A project on planning and development of a Green City with zero carbon footprint.

2. Abstract
• To us, a green city is a city that has the cleanest and most efficient energy,
transportation, and building infrastructure possible.
• A green city derives its energy from renewable sources like solar and wind, and
distributes that energy through efficient and reliable systems.
• A green city is made up of buildings that are energy efficient, conserve water, and reduce
waste. A green city is connected by clean and accessible public transportation networks
and is biking- and walking-friendly. A green city is a healthier, more affordable, and more
pleasant place to live.
• In this project, we are building a township or a city which consists of houses, malls, office
buildings, signal lights, schools, drainage facility and amusement park.
• The city will have a drainage system that collects water from every house and recycles it.
• Renewable resources like wind power can be used to generate electricity which in turn is
used to light the city signal lights, street lights etc.
• Recharge ponds can be constructed to recharge the ground water.
• Rain water harvesting can be done to collect water for household uses such as flushing,
washing, gardening etc.

8. CITY LAYOUT

9. Individual areas covered
• Residential enclave = 57 acres
• Office, mall and school = 70 acres
• Solar farm = 30 acres
• Cultivated land = 17 acres
• Golf course = 20 acres
• Water treatment plant = 15 acres
• Green area = 50 acres

10. ELECTRICAL ENERGY CONSERVATION
CONVENTIONAL CITY GREEN CITY
Yearly consumption :-
Residential enclave = 44809 MWh/year
Office area = 132581 MWh/year
Mall = 1516 MWh/year
Other = 80000 MWh/year
TOTAL CONSUMPTION = 260000 MWh/year
Average saving using occupancy sensors/
photo sensors and daylight harvesting sensors
= 25%
Average saving using solar water heaters = 5%
TOTAL SAVINGS = 30%
Annual Saving in = 30% of 260000 MWh
electricity = 78000 MWh/year

11. WATER CONSERVATION
CONVENTIONAL CITY GREEN CITY
Water demand per capita per day = 150 L
Water consumed by 19000 people
= 150 X 19000
= 2,850,000 L
Average water consumption per year
= 1040 million liters
Recycling 80% of water used
= 80% of 2850000 L
= 2280000 L
Therefore, average annual conservation
= 2280000 X 365
= 832 million liters
Rain water harvesting :
Total catchment area = 1032 m2
Rain water harvested
= (Avg. annual rainfall) X (Catchment area) X
(Conversion factor) X 1000
= 0.862 X 1032 X 0.9 X 1000
= 800625 liters

13. CONVENTIONAL CITY GREEN CITY
Using coal as resource :
Electricity produced = 260 million kWh/year
Carbon emissions due to coal
= 1070 gCO2/kWh
Total carbon emissions = 260 X 106 X 1070
= 2.78 X 1011 gCO2/year
Using gas as resource :
Carbon emissions due to gas
= 662 gCO2/kWh
Total carbon emissions = 260 X 106 X 662
= 1.72 X 1011 gCO2/year
Average emissions = 2.25 X 1011 gCO2/year
Using solar power as resource :
Electricity produced = 80 million kWh/year
Carbon emissions due to PV panels
= 35 gCO2/kWh
Total carbon emissions = 80M X 35
= 2.8 X 109 gCO2/year
Using wind as resource :
Electricity produced = 180 million kWh/year
Carbon emissions due to wind energy
= 29 gCO2/kWh
Total carbon emissions = 180M X 29
= 5.22 X 109 gCO2/year
Total carbon emissions = (2.8 + 5.22) X 109
= 8.02 X 109 gCO2/year
Percentage carbon emission reduced = 100 – ((8.02 X 109)/(2.25 X 1011) X 100)
= 96%

14. Construction Material
Water-based paints that have no volatile
organic compound, which harm human health
Reinforcing bars made of 100% recycled steel
• Green concrete that used ground
granulated blasted slag to replace cement,
resulting in a reduction of the concrete
carbon footprint by 30-40% of CO2

15. Renewable resources
The city is powered by a field of 30 acres with
53000 solar panels with additional panels on
roofs. There are no light switches or water taps
in the city; movement sensors control lighting
and water to cut electricity and water
consumption by 51 and 55 percent respectively.
The rest of the power demand will be fulfilled by
the electricity produced from the offshore wind
farm.

16. Water strategy
• Reduce consumption to 130
L/c/d
• Reduce water leakage to 3%
• Recycle 90% of grey water

17. Greywater
50% to 80% of residential waste
water comprises of greywater.
Greywater is all water from house
except from toilets and garbage
disposal.
Greywater comes from:
#Kitchen
#Shower
#Sink
#Washing machine

18. Current system:
combine
greywater and
blackwater
Treat using
membrane
bioreactor
(MBR) plant
Treated
sewage
effluent will
be used for
landscaping
Biosolids
resulting from
the treatment
reused for
compositing and
in any future
waste-to-energy
plant

19. 80% of water that is used is recycled

20. Water storage tank capacity
Water demand per capita per day = 150 L
Water consumed by 19000 people= 150 X 19000
= 2,850,000 L
Taking water tank capacity = 3,000,000 L
= 3,000 cum
Assuming three tanks of 1000 cum capacity
Assume depth of one tank = 8m
Area of one tank = 1000/8 = 125 sq. m
Therefore, Diameter of each tank = 12.6 m

22. GOAL
To become a leader in carbon reduction projects in the region

23. PV electricity generation

24. Solar Water Heaters Save Energy
Solar water heaters keep the standard of living high while keeping energy consumption
down. Solar water heaters use a combination of the sun’s heat and photovoltaic cells to
heat water. This example is produced by the German company Guersolar.

25. Waste management strategy
50% of materials recycled
33% waste-to-energy
17% composting

26. Carbon neutral

29. Personal Rapid Transit (PRT) system of 100% electric-
powered, automated vehicles has been in operation since
2010 with existing road and railways connecting to other
locations outside the city.
PRT vehicles are sized for individual or small group travel,
typically carrying no more than 3 to 6 passengers per
vehicle.
The PRT vehicles will travel at speeds up to 40km/h, with
the longest routes in the city taking around 10 minutes.
