GRIHA | Green Rating for Integrated Habitat Assessment | PPT

The Green Rating for Integrated Habitat Assessment (GRIHA) is a comprehensive national rating system developed in India to evaluate the environmental performance of buildings over their entire lifecycle. Established by The Energy and Resources Institute (TERI) and endorsed by the Ministry of New and Renewable Energy (MNRE), GRIHA emphasizes sustainability through various stages of construction and operation. It focuses on key areas such as energy efficiency, water conservation, waste management, and indoor air quality. By promoting resource optimization and reducing environmental impact, GRIHA aims to foster sustainable building practices. The rating system awards points based on compliance with its criteria, encouraging developers and architects to adopt green building techniques that contribute to a more sustainable future. GRIHA's holistic approach makes it a pivotal tool in India's efforts to create eco-friendly and energy-efficient habitats

2. WHAT IS GRIHA?
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)

3. 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.
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'
OBJECTIVES OF GRIHA

4. WHY CHOOSE GRIHA?
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.

5. INDIGENOUS RATING SYSTEM: THE SYSTEM ACKNOWLEDGES THE DIVERSE CLIMATIC CONDITIONS OF THE
COUNTRY WHICH BECOME THE UNDERLYING FACTOR FOR THE FORMULATION OF GRIHA RATING. THE RATING SYSTEM
AIMS AT PROVIDING INHERENT SOLUTIONS FOR THERMAL COMFORT WITHIN EACH REGION
ADOPTION OF HOLISTIC APPROACH TOWARDS SUSTAINABILITY: THE RATING SYSTEM WAS DEVELOPED WITH
THE INTENT TO PROMOTE SUSTAINABILITY BY NOT JUST UNDERLINING THE ENVIRONMENTAL ASPECTS BUT
ALSO FOCUSING ON THE SOCIAL AND ECONOMIC ASPECTS AS WELL
PROCESS DRIVEN AND PERFORMANCE ORIENTED: EVERY STAGE OF CONSTRUCTION, STARTING FROM
DESIGN CONCEPTION TO EXECUTION, IS VITAL TO ACHIEVE SUSTAINABILITY. GRIHA TAKES INTO ACCOUNT
ALL THE STAGES, INCLUDING DESIGN, PROCUREMENT, AND IMPLEMENTATION TO AVOID DISRUPTION TO THE
ECOLOGICAL SYSTEM AND CONSTRUCT HIGH-PERFORMING SUSTAINABLE STRUCTURES.

INTEGRATED TEAM APPROACH: WITH THE AIM TO INTERACT WITH THE PROJECT TEAM AND GUIDE THEM
THROUGH THE RATING PROCESS, AN ORIENTATION WORKSHOP IS CONDUCTED BY GRIHA COUNCIL WHERE
REPRESENTATIVES FROM DIFFERENT DIVISIONS HANDLING THE PROJECT ARE PRESENT TO UNDERSTAND THEIR
ROLE IN MAKING THE PROJECT GRIHA COMPLIANT. (REFER TO RATING PROCESS)
SAILENT FEATURES OF GRIHA

6. FIVE 'R' PHILOSOPHY
Refuse: To blindly adopt international technologies,
products, etc. Especially in substitutes are available
trends, materials, areas where local substitues 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.

7. GRIHA RATING PROCESS

system ,criterias ,and addresses
queries
3.Due diligence I
Site visit shall be scheduled during
construction phase when the project is
carrying out above plinth level work such as
column and slab construction.
4. Due diligence II
The second site visit shall be conducted
to validate internal finishes, electrical,
plumbing, and mechanical components
installed during the construction phase.
5.Submission of documents
As the project is nearing completion, the
project proponent will upload the
documents for all criteria on the online
panel
6.Preliminary evaluation
Preliminary evaluation is carried out
by a team of professionals from GRIHA
Council and external evaluators, who
are experts in their respective fields
recognized by GRIHA Council.
ELIGIBILITY
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.

8. BUILT-UP AREA(SQ M) FEES FEE USD
TILL 10,000 SQM RS 3,74,000+GST 5500
FOR EVERY SQM ABOVE 10,000 RS 7.5/SQM+GST 0.2(20 CENT)/SQM
7.Final due diligence
The final site visit shall be conducted by the GRIHA Council
officials to verify the submitted documentation with on-site
implementation. The visit is done once the project is complete and
all equipment and systems are installed and commissioned.
8.Final evaluation
The GRIHA Council officials along with external evaluators shall
then evaluate the final round of submitted documentation and the
final site visit report in response to the preliminary evaluation. The
final rating is awarded based on the final evaluation and is valid up
to 5 years.
9.Additional due diligence Green awareness drive
The GRIHA Council conducts an additional due diligence
visit post the final rating, for green awareness and
education amongst project occupants.
10.Rating renewal
There are two ways in which the rating can be renewed and the
project gets to enjoy the perks of being called a rated building. This
can be done either by submitting an audit data report comprising
energy, water, and waste or by enrolling the project for GRIHA EB
rating to maintain its certification for the next cycle of 5 years.
