ACRONYM FOR GREEN RATING FOR INTEGRATED HABITAT ASSESSMENT

2. GREEN BUILDING RATING SYSTEM IN INDIA :
There are currently two rating system being used:
• LEED (Leadership in energy and environmental design)
• GRIHA (Green Rating for Integrated Habitat Assessment).
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 .
• GRIHA MEANING:GRIHA is a Sanskrit word meaning ‘Abode’. GRIHA promotes passive techniques to
reduce energy cost while keeping the optimum thermal comfort inside the build environment.
• WHAT DOES GRIHA DO ?
 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.

3.  GRIHA is also focusing on promoting energy efficiency in existing buildings in urban areas which
will in return reduce energy demand.
SETTING UP OF GREEN BUILDING RATING (GRIHA)

4. Variants of GRIHA
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 RATING SYSTEM:
• Point system with differential weight age on various Criteria
50-60
61-70
71-80
81-90
91-100
KEY POINTS ABOUT GRIHA:
• Sets out guidelines for design, construction and operation.
•Combination of qualitative and quantitative criteria.
•Sets performances benchmarks for key resources like, energy and water.
•Facilitates integration of traditional knowledge on architecture with present day technology.
•Integrates all relevant Indian codes and standards(e.g National building code 2005, Energy Conservation
Building Code 2007, IS codes).
•Is in complete alignment with government policies and programs (e.g Environmental clearance by the
MoEF).

8. HOW TO DESIGN A GREEN BUILDING?
1.By adopting the integrated design approach such that the client, architect, engineers, and consultants
design the building in a coordinated manner with a common goal – sustainability.
2.By following regional development plans (such as the UDPFI guidelines, master plans) and local building
by-laws
3.By following India’s national codes and standards
4.By optimizing site conditions (trees, water bodies, wind-flow, orientation, etc.) and harnessing them to
cater to the thermal / visual comfort requirements of the building
5.By adopting sound architectural practices and taking examples from India’s traditional architecture
6.By adopting locally available construction materials and giving impetus to local arts, crafts, architecture
and artisans
7.By designing precisely-sized energy systems and not basing them on broad thumb-rules
8.By reducing the resource consumption of the building and its inhabitants so that the waste generating
there-from is reduced
9.By adopting energy efficient technologies (EETs) and equipment.
10.By adopting renewable energy technology (RETs) applications to reduce the demand on conventional
energy
