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.
All adhesives and sealants used on the interior of the building (i.e., inside the weatherproofing system and applied onsite) must comply with the following requirements as applicable to the project scope1:
Paints and coatings used on the interior of the building (i.e., weatherproofing system and applied onsite) must comply with the following criteria as applicable to the project scope2:
All flooring must comply with the following as applicable to the project scope:
If a European testing method (AgBB/DIBt GUT, EMICODE, Blue Angel) had used parameters for calculating test results different from those specified in the referenced California method, then the European test results for carpets or floorings need to be converted into California air concentrations by multiplication with 0.7.
All flooring products 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.
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.
Composite wood and agrifiber products used on the interior of the building (i.e., inside the weatherproofing system) must contain no added urea-formaldehyde1. Formaldehyde is a naturally occurring VOC found in small amounts in animals and plants but is carcinogenic and an irritant to most people when present in high concentrations, causing headaches, dizziness, mental impairment, and other symptoms. When present in the air at levels above 0.1 ppm, it can cause watery eyes; burning sensations in the eyes, nose, and throat; nausea; coughing; chest tightness; wheezing; skin rashes; and asthmatic and allergic reactions.
2. A known carcinogen with no known safe exposure level. Formaldehyde occurs naturally, but appears in unnaturally high concentrations in many buildings because it is an ingredient in binders used in many building materials and furnishings. resins. Laminating adhesives used to fabricate onsite and shop-applied composite wood and agrifiber assemblies must not contain added urea-formaldehyde resins. Please note that built-in casework and built-in millwork items must be included in the base buildingThe base building includes elements such as the structure, envelope, and building-level mechanical systems, such as central HVAC, and materials and products installed in the project (e.g., flooring, casework, wall coverings). calculations.
Products covered by IEQ Credit 4, Option E—Furniture shall be excluded from these requirements
For manufactured and custom furniture, components of furniture and their assembly must meet the requirements of IEQ Credit 4, Option A: Adhesives and Sealants, IEQ Credit 4 Option B—Paints and Coatings, and IEQ Credit 4, Option D: Composite Wood and Agrifiber Products.
Please note that built-in casework and built-in millwork items are to be considered part of the base building.
All systems furnitureSystems furniture includes panel-based workstations comprising modular interconnecting panels, hang-on components, and drawer and filing components or a free-standing grouping of furniture items designed to work in concert.4 and seating5 introduced into the project space that have been manufactured, refurbished,
or refinished within 1 year prior6 to occupancy must meet 1 of the requirements below.
Greenguard Indoor Air Quality Certified
Calculated indoor air concentrations that are less than or equal to those established in Table 1 for furniture systems and seating determined by a procedure based on the EPA Environmental Technology Verification (ETV) Large Chamber Test Protocol for Measuring Emissions of VOCs and Aldehydes (September 1999) testing protocol conducted in an independent air quality testing laboratory.
Calculated indoor air concentrations that are less than or equal to those established in Table 1 for furniture systems and seating determined by a procedure based on ANSI/BIFMA M7.1–2007 and ANSI/BIFMA X7.1–2007 testing protocol conducted in an independent third-party air quality testing laboratory.
The requirement in ANSI/BIFMA X7.1–2007, Section 5, is waived for LEED purposes. Section 5 requires that laboratories used to perform the emissions testing and/or provide analytical results shall be independently accredited to ISO/IEC 17025, “General requirements for the competence of testing and calibration laboratories.”
All gypsum board, insulation, acoustical ceiling systems, and wall coverings installed in the building interior shall 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.
Does anyone know which categories of low emitting materials is the self-leveling compound ?
I'm trying to determine if certain materials will apply for the purposes of the EQc4.6 credit for low-emitting ceiling and wall systems. My project will be installing custom-shaped glass-fiber reinforced gypsum. I couldn't find any information on any equivalent materials that are Greenguard certified, and I'm not certain that it even applies to this credit. Also, are wall fabrics included? Thanks for any feedback!
Carly, the credit language specifies that "All gypsum board, insulation, acoustical ceiling systems, and wall coverings installed in the building interior" are subject to the credit scope.
That's a definite yes on wall fabrics. For your custom-shaped gypsum product, hard to day without knowing more about its function, but it seems likely.
Thanks Tristan. After looking more into the plans, the shaped GFRG will make up a curved cornace, fascia and and vaulted ceiling, Since they specifically call out acoustical ceiling systems in the credit requirements, I think this product might be off the hook. It will be a while before a construction review takes place for this particular job but I'll plan to follow up on this post if we do end up pursuing the credit.
