FAQs about IEQc4.2 :

How should graphic arts paint or coatings be categorized?

The standards referenced for this credit have been updated since those listed in the LEED Reference Guide – does our project need to follow the latest SCAQMD Rules and Green Seal editions, or the ones listed in the reference guide?

How should handheld aerosol spray paints be handled?

What are the VOC limits for primers? They seem to be listed in both GS-11 and SCAQMD Rule 1113.

NC-2009 IEQc4.2:Low-Emitting Materials—Paints and Coatings

IEQ Credits 4.1-4.5 - applies to on-site application only?

We are semi-new to the LEED program and want to be sure that we are following all of the necessary guidelines to achieve the overall credits for the project. This is a LEED Gold project intended for a flagship in NYC. We have received some instruction that IEQ Credits 4.1-4.5 applies to our millwork fixtures, even our shop applied adhesives, substrates and finishes. The way I have interpreted these credits is that this applies to on-site application only, not adhesives, stains, substrates or finishes applied in our shop. The statement "..intended to be field applied to stationary structures or their appurtenances.." in Rule 1113 of Architectural Coatings by SCAQMD seems to follow with my assumption. Could someone please verify that we are proceeding correctly?

You have asked about Credits IEQc4.1 through IEQc4.5. Under LEED BD+C-2009, Credit IEQc4.5 only exists under LEED for Schools, LEED-Retail, & LEED-Healthcare, but IEQc4.5 requirements differ depending on which Rating System the Project is using. For example, if the Project is pursuing LEED-Retail, IEQc4.5 requires that manufactured and custom furniture, components of furniture, and their assembly meet the VOC and urea-formaldehyde restrictions required under IEQc4.1, IEQc4.2, and IEQc4.4. Check with the Project’s LEED Administrator to verify which Rating System they are using. Under other LEED-BD+C systems, the texts of Credits IEQc4.1 & IEQc4.2 state that the credit requirements apply only to products “APPLIED ON-SITE.” Therefore, (unless the project is pursuing LEED-Retail) VOC restrictions do NOT apply to adhesives, sealants, paints, and coatings applied during off-site pre-fabrication. By contrast, the IEQc4.4 ban on added urea-formaldehyde resins applies to composite woods, agrifiber products, and laminating adhesives used in assemblies fabricated both on-site and in-the-shop.
