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 Sealants; IEQ Credit 4.2, Low-Emitting Materials—Paints and Coatings; and IEQ Credit 4.4, Low-Emitting Materials—Composite Wood and Agrifiber Products.
Please note that built-in casework and built-in millwork items are considered part of the base building.
All systems furniture1 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.
Greenguard Indoor Air Quality Certified
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.
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|
|TVOC||0.5 mg/m3||0.25 mg/m3|
|Formaldehyde||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 furniture and is excluded
from the credit requirements.
