LEED BD+C: Healthcare | v3 - LEED 2009

Low-emitting materials

EQc4 | Possible 4 points

Intent

To reduce the quantity of indoor air contaminants that are odorous, irritating and/or harmful to the comfort and well-being of installers and occupants.

Requirements

One point (maximum four) can be achieved for each group of materials that comply with the requirements.

GROUP 1: Interior Adhesives and Sealants

All adhesives and sealants used on the interior of the building (i.e., inside of the weatherproofing system and applied on-site) must comply with the following requirements as applicable to the project scope1:

  • Adhesives, Sealants and Sealant Primers must comply with South Coast Air Quality Management District (SCAQMD) Rule #1168. Volatile organic compound (VOC) limits listed in the table below correspond to an effective date of July 1, 2005 and rule amendment date of January 7, 2005.
  • Aerosol Adhesives must comply with Green Seal Standard for Commercial Adhesives GS-36 requirements in effect on October 19, 2000.

Adhesives and sealants shall contain no carcinogen or reproductive toxicant components present at more than 1% of total mass of the product as defined in the California Office of Environmental Health Hazard Assessment’s (OEHHA) list entitled “Chemicals Known to the State to Cause Cancer” or the Reproductive Toxicity, Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

GROUP 2: Wall and Ceiling Finishes

Paints and coatings used on the interior of the building—defined as inside of the weatherproofing system and applied on-site—shall not exceed the VOC content limits established in South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings. (Rules in effect on July 1, 2008.)

Ceiling tiles, including suspended acoustical tiles, and wall coverings shall comply with the testing and product requirements of the California Department of Public Health Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers version 1.1 (CDPH/EHLB Standard Method v1.1) modeled using the standard office building protocol parameters and certified as compliant by an independent third party.

GROUP 3: Flooring

Carpet and all hard surface flooring installed in the building interior shall comply with the testing and product requirements of the California Department of Public Health Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions From Indoor Sources Using Environmental Chambers version 1.1
(CDPH/EHLB/M-500 Standard Method v1.1), modeled using the standard office building protocol parameters and certified as compliant by an independent third party. Mineral-based finish flooring products, such as tile,masonry, terrazzo, and cut stone without integral organic-based coatings and sealants and unfinished/untreated
solid wood flooring, qualify for credit without any IAQ testing requirements. However, associated, site-applied adhesives, grouts, finishes and sealers must be compliant for a mineral-based or unfinished/untreated solid wood flooring system to qualify for credit.

All carpet cushion installed in the building interior shall comply with the requirements of the Carpet and Rug Institute Green Label program.

All flooring related adhesives shall comply with the requirements of Group 1. Grout shall comply with requirements for ceramic tile adhesive.

  • For carpet adhesive, concrete, wood, bamboo and cork floor finishes, and tile setting adhesives, compliance can be demonstrated with test results of:
    • Total volatiles fraction, based on one of the following, provided that water and exempt compounds are subtracted from total volatiles test results and the mass VOC content is calculated consistent with SCAQMD Rule 1113 and Rule 1168:
      • ASTM D2369
      • EPA method 24
      • ISO 11890 part 1
    • Total volatile organic compounds fraction, based on one of the following, provided that all VOCs with a boiling point up to 280°C (536°F) are included, and exempt compounds are subtracted from total volatiles test results and the mass VOC content is calculated consistent with SCAQMD Rule 1113 and Rule 1168.
      • ASTM D6886
      • ISO 11890 part 2

Concrete, wood, bamboo, cork and other floor finishes, such as sealer, stain and finish, shall not exceed the VOC limits established in South Coast Air Quality Management District (SCAQMD) Rule 1113, Architectural Coatings, rules in effect on July 1, 2008.

GROUP 4: Composite Wood, Agrifiber Products and Batt Insulation Products

Composite wood and agrifiber products used on the interior of the building—defined as inside of the weatherproofing system—shall contain no added urea-formaldehyde resins. Laminating adhesives used to fabricate on-site and shop-applied composite wood and agrifiber assemblies shall contain no added urea- formaldehyde resins.

Composite wood and agrifiber products are defined as particleboard, medium density fiberboard (MDF),
plywood, wheat board, strawboard, panel substrates and door cores. Materials considered furniture, fixtures, and
equipment (FF&E) are not considered base building elements and are not included.

Batt insulation products shall contain no added formaldehyde, including urea formaldehyde, phenol
formaldehyde, and urea-extended phenol formaldehyde.

GROUP 5: Exterior Applied Products

Adhesives, sealants, coatings, roofing and waterproofing materials—defined as from the weatherproofing system out and applied on-site—shall comply with the VOC limits of California Air Resources Board (ARB) 2007 Suggested Control Measure (SCM) for Architectural Coatings and South Coast Air Quality Management District
(SCAQMD) Rule 1168 effective July 1, 2005.

Roofing installations shall not use hot-mopped asphalt installation techniques.

Parking lots and other paved surfaces shall not use coal tar sealants.

For any waterproofing, asphalt roofing needing repair, parking lot sealing or other high VOC emissions outdoor construction process, create a plan to manage fumes and avoid infiltration to occupied spaces. Comply with procedures established by NIOSH’s Asphalt Fume Exposures During the Application of Hot Asphalt to Roofs
(Publication No. 2003-112).
