing cadmium or lead. Green Seal certified paints or paints meeting Green Seal criteria exclude metals including cadmium, lead, mercury, antimony, and hexavalent chromium.
For copper pipe applications, reduce or eliminate joint-related sources of copper corrosion: ƒƒ
  • use mechanically crimped copper joint system, or
  • specify that all solder joints are compliant with ASTM B828 and specify and use ASTM B813 flux.
For renovation projects, ensure the removal and appropriate disposal of disconnected wires with lead stabilizers, consistent with the 2002 National Electric Code requirements. Note: To comply with the intent of this credit, specify “100% lead free” products. The “lead free” label as defined by the EPA’s Safe Drinking Water Act (SDWA) (http://www.epa.gov/safewater/sdwa/index.html) does not provide adequate screening for the purposes of this credit because these products may still contain lead. The SDWA defines “lead free” as:ƒ
  • Solders and flux containing 0.2% lead or less.
  • Pipes, pipe fittings, and well pumps containing 8% lead or less.
  • Lead used for radiation shielding and copper used for MRI shielding are exempt from the requirements of this credit.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
