5. ❏ NAME: GRIHA
❏ COUNTRY: INDIA
❏ ESTABLISHED: 2007
GRIHA (Green Rating for Integrated Habitat Assessment)
● GRIHA is developed by TERI (The energy and Resources Institute) for the ministry of new and
Renewable energy. This is the indigenous national rating system developed by the ministry to cover the
climatic variations, architectural practices, existing practices of construction and attempting to revive the
passive architecture.
● GRIHA rating system takes into account the provisions of the National Building Codes 2005 , The energy
conservation Building Code 2007 announced by BEE and other IS codes.
● The rating system based on accepted energy and environmental principles, seeks to strike a balance
between the established practices and emerging concepts, both National and International.

6. WHAT ROLE DOES GRIHA PLAY?
● They encourage non energy demanding air conditioning systems and the solar heating systems. Passive cooling
and heating can be replicated for the masses and can reduce the energy load of the country.
● GRIHA is also focusing on the growing residential sector by providing simple, affordable and versatile
approach to the citizens through their website, which is instrumental in creating awareness among citizens as
well as giving them an alternative viewpoint.
● GRIHA is also promoting energy efficiency in existing buildings in urban areas which will in return reduce
energy demand.
OBJECTIVES OF GRIHA
● 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.

9. THE 5 ‘R’ PHILOSOPHY
1. Refuse –to blindly adopt international trends, materials, technologies, products, etc. Specially in
areas where local substitutes/equivalents are available
2. Reduce – the dependence on high energy products, systems, processes, etc.
3. Reuse – materials, products, traditional technologies, so as to reduce the costs incurred in designing
buildings as well as in operating them
4. Recycle – all possible wastes generated from the building site, during construction, operation and
demolition
5. Reinvent – engineering systems, designs, and practices such that India creates global examples that
the world can follow rather than us following international examples

10. GRIHA VERSION 2015
The GRIHA V 2015 rating system consists of 31 criteria categorized under various sections such as
● Site Planning, Construction Management
● Occupant Comfort and Wellbeing
● Sustainable Building Materials
● Performance Monitoring and Validation
● Innovation Eligibility
All buildings, which are in the design stage and have built up area more than 2,500 m2, are eligible for certification
under GRIHA.
GRIHA assesses a building out of 34 criteria and
awards points on a scale of 100. In order to qualify for
GRIHA certification, a project must achieve at least 50
points.
GRIHA ASSESSMENT CRITERIA

11. GRIHA VERSION 2019
The overall sequence of criteria and their appraisals has
been changed in the GRIHA v.2019. This version now has
11 sections subdivided into 30 criteria.
The new criteria that have been added in the rating system
are :
● Green infrastructure
● Commissioning for final rating
● Reduction in CO2 emission of the building
● Alternative building materials for external site
development
● Life cycle cost analysis
● Water quality and self-sufficiency
● Positive social impact

12. GRIHA VARIANTS
Griha Rating System Variants of
Griha:
● Svagriha For Building
Area- 100-2499 Sqm
● Griha For Building Area-
2500-1,50,000 Sqm
● Griha Ld For Building
Area-> 50 Hectare Site

13. SVAGRIHA PRE-CERTIFICATION
SVAGRIHA (Simple Versatile Affordable GRIHA) was jointly developed by
GRIHA Council and TERI. SVAGRIHA is a significantly simplified, faster, easier
and more affordable rating system that eventually functions as a design-cum-rating
tool. In order to facilitate projects to assess their performance during designing
stage, and avail incentives from local authorities, wherever applicable, a
precertification rating was introduced. This rating assesses the commitment of
project team towards following the SVAGRIHA norms in future, and provides
them with a rating between 1 star to 5 star.
SVAGRIHA CERTIFICATION
SVAGRIHA
SVAGRIHA (Simple Versatile Affordable GRIHA) was jointly developed by GRIHA Council and TERI.
SVAGRIHA is a significantly simplified, faster, easier and more affordable rating system and will eventually
function as a design-cum-rating tool. It was required that attention be paid to smaller buildings in India which
although have small individual environmental footprints but their cumulative effect is far bigger.
SVAGRIHA can help in design and evaluation of individual residences, small offices, schools, motels, commercial
buildings etc.

14. ELIGIBILITY
SVA GRIHA is applicable only for projects which are less than 2500 sq m built-up area. Any building, except
for a factory building, are is accepted under the SVAGRIHA rating system.
● The rating system has 14 criteria.
● Beyond the pilot-phase, the tool will be converted into a
web-tool.
● The criteria are divided into 5 broad sub-groups-namely:
energy, water and waste, materials, landscape and others.
● It will be mandatory to attempt certain points under each
sub-group. This has been detailed in further sections.
● The total points that a project can achieve are 50
● The rating will be done on a 1-5 star scale.

16. GRIHA
GRIHA PRE-CERTIFICATION
GRIHA Council proposed a procedure that will enable fast track environmental clearance through GRIHA pre-
certification. In order to facilitate projects to assess their performance during designing stage, and avail incentives
from local authorities, wherever applicable, a precertification rating was introduced.
Except for industrial complexes, all buildings - offices, retail malls, institutions, hotels, hospitals, health-care
facilities, residences and multifamily high rise buildings - in the pre-design/ design stage are eligible for pre -
certification under GRIHA.
● For built up area greater than 20,000 sq. mtr
Projects applying for Environmental Clearance from MoEF are eligible to apply under this category. Please
note that it is mandatory to register the project under GRIHA rating after precertification has been awarded.
● For built up area less than 20,000 sq. mtr
Projects can register for GRIHA pre-certification and GRIHA rating at the same time. The registration- cum-
rating fee for both the processes must be submitted upfront by the project proponent to complete the
registration process.

17. GRIHA CERTIFICATION
With our growing technological skills, buildings have also been increasingly
designed and operated to place exorbitant demands on natural resources, such as
land, water, and energy, to mention a few. Therefore, incorporation of sustainable
practices in building design and operation is no longer a choice but a necessity for a
sustainable future.
The GRIHA v.2015 has undergone an extensive revision to account for the ongoing
advancements in the highly dynamic construction sector. This version (i.e. GRIHA
v2019) integrates concepts like life cycle cost analysis, life cycle analysis, and
water performance index to name a few. This version has taken into consideration
the incorporation of user experience, market feedback, and enhanced ease of
implementation and adoption.
All new construction projects with built up area more than 2500 m2 (excluding
parking, basement area, and typical buildings) are eligible for certification under
GRIHA v.2019.

19. GRIHA FOR AFFORDABLE HOUSING
In line with its philosophy and with the purpose of taking sustainability to the masses,
GRIHA has developed a new rating variant called as "GRIHA for Affordable Housing"
which is aligned to the PMAY. With the help of GRIHA AH rating, many low-
income households shall be able to reduce the operational costs and GHG
emissions by improving their resource efficiency. The rating would evaluate the
environmental performance of residences holistically over its entire life cycle. The
rating thus provides a definitive standard for what constitutes a 'green building' as it is a
dedicated assessment cum rating tool, and a pre-fed calculator based system.
● All the upcoming projects that have approval/sanction letter issued by government agency (Central/State)
confirming that the project is being developed as per Pradhan Mantri Awas Yojana (PMAY) are eligible
for GRIHA AH rating.
● Affordable Housing project boundary must comply with the applicable municipal, state and local building
bylaws related to environment and regulations in place where the project is located

The intent of GRIHA LD is to provide a consolidated framework for assessment
of environmental impacts of large scale developments.
Qualification for rating
All projects which satisfy either of the following two thresholds may apply for a
GRIHA LD rating:
● Total site area greater than or equal to 50 hectares.

24. In GRIHA LD the development will be evaluated in six different sections as
listed below:
● Site Planning
● Energy
● Water and waste-water
● Solid waste management
● Transport
● Social

25. GRIHA FOR CITIES
The GRIHA for CITIES rating has been structured as a framework for sustainable
development of a city, to be achieved by measuring 'greenness' of existing as well as
proposed cities . Qualitative and quantitative criteria have been integrated in the rating
to cover diverse aspects of sustainable development. The rating sets performance
benchmarks for key resources such as energy, water and waste; and evaluates the
project's performance in areas such as smart governance, social wellbeing, and
transportation .
The rating targets all cities, towns with civic/local bodies, such as Municipal Corporation and Municipal Council.
Urban agglomerations having more than one civic body can go for rating in phases as well. The municipal limits
of the urban area shall be considered as the boundary for rating purposes. The civic bodies for the rating can be
classified as urban local bodies (ULBs) with population less than 1 lakh and ULBs with population greater than 1
lakh.
Any city which is undergoing land acquisition or is in the planning phase shall be considered as new. If the
implementation has not started, the civic body can submit policies/plans/calculations/drawings or other relevant
documents. The implementation status shall be verified during the course of the project certification.
