6. GRIHA (Green Rating for Integrated Habitat Assessment)
GRIHA - Sanskrit word meaning – ‘Abode’
• An 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)
 NAME: GRIHA
 COUNTRY: INDIA
 ESTABLISHED: 2007

7. 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 levels
• Reduced destruction of natural areas, habitats, and biodiversity, and
reduced soil loss from erosion etc.

8. WHY CHOOSE GRIHA ?
• To lower operating costs
• For higher return on investment
• For greater tenant attraction
• For enhanced marketability
• For productivity benefits
• To reduce liability and risk
• To build healthier places to live and work
• For demonstration of Corporate Social Responsibility
• For future-proofed assets
• To gain competitive advantage

9. GRIHA PROCEDURE:
• GRIHA assesses a building out of 34 criteria
• Awards points on a scale of 100
• To qualify for GRIHA certification, a project must achieve at least 50 points
Eligibility
• Except for industrial complexes, all buildings – offices, retail malls, institutions,
hotels, hospitals, health-care facilities, residences, and multi-family high-rise
buildings – in the pre-design/design stage are eligible for certification under GRIHA
• ADaRSH (Association for Development and Research of Sustainable Habitats)
examine project documents to help project eligible for GRIHA rating and render
requisite assistance for registration

10. GRIHA PROCEDURE:
Registration Process :
• Building project may register through the GRIHA website
(http://www.grihaindia.org)
•For ease of adoption, registration should be completed at the onset of the project
cycle
•The registration process allows for access to essential information such as
o Application forms
o List of required submissions
o Score points
oThe weightage system and
o Online documentation

11. GRIHA (Green Rating for Integrated Habitat Assessment)
Evaluation Process :
1. Pre documentation stage –
A team from ADaRSH along with the client’s Integrated Design Team meet and
determine the points being targeted by the project
2. Post documentation stage –
• All necessary proof through documents for the points targeted under various
criteria is submitted
• Evaluation by third party regional evaluators
• To determine final rating that shall be awarded to the project

12. GRIHA (Green Rating for Integrated Habitat Assessment)
The preliminary evaluation is done by a team of experts from ADARSH
o Reviewing of the mandatory points and checking for compliance. The project is
rejected if mandatory criteria are not complied with
o Evaluation of the optional criteria and estimation of the total number of
achievable points
o All compliance documents are vetted through the appraisal process as outlined by
GRIHA
After the necessary documentation is uploaded, and systems commissioned on site, the
building is evaluated and rated in a three-tier process
• Evaluation report given to members of an evaluation committee : external
experts in building and landscape design, lighting and HVAC design, renewable
energy, water and waste management, and building materials
• The members independently review and award points, a provisional
GRIHA rating is awarded after evaluation of documents submitted
