Criteria for GRIHA rating 89
Health and well-being
Building construction and its operation aff ects the health and well-being of people in many ways.
Green building practices and measures should be integrated into the design process to ensure the
health and well-being of the occupants.
Criterion 26 Use low-VOC paints/adhesives/sealants
Objective
To select and use paints, adhesives and sealants with low quantities of chemical substances and
VOCs (especially formaldehyde, uria formaldehyde and urethanes).
26.1 Commitment
26.1.1 Use only zero/low VOC paints. All paints used in the interior of the building (defi ned as
inside of the weather proofi ng systems and applied onsite) must be certifi ed to contain
zero VOC or less than the limits specifi ed in GRIHA.
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 off er adequate bond strengths
in water-based varieties. Acrylics, silicones, and siliconized acrylics are the safest sealants
for use in the 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
exterior do not pose any concern.
26.1.4 Adhesive 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 all composite wood products/agri –fi bre products do not contain any added urea
formaldehyde resin.
26.2 Compliance
The following documents should be submitted
26.2.1 Cut sheets, specifi cation sheets, and commercial brochures of the low VOC-emission fi nishes
or products used.
26.2.2 A certifi cate from the manufacturer for each of the category as applicable to the applicant,
clearly stating that the materials used have zero VOCs or low VOCs (gms/litre) as specifi ed
under limits.
26.2.3 The bill of quantity for each of the category, as applicable, clearly demonstrating that 100%
of all the interior paints, sealants, adhesives, and composite wood/agri-fi bre products meet
the mentioned criteria.
