 Indian Context
 Elements of a Sustainable Habitat
 Elements contributing to Sustainable Habitat
 Generalized Framework
 Energy Balance
 Necessity of Green Buildings
 Characteristics of Green Buildings
 Genesis of Rating System
 GRIHA Variants
 GRIHA and its Criterion

3. Indian context
 Urbanization
 Number of large cities to increase
 Energy security : fuel import dependency, coal
dependency increasing
 Energy shortages already, low per capita energy
consumption; environmental considerations
 Sustainable habitats
 Integrated planning esp. for cities
 Self-sufficient neighborhood

4. Elements of Sustainable Habitat
Optimal allocation of land
Built Environment
Buildings Surroundings
Efficient appliances and fixtures
Choice of materials
Location of Building
Smart Buildings (bldgs. as
generators of energy)
Transport systems
and infrastructure
Environmental management
- Water & waste
Energy security – renewable
sources and energy efficiency

5. Elements contributing to sustainable
habitat
 Density: It is the concentration of population, dwelling units, employment or
any other variable over a specific area which can be either gross or net
 Design: the street network which is pedestrian oriented rather than auto and
whose characteristics include side walk, inter connection with in the streets, number
of intersection, pedestrian crossing, street lighting
 Diversity: It is a measure of variety of land uses present in a given area on
the basis of floor area, employment and land area
 Distance to transit:the average of the shortest street routes from home
or work to the nearest rail stations and bus stops
 Destination accessibility: the ease with which one can access the
trip attraction to both local (market) and regional (jobs) destinations

12. GRIHA-Green Rating for Integrated Habitat
Assessment
Tool to facilitate design, construction, operation of a green
building ,and in turn ….measure “greenness” of a
building in India
What gets measured gets managed

16. KEY HIGHLIGHTS OF 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)

20. Can you 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
