Sustainable Stone certification now recognized in both leed v4 and LBC
HOLLIS, NH -- The Natural Stone Council (NSC), an association comprised of the leading natural stone associations throughout the country, has announced that its Sustainable Production for Natural Dimension Stone (ANSI/NSC 373) certification is now recognized by the U.S. Green Building council’s LEED v4 building certification program, as well as the International Living Future Initiative’s Living Building Challenge (LBC) version 3.1. Now, design teams have a clear path to ensure the stone they specify helps projects reach sustainability goals as outlined by LEED and LBC.
“Being named an approved program by the USGBC and the ILFI within Responsible Sourcing of Materials is a huge accomplishment for the stone industry,” said Kathy Spanier, NSC sustainability committee chair and director of marketing at Coldspring, a Minnesota-based stone industry producer. “These achievements come as the result of tremendous coordination and years of cooperation among stone industry associations, environmental experts and additional stakeholders to further the awareness of sustainably sourced natural stone.”
The NSC established the sustainable stone certification standard in 2014 with two important goals in mind: to provide natural stone quarriers and fabricators with third-party verification of their sustainable practices and to give the building and design community confidence that certified stone is a sustainable material choice.
To develop ANSI/NSC 373 for alignment with LEED and LBC, the NSC Sustainability committee worked closely with third-party organizations including Jack Geibig at Ecoform of Knoxville, TN, and NSF International of Ann Arbor, MI, to determine the sustainable footprint of how stone is quarried, transported and processed. In addition, ANSI/NSC 373 was developed using the consensus-based ANSI (American National Standards Institute) process and can be applied internationally with certification by a third-party certifier like NSF International.
ANSI/NSC 373’s national and international requirements for environmental, ecological, human health, and social responsibility in stone quarrying and processing will help satisfy the growing demand for transparency in the market.
“Natural stone rates high on an environmental scale. It is reusable, low maintenance, emits no VOCs, and is one of the most durable and most beautiful materials on the planet,” said Duke Pointer, executive director of the NSC. “The ANSI/NSC 373 certification gives the market confidence they are using a material that has also been third party verified.”
LEED v4 and LBC Application
The LEED Steering committee approved certification to ANSI/NSC 373 Sustainable Production of Natural Dimensional Stone as a “USGBC approved program” third-party verification (full credit) in option 1 of LEED v4 BD+C and ID+C material resources credit Building Product Disclosure and Optimization – Sourcing of Raw Materials, provided that the facility and/or quarry operation has earned certification including either optional credit 7.2.1 (Ecosystem Boundaries) or 7.2.2 (Environmental Impact Assessment), and has made its scorecard publicly available.
In addition to LEED v4, the Living Building Challenge is advocating the sustainability standard for Natural Dimension Stone for Living Building projects using natural stone. ANSI/NSC 373 aligns within the LBC 3.1 Material Petal, in the Responsible Industry category.
The rigorous and voluntary certification standard including its companion Chain of Custody program is gaining acceptance among stone industry companies. In 2014, TexaStone Quarries, which operates natural stone quarries and a closely aligned fabrication facility in Garden City, TX, became the first company in the world to achieve certification. Coldspring became the second to achieve ANSI/NSC certification of its headquarters, primary manufacturing operations and three Minnesota-based quarries. Additional companies have since certified, with more working to achieve certification.
