Optional clause
Minimum 15% replacement of Portland cements with fl y-ash (by weight of cement used) in structural
concrete, as per GRIHA (1 point, additional 1 point if more than 30%).
Responsibility: Architect, Project Manager and Structural Consultant
Minimum 40% usage of fl y-ash (by volume of materials used), for 100% load-bearing and no-load
bearing walls, as per GRIHA (2 points).
Responsibility: Architect, Project Manager and Structural Consultant
Minimum 30% replacement of Portland cements with fl y-ash (by weight of cement used) in plaster/
masonry mortar, as per GRIHA (2 points).
Responsibility: Architect, Project Manager and Structural Consultant
Criterion 16 Reduce volume, weight, and construction time by adopting effi cient technologies
(such as pre-cast systems)
Commitment
Replace a part of the energy-intensive materials with less energy-intensive materials and/or utilize
regionally available materials, which use low-energy/energy-effi cient technologies (4 points).
Optional clause
# Structural application: Use of low-energy materials/effi cient technologies in structural application
clearly demonstrating a minimum 5% reduction in the embodied energy, when compared with
equivalent products for the same application, for 100% structural system used in a building,
meeting the equivalent strength requirements, as per all compliance clauses (2 points)
Responsibility: Architect/project manager and structural consultant
# Non-structural application: Use of low-energy materials/effi cient technologies (not based on the
utilization of industrial waste), which are used for non-structural applications such as infi ll wall
system and cause a minimum fi ve per cent reduction in the embodied energy, when compared
with equivalent products for the same application, for 100% infi ll wall system used in a building,
meeting the equivalent strength requirements, as per all the compliance clauses (2 points).
Responsibility: Architect/project manager and structural consultant
Criterion 17 Use low-energy material in interiors
Commitment
Minimum 70% in each of the three categories of interiors (internal partitions, panelling/false ceiling/
interior wood fi nishes/in-built furniture door/window frames, fl ooring) from low-energy materials/
fi nishes to minimize the usage of wood (4 points).
Optional clause
A minimum of 70% of the total quantity (gross area) of all interior fi nishes and products used for
each of the category, as applicable, to be low-energy fi nishes, for each of the following category.
Sub-assembly/internal partitions/panelling/false ceiling/in-built furniture (2 points), as per GRIHA.
Responsibility: Architect
Flooring (1 point), as per GRIHA.
