A green city uses environmentally friendly processes throughout its lifecycle by employing renewable materials, recycling, and blending with the local environment. This reduces impacts on the environment while improving efficiency. Green cities are gaining importance due to their cost savings. However, current cities face problems like lack of eco-friendly construction, waste management, and renewable energy usage. Transitioning to green cities can provide health, environmental, and economic benefits like emissions reduction, resource conservation, and cost savings. This involves strategies like green building materials, renewable energy systems, water recycling, and waste management.

1. GREEN CITY

2.  WHAT IS GREEN CITY ????
 A green city is a city which possess
structure’s that uses processes that are
environmentally friendly and resource –
efficient throughout its life-cycle .
 This is done through the use of renewable
materials , internal recycling , biodegradable
construction materials and blending it with
local environment so as to reduce negative
impacts on the environment .

3.  They are extremely efficient when it
comes to gas , electricity and water
and will over all results in savings.
 The ‘Green city’ concept is gaining
importance in various countries,
including India.
 These are cities that ensure that
waste is minimized at every stage
during the construction and
operation of the building, resulting in
low costs, according to experts in the
technology.

4.  WHY IT IS REQUIRED ???
 The way the world has used
global natural resources in the
past has placed a tremendous
strain on the environment.
 Depleting our natural resources,
polluting the environment,
warming the earth, raising sea
levels, and endangering our
biodiversity.

5.  Climate change has become the
inevitable result of our past
actions.
 According to the United Nations,
cities consume two thirds of global
energy use.
 76% of the world’s energy-related
carbon dioxide (CO2) are also
emitted by cities through transport,
industry, and building and
construction related activities.

6.  Studies have shown that
buildings and construction
activities use 40% energy, 30%
mineral resources and 20% water
of the world’s resources.
 It also accounts for 40% CO2
emissions, 30% solid wastes and
20% water pollution in the world.

7. Problems in our city
NO USE OF ECO
FRIENDLY MATERIAL IN
CONSTRUCTION
PROCESSES.
NO RAIN WATER
HARVESTING METHODS
USED IN HOUSES.

8.  NO CONTROL ON DUMPING OF
HOUSEHOLD WASTE.
 It is a major source of pollution.
Indian cities alone generate more
than 100 million tons of solid
waste a year.
 Solid waste is routinely seen
along India's streets and shopping
plazas.
 Public places and sidewalks are
despoiled with filth and litter, rivers
and canals act as garbage
dumps.

9. MORE USE OF NON RENEWABLE
ENERGY
 India used 148.7 million tonnes coal
replacement worth of fuel wood and
biomass annually for domestic energy
use.
 Greenhouse gases emission of the
country is the third largest after china
and the united states.
 The world health organization, claim
300,000 to 400,000 people die of indoor
air pollution and carbon monoxide
poisoning in India .

10. NO PROPER PLANNING OF
CITIES
 Traffic congestion on good road
infrastructure is a daily reality of
India's urban centres.
 Slow speeds and idling vehicles
produce, per trip, 4 to 8 times more
pollutants and consume more carbon
footprint fuels, than free flowing
traffic.
 In cities like Bangalore, around 50%
of children suffer from asthma .

11. NO ADDOPTATION OF ECO
FRIENDLY PROCESSES.
• 100 million households in
India use such stoves
(chullahs) every day, 2–3
times a day.
• It is a major source of air
pollution in India, and
produces smoke and
numerous indoor air
pollutants at concentrations
5 times higher than coal.

15.  GREEN CITY PLANNING AND
MASSING
TRADITIONAL PLANNING
AND DESIGN APPROACH
INTEGRATED GREEN CITY
DESIGN APPROACH
 The focus is to reduce up-
front capital costs.
 Systems are considered in
isolation and often result in
over-designing / over-sizing.
 The project team aims towards
reducing long term operation and
maintenance costs by using
highly efficient systems.
 Total city performance is used to
assess how each system affects
one another to deliver the
optimum design.

16. MASSING OF CITY
 More windows and
ventilations towards south
west direction.
 20% window to wall ratio in
south ward direction.
 5-10% window to wall ratio in
other directions.
 Planning is done so as to
gain maximum sun light.

19. BUILDING ENVELOPE
 FLY ASH BRICKS ( FOR MASONARY )
1. Fly-ash bricks are eco friendly as it
manufacture from utilization of waste
products of coal or lignite based thermal
power plants.
2. It is three times stronger then the
conventional burnt clay bricks.
3. Efflorescence is negligible.
4. Fly-ash bricks is lighter than the
conventional clay bricks as it weight
around 3 to 3.2 kgs per bricks.

20. AERATED CONCRETE BLOCKS
( FOR MASONRY )
 AAC its light weight (20% of
the weight of concrete).
 Up to 80% of the volume of an
AAC block is air.
 It can carry loads of up to 8
Mpa.
 Highly thermally insulating
concrete-based material.

21. HOLLOW BLOCKS ( MASONARY)
• Fire resistant .
• Saves 30% of concrete.
• Provide thermal and sound
insulation.
• Economical.
• Environment friendly, fly ash
used as one of the raw
materials.
•Reduces cooling loads.

22. GEO POLYMER CEMENT
 Clinkers=30-40%
(Highest contribution in polluting
environment )
 Fly-ash = 25-35%
 (Thermal power plant waste .)
 Stone dust=40-50%
(dust from quarries )
 Air entraining agents =0.05%
 Gypsum= 3%

23.  RECYCLED CONTENT STEEL
AND ALUMINIUM

24. FSC CERTIFIED WOOD.

25.  UPVC DOORS AND WINDOW.

26. HIGH ALBEDO PAINTS.

27.  LOW–E–GLASSES

28.  INSULATIONS

29.  ROOF GARDENING
 Provides more positive
environment around
building.
 More garden area is
achieved .
 Provides thermal solutions
for below floor.

30.  HEATING VENTILATION AND
AIR CONDITIONING

31.  LIGHTING
 Reduces energy costs — uses at
least 75% less energy than
incandescent lighting, saving on
operating expenses.
 Reduces maintenance costs —
lasts 35 to 50 times longer than
incandescent lighting and about 2
to 5 times longer than fluorescent
lighting.
 Reduces cooling costs — LEDs
produce very little heat.

32. FIVE STAR RATED APPLIANCES
• Lower Utility Bills.
• Improved Quality and
Durability.
• Enhanced Performance

33. RENEWABLE ENERGY
SOLAR POWER FOR RESIDENTIAL
 2bhk = 3600rs/annually.
 3bhk = 8600rs/annually.
 5bhk = 8800rs/ annually.
 Show rooms =
23600rs/ annually .

34. SOLAR LIGHTS
SOLAR GARDEN LIGHTS SOLAR STREET LIGHT

35. SOLAR HEATER.
 Saves 21.37 kg of
L.P.G. annually.
 Permanent solution.
 large quantity of hot
water can be obtain.

36. BIO GASS PLANT
 Nitrous oxide (n2o) warms the
atmosphere 310 times more than
carbon dioxide and methane 21
times more than carbon dioxide.
 One cow can produce enough
manure in one day to generate 3
kilowatt hours of electricity. (I.E. 72
kv/ day )
 Only 2.4 kilowatt hours of electricity
are needed to power a single 100-
watt light bulb for one day.

37. WATER EFFICIENCY
ROOF TOP RAIN WATER
HAVEESTING USE OF PAVING BLOCKS

38. WATER SAVINGS
 For example, if roof area is 10 meters long and
20 m wide and the annual rainfall is 350
millimeters, rainwater available will be
 10 x 20 x .350 x 1000 = 70000 liters
 for a family of 5 persons, this amount of
water can provide a daily supply of 38 liters per
person per day (lpcd)
 70000 = 38 lpcd (approximately)
 5x 365

39. PLANTS WITH LOW WATER
REQUIREMENTS.
KADVI MEHNDI CYCUS PANDA

40. SEWAGE TREATMENT PLANT
 Saves money by recycling a portion
of your wastewater .
 Ground water surface water source
is safe from pollution due to
treatment of waste water.
 Treated water is used for
vegetation.
 Air pollution is limited to treatment
plant.

41. SOLID WASTE MANAGEMENT
 Bio-degradable waste
should be collected
separately.
 Non bio-degradable
material should be
collected separately.
 Recyclable materials
should be sent for
recycling.

43. Conclusion
This way, we ensure that India
can enjoy both economic growth
and a good living environment
for ourselves, and for the future
generations.
