Are skimming products exempted from this credit IEQ-13

Technical Clarification Number
IEQ13-T-OB1-0825

Guidance
2014-11-05

Project’s request: the filler is specifically defined as cement-based and would qualify for below rational,
"This product is not defined as a paint as it is cement based and acts as a quick drying filler for construction surfaces to which the paint is then applied."

The quantity of skimming product typically would only be a fraction of the quantity of paint area. It would fall in the 80/20 rule. There will be some fillers that DO have VOCs, especially for wood/board, but the overall scale of magnitude is insignificant.

Project team would need to submit the datasheet reflecting Total Calculated VOC even if it is equal to 0.

Revised definition of of VOC datasheets (Replaces IEQ13-T-OB1-0043 issued on 2009-08-23)

Technical Clarification Number
IEQ13-T-OB1-0494

Guidance
2012-06-12

Please note the revised definition of VOC datasheets for the purposes of Green Star SA certification, with reference to paints, adhesives/sealants and carpets in the IEQ-13 credit, a VOC data sheet is defined as follows:
• Compliance certificate or report– Where products have been certified by a third party certification that complies with the same testing methodology and TVOC content limits required by the IEQ-13 credit, certificates and or reports must be provided from the third party certification scheme which confirms the certification of the specific product specified in the project. If not stated on the certificate or report, supporting documents must also be submitted that state the testing method and demonstrate that the TVOC content limits required by the certification body are in line with those set out in the IEQ-13 credit in the Green Star SA Office v1 Technical Manual. For carpets, as the testing method and TVOC limits referenced in the IEQ-13 credit have been based on the Carpet and Rug Institute Green Label (U.S.), for products that are Green Label or Green Label Plus certified, only the compliance certificate need be provided as the testing method and TVOC limits are known to be in line with the requirements of the Green Star SA – Office v1 Technical Manual.
OR
• Laboratory test reports or test certificates – Product TVOC test reports/certificates must be issued by an ISO/IEC 17025 certified testing laboratory and must state the product name, TVOC result and the testing method used. Refer to the Additional Guidance section of the Green Star SA VOC credit for lists of compliant test methods.
OR
• Material Safety Data Sheets (MSDS) – Where a product MSDS includes TVOC information, it must include the numerical result expressed in g/litre of product and the test method used to obtain the results. Refer to the Additional Guidance section of the Green Star SA VOC credit for lists of compliant test methods.
OR
• Manufacturer product data sheet(s) – Official manufacturer datasheets must be provided for each compliant product and must clearly indicate the compliant TVOC levels and state the calculation method used to determine the TVOC levels. The product data sheets must demonstrate that TVOC is based on theoretical calculations of the subtotal of the known VOC values of the product’s raw material components.

Where the TVOC content of individual components is not known, it must be determined experimentally by one of the appropriate test methods listed in the Additional Guidance section of the Green Star SA VOC credit. The manufacturer prepared VOC datasheets must contain the following:
• Numerical TVOC results expressed in g/litre of product (the total VOC content or sum, not the itemized calculation);
• Manufacturer’s statement that the results have been obtained based on the subtotal of the known VOC values of the product’s raw material components.
Alternatively, project teams must submit a signed letter from the manufacturer containing the above requirements. Screen captures of website information is not an acceptable form of documentation to demonstrate a product’s compliance with the Credit Criteria.

Guidance
2012-02-15

In addition to the definition of paint provided in the Technical Manual paint is defined as a liquid solution of pigment in a suitable vehicle of oil, organic solvent, or water; liquid when applied but dries to form an adherent, protective, and decorative coating.

Measurement metric for paints: For demonstrating compliance with the credit criteria, the metric to be used is net surface area painted, regardless of the number of coats applied to a particular surface. Green Star SA always tries to use metrics and methodologies in use by building practitioners. The metric used by quantity surveyors for paint is painted surface area and as such this is the metric used.

For the purposes of this credit, epoxy wall and/or floor coverings, are considered paints, not sealants, and must not exceed 200g/L TVOC content as per the sub-category ‘solvent-based coatings’.

General primers are included in the ‘Interior Sealer’ category of Table IEQ-13.1. Binding primers are included in the 'Timber and binding primers' category.
The maximum TVOC content of ready-to-use paint for walls and ceilings, interior gloss is 75 g/l.

The following uses for sealants and adhesives are considered to represent the most significant portion of these products within buildings and are included within the scope of the IEQ-13 Volatile Organic Compound credit:

• Floor coverings – including carpet and tile adhesives
• Wall coverings – including wallpaper and tile adhesives
• Ceiling and soffit coverings – including adhesives for laminated ceiling tiles or bonded insulation and;
• Skirting board applications.

Adhesive and sealant applications specified for use in/on miscellaneous applications OTHER than those listed above are EXCLUDED from the IEQ-13 Volatile Organic Compound credit scope and are not required to comply with the credit criteria. These include, but are not limited to, piping glues/sealants, window and/or expansion joint sealant.

For compliance with the credit criteria, project teams must demonstrate that 95% of adhesive and sealant products used to fix floor, wall, ceiling and soffit coverings and skirting boards (measured in surface area of use), meet the VOC levels in Table IEQ-13.2: Maximum TVOC Content Limits for Adhesives & Sealants.

“Adhesives”, “sealants” and “paints” for the purposes of Green Star SA, are defined as follows:

Adhesive: A substance capable of holding materials together by bonding the surfaces that are in contact.

Sealant: A material or device used to prevent the passage of liquid or gas across a joint or opening; a sealer.

Paint: A liquid solution of pigment in a suitable vehicle of oil, organic solvent, or water; liquid when applied but dries to form an adherent, protective, and decorative coating.

For the purposes of this credit, epoxy wall and/or floor coverings, are considered paints, not sealants, and must not exceed 200g/L TVOC content as per the sub-category ‘solvent-based coatings’.

Acoustic Sealants and Waterproofing membranes are categorised under the Product Type 'Architectural Sealants' in table IEQ-13.2 and must not exceed a Max TVOC content of 250 g/litre.

Reused items/products are not addressed by this credit and do not need to demonstrate compliance with the Credit Criteria.

Temporary formwork - Adhesives and mastics that are used for temporary formwork are not required to comply with Green Star SA VOC credit criteria. Such materials are not commonly used within enclosed spaces, and as such, the impact on the indoor environment quality of the completed project is negligible.

Non-habitable rooms that open directly to outside or into internal car parking areas may be excluded from the IEQ-13 credit and thus are not required to comply with the credit criteria. Non-habitable rooms that open directly into internal spaces other than internal car parking areas must however be included in the scope of the credit. Examples of non-habitable rooms that may be excluded include store rooms and plant rooms opening directly to outside or into internal car parking areas. Rooms such as security offices, workshops and rooms dedicated for manual waste sorting are however considered habitable and must be included under the credit criteria. See SANS 10400 definition for ‘habitable room’ for further guidance.

Guidance
2012-01-11

The following provides guidance as to the scope of delivery for Conventional, Integrated and Shell & Core:

Conventional Delivery:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with ceilings, finishes (e.g. floor coverings and paint), generic mechanical services (e.g. ducts from air supply and return risers, or other HVAC equipment, with generic control zone/diffuser/return layouts), generic electrical services (e.g. generic lighting layout) and complete wet services. The fitout to tenant areas is intended to be generic and non-tenant specific.

For the purposes of IEQ-13 and a conventional delivery in accordance with the above scope, all applicable paints, adhesives, sealants, carpets and flooring within common areas and tenant areas must comply.

Integrated Fitout:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with ceilings, finishes (e.g. floor coverings and paint), specific mechanical services (e.g. ducts from air supply and return risers, or other HVAC equipment, with fitout specific control zone/diffuser/return layouts), specific electrical services (e.g. fitout specific lighting layout) and complete wet services. The fitout to tenant areas are tenant specific.

For the purposes of IEQ-13 and an integrated fitout in accordance with the above scope, all applicable paints, adhesives, sealants, carpets and flooring within common areas and tenant areas must comply. Loose furniture is not within the scope of IEQ-13.

Shell & Core:
Common Areas - Finishes (e.g. floor coverings and paint) and services are applied to common areas (as applicable).
Tenant Areas - Tenancies are delivered with no ceilings, floor coverings, lighting systems nor partition walls. Mechanical services are not installed within tenant areas, with ducts from air supply and return risers finishing within 1m of the face of the riser (for central air systems), or no other tenant-side systems installed (e.g. indoor units). A raised floor or underfloor air distribution (UFAD) system may be installed in a Shell & Core scenario provided floor coverings are not installed. No fitout is provided in a Shell & Core scenario.

For the purposes of IEQ-13 and a Shell & Core delivery in accordance with the above scope, only applicable paints, adhesives, sealants, carpets and flooring within common areas must comply.

Technical Clarification

Carpet underlay

Technical Clarification Number
IEQ13-T-OB1-0053

Guidance
2010-02-12

Underlay must be included in the carpet product VOC calculations for this credit. Carpet underlay products are to comply with the emission limits stated in ‘Table IEQ-13.3; Carpet TVOC emissions limits’ of the Green Star SA - Office v1 Technical Manual.

 

Technical Clarification

Exempt compounds

Technical Clarification Number
IEQ13-T-OB1-0058

Guidance
2010-02-12

Exempt compounds (based on ASTM D3960 as well as SCAQMD Rule 1168) must be included in TVOC calculations. The exemption for those compounds in the Standards is based on the impact that they have on air pollution, not indoor environment quality (i.e. if the VOC compound did not participate in air pollution reactions, it was exempted from the VOC content). A practice in the industry exists to replace non-exempt compounds (e.g. methyl ethyl ketone) with "exempt compounds" (e.g. acetone) in formulations of paints, coatings and adhesives. While this lowers the TVOC content of the product, it will still have an indoor environment impact. For this reason exempt compounds must be included in TVOC calculations submitted.
