IEQ Credit 4.4: Low-Emitting Materials—Composite Wood
and Agrifiber Products

USGBC Rating System
LEED NC 2.2 lists the Intent, Requirements, and Potential Technologies and Strategies
for IEQc4.4 as follows, with additions to reflect the LEED 2009 version:

Intent
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
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, wheatboard, strawboard, panel substrates and door cores. Fixtures, furniture,
and equipment (FF&E) are not considered base building elements and are not included.
Potential Technologies and Strategies
Specify wood and agrifiber products that contain no added urea-formaldehyde resins.
Specify laminating adhesives for field and shop applied assemblies that contain no added
urea-formaldehyde resins.
Calculations and Considerations IEQ Credit Subcategory 4: Low-Emitting Materials
The various referenced rules and organization standards can be found at the following
websites:
• The SCAQMD Rule #1168 can be found at http://www.aqmd.gov/rules/reg/
reg11/r1168.pdf. The Rule 102 which gives the definition of exempt compounds
and other definitions in Rule #1168 can be downloaded from http://www.
aqmd.gov/rules/reg/reg01/r102.pdf. The exempt compounds are a group of
mainly hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and
chlorofluorocarbons (CFCs). They are considered to be less reactive than most
other VOCs with respect to the production of tropospheric ozone, although
many are now banned due to their stratospheric ozone depletion potential. (Refer
to IEAp3 and IEAc4 for more information on the ozone depletion potential.)
