Criteria for GRIHA rating 77
Criterion 16 Reduce volume and weight, and time of
construction by adopting effi cient technologies (for
example, pre-cast systems, and so on.)
Objective
Replace a part of energy-intensive materials with less energy-intensive materials and/or utilize
regionally available materials, which use low-energy/energy-effi cient technologies.
16.1 Commitment
16.1.1 Structural application
Use of low-energy technologies/materials (not based on the utilization of fl y ash), such as roofi ng/
fl ooring, columns, and load-bearing walls, for structural applications. Use such technologies
to demonstrate a minimum 5% reduction in the overall embodied energy, when compared to
equivalent products for the same application, for a 100% structural system used in a building, thus
meeting the equivalent strength requirements.
Examples of low-energy products and technologies used in structural applications
Technologies such as pre-stressed slab, extruded structural clay joist and fi ller slab, hollow fl oor/
roof slabs, burned clay fi ller pots with RCC structure, micro-concrete roofi ng, precast hollow plank
roofi ng, funicular shells, zipbloc system, composite columns, reinforced grouted brick masonry,
stone masonry, precast stone blocks, pre-cast concrete blocks, pre-cast fi nished concrete blocks,
light-weight concrete blocks over dense concrete blocks, and rat trap masonry.
16.1.2 Non-structural application: masonry/infi ll wall system
Use of low-energy technologies/materials (not based on the utilization of fl y ash) for non-structural
applications. Use such technologies to demonstrate a minimum 5% reduction in the embodied
energy, when compared to equivalent products for the same application, for 100% infi ll wall system
used in a building, meeting the equivalent strength requirements.
Examples of low-energy product and technologies in non-structural applications
Infi ll wall system using traditional mud walling system, stabilized adobe walling, compressed earth
blocks, hollow, perforated/ modular bricks, interlocking bricks, traditional stone masonry, pre-cast
non-load-bearing concrete blocks, fi nished concrete blocks, light weight concrete blocks over dense
concrete blocks, pre-cast brick panels, composite ferrocement walling, interlocking concrete blocks,
rat trap masonry, and so on.
16.2 Compliance
The following documents are to be submitted.
16.2.1 Cut sheets, specifi cation sheets and bill of quantity demonstrating the percentage reduction
in embodied energy with the use of low-energy materials/effi cient technologies.
16.2.2 Document to demonstrate the use of the aforesaid technologies in the relevant fl oor plans,
with clear dimensions and enlisting of specifi cations.
