Auroville, City of dawn is located in state of Tamil Nadu, India, near Pondicherry in South India. .Auroville was founded as a project on experimental basis of the ‘Sri Arbindo Society’ on Wednesday 28 February 1968. The basic idea originated from Mirra Alfassa ‘The Mother ‘who was spiritually related to India.
Ma envisaged Auroville as an international township for 50,000 residents on the shape of a flower. Architect Roger Anger refined the planning and designed it in shape of Universe.He placed Matrimandir at the center of this city.
Mary Alfassa in her first message regarding the town stated that, "Auroville is meant to be a universal town where men and women of al countries are able to live in peace and progressive harmony, above all creeds, all politics and all nationalities”

This modular housing based in Belapur, New Mumbai, is designed by Ar. Charles Correa. This project, which was constructed in the 1980s, stands as a perfect example of affordable and high density housing, which is the need of the hour.
Baker studied architecture in Birmingham and graduated in 1937, aged 20, in a period of political unrest for Europe.During the Second World War, he served in the Friends Ambulance Unit in China and Burma.He worked as an architect for an international and interdenominational Mission dedicated to the care of those suffering from leprosy. He focused on converting or replacing asylums once used to house the ostracized sufferers of the disease - "lepers".He Used indigenous architecture and methods of these places as means to deal with his once daunting problems.

Sustainable architecture is architecture that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, and development space.
Sustainable architecture uses a conscious approach to energy and ecological conservation in the design of the built environment.
The idea of sustainability, or ecological design, is to ensure that our actions and decisions today do not inhibit the opportunities of future generations.
There is no denying the fact that human habitat is an essential part of a civil society but at the cost of nature.
The natural resources are limited and depleting very fast.
Global CO2 emission is growing at 1.3% per year.
Energy in all forms generated for use by man is continuously getting more expensive and becoming scarce in availability.
Thus we must enforce measures of sustainability and live in harmony with nature.

What is Passive Design?
Passive design is:
is based upon climate considerations
attempts to control comfort (heating and cooling) without consuming fuels
uses the orientation of the building to control heat gain and heat loss
uses the shape of the building (plan, section) to control air flow
uses materials to control heat
maximizes use of free solar energy for heating and lighting
maximizes use of free ventilation for cooling
uses shade (natural or architectural) to control heat gain
It attempts to use natural principles in order to substantially reduce dependence on fuel based technologies for heating, cooling and lighting the building.
Differentiating Passive vs. Active Design
Passive design results when a building is created and simply works “on its own”. The plan, section, materials selections and siting create a positive energy flow through the building and “save energy”.
Active design uses equipment to modify the state of the building, create energy and comfort; ie. Fans, pumps, etc.
Passive buildings require active users (to open and shut windows and blinds…)
Solar Transmission Through Glass:
When sun strikes the glass part of the solar radiation is transmitted through the glass and proceeds to heat up the interior space.
Part of the solar energy is reflected off of the glass. The amount is dependent on the angle of incidence.
Part of the solar energy is absorbed into the glass, then reradiated both inwards and outwards.
When looking to AVOID heat entering the building it is critical to prevent it from this initial transmission through the glass – as once the heat is in, it is IN.
Solar Transmission through Varying Types of Glass
Different types of glass will transmit solar radiation differently. Residential and commercial glass type selection will be quite different. Residential buildings in cold climates are looking to allow heat in to use it for passive gain. Commercial buildings (with lots of interior loads from computers and equipment to offset) are normally looking to avoid heat gain.
Clear glass allows the most heat transfer. There are very few iron oxide pigments in this type of glass to absorb the heat.
Heat absorbing glass has different ingredients that initially absorb the solar radiation into the glass material itself, then radiate the heat later (more inwards than outwards).
Reflective glasses are used on commercial buildings that wish to avoid heat. Much more of the solar energy is diverted from entering the building.
Solar Energy as a Function of Orientation
This chart demonstrates the variation in solar energy received on the different facades and roof of a building set at 42 degrees latitude.
A horizontal window (skylight) receives 4 to 5 times more solar radiation than south window on June 21.
East and West glazing collects almost 3 times the solar radiation of south window.
Here we can see how a simple roof overhang acts as a shading device on the south side of the building. North facing glazing will only receive diffuse light for the majority of the year, and so no shading devices are required. When we design our elevations to be solar responsive, this will mean having different facade treatments to respond to sun angles and the degree of exposure of the facade.

Types of Radiation
The rays of the sun that carry solar energy can reach the interiors of our buildings through two primary means.
Direct radiation is transmitted directly through the glass and carries with it the maximum heating benefit.
Radiation can be reflected into the building either by bouncing off of light coloured surfaces on the ground around the buildings (like sand, light coloured concrete or snow), or it can bounce off of light coloured mateirals on the adjacent buildings. This can include light coloured stuccos, precast concrete or reflective glazing.
Reflected light does not carry as much solar energy as some of the energy will have been absorbed into the initially struck surface.
Reflected light is very useful when considering lighting a building with natural light, also known as daylighting.
