As part of patient care and to meet patient safety requirements on the 13th psychiatric floor, 21 square feet of Tabrasa Ultra Dry Erase Coating has been applied to each of 27 patient rooms. This dry erase coating does not clearly fall within any of the architectural coating categories defined in LEED for Commercial Interiors Version 2.0 IEQ Credit 4.2 Low Emitting Materials Paints and Coatings under South Coast Air Quality Management District Rule 1113. The product does comply under LEED for Schools 2009 IEQ Credit 4.2 Low Emitting Materials Paints and Coatings requirements as defined by the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers. The project team is requesting that this product be acceptable under the LEED for Commercial Interiors Version 2.0 IEQ 4.2 Low Emitting Materials Paints and Coatings." "The project team is asking how to classify dry-erase coatings which are not specifically addressed in South Coast Air Quality Management District Rule 1113. The product regulatory category and credit reporting classification should be determined and declared by the manufacturer. If the regulatory category and classification cannot be determined or the product is a specialty product not otherwise listed in the Table of Standards or defined in the associated Definitions per section (b) , it would fall under the default VOC limit of 250 g/L as per section (c)(1) of South Coast Air Quality Management District Rule 1113 (dated July 09 2004). Alternatively, if the classification cannot be determined or the product is a specialty product, the product\'s compliance with the LEED for Schools 2009 IEQ Credit 4.2 Low Emitting Materials Paints and Coatings requirements for the California Department of Health Services Standard Practice for the Testing of Volatile Organic Emissions from Various Sources Using Small-Scale Environmental Chambers is an acceptable alternative to the SCAQMD Rule 1113 VOC content requirements for healthcare projects. CDPH testing is also acceptable for office projects provided the office testing scenario is used.

"None" "None" "X" "LEED Interpretation" "1167" "2005-06-30" "New Construction" "In the spirit of Resource Reuse, we would like to maintain many of the existing clear finish birch doors. These interior birch wood veneer doors have an existing clear poly sealer. We understand that a water based clear sealers are not recommended for use over the existing oil based poly. The existing finish on the doors cannot be entirely removed because the surface veneer is too thin. The doors will be patched and lightly sanded to accept one coat of a compatible oil based clear sealer. It appears that most manufacturers all have oil base products that have VOC contents of approximately 450 grams/liter. We do not want to compromise the EQ 4.2 credit that the project anticipates achieving. The existing doors that are scheduled to be refinished represent a very very small percentage of the overall surface area that is scheduled for paints and coatings. We are using water based low-VOC products that comply with GS-11 where there are new wood surfaces and no-VOC paint throughout the project on all other surfaces. It is possible to refinish the existing doors off-site, if this would be considered to be a more environmentally friendly approach. We are aware that in 2004, the following credit interpretation was provided for a similar question (see below). It appears that coatings were exempt from the EQ credit 4.2 at the time. It appears that they are not exempt in 2005. For your reference: 7/29/2004 - Credit Interpretation Request We have a lot of cherry wood to be stained and sealed by hand in the building. All available stains and sealers have VOC over 150. I cannot find stain and varnish or polyurethane sealer that meets the VOC requirements specified. Please supply a list materials that can be used with applicable VOCs. We are currently painting the building and meeting all VOCs with Paint. The wood stained off site is meeting the VOCs because of the special process that are able to do at the factory. 9/23/2004 - Ruling The EQc4.2 Credit Ruling dated 12/22/2003 states: - The credit requirements and the referenced Green Seal GS-11 standard apply ONLY to opaque topcoat interior paint, such as that normally applied on walls. Stains and transparent finishes currently fall outside the scope of this credit. For projects wishing to address other coatings, additional low-VOC guidelines can be found in the California Air Resources Board Suggested Control Measures (CARB SCMs), available at: http://www.arb.ca.gov/coatings/arch/rules/ruleinfo.htm (most convenience way to view is in the Excel spreadsheet entitled ""Summary of Architectural Coating rules and VOC limits for U.S. EPA, CARB SCM, Calif. Local Districts"")." "As indicated in the cited CIR, stains and transparent finishes currently fall outside the scope of this credit in LEED-NC Version 2.1, and thus your course of action will not prevent you from achieving EQc4.2 . Please note that the LEED-NCv2.2 draft proposes that all other architectural coatings, primers and undercoats will be addressed with the South Coast Air Quality Management District Rule 1113, Architectural Coatings, in effect on January 1, 2004.

"A Performance/Intent-Equivalent Alternative Compliance Path (PIEACP) is approved for use by LEED for Schools projects. LEED for Schools Project Teams may substitute LEED for New Construction v2.2 EQc4 Low?Emitting Materials credits in place of corresponding LEED for Schools EQc4 Low?Emitting Materials credits. LEED for Schools project teams are encouraged to use LEED for Schools EQc4 Low?Emitting Materials credits where possible, but may substitute LEED for New Construction v2.2 credit requirements as needed.

Volatile organic compound (VOC) limits for aerosol paints appear to be specifically excluded from Green Seal Standard GS-11 and the South Coast Air Quality Management District Rule 1113. Because VOC limits for aerosol paints are not specified by the reference standards or the USGBC LEED-NC v2.2 Reference Guide, please clarify: Are such aerosol ""spray"" paints excluded from the scope of EQ Credit 4.2?" "The project team is seeking guidance on whether aerosol ""spray"" paint is included in the scope of this credit. As noted in the inquiry, aerosol paints are not specifically identified in Green Seal Standard GS-11 and the South Coast Air Quality Management District Rule 1113. The product can therefore be excluded from this credit. Note, that while not a new requirement, please consider that the Environmental Protection Agency does have a new standard in place for aerosol coatings, EPA 40 CFR Parts 51 and 59: National Volatile Organic Compound Emission Standards for Aerosol Coatings (effective December 13, 2007).

The Second Edition of GS-11 (2008) distinguishes between the Primer/Undercoat and Topcoat allowing for 100 g/L for primers/undercoats. The team is seeking to meet the intent of this credit by complying with the updated GS-11 2008 relating to the primers. All other paints and coatings fall below the VOC limits established in GS-11 1993. Is this approach acceptable?" "The LEED-NC v2.2 Reference Guide, Third Edition October 2007, states that all primers must meet the VOC limits for non-flat paint. The alternative standard is therefore not acceptable as a substitute for the current requirement. It should be noted that as needed, a project team can elect to complete a VOC budget to demonstrate compliance. Please refer to page 356 of the LEED-NC v2.2 Reference Guide for additional guidance.

Layout lines and markings applied to resilient athletic flooring often include graphics and lettering; the South Coast Air Quality Management District (SCAQMD) Rule 1113 defines Graphic Arts Coatings as ""coatings formulated for hand-application by artists using brush or roller techniques to indoor and outdoor signs (excluding structural components) and murals, including lettering enamels, poster colors, copy blockers, and bulleting enamels."" Graphic Arts Coatings carries a VOC limit of 500g/L. As indicated above, paints applied to resilient athletic floors do not meet the VOC limits for paint as specified in the credit requirements, however, they are compliant with VOC limits of Graphic Arts Coatings as specified by SCAQMD Rule 1113. Please clarify if roller or brush-applied paint for layout lines and markings would be classified as Graphic Arts Coatings, under SCAQMD rule 1113. If not, please advise how to otherwise achieve the credit requirements. Additionally, graphics applied to textured resilient athletic flooring require air-brushing layout lines and markings; the South Coast Air Quality Management District (SCAQMD) Rule 1113 defines Aerosol Coating Products as ""pressurized coating product containing pigments or resins that dispenses product ingredients by means of a propellant, and is packaged in a disposable can for hand-held application, or for use in specialized equipment for ground marking and traffic marking applications."" VOC limits for Aerosol Coating Products are excluded from Green Seal Standard GS-11, and the South Coast Air Quality Management District rule 1113. The USGBC also ruled on 02/10/2009 that Aerosol Coating Products are excluded from EQc4.2. As paint for floor graphics is loaded into a compressor, and applied using air as the propellant, please clarify if this would be deemed an Aerosol Coating Product, and therefore excluded from this credit. If not, please advise how to otherwise achieve the credit requirements." "The project team is seeking clarification on the applicable standards for paint used for layout lines and markings on athletic flooring. For any roller or brush-applied paint, the proposed reference standard, Graphic Arts Coating for SCAQMD rule 1113 appears to be the appropriate standard for this application. Similarly, when the paint is applied using a compressor and propellant, it would meet the definition of an aerosol coating product, per the same rule. Applicable Internationally. " "None" "None" "X"
