CHAPTER 1 : SUSTAINABILITY 1.1 WHAT IS SUSTAINABILITY? 1.2 ROOTS OF SUSTAINABILITY
1.1 WHAT IS SUSTANABILITY ? • "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs ” • This responsiveness of design outcome has evolved with time. • one can see its initial step from the time when human started building for shelter from climate.
1.2
ROOTS OF SUSTANABILITY ? AT INDIAN LEVEL :
•
in 1700 BCE, and by 1900 BCE a majority of cities in the Indus Valley civilization were abandoned.
• Reasons including : •
decline in trade, climate change
•
and a break down in the social structure of the city through overcrowding and outmigration.
AT GLOBAL LEVEL : • Rachel CarsoN Silent Spring in 1962. •
she assessed how DDT and other pesticides harmed wildlife—especially birds, whose springtime chorus she claimed was going to go mute.
CHAPTER 2 : ELEMENTS OF SUSTAINABILITY 2.1. COURTYARDS
2.1 •
COURTYARDS
Both of the words court and yard derive from the same root, meaning an enclosed space.
COURTYARD KNOWN AS BAHL IN HAVELI ARCHITECTURE
• A courtyard or court is a circumscribed area, often surrounded by a building or complex, that is open to the sky.
• component “Courtyard” is COURTYARD KNOWN AS NALUKETTU IN KERALA
considered so significant that it might play a role of sacrificial
2.1.1 PURPOSE OF COURTYARDS : •
Socio-Cultural Aspects: The chowk served as the
Centre for various ceremonies and the rituals. The tulsi plant was placed here and worshipped daily to bring prosperity to the house.
• Security and Privacy: The chowk, at times, separated areas for men and women, and provided them with privacy. • Climate: The courtyard served as a micro-climate modifier. • Different Activities At Different Times: The use of the court in
2.2. WIND TOWERS
2.2
WHAT ARE WIND TOWERS
• The wind catcher's effectiveness had led to its routine use as a refrigerating device in Persian architecture. Many traditional water reservoirs (ab anbars) are built with wind catchers that are capable of storing water at
• A wind tower (wind catcher) is a traditional Persian architectural element to create natural ventilation in buildings.. The devices were used in ancient Egyptian archi tecture .
.2.1
WIND TOWER IN HYDERABAD : •
founded in 1768 by ghulam shah. They used a very simple form of ventilation, triangular structure, almost like chimneys are on top of the homes and are used to funnel cool breezes in.
• •
• •
IN SUMMER: the residents would open the shutter before sunset at 5:00 pm and close the shutter the next day around 11:00 am. In the summer the wind comes from the southwest. IN WINTER: they do the opposite, they opened the shutter around 11am and
.2.2
WIND TOWER IN ORCHA, M.P :
• In the center of Orchha town and walking past Phool Bagh, are the windcatching tall towers popularly called Sawan Bhadon. Legend states that these tall towers were erected in memory of two prince of Orchha.
• The Sawan Bhadon towers, which one can see on the right are actually air shafts, which captured the prevailing wind
• There is an resourceful system of water ventilation connecting the underground palace with Chandan Katora. •
These cooling towers, came to Orchha from their origin in

2.3. STEPWELLS
WHAT ARE STEPWELLS ?
• Stepwells are wells or ponds in which the water is reached by descending a set of steps. Stepwells are examples of the storage and irrigation tanks to cope with seasonal fluctuations in water availability. • Stepwells also served as a place for social gatherings and religious ceremonies. •
Stepwells usually consist of two parts: a vertical shaft from which water is drawn and the surrounding inclined subterranean passageways, chambers and steps which provide access to the well.
• The earliest forms of step well and reservoir were built in India in places
2.3.1
AGRASEN KI BAOLI :
• It is a 60-meter long and 15meter wide historical step well on Hailey 2.3. STEPWELLS
Road near Connaught Place, Jantar Mantar in New Delhi, India.
•
This Baoli, with 108 steps, is among a few of its kind in Delhi. The visible parts of this historical step well consist of three levels.
• Each level is lined with

PEARL ACADEMY OF FASHION
• : The Pearl Academy of Fashion is located in a typical hot, dry, desert type climate on the outskirts of Jaipur
2.3. STEPWELLS
•
The architecture of the academy ADAPTED passive cooling strategies such as open courtyards, water body, a step-well or baoli and jaalis .
•
The only way by which this figure could be achieved was by deploying passive and low energy strategies amongst other cost saving strategies such as the use of local materials, techniques etc. The resultant
2.4. COOL ROOFS
2.4 WHAT ARE COOL ROOFS ? •
A cool roof is one that has been designed to reflect more sunlight and absorb less heat than a standard roof cool roofs can be made of a highly reflective type of paint, a sheet covering, or highly reflective tiles or shingles
•
The first record of green roofing appeared four thousand years ago in the Hanging Gardens of Babylon, ,
•
the Babylonians installed stone terraces with gardens atop their buildings, fitting

2.5. RAIN WATER HARVESTING
2.5
WHAT IS RAIN WATER HARVESTING ? •
Rain water harvesting (RWH) is a technique of collection and storage of rainwater into natural.
•
One method of rainwater harvesting
REASONS FOR RWH :
is rooftop harvesting.
•
Rainwater harvesting will improve water supply, food production, and ultimately food security.
•
Since rainwater harvesting leads to water supply which leads to food security, this will greatly contribute to income generation.
With rooftop harvesting, most any surface — tiles, metal sheets, plastics, can be used to intercept the flow of rainwater
2.5.1 HISTORY OF RAIN WATER HARVESTING :
•
Burhanpur needed a lot of water. It was an important trade centre and was strategically located. In 1615 AD, the local ruler Abdul Rahim Khan invited a Persian geologist, Tabkutul Arz, to investigate the recharge valley in the Tapti plains. Arz did his groundwork, and devised a system.
•
The Burhanpur scheme consists of bhandaras or storage tanks, which collect groundwater from the underground springs flowing from the adjacent Satpura hills towards the Tapti. The groundwater is intercepted at four places northwest of Burhanpur,
CONCLUSION :
Sustainability is the only way by which we can pass our resources to the upcoming generations. It will help us to combat with the various climatic changes happening around us . Re visiting our roots is the option to a better and eco friendly environment. Sustainability helps us to march towards a better world causing minimum damage to the environment. It keeps a balance between man and environment. It will help the local communities and will avoid their relocation and displacement.
