(Required)
INTENT
Reduce or eliminate human exposure to building materials known to be hazardous.
SUMMARY
This WELL feature requires the restriction of hazardous ingredient components in newly installed building materials, specifically through the restriction of asbestos, mercury-containing lamps and lead in plumbing products and paint.
SOLUTIONS
IMPACT
Restriction of known hazardous ingredients found in building materials, specifically in those that are newly installed, aims to reduce risk of exposure, whether directly within the indoor environment or through environmental contamination. This also helps to push for reformulations of key building materials and products and promotes innovation in green chemistry.
REQUIREMENTS
Restrict Asbestos
The following newly installed building materials contain asbestos less than 1% by weight:
-
Thermal system insulation (applied to pipes, fittings, boilers, breeching, tanks, ducts or other like components to prevent heat loss or gain).
-
Surfacing material (that is sprayed, troweled or otherwise applied to surfaces, for example acoustical plaster or fireproofing materials).
-
Wallboard/millboard, resilient floor covering, roofing and siding shingles (including metal cladding) and construction mastics.
Note: 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.
Limit Mercury
All newly installed products meet the following:
-
Illuminated exit signs, thermostats, switches and electrical relays are mercury-free.
-
Low-mercury or mercury-free lamp technology meets the following specifications:

Restrict LeaD
All newly installed building materials meet the following materials composition requirements:
-
Drinking water systems and plumbing products are lead-free as defined by the Safe Drinking Water Act (SDWA) and certified by an ANSI Accredited third-party certification body.
-
Indoor paints and surface coatings contain less than 90 ppm total lead.
Note: 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.
ADDITIONAL POINT OPPORTUNITY
To earn an additional point for WELL Core and MFR Certification, projects should require compliance in leased spaces.
