26. 1 Commitment
26.1.1 Use only zero or low VOC paints. All paints used in the interior of the building (defined
as inside of the weatherproofing system and applied on-site) must be certified to
contain zero VOC or less than the limits specified as follows.
Table 26.1 VOC limits for paints
Paint applications VOC limits (grams of VOC per litre)
Flat <50
Interior coatings
Non-lat <150
Flat <200
Exterior coatings
Non-lat <100
Anti corrosive Gloss, semi gloss, lat <250
26.1.2 Prefer water-based acrylics over solvent-based oil paints.
26.1.3 Ensure all the sealants and adhesives used are water-based rather than solvent-based
or have a low solvent content. Most construction adhesives offer adequate bond
strengths in water-based varieties. Acrylics, silicones, and siliconized acrylics are the
safest sealants for use in interiors and have the lowest solvent content. While solvent-
based products, such as urethanes and butyls, should preferably not be used indoors,
sealants used for the exterior do not pose any concern.
26.1.4 Adhesives usually have a high VOC emission potential. Hence, use adhesives with low-
VOC or no-VOC emissions such as acrylics or phenolic resins (phenol formaldehydes
indoors).
26.1.5 Ensure that all the composite wood products and agri-fibre products do not contain
any added urea formaldehyde resin.
26.2 Compliance
The following documents are to be submitted.
26.2.1 Cut sheets, specification sheets, and commercial brochures of the low VOC emission
finishes or products used.
26.2.2 A certificate from the manufacturer for each of the category as applicable to the
applicant, clearly stating that the materials used have no VOC or low VOC (grams/litre),
as specified in Table 26.1.
26.2.3 The bill for the quantity for each of the categories, as applicable, clearly demonstrating
that 100% of all the interior paints, sealants, adhesives, and composite wood/ agri-fibre
products meet the mentioned criteria.
26.3 Appraisal (maximum points – 3)
26. 3. 1 Zero/low VOC paints: Zero/low VOC paints for 100% of all paint used in the interior of
the building (1 point), as per clauses 26.2.1, 26.2.2, and 26.2.3.
26.3.2 Low-VOC sealants and adhesives: 100% of all the sealants and adhesives used are water
based rather than solvent based/ low solvent content (1 point), as per clauses 26.2.1,
26.2.2, and 26.2.3.
26.3.3 100% of composite wood products with no urea-formaldehyde resins (1 point), as per
clauses 26.2.1, 26.2.2, and 26.2.3.
