Hi Friends......!!!!! its about Energy Efficent Stuctures and their purposes and Advantages......!!!!!

2. *ENERGY EFFICIENT
STRUCTURES

3. The energy for life………..
Energy is essential to our daily lives.It heats our home
Fuel our transport and supplies electricity .At the moment
we use most of the energy come from our
fuels.Unfortunately there is limited supply of fossil fules in
the world we are using them up at a very fast rate.
Why we use energy efficient
structure !

4. Energy efficiency
Energy efficiency is "using less energy to provide the
same service".

5. Energy Efficient Structure
Energy Efficient Structures can be described as the structures that
involve the use of less energy intensive materials required for the
construction.

6. Natural Ventilation
Natural ventilation is the process of supplying and
removing air through an indoor space by natural means,
meaning without the use of a fan or other mechanical
system. It uses outdoor air flow caused by pressure
differences between the building and its surrounding to
provide ventilation and space cooling.

7. Importance
Natural ventilation is important because it can provide and move
fresh air without fans. For warm and hot climates, it can help meet
a building's cooling loads without using mechanical air conditioning
systems.

8. Wood can be cheaper material.
Wood is naturally beautiful.
Wood is naturally insulator.
Wood Structure !

9. Wood is durable.
Wood is structurally very strong.
Wood is fast and efficient to build.
Wood Structure !

10. Roofing is a profund effect on our whole structure because it
effects on our building maintiance .
An efficent total roofing system can lower the energy
required for our building structure by 30 percent or more.

11. If the house is exposed to the low altitude winter sun
should be glazing on the south side.
Masonary walls and concret floor can absorb energy
during the day and release it gradually during the
evening.

12. Otherwise additional measures will be required to avoid
overheating in summer and excessive heat loss at night and on
overcast days in winter.

13. Structure of our building should be in such a way that we use
maximum sun light instead of electricity applieances.
