IEQ-13 VOLATILE ORGANIC COMPOUNDS

 

Technical Clarification

GUT certification as alternative compliance to CRI for carpets

Technical Clarification Number
IEQ13-T-RC1-1198

Guidance
2016-01-19

The GBCSA confirm that the Association of Environmentally Friendly Carpets e.V. (Gemeinschaft umweltfreundlicher Teppichboden) – GUT – is deemed to be an acceptable alternative to CRI (Carpet and Rug Institute Green Label) compliance with regards to TVOC levels and testing methodology for carpets. Project teams may utilise product specific GuT certificates as supporting evidence.

 

Technical Clarification

Volatile Organic Compounds and 'Shell & Core' spaces

Technical Clarification Number
IEQ13-T-RC1-0365

Guidance
2013-07-22

The following guidance is provided for spaces delivered as ‘Shell & Core’, as defined in the Green Star SA Retail Centres v1 Technical Manual.

Paints
Regardless of delivery type (i.e. Conventional, Integrated or Shell & Core), the scope of the credit criteria is applicable to all paints applied to the base building, excluding paints used in internal car parks and for exterior applications.

Adhesives & Sealants
Regardless of delivery type (i.e. Conventional, Integrated or Shell & Core), the scope of the credit criteria is applicable to all adhesives and sealants applied to base building, excluding adhesives and sealants used in internal car parks and for exterior applications.

Carpets & Floor Coverings
Regardless of delivery type (i.e. Conventional, Integrated or Shell & Core), the scope of the credit criteria is applicable to all carpets and flooring installed within the base building, excluding carpets and flooring used in internal car parks and for exterior applications.

 

Technical Clarification

Exempt compounds

Technical Clarification Number
IEQ13-T-RC1-0058

Guidance
2012-06-08

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.

Paints – additional guidance for defining and documenting paint product types and associated TVOC. (Replaces IEQ13-T-RC1-0291 issued 2012-01-11; IEQ13-T-RC1-0016 issued 2009-02-06; and IEQ13-T-RC1-0059 issued 2010-02-12)

Guidance

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.

Adhesives & Sealants - Scope of Products and additional guidance for defining and documenting product types and associated TVOC.(Replaces IEQ13-T-RC1-0055 issued 2010-02-12, IEQ13-T-RC1-0057 issued 2010-02-12, and IEQ13-T-RC1-0338 issued 2011-11-10)

Technical Clarification Number
IEQ13-T-RC1-0424

Guidance
2012-06-08

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.

Guidance
2012-06-08

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.
