Green Squared is the ANSI A138.1 sustainability mark for tile
A Tile Council release dated 26 August 2016 says ceramic tile, glass tile, and tile installation materials can contribute to a LEED pilot credit only when they meet Green Squared, which the release identifies as ANSI A138.1, the multi-attribute sustainability standard for those products. Third-party certification is required before a product may carry the mark.
The credit's threshold
The pilot credit named in the release is Certified Multi-attribute Products and Materials. At least 25 percent, by cost, of the permanently installed building products must meet a U.S. Green Building Council-approved sustainability standard and have third-party validation. For this mark the release names UL Environment, NSF International, and SCS Global as the certifiers.
The contribution is not automatic
The release says how much a certified product contributes depends on recycled content, closed-loop manufacturing waste, and regional raw materials. Certification details, including which electives were met, have to be disclosed, and a lifecycle assessment has to have been done.
