 50% energy saving potential.
 Buildings were responsible for 7.85Gt
of all energy-related CO2 emissions
worldwide and these emissions are
expected to grow to 11Gt by 2030

 Green building also known as green construction
or sustainable building.
 Green building: It is the practice of increasing the
efficiency of buildings through better design,
construction, operation, and maintenance
 It reduces impacts on human health and environment.
‘’Green building technology should reach all''

9. Materials used for green building

Wool brick
Triple-Glazed Windows
 Solar tiles
Bamboo flooring.
Ecological concrete. (admixture, di
calcium silicate instead of cement).
Paper insulation panels.

 Structure design
efficiency
 Energy efficiency
 Water efficiency
 Materials efficiency
 Waste and toxic reduction Green building CII Godrej

13. 13
STRUCTURE DESIGN EFFICIENCY:
Design of the building have an important role in cost and
performance of the building throughout the life cycle.
It aims to minimize the environment impact.
ENERGY EFFICIENCY:
The layout of the construction can be strategized so
that natural light is a source for additional warmth.
Shading the roof with trees offers an eco-friendly
alternative to air conditioning

14. 14
WATER EFFICIENCY:
 To minimize water consumption
 Rain water which has been collected, used, purified and
reused.
MATERIAL EFFICIENCY:
 Materials which are used should be recycled
 Should generate surplus amount of energy.
Ex : Solar power panels for lightening and also a useful
energy source.
WASTE REDUCTION:
 In green buildings all materials and energy sources are
efficiently used so that it ensures reduced waste
generation.

17. Austin Energy Green Building
17
In 1990, the City of Austin
established the first green
building programme in the U.S
The Austin Energy Green Building
(AEGB) program encourages to
design and construct more
sustainable homes and buildings
by creating a rating system.

18. Energy Star
18
It’s an international standard for energy
efficient consumer products originated
in the United States.
 It was created in 1992 by
the Environmental Protection Agency
and the Department of Energy.
 Devices using energy star mark, such as
computers, kitchen appliances uses 20-
30% less energy.

19. 19
The U.S. Green Building
Council (USGBC), co-founded by Rick
Fedrizzi, Mike Italiano, and David
Gottfried in 1993.
 It’s a non-profit organization that
promotes sustainability in buildings
design, construction, and operation.
USGBC is best known for its
development of the Leadership in
Energy and Environmental
Design (LEED) green building rating
system.

20. Indian Green Building Council
20
 The Indian Green Building Council (IGBC), was
formed in the year 2001 by Confederation
Indian Industry (CII).
 The vision of the council is to bring a green
building movement in India and facilitate India
to become one of the global leaders in green
buildings by 2021.
 Today more than 1053 green buildings are
being constructed all over India, of which 810
green buildings are certified and fully
functional.

22. Leadership in Energy and Environmental
Design
22
Leadership in Energy and Environmental Design (LEED) is
one of the most popular green building certification
programs used worldwide.
Developed by the non-profit U.S. Green Building Council
(USGBC) it includes a set of rating systems for the
design, construction, operation, and maintenance of
green buildings, homes, and neighbourhoods.

23. 23
The Gold and Platinum rating of
David L. Lawrence Convention Center
in Pittsburgh is the first convention
center in the world to have such
certifications.
Abad Nucleus Mall, at Maradu,Kochi,
is India's first LEED certified gold-
rated green mall.

24. 24
 The Tower at PNC Plaza is
a skyscraper in Pittsburgh, Pennsylvania
 The tower is one of the greenest high-
riser ever built, and even exceeds the current
criteria for a LEED Platinum certified building
 Taipei 101, the tallest and
largest green building of
LEED Platinum certification
in the world since 2011

25. Green Rating for Integrated Habitat
Assessment
 GRIHA attempts to minimize a
building’s resource consumption, waste
generation, and overall ecological
impact to within certain nationally
acceptable limits / benchmarks.
 It evaluates the environmental
performance of a building holistically
over its entire life cycle and provides a
definitive standard for what
constitutes a ‘green building’

26. Merits Of Green Building
26
 Efficient Technologies
 Easier Maintenance
 Return On Investment
 Improved Indoor Air Quality
 Energy Efficiency
 Water Efficiency
 Waste Reduction
 Temperature Moderation
 Healthier Lifestyles and
Recreation
 Improved Health.

27. DEMERITS OF GREEN BUILDING
 High initial cost
 Unavailability of materials
 Need more time to construct
 Need skilled worker

28. CASE STUDY 1
28

29. Objective of the study
29
To study the LEED and GRIHA rating system and
compare both with regards to their assessment
methods; scopes, performance criteria and energy
rating scales.

30. MATERIAL AND METHODS
30
First they have compared between LEED and GRIHA rating
system.
Comparison was done based the categories by which they
provide rating.
GRIHA rating system uses an offline questionnaire- based
approach.
LEED is documentation intensive, more complex , time
consuming process.

34. CONCLUSION
 Both rating system are good enough to be used.
 Each system has certain strong and weak points.
 These two system are based on different
parameters hence there is a possibility that both
systems rate the same system differently.

36. Objective of the study
36
 To provide an overview of the LEED-India and GRIHA
programs and examine the spatial dynamics of projects
developed under LEED-India and GRIHA requirements.

37. MATERIAL AND METHODS
37
Data were collected from the Indian Green Building
Council (IGBC) on LEED-India projects and from the
Association for Development and Research of Sustainable
Habitats (ADaRSH) for GRIHA projects.
Data have been collected from all green projects that are
certified by one of the rating systems from the
respective organizations.
Each project was reviewed to determine its geographic
location (i.e. state or union territory) and type of project
(e.g. residential, commercial, industrial, etc.).

38. RESULTS
38
Green buildings include commercial office and industrial developments.

Kalam, the then President
of India on 14 July 2004.
 This building became
India’s first Platinum
rated green building in
the year 2004

53. CONCLUSION
 In 2003, India had only 20,000 square feet of green
building area but today India has 1.1 billion square feet
building area .
 India is the second largest producer of green space in the
world after USA (3 billion square (Moloney 2013a).
 The cost associated with planning and constructing green
buildings has also decreased.
 In the early 2000 s, a green building costs approximately
18% more to construct compared with a traditional
building in India , today the difference between the two
building types is only 5% more (Moloney 2013b). 53
