LEED Indoor Envir onmental Quality 269

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
Option 1 in LEED 2009 (for carpet systems) All carpet installed in the building interior shall
meet the testing and product requirements of the Carpet and Rug Institute’s Green Label
Plus program.
All carpet cushion installed in the building interior shall meet the requirements of the
Carpet and Rug Institute Green Label program.
All carpet adhesive shall meet the requirements of IEQ Credit 4.1: VOC limit of 50 g/L
(the units are in grams of VOCs per liter of product minus water).
(Potential Technologies and Strategies for Carpet Systems)
Clearly specify requirements for product testing and/or certification in the construction
documents. Select products either that are certified under the Green Label Plus program
or for which testing has been done by qualified independent laboratories in accordance
with the appropriate requirements. The Green Label Plus program for carpets and its
associated VOC emission criteria in micrograms per square meter per hour, along with
information on testing method and sample collection developed by the Carpet and Rug
Institute (CRI) in coordination with California’s Sustainable Building Task Force and the
California Department of Health Services (DHS), are described in Section 9, Acceptable
Emissions Testing for Carpet, DHS Standard Practice CA/DHS/EHLB/R-174, dated
07/15/04. This document is available at http://www.cal-iaq.org/VOC/Section01350_7_
15_2004_FINAL_PLUS_ADDENDUM-2004-01.pdf. [It is also published as Section 01350
Section 9 (dated 2004) by the Collaborative for High Performance Schools (www.chps.

LEED 2009 Option 1 Flooring Systems and Additional Option 2
LEED 2009 Option 1 has the additional requirements for non-carpet flooring systems:
• All hard surface flooring must be certified as compliant with the FloorScore standard
(current as of the date of the LEED 2009 rating system or any more stringent version) by
an independent third party. Flooring products covered by FLoorScore include vinyl,
linoleum, laminate flooring, wood flooring, ceramic flooring, rubber flooring and wall
base.
• An alternative compliance path using FloorScore is acceptable for credit
achievement: 100% of the non-carpet finished flooring must be FloorScore certified
and must constitute at least 25% of the finished floor area. Examples of unfinished
flooring include floors in mechanical rooms, electrical rooms and elevator service
rooms.
• Concrete, wood, bamboo and cork floor finishes such as sealer, stain and finish must
meet the requirements of SCAQMD Rule 1113, Architectural Coatings, rules in effect
on January 1, 2004.
• Tile setting adhesives and grout must meet SCAQMD Rule 1168. VOC limits
correspond to an effective date of July 1, 2005 and rule amendment date of January 7,
2005.
OPTION 2
LEED 2009 provides a second option for any of the flooring systems such that all flooring
elements in the building interior 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.
