    IEQ Credit 4.5: Low-emitting materials - furniture


    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.


    Custom-manufactured furniture components of furniture and their assembly must meet the requirements of IEQ Credit 4.1, Low-Emitting Materials—Adhesives and SealantsA sealant has adhesive properties and is formulated primarily to fill, seal, or waterproof gaps or joints between 2 surfaces. Sealants include sealant primers and caulks. (SCAQMD Rule 1168. )Sealants are used on wood, fabric, paper, corrugated paperboard, plastic foam and other materials with tiny openings, often microscopic, that may absorb or discharge gas or fluid.; IEQ Credit 4.2, Low-Emitting Materials—Paints and Coatings; and IEQ Credit 4.4, Low-Emitting Materials—Composite Wood and Agrifiber ProductsAgrifiber products are made from agricultural fiber. Examples include particleboard, medium-density fiberboard (MDF), plywood, oriented-strand board (OSB), wheatboard, and strawboard..

    Please note that built-in casework and built-in millwork items are considered part of 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)..


    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.1 and seating2 introduced into the project space that have been manufactured, refurbished, or

    refinished within 1 year prior3 to occupancy must meet 1 of the requirements below.

    OPTION 1

    Greenguard Indoor Air Quality Certified


    OPTION 2

    Calculated indoor air concentrations that are less than or equal to those listed 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.


    Option 3

    Calculated indoor air concentrations that are less than or equal to those listed 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 must be independently accredited to ISO/IEC 17025, “General requirements for the competence of testing and calibration laboratories.”

    Chemical Contaminant Emission Limits Systems Furniture Emission Limits Seating
    TVOCThe sum or total of all volatile organic compounds (VOCs) released from a product or measured in a space under certain defined conditions. 0.5 mg/m3 0.25 mg/m3
    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. 50 parts per billion 25 parts per billion
    Total Aldehydes 100 parts per billion 50 parts per billion
    4 – Phenylcyclohexene (4-PCH) 0.0065 mg/m3 0.00325 mg/m3

    1 Systems furniture is defined as either a panel-based workstation comprised of modular interconnecting panels, hang-on components and

    drawer/filing components, or a freestanding grouping of furniture items and their components that have been designed to work in concert.

    Furniture other than systems furniture and task and guest chairs used with systems furniture is defined as occasional furnitureOccasional furniture is located in lobbies and in conference rooms. and is excluded

    from the credit requirements.

    2 Seating is defined as task and guest chairs used with systems furniture

    3 Salvaged and used furniture that is more than 1-year-old at time of occupancy is excluded from the credit requirements.
