Jeremie:

'''Embodied energy''' is defined as the available energy that was used in the work of making a product. Embodied energy is an accounting methodology which aims to find the sum total of the energy necessary for an entire product lifecycle. This lifecycle includes raw material extraction, transport, manufacture, assembly, installation, disassembly, deconstruction and/or decomposition.

Architecture in Auroville

2009-05-05T04:52:33Z

Jeremie:

== Introduction ==

Auroville wants to be a field of constant research
for architectural expressions,
manifesting a new spirit through new forms.
- The Mother -

The dream of building a new city for the future on a clean slate, with the purpose of promoting research and experimentation alongside integral development, has been attracting architects and students of architecture from all over the world ever since Auroville´s inception in 1968. Not having pre-defined by-laws or being bound by the conventions of human society has allowed a multitude of expressions to manifest in the course of Auroville´s development, as natural extensions of the quest for the new. Expression of core values.

As this website will amply demonstrate, experimentation in building done in Auroville covers various aspects of architecture, and includes building materials, building technology, eco-friendly architecture, climate responsive designs, integration with natural surroundings, cost-effective buildings, geomancy and geometry, as well as the design of spaces themselves, including experimenting with the lifestyle of the user. There has also been spillover into the design and management of building infrastructure, the building of integrated rainwater harvesting systems, domestic waste water treatment plants and the integration of renewable energy systems for energy demands.

One of the results of this very creative and intensive work was serious applied research, and the last decade has seen considerable advances in ferro-cement technology for roofs and interior fittings as well as compressed earth blocks for load bearing structures, some of which have won national design awards and significant grants-in-aid from agencies that support these innovations.

Roofing with reinforced concrete

2009-04-28T16:10:37Z

Jeremie:

[[Image:FlatSlab1.jpg|thumb|right|200px|Example of Flat Slab with RCC Beam]]

 

== Description ==

Additional reinforcement in terms of steel is added at that part of the beam, structurally where the sagging takes place. In the sense that normally across a beam or a slab, you have the reinforcements at the bottom. When we talk long spans, the slab might get weak and would result in small cracks. To avoid this the steel reinforcement of the slab doesn’t only spread across the bottom but also the top by bending the steel bars. This produces a resistant moment against the sagging point of the slab.

Roofing technologies in Auroville

2009-04-28T15:49:12Z

Jeremie:

[[Image:RoofTechs.jpg|right|800px]]

== Introduction ==

The following article is a documentation of varied roofing techniques that are practiced in Auroville. As there are a number of architects from different parts of the world practicing architecture in Auroville the one line in common that they all follow is so as to how things can be done in different ways. how to make a structure lighter ? how a structure could be more efficient in terms of the material we choose to build it with and its economy. Having a context like Auroville to start from in itself houses a land of opportunities. To start with , the soil , the climate and the local artisans are some of the factors. You will find here compilation of information over the topic with a wide variety of technique and skill .

A roof is defined as the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials, the local traditions of construction and wider concepts of architectural design practice, and may also be governed by local or national legislation. A verandah may be roofed with material that protects against sunlight but admits the other elements. The material of a roof may range from banana leaves, wheaten straw, terracotta tiles, aluminum sheeting and precast concrete. The durability of a roof is a matter of concern because the roof is often the least accessible part of a building for purposes of repair and renewal, while its damage or destruction can have serious effects. Some roofing materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outer layer. Newer systems include solar shingles which generate electricity as well as cover the roof. There are also solar systems available that generate hot water or hot air and which can also act as a roof covering. More complex systems may carry out all of these functions: generate electricity, recover thermal energy, and also act as a roof covering.

== The Aurovillian context ==

In Auroville from contextual and vernacular understandings, at times the most convenient and in some ways, cost effective roofing system is the pitched roof type. Although such an approach to the casual observer may appear easier to put together in terms of time for assembly, and acquisition of components, the design of the entire structure can actually prove to be rather complex as it involves the coming together of a multitude of parts, each with their own specific requirements and variability in terms of material potential. In many cases the architects who designed in Auroville adapted tried and tested methods, remolding them into innovative new manifestations of raditional techniques, giving rise to a wide range of variety in form, aesthetic and presence. Therefore to fully understand how the dynamics evolved, one should clearly outline definitions of terms used to describe elements of these roofs, so as to, at the least have a reference for the words in their original meaning, even though in these sometimes radical examples the words may not apply.

 

== Flat roofs ==

[[Image:FlatRoof.jpg|200x200px]][[Image:Flatroof1.jpg|200x200px]][[Image:Flatroof2.jpg|200x200px]][[Image:Flatroof6.jpg|200x200px]]

The flat roof that we most commonly know and perhaps use was found to be very differently used in ways that make it lighter, stronger and more durable.

The first thing that we could probably observe in a flat slab is its extensive use in concrete and steel that naturally results in an increase in the cost of the structure. Second is as a result of all its material being steel and concrete how heavy can the structure get ? And lastly how much of energy does it consume during the day considering how hot can concrete and steel get ?

The following techniques shows us how flat roof’s can be much lighter and at the same time more efficient and durable by using the same materials in a different way.

The Filler Slab technique for example was one such technique that we had come across in which was found to be experimented in different ways. The idea is that a filler is used to reduce the load of concrete that is actually used in the slab. Materials such as Hollow Terra Cotta blocks to inverted pots are used.

6. [[Roofing with kerala hourdi terra cotta blocks|Roofing with kerala hourdi terra cotta blocks]]

 

== Pitched roofing ==

The different ways in which a pitch can be achieved considering what material is being used plays an important role in how efficient the building can actually be. Few of the constraints that a pitch roof is normally put to test is its span which naturally tends to test the strength of the material which is used to achieve the pitch. Reinforced concrete rafters and wood are few of the materials that have been innovatively used in our study. The frame from which the pitch is made is finished with materials from terra cotta tiles to [[Thatch|thatch]]. Thatch is used in different ways as it proved to be at times in-efficient to the climatic and termite conditions. in some areas thatch was found merely to be palm leaves and else where was reinforced with straw bamboo strips and palm leaves. This was to provide a more cooler effect in its enclosures.

== Domed and Vaulted roofing ==

Domes and vaulted structures were constructed with materials such as bricks, steel and a locally termed material called “ guna tubes “. This is conical in shape made of terra cotta and is used to construct small span vaults. Another local term that we would come across is “ aachikal “ which is the local term of a small brick, which is used also in constructing vaults.

== Domed and Vaulted roofing ==

Domes and vaulted structures were constructed with materials such as bricks, steel and a locally termed material called “ guna tubes “. This is conical in shape made of terra cotta and is used to construct small span vaults. Another local term that we would come across is “ aachikal “ which is the local term of a small brick, which is used also in constructing vaults.

[[Image:FlatSlab1.jpg|thumb|right|200px|Example of Flat Slab with RCC Beam]]

 

== Description ==

Additional reinforcement in terms of steel is added at that part of the beam, structurally where the sagging takes place. In the sense that normally across a beam or a slab, you have the reinforcements at the bottom. When we talk long spans, the slab might get weak and would result in small cracks. To avoid this the steel reinforcement of the slab doesn’t only spread across the bottom but also the top by bending the steel bars. This produces a resistant moment against the sagging point of the slab.

== Introduction ==

The following article is a documentation of varied roofing techniques that are practiced in Auroville. As there are a number of architects from different parts of the world practicing architecture in Auroville the one line in common that they all follow is so as to how things can be done in different ways. how to make a structure lighter ? how a structure could be more efficient in terms of the material we choose to build it with and its economy. Having a context like Auroville to start from in itself houses a land of opportunities. To start with , the soil , the climate and the local artisans are some of the factors. You will find here compilation of information over the topic with a wide variety of technique and skill .

A roof is defined as the covering on the uppermost part of a building. A roof protects the building and its contents from the effects of weather. The characteristics of a roof are dependent upon the purpose of the building that it covers, the available roofing materials, the local traditions of construction and wider concepts of architectural design practice, and may also be governed by local or national legislation. A verandah may be roofed with material that protects against sunlight but admits the other elements. The material of a roof may range from banana leaves, wheaten straw, terracotta tiles, aluminum sheeting and precast concrete. The durability of a roof is a matter of concern because the roof is often the least accessible part of a building for purposes of repair and renewal, while its damage or destruction can have serious effects. Some roofing materials, particularly those of natural fibrous material, such as thatch, have excellent insulating properties. For those that do not, extra insulation is often installed under the outer layer. Newer systems include solar shingles which generate electricity as well as cover the roof. There are also solar systems available that generate hot water or hot air and which can also act as a roof covering. More complex systems may carry out all of these functions: generate electricity, recover thermal energy, and also act as a roof covering.

== The Aurovillian context ==

In Auroville from contextual and vernacular understandings, at times the most convenient and in some ways, cost effective roofing system is the pitched roof type. Although such an approach to the casual observer may appear easier to put together in terms of time for assembly, and acquisition of components, the design of the entire structure can actually prove to be rather complex as it involves the coming together of a multitude of parts, each with their own specific requirements and variability in terms of material potential. In many cases the architects who designed in Auroville adapted tried and tested methods, remolding them into innovative new manifestations of raditional techniques, giving rise to a wide range of variety in form, aesthetic and presence. Therefore to fully understand how the dynamics evolved, one should clearly outline definitions of terms used to describe elements of these roofs, so as to, at the least have a reference for the words in their original meaning, even though in these sometimes radical examples the words may not apply.

 

== Flat roofs ==

[[Image:FlatRoof.jpg|200x200px]][[Image:Flatroof1.jpg|200x200px]][[Image:Flatroof2.jpg|200x200px]][[Image:Flatroof6.jpg|200x200px]]

The flat roof that we most commonly know and perhaps use was found to be very differently used in ways that make it lighter, stronger and more durable.

The first thing that we could probably observe in a flat slab is its extensive use in concrete and steel that naturally results in an increase in the cost of the structure. Second is as a result of all its material being steel and concrete how heavy can the structure get ? And lastly how much of energy does it consume during the day considering how hot can concrete and steel get ?

The following techniques shows us how flat roof’s can be much lighter and at the same time more efficient and durable by using the same materials in a different way.

The Filler Slab technique for example was one such technique that we had come across in which was found to be experimented in different ways. The idea is that a filler is used to reduce the load of concrete that is actually used in the slab. Materials such as Hollow Terra Cotta blocks to inverted pots are used.

== Pitched roofing ==

The different ways in which a pitch can be achieved considering what material is being used plays an important role in how efficient the building can actually be. Few of the constraints that a pitch roof is normally put to test is its span which naturally tends to test the strength of the material which is used to achieve the pitch. Reinforced concrete rafters and wood are few of the materials that have been innovatively used in our study. The frame from which the pitch is made is finished with materials from terra cotta tiles to [[Thatch|thatch]]. Thatch is used in different ways as it proved to be at times in-efficient to the climatic and termite conditions. in some areas thatch was found merely to be palm leaves and else where was reinforced with straw bamboo strips and palm leaves. This was to provide a more cooler effect in its enclosures.

Roofing with traditional madras roofing technique

2009-04-28T13:52:57Z

Jeremie:

[[Image:Aachikaal2.jpg|thumb|right|200px|Example of Madras roofing]]

 

== Description ==

This is a traditional flooring technique found particularly practiced in south India. It involves the use of wood and “ aachikal “ ( a locally termed material which is a small brick )and lime plaster. Commonly used for small spans. Wooden beams are used to cover the span. Over this wooden beams are laid at intervals of less than 45cms from each other. The gaps between is filled with bricks on edge with lime plaster. Upon this “ aactchikal brick “is laid on edge across in diagonal fashion plastered with lime.

== Materials ==

*‘AACHIKAAL’ Brick
*Lime Plaster
*Wooden rafters
*Brick Jelly
*lime
*'Kaduka' Fruit/Jaggery etc

== Details and experiences ==

Roofing with pre-cast ‘t’ beams and tiles

2009-04-28T13:30:14Z

Jeremie:

[[Image:Flatroof8.jpg|thumb|right|200px|Example of Pre-cast T bean and tiles]]

 

== Description ==

This is a technique to provide a light roofing system with heat insulation using reinforced concrete and terra cotta hollow blocks.
Reinforced Pre Cast concrete ‘T’ beams are made to span across at intervals not more than 39cms from each other as an inverted ‘T’.
If the span is large, the series of ‘T’ beams will then rest on additional reinforced concrete beam for the span.
Between the ‘T’ beams are placed the hollow terra cotta blocks, which provide the heat insulation.
Over this steel reinforcements are carried out on which the flooring is done.

== Materials ==

*Concrete
*Steel
*Filler
*Terra Cotta Hollow Blocks

== Details and experiences ==

Drawing showing detailed section of the reinforced concrete “T“ beam with steel reinforcement and tile. The space between the “T” junction to the end of the beam upon which the steel reinforcements are laid is filled with a light weight material. This is sometimes used as a cavity in the floor or as a filler to provide heat insulation to the enclosure.

The flat roof that we most commonly know and perhaps use was found to be very differently used in ways that make it lighter, stronger and more durable.

The first thing that we could probably observe in a flat slab is its extensive use in concrete and steel that naturally results in an increase in the cost of the structure. Second is as a result of all its material being steel and concrete how heavy can the structure get ? And lastly how much of energy does it consume during the day considering how hot can concrete and steel get ?

The following techniques shows us how flat roof’s can be much lighter and at the same time more efficient and durable by using the same materials in a different way.

The Filler Slab technique for example was one such technique that we had come across in which was found to be experimented in different ways. The idea is that a filler is used to reduce the load of concrete that is actually used in the slab. Materials such as Hollow Terra Cotta blocks to inverted pots are used.

== Pitched roofing==

The different ways in which a pitch can be achieved considering what material is being used plays an important role in how efficient the building can actually be. Few of the constraints that a pitch roof is normally put to test is its span which naturally tends to test the strength of the material which is used to achieve the pitch. Reinforced concrete rafters and wood are few of the materials that have been innovatively used in our study. The frame from which the pitch is made is finished with materials from terra cotta tiles to thatch. Thatch is used in different ways as it proved to be at times in-efficient to the climatic and termite conditions. in some areas thatch was found merely to be palm leaves and else where was reinforced with straw bamboo strips and palm leaves. This was to provide a more cooler effect in its enclosures.

Domes and vaulted structures were constructed with materials such as bricks, steel and a locally termed material called “ guna tubes “.

== Introduction ==

Auroville wants to be a field of constant research
for architectural expressions,
manifesting a new spirit through new forms.
- The Mother -

 

The dream of building a new city for the future on a clean slate, with the purpose of promoting research and experimentation alongside integral development, has been attracting architects and students of architecture from all over the world ever since Auroville´s inception in 1968. Not having pre-defined by-laws or being bound by the conventions of human society has allowed a multitude of expressions to manifest in the course of Auroville´s development, as natural extensions of the quest for the new. Expression of core values.

As this website will amply demonstrate, experimentation in building done in Auroville covers various aspects of architecture, and includes building materials, building technology, eco-friendly architecture, climate responsive designs, integration with natural surroundings, cost-effective buildings, geomancy and geometry, as well as the design of spaces themselves, including experimenting with the lifestyle of the user. There has also been spillover into the design and management of building infrastructure, the building of integrated rainwater harvesting systems, domestic waste water treatment plants and the integration of renewable energy systems for energy demands.

One of the results of this very creative and intensive work was serious applied research, and the last decade has seen considerable advances in ferro-cement technology for roofs and interior fittings as well as compressed earth blocks for load bearing structures, some of which have won national design awards and significant grants-in-aid from agencies that support these innovations.

Sadhana Forest

2009-04-21T12:36:42Z

Jeremie:

==Introduction==
Sadhana Forest in the south west corner may seem quite a way from many parts of Auroville, but it is really worth a visit. This ambitious reafforestation project was founded in 2003 by Aviram and Yorit, who at that time had practically no knowledge of forestry, but in the light of what Auroville is about, human unity, constant learning, a place of renewal and innovation, adventure, they put their life's savings of $63000 (earned from their work as professionals in business and archtecture, respectively) into the land and buildings (sustainable).

More than 18,200 indigenous Tropical Dry Evergreen Forest trees have so far been planted on the 70 acres of severely eroded, infertile land. This has been done with the labour and love of volunteers, from every corner of our planet. The trees have an exceptionally high viability rate, because they are planted with care and attention by motivated people who understand the importance of their work.

There is an EcoFilm Club every Friday, when you have the opportunity to join the volunteers in a delicious (well, I think so) vegan meal and maybe learn something of their joys and travails in this great experiment. Sadhana Forest is vegan, partly for the reason that when animals are bred on a large scale for people to eat or milk, then, apart from the question of the animals' production of "greenhouse" gases, given the universal shortage of land, it is probable some biodiverse forest will have be destroyed to make way for a monoculture for grazing.

Volunteers pay 150 rupees per day, to cover the cost of meals, all vegan and as much as they can get organic, nothing for their accommodation and internet access. Living is very simple and is based on a consciousness of the connection between our environment and ourselves, a connection that determine the much of the quality of our lives.

Electricity is from solar or kinetic power sources, nothing from the Grid. If you have a minimum of 2 weeks, and think you might enjoy the challenge of living a very simple life, you are always welcome to come and work, and enjoy yourself in this unique environment. They are planning to get electric bicycles for the free use of volunteers.  The toilets are designed to turn human waste into excellent compost for trees.   The kitchen has a low-tech, highly efficient, wood-burning ''Rocket ''stove that burns about one fifth of the wood compared with local traditional stoves, cooks much more quickly and produces very little smoke and waste.  Check out their ingenious but simple method for drastically reducing wastage of water when washing hands. 

 

Yorit and Aviram are extraordinary people, who have taken on an enormous and ambitious project to create biodiversity, improve people's lives, create an opporunity to practise human unity. Their systems of water conservation, pits and bunding, lakes and dams, have raised the local watertable from 7 metres to 1 metre. They are compassionate, thoughtful people, well worth meeting, if you are spending any length of time in Auroville.

 

There is an increasingly popular EcoFilm Club held there every Friday, with a film followed by a vegan (ie nothing of animal origin) meal.  There is no charge for this.

Luminosity

2009-04-21T12:32:15Z

Jeremie:

LUMINOSITY – PROJECT OVERVIEW [[Image:LuminosityDetailsPlan.jpg|thumb]]

In this project we are aiming to explore a new living/working environment within the context of the Residential Zone, utilising a number of ideas which have come up in the dreamcatcher forum.

First amongst these is the concept of raising the residential areas off the ground, whilst dedicating the ground floor to offices, studios and common facilities. This will assure a high degree of privacy for all the residents, avoid the need to build fences and water-intensive gardens, and help nurture an Auroville that 'belongs to no-one in particular' since people are then free to walk wherever they choose.

[[Image:North facade Luminosity.jpg|thumb]]

Nadja has also been working with Bernard (a frequent visitor to Auroville and a feng-shui professional from Switzerland) and Jean-Francois from Pitchandikulam (who has been working since some time on the ley-lines of Auroville), to improve and enhance the energetic foundation of the project.

Combining the principles of 'voluntary simplicity' with the essence of 'A temple for living and working in', we aim to create simple, rich and beautiful spaces for a daily life in which the growth of consciousness is the main focus - the emphasis clearly being on quality not quantity. To this end the individual rooms are not especially vast but are [[Image:South facade night Luminosity.jpg|thumb]]spacious, the materials are not particularly luxurious but are both hard-wearing and beautiful, and the detailing is not just the product of aesthetic criteria but of a well-thought-out functionality with a 'low-maintenance' approach.

The acoustic, climatic and environmental aspects of the project have also been at the forefront of the decision-making process and have strongly influenced the design.

Acoustically, all the apartments are separated from each other and from the staircases by cavity walls built of dense fly-ash blocks, which not only helps to lower sound transmission but also provides ducts for the various pipes and cables. The staircases themselves are built as free-standing elements unconnected to the main walls, and the north side of the apartments (facing away from the green corridor) are equipped with vertical acoustic louvres which can be closed either in case of monsoon rain (which usually approaches from the north-east) or in case of noisy activities either inside or outside the space.

[[Image:A-labelled.jpg|thumb]][[Image:B-labelled.jpg|thumb]][[Image:C-labelled.jpg|thumb]]

Climatically, the building has been oriented to make the most of the natural breeze in the summer months, where full-height sliding doors of mesh and/or glass can be opened to maximise the wind. In the morning and the evening hours the cavity walls to the east and west also minimise heat transfer from the sun, and the main roof will have gardens which have similar insulating properties.

From the point of view of water conservation, each apartment has a metered hook-up to the main RZ water tank, and the chlorine in this water will be removed by carbon filters as it enters the building. All the waste-water will be fully treated and then be re-utilised for both flushing the toilets as well as watering the planters on the balconies on the south side of the building. We also wish to experiment with catching the rain-water in a surface-level aquifer. If this works according to plan this option could provide each resident with up to 100 litres of fresh water daily throughout the year.

Although a TNEB connection is foreseen for each space, there will also be the possibility of connecting to photovoltaic panels for electricity and thermal panels for hot water. Another option is to hook-up to one of three de-humidification systems which will be built above each staircase and which will provide relatively cheap, dry air through the cavity walls to each studio and apartment.

The roof itself is to be seen as an extension of the community - with the provision of laundry/drying areas and meeting spaces under the photovoltaic panels, and a roof garden at each end of the building. Both the roof gardens and the surrounding landscape will have a focus on TDEF (Tropical Dry Evergreen Forest) species, and finally there is even the idea to make a start with roof-top agriculture, by dedicating an area to grow enough [[spirulina|spirulina ]] for everyone in the building...

MATERIALS

‘AACHIKAAL’ Brick

Lime Plaster

Wooden rafters

This is a traditional flooring technique found particularly practiced in south India. It involves the use of wood and “ aachikal “ ( a locally termed material which is a small brick )and lime plaster. Commonly used for small spans. Wooden beams are used to cover the span. Over this wooden beams are laid at intervals of less than 45cms from each other. The gaps between is filled with bricks on edge with lime plaster. Upon this “ aactchikal brick “is laid on edge across in diagonal fashion plastered with lime.
