IEQ c4.3: Low-emitting Materials—flooring Systems
To establish minimum indoor air quality (IAQ) performance to enhance indoor air quality in buildings, thus contributing to the comfort and well-being of the occupants.
All flooring must comply with the following as applicable to the project scope:
• All carpet installed in the building interior must meet the testing and product requirements of the Carpet and Rug Institute Green Label plus 1 program.
• All carpet cushion installed in the building interior must meet the requirements of the Carpet and Rug Institute Green Label program.
• All carpet adhesive must meet the requirements of IEQ Credit 4.1: Adhesives and Sealants, which includes a volatile organic compound (VOC) limit of 50 g/L.
• All hard surface flooring must be certified as compliant with the Floor Score 2 standard (current as of the date of this rating system, or more stringent version) by an independent third-party. Flooring products covered by Floor Score include vinyl, linoleum, laminate flooring, wood flooring, ceramic flooring, rubber flooring and wall base.
• An alternative compliance path using Floor Score is acceptable for credit achievement: 100% of the non-carpet finished flooring must be Floor Score-certified and must constitute at least 25% of the finished floor area. Examples of unfinished flooring include floors in mechanical rooms, electrical rooms and elevator service rooms.
• Concrete, wood, bamboo and cork floor finishes such as sealer, stain and finish must meet the requirements of South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings, rules in effect on January 1, 2004.
• Tile setting adhesives and grout must meet South Coast Air Quality Management District (SCAQMD) Rule 1168. VOC limits correspond to an effective date of July 1, 2005 and rule amendment date of January 7, 2005.
All flooring elements installed in the building interior must meet the testing and product requirements of the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers, including 2004 Addenda.
Potential technologies & Strategies
Clearly specify requirements for product testing and/or certification in the construction documents. Select products that are either certified under the Green Label Plus program or for which testing has been done by qualified independent laboratories in accordance with the appropriate requirements.
All flooring elements installed in the building interior have been met the testing and product requirements of the referenced standards for this credit.
