WHAT IS GREEN BUILDING RATING SYSTEM?
A rating system can be defined as a set of prerequisites and requirements
that a project team must fulfill in order to receive certification.
TYPES OF RATING SYSTEM
BREEAM- United Kingdom
LEED- United States
Green globes- Canada
Green star- Australia
BEAM- Hong Kong
GBCS- South Korea
GREEN BUILDING RATING SYSTEM
INTRODUCTION OF GRIHA
WHAT IS GRIHA?
Name: GRIHA is an acronym for Green Rating for Integrated Habitat
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)
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
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
Reduced destruction of natural areas, habitats, and
biodiversity, and reduced soil loss from erosion etc.
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
GRIHA is more suited to Indian climate. Also unlike LEED, it does not
promote usage of certain products like glass and air-conditioning
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,
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.
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.
Building project may register through the GRIHA website
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
GRIHA also provides one day training session for the registered projects
Overview of the green building design
Explanation of the rating system and criteria and points related to
Online access to the rating tool
Documentation process through use of online forms
1. Pre documentation stage: A team from ADaRSH along with the client’s
Integrated Design Team meet and determine the points being targeted by
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.
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
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.
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 area
GRIHA VERISON 2015
The latest version of GRIHA, GRIHA version 2015 (GRIHA V2015), was introduced
in January 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, and Innovation
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 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.
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
The points assigned to different criteria is based on survey conducted to
better reflect current resource priorities of India. The point split of various
sections is given below:
