3. Current scenario
• Sustainable development has become a global issue.
• Global climate change has become an increasingly serious
concern for the future
• Concern over the impacts of built environment on natural
environment, economy, health, and productivity
4. In our presentation we have consider
these things:
eco-friendly building

5. Building materials
The building material are responsible for about 20% of
CO2 gases emitted by a building during its life time .
we have considered these three materials:
• Fly ash bricks
• Fly ash concrete
• Low-E-Glass
6. Fly ash Bricks
Fly ash bricks are environment friendlyand cost saving
building products. It has also low energy consumption
and no emission of Green house
gases.
7. Bricks comparison
According to (ICE)
Normal bricks Per brick Fly Ash bricks
0.36 kg CO2 emission 0.05 kg
6.5 MJ Embodied energy 1.25 MJ
10 N/mm sq. Strength 15 N/mm sq.
4 days ( 1200 C ) Burning Overnight (100 C)
3.2 kg Weight 2.6 kg
-If we use fly ash bricks we can save Rs.1500 per cubic meter
8. Fly ash concrete
The concrete with
material as a partial
replacement of
cement with Fly ash.
It uses less energy in
its production &
produces less carbon
dioxide than normal
concrete.
9. Cost analysis of Normal concrete &
Fly ash concrete .
M20
Normal concrete Fly ash concrete
1m3 = Rs. 6000/ m3
[Source : ACC RMC plant
in front of lpu gate ]
1m3 = Rs. 6000
= 6000- (7 * 100) + (0.18
*100)
=Rs. 5318 / m3
[Note : if we replace 25% cement
with Fly ash ]
Save Rs. 6000-5318=682 per m3
10. • Less emission of CO2
• Reduction in shrink and creep.
• Heat of hydration is lower than normal conc.
• Better workability.
Advantage of Fly ash concrete .
11. Glass (Low-E-glass)
- Low-E-Glass is one of the most
popular and versatile building
materials used today for
constantly improving solar &
thermal performance.
12. one of the panes of glass is coated with Zinc, copper,
silver etc.
Advantages of coating
On hot summer days On cold winter nights
19. - It is one of the easiest method of recycle of kitchen waste
and to produce quality manure ( vermicompost).
Advantage of vermicopost.
- Improve the physiochemical and biological properties of
the soil.
- Useful in raising seedling and for crop production.
22. -If we use solar power and DC appliance we can directly
save 70% energy consumption .
-For ex. of (50 inches fan)
AC Fan DC fan
P = V X I
P= 220 X 0.36
P= 80 watts
P= V X I
P = 12 X 2.08
P= 25 watts
24. Suitability of Drip irrigation
• Desert areas, small and narrow areas .
• Place where runoff can be a problem.
• Steeper slope.
• watering vegetable gardens, fruit trees and flowers.
26. Advantage
• Preventing the runoff and evaporation.
• No problem of water logging.
• Leveling of field is not required.
• Feasible for the areas having scarcity of water.
27. Conclusion
To sum up, our project not only contributes towards a
sustainable construction and environment but it also brings lots
of benefits and advantages to building owners and users. Lower
development costs, lower operating costs, increased comforts,
healthier indoor environment quality, and enhanced durability
and less maintenance costs are hallmarks of a typical
Environment friendly building.
