What is GREEN BUILDING RATING SYSTEM?
A rating system can be defined as a set of prerequisites and requirements that a
project team must fulfil in order to receive certification.
TYPES OF RATING SYSTEM

7. Name: GRIHA is an acronym for Green Rating for Integrated Habitat Assessment.
Country: INDIA
Established : 2007
– GRIHA is a Sanskrit word meaning – ‘Abode’.
– A innovative tool for sustainable development by the united nations
– A tool for implementing renewable energy in the building sector by ‘The
Climate Reality project’- an organization founded by Mr. Al Gore; and UNEP-
SBCI has developed the “Common Carbon Metric” (kWhr/sq m/annum), for
international building energy data collection -based on inputs from GRIHA
(among others)
Introduction Of GRIHA

8. – GRIHA (Green Rating for Integrated Habitat Assessment)
It is India’s own rating system jointly developed by TERI and the Ministry of New and
Renewable Energy, Government of India.
– IGBC (Indian Green Building Council)
LEED is developed by the U.S. Green Building Council (USGBC), the organization promoting
sustainability through Green Buildings.
– BEE (Bureau of Energy Efficiency)
It has star based rating system: more stars mean more energy efficiency. BEE has developed
the Energy Performance Index (EPI). The unit of Kilo watt hours per square meter per year is
considered for rating the building and especially targets air conditioned and non-air
conditioned office buildings.

10. – Minimize a building’s resource consumption, waste generation, and overall
ecological impact
– Evaluates the environmental performance of a building holistically over its
entire life cycle, thereby providing a definitive standard for what constitutes a
‘green building’
– Based on accepted energy and environmental principles, seeks to strike a
balance between the established practices and emerging concepts
– Reduced energy consumption without sacrificing the comfort level
– Reduced destruction of natural areas, habitats, and biodiversity, and reduced
soil loss from erosion etc.
OBJECTIVES OF GRIHA

11. – Two rating systems in India: LEED India and GRIHA
– LEED-India adapted from United States Green Building Council’s (USGBC) is
primarily based on per capita energy consumption in developed nations like the
US which does not work in India since India’s per capita energy consumption is
very low compared to developed nations.
– GRIHA is more suited to Indian climate. Also unlike LEED, it does not promote
usage of certain products like glass and air-conditioning equipment.
WHY CHOOSE GRIHA?

12. – Refuse: To blindly adopt international trends, materials, technologies, products,
etc. Especially in areas where local substitutes are available.
– Reduce: The dependence on high energy products, systems, processes, etc.
– Reuse: Materials, products, traditional technologies so as to reduce the costs
incurred in designing buildings.
– Recycle: All possible wastes generated from the building site, during
construction, operation and demolition.
– Reinvent: Engineering systems, designs and practices such that India creates
global examples that the world can follow rather than India following the
international examples.
5 ‘R’ PHILOSOPHY

13. – Except for industrial complexes, all buildings (offices, institutions, hotels,
hospitals, housing complexes, etc.) in the pre-design/design stage are eligible
for certification under GRIHA.

Straw Bales

35. It is a technology that has been used throughout human civilization for
thousands of years and lasts a very long time. It is a popular and
affordable solution to creating steadfast foundations, floors and walls,
through natural materials such as chalk, earth, gravel or lime, and then
compacting them.
When pressed tightly in wooden forms, it creates walls that have a
similar feel to concrete. Buildings made from rammed earth are made
safer or fortified by the use of rebar or bamboo. Mechanical tamper can
greatly reduce the amount of labor required to create sturdy walls.
Rammed earth walls and floors can be used as thermal storage, allowing
the sun to warm them in the day and slowly release the warmth in the
cooler evenings.
Rammed Earth

36. ➢ It is a concrete-like material created from the woody inner
fibres of the hemp plant. The fibres are bound with lime to
create concrete-like shapes.
➢ lightweight
➢ sturdy
➢ has good thermal and acoustic insulation qualities
➢ fire resistant
➢ Additionally, its biggest sustainable property is that it is CO2
negative, meaning it absorbs more CO2 than it emits.
➢ Hemp itself is a fast-growing and renewable resource.
HempCrete

37. ➢ relatively new material
➢ uses recycled materials such as steel dust from the steel industry,
or ferrous rock leftover from industrial processes, usually sent to
the landfill.
➢ It creates a concrete-like building material, stronger than the
concrete itself.
➢ It traps and absorbs carbon dioxide as part of its drying and
hardening process.
➢ This makes ferrock carbon neutral and a lot less CO2 intensive as
compared to traditional concrete.
➢ It is a viable alternative to cement and can be mixed and poured
to form driveways, staircases, pathways, and more structures.
➢ Some researchers believe ferrock is more resilient to weather
than concrete.
Ferrock

38. ➢ This is an interesting building material and is made from a
mix of sawdust and concrete.
➢ It is lighter than concrete and reduces transportation
emissions.
➢ The sawdust also reuses a waste product and replaces some
of the energy-intensive components of traditional concrete.
Timber concrete could also be formed into traditional shapes
like pavers, bricks and blocks.
Timbercrete

39. ➢ Earthen materials like adobe, cob, and rammed earth are
being used for construction purposes since yore.
➢ For good strength and durability- chopped straw, grass and
other fibrous materials etc. are added to earth.
➢ Even today, structures built with adobe or cob can be seen in
some remote areas.
Earthen Materials

40. ➢ Structural insulated panels (SIPs) consist of two sheets of
oriented strand boards or flake board with a foam layer
between them.
➢ They are generally available in larger sizes and are used
as walls for the structure.
➢ Because of their large size, they need heavy equipment
to install however, they provide good insulation.
SIPs

41. ➢ Slate is naturally formed rock which is used to make
tiles.
➢ Slate tiles have high durability and they are used as
roofing materials.
➢ Slate roofing is preferred when it is locally or
cheaply available.
Slate Roofing

42. Steel roof panels and shingles are highly
durable and they can be recycled again
and again. So, these are the best choices
for green roofing materials.
Steel

43. ➢ Thatch is nothing but dry straw, dry water
reed, dried rushes etc. These are the oldest
roofing materials which are still in use in
some remote locations of the world and
even in cities for aesthetic attractions.
➢ It is cheaply available for roofing and a good
insulator too.
Thatch

44. ➢ Roof panels made of composite materials such as foam or
cellulose layer sandwiched between two metal sheets or
two plastic sheets also come under green building materials.
➢ They are light in weight, inexpensive and provide good
insulation for the structure and save energy.
Composites

45. ➢ Cellulose is a recycled product of paper waste
and it is widely used around the world for
insulation purposes in structure.
➢ It acts as good sound insulator and available for
cheap prices in the market.
Cellulose

46. ➢ Insulated concrete forms contain two insulation layers with
some space in between them. This space contains some
arrangement for holding reinforcement bars, after placing
reinforcement, concrete is poured into this space.
➢ They are light in weight, fire resistant, low dense and have
good thermal and sound insulation properties.
Insulated Concrete Forms

47. ➢ Natural fibers like cotton, wool can also be used as
insulation materials.
➢ Recycled cotton fibers or wool fibers are converted into a
batt and installed in preformed wooden frame sections.
Natural Fiber

48. ➢ Polyurethane foam is available in the form of spray bottles.
They are directly sprayed onto the surface or wall or to which
part insulation is required.
➢ After spraying it expands and forms a thick layer which
hardens later on.
➢ They offer excellent insulation and prevent leakage of air.
Polyurethane

49. ➢ Fiberglass is also used for insulation purposes in the
form of fiberglass batts.
➢ Even though it contains some toxic binding agents,
because of its super insulation property at low cost it
can be considered as a green building material.
Fiberglass

50. ➢ Polystyrene and isocyanurate foam sheets are another type
of insulation materials which are available in the form of
boards or sheets.
➢ These are generally provided as insulators on exterior sides
of a structure, below the grade etc.
Polystyrene and Isocyanurate

51. ➢ Plastering of walls can be done using natural clay rather than
other gypsum-based plasters.
➢ Natural clay plaster with proper workmanship gives a
beautiful appearance to the interior.
Natural Clay

52. ➢ Non-VOC paint or green paint is recommended over VOC
containing paints.
➢ Presence of Volatile Organic Compounds (VOC) in paint
reacts with sunlight and nitrogen oxide resulting in the
formation of ozone which can cause severe health problems
for the occupants.
➢ If non-VOC paint is not available then try the paint with very
low-VOC content in it.
Non-VOC Paints

53. Naturally occurring materials like bamboo, wool and cotton
fiber carpets, cork etc. can be used for flooring purposes.
Natural Fiber Floor

54. ➢ Fiber cement boards are made of cement, sand and wood
fibers.
➢ For exterior siding, fiber cement boards are good choice
because of their cheap price, good durability and good
resistance against fire.
Fiber Cement

55. ➢ Stone is a naturally occurring and a long-lasting building
material.
➢ Some Stone structures built hundreds of years ago are still in
existence without much abrasion.
➢ Stones are good against weathering hence they can be used
to construct exterior walls, steps, exterior flooring etc.
