3. Housing Demand
 The report of Suresh Tendulkar committee said that 82% of deprived of basic needs in the
country(2008).
 Due to drastic demographic increase the housing demand goes to the top nearly 35% of
Indians are living without shelter(2014).
 “More the People = More we need Cities/villages = More the Energy = it reflects More the
Impact”
 Our villages the traditional practices of constructions are getting vanishing and slowly the
contemporary buildings conquers everywhere – there everyone needs energy
Improper Survival Facilities
Unavailability of Living Standards
Development Without considering Energy saving vernacular Architecture

4. Urban and Rural Context of India
India the worlds fastest developing nation going to reach 50% of its
population in urban areas by 2030.
In India we possesses 5480 urban cities and 640 867 villages.
Due the rapid growth of urban cities there is a huge lag in considering the
quality of environments urban Living as well as rural villages.
All the urban cities of India Possess unhygienic slum environments and
villages are in need of basic amenities and infrastructure facilities.

5. Demography – In and Around - problems
 For about 2.9 million years the population growth rate remains constant but
from 1000 AD to till date the population hike to about 70%.
 In population India ranks number 2 in the list of countries by population.
 The population density in India is 386 people per Km2.
 India's population is equivalent to 17.5% of the total world population.
 27.8% of the population is urban India in which 40% lives without proper
houses. China and India consuming nearly 35% of world energy at present.

6. Society - Vernacular
The human society is the totality of an integrated set of people who lives in a
particular geographical location.
India is the land of diverse culture and heritage.
In its own India has 122 major languages and 1599 other languages.
The most structured integrated living from its historic background itself.
Our Indian civilization is one of the oldest civilizations of the world with wide
knowledge of building science in its own without disturbing environment.

7. Vernacular Architecture
“vernacular architecture is an area of architectural theory that studies the structures
made by empirical builders without the intervention of professional architects. There exist
many areas of non-professional architectural practice, from primitive shelter in distant
communities to urban adaptations of building types that are imported from one country to
another” – Paul Oliver

8. As Society we
• For Daily needs we are draining energy resources from the earth, almost 45% of world land mass is
already occupied and nearly above 50% of natural resources are completely drained by we people.
• Around 1.8 million species are identified so far in which more than 20% vanished and 15% is in danger.
• Construction Industry consumes 40% of total energy obtained.
• Not only consuming things from the earth we also do…..disturb…..pollute……destroy.
• Together we are juicing up the non renewable energy sources but our tradition possess a wide
knowledge of using renewable energy sources.

9. Pollution - Man Vs Environ
• Human Activities • 9/10% of Pollution is by Humans not by Nature • Nature
Volcanic eruption releases 8000 to
30000 metric tonnes Carbon per day and
per annum all around the world it is
calculated as 200 million metric tonnes.
This is Just One Simple Example
By using fossil fuels coal, crude oil and
Natural Gas we produced 26,8 Billion tonnes
by 2003. from that day to till date the carbon
Emission by fossil fuels increases in a rate of
60%.

10. Atmosphere – GHG emissions
We are keeping Heavier footprints over the Earth.
Things are happening which was not happened
before 600,000 years where organisms initiated the
beginning
Polar Ice Melting – Global Warming.

11. Issues such as climatic changes, environmental issues, pollution, Resource depletion, Genetic engineering, toxic and non
degradable wastes etc.,
Polar Ice melts
Global climatic changes
Acid Rain
Ozone Depletion
Earth core disturbances
Global Warming

13. Even Superhero's Can’t able to Save – Coz Reason IS..!

14. What will be the solution….?
Conserve energy To Save the Humanity

15. How to conserve energy in residences..?
Bio climatic Architecture
Light structure walls losses
heat instantly by allowing air
Circular structure buildings which exposes minimum towards external and
maximizes comfort level in hot dry climates of India
Loose roofing elements releases
hot air out – stack effect.
interconnected walls provide less
external impact from sun so it will
be suitable technique to reduce
heat into building.

16. • The term Bio climatic was first used by Victor Olgyay in 1963, Architect, Norway.
• The Architecture of vast Era’s & practices of our native scholar's who designed their own homes by understanding the native climate and
using the locally available materials to reflect the culture and heritage of their own.
• i.e., The process of being reconnected to the environment, during the design of buildings are called BIOCLIMATIC ARCHITECTURE.
Bioclimatic “ism” A movement of Climate responsive vernacular Architecture

17. • He stated that Climatic responsive building from the vernacular architecture is a perfect ideology of understanding climate
and natural components of earth to provide a comfortable indoor environment to the users.
• Even today Architects like Charles correa, Karan Grover and various earth architects practicing our vernacular techniques and
systems to achieve maximum comfortable indoor environments with less energy sources.

18. Need of the Project – Based on E-Demand
World Energy Council 2013 World Energy Resources: A Summary
?E
•Demand for energy will continue to grow for decades to come.
•Population increases and a growing rate of electrification will place huge requirements on
energy supplies.
E.!
•Global primary energy demand could increase by 50% by the middle of the century.
•At least 80% of this increase is expected to come from developing countries.
E..,
•The total primary energy demand of India is expected to increase by almost 150% by 2035
•Due to huge population and developments Energy demand in housing sector will be
200%.

19. In India the early Rig Veda clearly states the importance of five natural elements sky,
air, water, land and fire(Vaanam, kaatru, neer, nilam and neruppu). Also these
elements should be clearly analyzed before experimenting building.
Traditional building construction guideline vasthushastra also says the same.
“Scientifically it signifies, heating, cooling, ventilation, lighting and positioning of
building should be designed after considering these elements which will decrease
energy demand and support supplement source naturally”.

21. This is not about going back to traditional systems, and it is all about acquiring traditional practices and techniques to
modern buildings without satisfying current needs.
As Indians we posses our own rich and diverse range of high culture and heritage, for example our Indus valley civilization
cities Mohenjo-Daro and Harappa is the only settlements of that time which posses drainage network and it clearly defines
how systematic our traditional vernacular practices are….!
Our vernacular building construction system practices are starts with site considerations, soil & physical considerations,
climate considered, also considers techniques and materials available etc., it is collectively a perfect passive designing
system with climatic loads and energy consideration.
Scope and Limitations

22. Vernacular architecture have been developed and practiced by the people over generations & they are tried and tested
practices which sustains over the ravages of time using Locally available materials for their building erection which
responds climate without disturbing the environment.
Among other achievements in bioclimatology, Victor Olgyay developed a bioclimatic chart, which relates climatic data to
thermal comfort limits, to identify design strategies (OLGYAY, 1973).
The bioclimatic design is an approach that takes advantage of the climate through the right application of design
elements and building technology for energy saving as well as to ensure comfortable conditions into buildings (GOULART
and PITTA, 1994; ERG et al., 1999).
Scope and Limitations

23. So at present if we consider the same Bio climatic approach during the designing phase at initial we can able to save a high
energy potential. However,
In tradition we have regulated design solutions which satisfies their needs but now in modern practices we have a variety
in need and it is diversified.
There is a huge gap between designing buildings with bio climatic design approach and meanwhile our teaching of
Architecture is different when you practice it should be defined.
Bio climatic vernacular practices travelled a long journey to reach its maturity and it has to travel a long distance again to reach
architects and designers to practice this bioclimatic “ism”. - it’s a step to shorten the gap
