2. WHAT IS GREEN
BUILDING????

6. WHAT IS GREEN BUILDING?
 Green building refers to both a structure
and the using of processes that are
environmentally responsible and resource-
efficient throughout building's life-cycle:
from siting to design, construction,
operation, maintenance, renovation, and
demolition.
 Green building design involves finding the
balance between homebuilding and the
sustainable environment.

7. WHY GREEN BUILDING?
 World wide , building sector and it’s related
activities consumes:
 40% of energy
 25% of woods
 15% of water
 40% of raw material
 39% of CO2 emission (in USA)
 It also contribute to 40% of the waste send
to landfill

8. WHY GREEN BUILDING?
 A green building uses less energy, water
and other natural resources creates less
waste and green house gases and is
healthy for people living or working inside
as compared to a regular structure
 .According to TERI estimates, if all buildings
in Indian urban areas were made to adopt
green building concepts, India could save
more than 8,400 megawatts of power,
which is enough to light 550,000 homes a
year.

9. MAIN POINTS IN GREEN
CONCEPT
 Sustainable site design
 Water quality and conservation
 Energy efficiency
 Indoor environmental quality
 Material and resources

10. SUSTAINABLE SITE DESIGN
“A site plan that has the least environmental
impact while still meeting the clients project
goals.”
Important points includes:
 Site layout
 Impervious surfaces
 Sustainable landscape design

11. Site layout:
 Energy saving of 20%+
 Elongate on East/West axis
 Maximise North & South exposure for day
lighting
 Minimize East & West facing windows

12.  Building Orientation Source: www.nachi.org/building-orientatio

13. Impervious surfaces:
 Limit ground water recharge
 Increases pollutant load
 Create heat island effect

15. Reduce impervious surfaces by :
 Pervious pavement
 Planting in and around parking area
 Green roof

16. Sustainable landscape design by:
 Preserve existing plants
 Landscape irrigation using water from
showers and sinks
 Soil management techniques, including
composting kitchen and yard wastes, to
maintain and enhance healthy soil that
supports a diversity of soil life

17. WATER QUALITY AND
CONSERVATION
 It can be carried out by:
 Rain water harvesting
 Reuse and recycling of water
 Use of modern water fixtures

18. Rain water harvesting:
 Direct use
 Indirect use

19. Reuse and Recycle of water:
 Grey water: The relative clean waste water
from baths , sinks , washing machine and
other kitchen appliances.
 These grey water , after proper treatment
can be reused for toilet flushing and
irrigation of plants

21.  Use of modern water fixtures reduce
wastage of water to a great extend

23. ENERGY EFFICIENCY
 The most important element of green
building is energy efficiency. Higher energy
efficiency reduce carbon emission.
 It can be achieved by following ways:

24.  Maximize the use of renewable energy like
solar energy , wind energy, geothermal
energy etc

25.  Roof top or pole mounted wind turbine:
 Cuts electricity bill
 Performance depends on type of turbine
and location

26.  Using all energy efficient appliances
 Use daylighting
 Using smart lighting
 Use led lightings

27. INDOOR ENIRONMENTAL
QUALITY
 Indoor Environmental Quality (IEQ)
encompasses the conditions inside a
building—air quality, lighting, thermal
conditions and their effects on occupants or
residents.

28. Air quality:
 Low Volatile Organic Compound (VOC)
paints
 Moisture resistant building material
 Materials and system that require only
simple, non toxic or low VOC methods of
cleaning should be used

29. Lighting:
 Daylighting: It uses natural daylight as a
substitute for electrical lighting.
 An effective daylighting strategy
appropriately illuminates the building space
without subjecting occupants to glare or
major variations in light levels, which can
impact comfort and productivity.
 Use tinted glass and doubly glazed glass
can beused

31. Stack ventilation:
The stack effect describes the passive
movement of air through a building resulting
from differences in vertical pressure
developed by thermal buoyancy. When air
inside a building is warmer than the outside
air, the warmer, the less dense air will rise.
Stack ventilation takes advantage of this
effect by constructing openings in the building
envelope high at a substantial height,
allowing the warm air to escapeSource: https://en.wikipedia.org/w

33. MATERIAL AND RESOURCE
EFFICIENCY
The points to be noted under this includes:
 Low energy and durable materials
 Low site impact- no destruction of trees,
retained site vegetation
 Use of flyash concrete
 Use of locally available materials

34. Eco cement:
 Eco-Cement is a brand name for a type of cement
which incorporates reactive magnesia or
magnesium oxide, another hydraulic cement such
as Portland cement, and optionally pozzolans and
industrial by-products.
 Ordinary Portland cement requires a kiln
temperature of around 1450 °C. The reactive
magnesia in Eco-Cement requires a lower kiln
temperature of 750 °C, which lowers the energy
requirements, and hence the use of fossil fuels an
emission of carbon dioxide (CO2).

35. RATING SYSTEM IN INDIA
Whether Green buildings are really green is
to be decided against the predefined rating
systems. There are three primary Rating
systems in India.

36. RATING SYSTEM IN INDIA
Whether Green buildings are really green is
to be decided against the predefined rating
systems. There are three primary Rating
systems in India:
 Green Rating for Integrated Habitat
Assessment (GRIHA)
 Indian Green Building Council (IGBC)
 Bureau of Energy Efficiency (BEE)

37. GRIHA
 GRIHA is India’s own rating system jointly
developed by TERI and the Ministry of New
and Renewable Energy, Government of
India.
 The process initiates with the online
submission of documents as per the
prescribed criteria followed by on site visit
and evaluation of the building by a team of
professionals and experts from GRIHA
Secretariat.
 GRIHA rating system consists of 34 criteria
categorized in four different sections. ( 1)
Site selection and site planning, (2)
Conservation and efficient utilization of

39. Indian Green Building Council
(IGBC)
 The Leadership in Energy & Environmental
Design (LEED) is the rating system
developed for certifying Green Buildings
 LEED is a framework for assessing building
performance against set criteria and
standard point of references.
 Confederation of Indian Industry (CII) formed
the Indian Green Building Council (IGBC) in
year 2001
 Indian Green Building Council (IGBC) has
licensed the LEED Green Building Standard
from the USGBC. IGBC facilitates Indian
green structures to become one of the green

41. Bureau of Energy Efficiency
(BEE)
 BEE developed its own rating system for
the buildings based on a 1 to 5 star scale.
More stars mean more energy efficiency.
 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.
 The Reserve Bank of India’s buildings in
Delhi and Bhubaneswar and many other
buildings have received BEE 5 star ratings.

44. CONCLUSION
 Indians were aware of Green Building concepts
from the beginning. Conventional homes with
baked red colour roof tiles and clay made walls
is a really good example of energy efficient
structures that are used to keep cool during
summers and warm during the winters. Most of
rural India is still attached to this building
technology with naturally available materials like
clay, wood, jute ropes, etc.


45. CONCLUSION
 In this rapidly changing
world, we should adopt the
technology that helps us to
save precious natural
resources. This would lead
us to true sustainable
development.
