Hanstone Certification & Policy

Building Today and Tomorrow’s Green in Mind

Hanwha L&C, part of the Hanwha Group conglomerate, is a member of the U.S. Green Building Council (USGBC), the promulgator of Leadership in Energy and Environmental Design™ (LEED®) green building guidelines.


LEED Points Available with Hanwha L&C | Surfaces Products

We offer products which support a building project’s effort to achieve certification under the US Green Building Council’s LEED® (Leadership in Energy and Environmental Design) Green Building Rating System™. Our environmentally friendly manufacturing processes and products may also satisfy other requirements for projects that desire to incorporate “green” materials.

What is the Leed Green Building Rating System?

The LEED (Leadership in Energy and Environmental Design) Green Building Rating System is a voluntary standard for developing environmentally responsible, low emission, high-performance, sustainable buildings. Individual materials and products used in buildings are not certified. The Version 2.1 certification process is for the entire construction project. The project earns “points” towards becoming certified. The categories where points can accumulate for Global partition products are as follows: Local Regional Materials: LEED V2.1 awards 1 point if 20% of the building materials are manufactured (final assembly) regionally within 500 miles of the project site. This contributes to Credit 5.1 of the “Materials & Resources” area.

Materials & Resources (Building Reuse): LEED V2.1 awards 1 point if the material maintains 100% of existing building structure and shell (exterior skin and framing) and at least 50% of non-shell areas (floor coverings, walls, doors, and ceilings).

Low Emitting Materials: LEED V2.1 awards 1 point (Credit 4.1 of “Indoor Environmental Quality” area) if the VOC content of adhesives is less than the current limit specified in SCAQMD Rule #1168, and 1 point (Credit EQ 4.4) if the engineered wood and agri-fiber products contain no added urea-formaldehyde resins.

Hanwha Surface Products qualify for LEED Certification points as follows:

LEED Category: Possible Points
Materials & Resources
1 max
Credit (1pt): HanStone Quartz is highly durable and will remain so throughout the life of the building. If the requirements to existing building structure and shells are met, the use of HanStone products can contribute Leed points in this category.

Low Emitting Materials
1 max (EQ4.1)
Credit (1pt): The joint sealants and adhesives used in HanStone Quartz installations have low VOC emissions and fall within the current standard set by both the Bay Area Air Quality Management Districts and SCAQMD

Green Guard

GREENGUARD and Green Guard Education

The GREENGUARD Environmental Institute (GEI) is an industry-independent, non-profit organization that oversees the GREENGUARD Certification Program. As an ANSI Authorized Standards Developer, GEI establishes acceptable indoor air standards for indoor products, environments, and buildings. GEI’s mission is to improve public health and quality of life through programs that improve indoor air. A GEI Advisory Board consisting of independent volunteers, who are renowned experts in the areas of indoor air quality, public and environmental health, building design and construction, and public policy, provides guidance and leadership to GEI.

About the GREENGUARD Indoor Air Quality Certification Program for Low-Emitting Products

The GREENGUARD Certification ProgramSM is an industry-independent, third-party testing program for low-emitting products and materials. The first GREENGUARD Certification was awarded in the fall of 2002. In 2005, GEI announced the GREENGUARD Children & Schools standard, which evaluates the sensitive nature of school populations combined with the unique building characteristics found in schools, and presents the most rigorous product emissions criteria to date. To date, more than 100 manufacturers across various industries offer GREENGUARD Indoor Air Quality Certified® Products.

All GREENGUARD Certified products are listed in the GREENGUARD Online Product Guide, an indoor air quality (IAQ) resource that is provided at no charge. The guide features products, which are regularly tested to ensure that their chemical and particle emissions meet acceptable IAQ pollutant guidelines and standards. GREENGUARD Certification is a valuable tool for architects, designers, product specifiers, and purchasing organizations that want to locate, specify, and purchase off-the-shelf, low-emitting products for indoor environments. GREENGUARD Certification is a voluntary program available to all manufacturers and their suppliers.

About the GREENGUARD for Building Construction™ Program

In 2006, GEI introduced the GREENGUARD for Building Construction Program, a mold risk reduction program that for the first time certifies the design, construction and ongoing operations of newly constructed multifamily and commercial properties. GREENGUARD for Building Construction protects Lenders, Insurers and Building Developers from Mold Risk by providing effective processes based on the industries’ best practices for safeguarding against the damage and resulting losses caused by mold. Buildings that are “certified” through GREENGUARD for Building Construction have been proven to meet this standard and are monitored for ongoing compliance throughout the term of the loan or building life.
