3. BACKGROUND
WHAT IS GREEN BUILDING?
 A ‘green’ building is a building that, in its design, construction or operation,
reduces or eliminates negative impacts, and can create positive impacts, on
our climate and natural environment. Green buildings preserve precious
natural resources and improve our quality of life.
GOAL OF GREEN BUILDING
 To help to sustain the environment without disrupting the natural habitats
around it
 To promote a better planet earth, and a better place for us all to live
 Reduce trash, pollution and degradation of environment.
 Create a sound indoor environment for living and working purpose.

4. FEATURES WHICH CAN MAKE A BUILDING ‘GREEN’
 Efficient use of energy, water and other resources
 Use of renewable energy, such as solar energy
 Pollution and waste reduction measures, and the enabling of re-use and
recycling
 Good indoor environmental air quality
 Use of materials that are non-toxic, ethical and sustainable
 Creating resilient and flexible structures
 Consideration of the environment in design, construction and operation
 Consideration of the quality of life of occupants in design, construction
and operation
 A design that enables adaptation to a changing environment

5. BENEFITS OF GREEN BUILDING

GREEN BUILDING RATING SYSTEM

7. INTRODUCTION OF GRIHA
 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)

8. There are three primary Rating systems in India:
 GRIHA (Green Rating for Integrated Habitat Assessment)
Green Rating for Integrated Habitat Assessment (GRIHA) 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.

9. EVOLUTION OF GRIHA

11. OBJECTIVE 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.

12. 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.

13. FIVE ‘R’ PHILOSOPHY
 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.

14. GRIHA PROCEDURE
ELIGIBILITY
 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.
 ADaRSH (Association for Development and Research of Sustainable
Habitats), GRIHA secretariat helps evaluate whether the project is
eligible for rating or not.

15. GRIHA PROCEDURE
REGISTRATION PROCESS
 Building project may register through the GRIHA website
(http://www.grihaindia.org)
 The registration process allows access to essential information related
to rating such as:
1. Application forms
2. List of submissions
3. Score points
4. The weightage system
5. Online documentation

16. GRIHA PROCEDURE
GRIHA also provides one day training session for the registered projects
which includes:
 Overview of the green building design
 Explanation of the rating system and criteria and points related to
rating
 Online access to the rating tool
 Documentation process through use of online forms
 Evaluation process

17. GRIHA PROCEDURE
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 the final rating that shall be awarded to the project.

18. GRIHA PROCEDURE
After the necessary documentation is uploaded, and systems commissioned on
the site, the buildings are evaluated and rated in three-tier process.
The preliminary evaluation is done by a team of experts from ADaRSH.
 Reviewing of the mandatory points and checking for compliance. The
project is rejected if mandatory criteria are not complied with.
 Evaluation of the optional criteria and estimation of the total number of
achievable points.
 All compliance documents are examined through the appraisal process as
outlined by GRIHA.
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 document is submitted.

20. GRIHA RATING CRITERIA
Criteria and their weightage
 GRIHA is a performance-oriented system where points are earned for meeting the
design and performance intent of the criteria.
 Each criterion has certain points assigned to it. It means that a project demonstrating
compliance with a criterion would achieve the associated points.
 GRIHA is a 100-point system consisting of some core points
 Different levels of certification (one star to five stars) are awarded based on the
number of points earned. The minimum points required for certification are 25.

21. GRIHA RATING CRITERIA
EVALUATED IN DIFFERENT STAGES
 Pre-construction stage (intra- and inter-site issues)
 Building planning and construction stages (issues of resource conservation and
reduction in resource demand, resource utilization efficiency, resource recovery and
reuse, and provisions for occupant health and well being). The prime 4 resources
that are considered in this section are land, water, energy, air, and green cover.
 Building operation and maintenance stage (issues of operation and maintenance of
building systems and processes, monitoring and recording of consumption, and
occupant health and well being, and also issues that affect the global and local
environment).
