The document discusses energy conservation through earth sheltering techniques in building construction. It outlines that buildings currently consume one-third of India's total electricity, mainly for lighting, air conditioning, fans and refrigerators. Earth sheltering, by building structures partially or fully underground, can significantly reduce energy needs for heating and cooling. Some benefits include lower costs, requiring less building materials, and creating a more stable indoor climate. While there are some challenges like higher initial costs and ensuring proper ventilation, overall earth sheltering is an effective way to build green structures that conserve substantial amounts of energy.

2. WHAT IS ENERGY CONSERVATION ?
WHY CONSERVE ENERGY?
 ENERGY CONSERVATION IS THE PRACTICE
OF DECREASING THE QUANTITY OF ENERGY
USED AND WASTED .
 IT MAY BE ACHIEVED THROUGH
EFFICIECIENT AND REDUCED CONSUMPTION
OF ENERGY SERVIES.
 ENERGY CONSERVATION WIL RESULT IN
INCREASE OF FINANCIAL
CAPITAL,ENVIRONMENTAL VALUE,NATIONAL
SEQURITY AND HUMAN COMFORT

3. INDIAN SCENERIO OF ENERGY UTILIZA
 The buildings in India consumes one-
third of the country’s total electricity.
 According to BEE, lighting and air-
conditioning use 80 per cent of the
energy in commercial buildings, while
fans and refrigerators guzzle maximum
energy in residential buildings.
 The lifestyle of residents of cities have
changed the electric appliance market.
 The National Habitat Standard Mission
states that building energy consumption
has increased from 14 per cent in 1970
to 33 per cent in 2004-05.

4. OBJECTIVES OF PRESENT STUDY :
 TO UNDERSTAND THE EXISTING GAP BETWEEN BUILDING
PERFORMANCE AND ENERGY CONSERVATION .
 TO STUDY THE BENEFITS OF EARTH SHELTERING TECHNOLOGY
IN BUILDING CONSTRUCTION .
 TO COMMEND FUTURE CONSTRUCCTION TO TARGET AND HARVEST
SAVING POTENTIALS .

5. EARTH SHELTHERED HOUSING :
EARTH SHELTERED
BUILDING IS
A CONCEPT IN WHICH THE
BUILDING
IS PLACED PARTIALLY
BELOW THE
GROUND SURFACE AND THE
EARTH
THUS EXCAVATED BUILDING
IS USED

6. HISTORY OF EARTH SHELTERING HOUSES
 FROM PRE-HISTORIC TIMES TO THE PRESENT, HUMANS HAVE OFTEN TURNED TO EARTH
FOR PROTECTION AGAINST CLIMATIC EXTREMES AND DANGERS.
 IN AMERICAN MIDWEST, COLD HOUSES AND DUGOUTS WERE ALSO BUILT IN THE 1800’s
IN RESPONSE TO SEVERE HEAT AND COLD.
 THESE HOUSES ARE BUILT BELOW GROUND TO PROTECT THE INHABITANTS FROM THE
EXTREMES OF DAYTIME HEAT AND NIGHT TIME COLD.

7. TECHNOLOGY ADOPTED IN EARTH SHELTERING
 EARTH BERMING CONSTRUCTION
 IN HILL CONSTRUCTION
 UNDERGROUND RECESSED
CONSTRUCTION

8. IMPORTANT CONSIDERATION AND
CONSTRUCTION MATERIALS
 SITE INVESTIGATION
 CONCRETE
 PRE CAST CONCRETE PANNEL
 WOOD
 STEEL
 WATERPROOFING
 INSULATION

9. HOW ARE THEY BUILT ?
 FIND A LOCATION
 DIG OUT A HOLE FOR SIZE OF A HOUSE
 LAY DOWN A FOUNDATION
 CONSTRUCT ROOMS USING REBAR
 REBAR COVERED IN STEEL MESH
 STEEL MESH IS COVERED IN SPRAY CONCRETE
 THE ROOF IS COVERED IN WATERPROOFING THEN INSULATION
 FINALLY IT IS COVERED WITH SOIL

10. ADVANTAGES OF EARTH SHELTERED HOUS
 SAVES MONEY BY SPENDING LESS ON HEATING AND COOLING
BILLS
 LESS INVESTMENT ON FOUNDATION
 LESS BUILDING MATERIAL
 AESTHETICALLY PLEASING
 WARM IN WINTER,COOL IN SUMMER
 BUILT IN GREEN ENVIRONMENT SO ECOLOGICALLY SOUND
 FIRE RETARDART

11. CHALLENGES TO EARTH SHELTERED
HOUSE
 COSTS 20% EXTRA FROM CONVENTIONAL HOUSE
 DEPENDING ON TYPES OF EARTH SHELTER IT MAY NOT HAVE
WINDOWS AND PROPER LIGHTING AND VENTILATION
 REQUIRED CONSTRUCTION AREA IS LARGER
 SEEPAGE 0F WATER AND PENETRATION OF ROOTS

12. GREEN MAGIC
HOMES  PRE FABRICATED

 GIVES PROPER

 30% COST

CONVENTIONAL
HOUSE
 EASY TO

13. CONCEPT OF GREEN ROOFS:
 A GREEN ROOF OR LIVING ROOF IS A ROOF OF BUILDING
THAT IS PARTIALLY OR COMPLETELY COVERED WITH
VEGETATION AND GREEN MEDIUM , PLANTED OVER A
WATER-PROOFING MEMBRANE.
 IT MAY ALSO INCLUDE ADDITIONAL LAYERS SUCH AS ROOT
BARRIER AND DRAINAGE SYSTEM
 CONTAINER GARDENS ON ROOFS, WHERE PLANTS ARE
MAINTAINED IN POTS , ARE NOT GENERALLY CONSIDERED
TO BE TRUE GREEN ROOFS ,ALTHOUGH THIS IS DEBATED .
 ROOFTOP PONDS ARE ANOTHER FORM OF GREEN ROOFS
WHICH ARE USED TO TREAT GREY WATER.

14. CASE STUDY : BITS PILANI - RAJASTHA
Birla Institute of Technology & Science (BITS) Birla Institute of
Technology & Science (BITS) is an institutional building located in
Pilani. (Rajasthan). Recently it has new construction of Academic
Blocks, based on Earth Sheltering building concept. After working
on number of design options, Architect come up with a solution of
“Earth sheltered building” with following advantages.
To be able to go two stories below the ground, without obstructing
the view of temple from clock tower. The complete terrace of the
“new academic construction” is available to us for future use. The
challenges of “Daylight & Ventilation “are taken care by berming of
land on either side, at some distance from the building. Storm
water & toilet waste water is managed with open drains on either
sides of the buildings and water is collected in big sumps from
where it is pumped out at regular intervals.
