Objective
Replace a part of energy-intensive materials with less energy-intensive materials and/or utilize
regionally available materials, which use low-energy/energy-efficient technologies.
16.1 Commitment
16.1.1 Structural application
Use low-energy technologies/materials (not based on the utilization of fly ash), such as roofing/
flooring, columns, and load-bearing walls, for structural applications. Such technologies lead to
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 filler slab, hollow
floor/roof slabs, filler slabs or burned clay filler pots with RCC structure, micro-concrete roofing,
pre-cast hollow plank roofing, funicular shells, zipbloc system, composite columns, reinforced
grouted brick masonry, stone masonry, pre-cast stone blocks, light-weight concrete blocks over
dense concrete blocks, and rat trap masonry.
16.1.2 Non-structural application: masonry/inill wall system
Use of low-energy technologies/materials (not based on the utilization of fly ash) for non-
structural applications. Such technologies lead to minimum 5% reduction in the overall
embodied energy, when compared to equivalent products for the same application, for 100%
infill wall system used in a building, meeting the equivalent strength requirements.
examples of low-energy product and technologies in non-structural applications
infill 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, finished 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, specification sheets, and bill of quantity demonstrating the percentage
reduction in embodied energy with the use of low-energy materials/efficient
technologies.
16.2.2 Document to demonstrate the use of aforesaid technologies/materials in the relevant
floor plans, with clear dimensions and enlisting of specifications.
16.2.3 Narrative showing how the selected technology/material has amounted to reduction in
high-energy materials or regional availability when compared with equivalent products
for the same application. On-site photographs and construction project management
