The development of the former building centre evolved in such a way that the Auroville Earth Institute came into existence in The Auroville Earth Institute is researching, developing, promoting and transferring earth-based technologies, which are cost and energy effective. These technologies are disseminated through training courses, seminars, workshops, manuals and documents. The Institute is also offering various services, and provides consultancy within and outside India.

Climate Analysis Describe the local climate Realization Community is located in Auroville, an international township in the southern Indian state of Tamil Nadu, close to the city of Pondicherry.
The town is located close to the sea, on a plateau. Significant reforestation efforts have created large swaths of forest throughout Auroville, which has significantly improved the micro-climate of the area during hot seasons. This allows passive ventilation strategies to be a very effective mode of cooling.
Design Approach Site integration The layout of the buildings was done to preserve as much of the pre-existing vegetation as possible while taking advantage of prevailing wind direction for natural ventilation. The natural slope of the site allowed for a reduction in excavation for the foundations. Building design Realization apartments are multi-storied constructions with stabilized earth.
The buildings were designed with earth a building material from foundations through roof: principally Stabilized Rammed Earth Foundations, Compressed Stabilized Earth Block CSEB for load-bearing walls, and CSEB vaulted roofing along with ferrocement channels to minimize the use of conventional roofing materials.
Apartments were planned in accordance with the space allocation recommendations for Auroville, making ideal use of small spaces. Double height spaces were planned in many of the apartments to improve ventilation and natural light, while staggered floor plans were optimized for the prevailing winds.
Document Special Feature Natural Lighting Windows, especially in double height spaces with proper orientation for natural lighting without excessive heat gain. Water efficiency Rainwater from the roof is channeled to an underground cistern.
This harvesting tank is cross-purposed as an earth cooling tunnel. Rainwater harvesting swales are incorporated into the landscape for maximum percolation rates and groundwater recharge, in a region where low water-table levels and salt water intrusion are chronic risks threatening access to potable water.
Insulation: Insulation on vaults for reduced interior heat gain. Shading: Overhangs, set-back facades on vaulted spandrel walls, and tiered, elevated garden spaces shade the building envelop to reduce thermal gain and increase thermal comfort during the warm season.
Additionally, vaulted floor systems have cavities and ventilators which ventilate rising interior heat to the facades of the spandrel walls. Cooling tunnel: An earth cooling tunnel cools exterior air through heat exchange by passing the air through ducts which run through the subsoil and underground rainwater harvesting tank.
Hygrothermal cooling: Stabilized earth additionally has a hygrothermal cooling effect, as the active clay particles cause an evaporative cooling effect within the wall when exterior temperatures rise.
Cost effective features Virtually all buildings systems are equally as cost-effective as they are low in environmental impact: A key feature of earthen construction is that - as a labour- intensive construction technique - a high percentage of construction cost is invested into local economies of production and construction, as opposed to imported industrial building materials. Eco-friendly features The most passive approach of this building system is construction which minimizes initial embodied energy.
Maximum use of raw soil already a zero to very low EE material , further excavated from the site, dramatically reduces the initial embodied energy and carbon footprint of the construction. Thus, circular ecology principles govern the overall technical design.
Auroville, a cidade do amanhecer
AVEI has worked in 36 countries to promote and disseminate knowledge in earth architecture, and has garnered fifteen awards for its work four international awards and eleven national awards. Since , the Auroville Earth Institute has educated more than 13, people from 88 countries in sustainable building technologies and land management practices. The activities of the institute include research and development of earthen technologies , training and education , publication and dissemination, and the following services offered within India and abroad: conferences , consultancy , architectural design and construction , heritage conservation , production of materials, and quality control testing. The mission of the Auroville Earth Institute is: To revive traditional skills, and to link ancestral and vernacular traditions of raw earth construction with the modern technologies of stabilised earth. To enable and empower people to build their own dwellings using earthen techniques. To develop cost effective technologies, affordable to all. To respect our Mother Earth, while using its natural resources to build a sustainable future.
Auroville Earth Institute
The Mother Auroville will be the place of an unending education. The Mother Auroville is a conscious community in South India, it was founded a place for research , education and developing deeper humanity. Sanskrit is one of the official languages of Auroville. In this place, children would be able to grow and develop integrally without losing contact with their souls; education would be given not for passing examinations or obtaining certificates and posts but to enrich existing faculties and bring forth new ones. In this place, titles and positions would be replaced by opportunities to serve and organise; the bodily needs of each one would be equally provided for, and intellectual, moral and spiritual superiority would be expressed in the general organisation not by an increase in the pleasures and powers of life but by increased duties and responsibilities.
