SITE:

Sharanam is a 5 acre land 10 km west of Pondicherry with a dual context. On one hand, we have the Ousteri Lake, spread across 2000 acres, considered as one of the most important wetlands not just of South India but of Asia, the most important freshwater lake in the Pondicherry region. An unforgettable spectacle, during the spring months when it becomes home to the Lotus and during the winter when it shelters more than 75 species of migratory birds coming from as far as Siberia.

 

On the other hand, just across the road, we have a 200 acre landscape irresponsibly ravaged away leaving behind an ecological disaster in the form of a huge illegal mud quarry. Sharanam, literally and metaphorically is poised between these two extremes, incredible natural beauty abundant with water, flowers, birds and butterflies on the one hand and on the other hand, a man-made disaster which can be prevented through responsible design. Sharanam has a telling message to convey.

Typical of India, isn't it ? Beauty and devastation co-existing side by side.


Parts of Sharanam were being used as the illegal mud quarry and looked like this mud quarry - completely barren with nothing other than a row of Palmyra trees.

When I first saw this in 2006, I said - "The abused land is the present reality and the Blooming lotus is the promise of what it can become."

 

CLIENT & BRIEF:

The client was an international NGO - Sri Aurobindo Society, a wing of the Sri Aurobindo Ashram, based in Pondicherry. They have over 400 centres and branches around the world and wanted an iconic project at their headquarters in Pondicherry for their various activities in the fields of Culture & Education for conducting workshops and seminars. The one line brief I received from Mr. Pradeep Narang and Mr. Vijay Poddar was that it had to be "inspirational space" which would match, if not surpass, the elegance of Golconde. (insert link here). They wanted a Space which could create a "paradigm shift" in the minds of the user to catalyse a positive change.

 

Sharanam was co-designed and built by Trupti Doshi during her tenure as Chief  Co-Architect of Sri Aurobindo Society.

 

PROJECT BRIEF:

The Project Brief included comprehensive institutional facilities - a large multipurpose hall to seat 500 people, Reception, Administrative offices, Meeting rooms, Computer rooms, a newspaper office, Community radio station, Stores, Kitchen, Dining and a toilet block.

THE CHALLENGE:

This project presented a three-fold challenge. It had to be

1. Ecologically resilient - It had to demonstrate the highest standards of Sustainable Design and Construction

2. Climatically responsive - at 12 degrees North latitude in an excessively hot and humid climate where summer temperatures cross the 40 degree C mark and relative humidity in the range of 80%. The most comfortable space in such a climate was a tree! Essentially, the question we were asking ourselves was : How to design a Building like a Tree?

3. Culturally relevant - without going back to the past. It had to integrate traditional wisdom but boldly spring into the future as a beacon of an inspirational possibility.

 

THE INSPIRATION:

Whilst I was talking to the client in the office, at home I was reading the poem 'Savitri' by poet Sri Aurobindo and my eyes chanced upon a rather beautiful and cryptic line where he says:

"All our earth starts from mud and ends in the sky." Many of us would have experienced that at moments, seemingly divergent things come to us and one has the answer to the other. I decided to make this line the main inspiration behind the project.


“All our Earth starts from mud and ends in sky”


THE SOLUTION:

A friend once told me:

"When you have 1 problem and 1 solution, the answer is Enterprise.

When you have 10 problems and 1 solution, the answer is Design!"

Sharanam is a telling example of such a Design.

 

DESIGN FEATURES:

BIOCLIMATIC & BIOPHILIC DESIGN PRINCIPLES:

 

1. NATURAL LIGHTING

To reduce the operational energy during the life cycle of the building and making it energy efficient, the design maximizes the use of daylight.


Design maximising use of Natural Sunshine

 

2. FUNNELS OF BREEZE

The building has been oriented such that it is perpendicular to the direction of the breeze. Plus columns and walls are designed to funnel the breeze into the building. The surrounding landscape is positioned to allow cool breeze to enter the building at a lower level while hot air escapes out at a higher level.

3. NATURAL COOLING

Design is aimed at creating thermal comfort through bioclimatic principles without using air conditioning. To make the campus climatically responsive, 12+ principles of natural cooling have been integrated. These include north-south orientation, funnelling breeze through angled columns, evaporative cooling through water bodies, cavity walls increasing thermal mass, vertical gardens and rooftop gardens.

Radiant cooling, a low energy active system for thermal comfort, uses cooled water circulating in pipes under the floor to give a comfortable temperature at a fraction of the cost.

4. NATURAL ACOUSTICS

To overcome the erratic power supply, the vaulted roof has been acoustically designed to ensure that speakers can be clearly heard by 300 people without using microphones.

5. NATURAL MATERIALS

The primary building material is unfired earth used as rammed earth in the foundations and compressed stabilised earth blocks in walls, columns and roof. This earth was procured from the rainwater reservoir on the same site ensuring zero transportation costs, minimal dependence on expensive and high energy use materials like steel and cement, minimum carbon footprint and low embodied energy.

6. ZERO WASTE TECHNOLOGY

The building encompasses zero waste principles and is entirely recyclable. The earthen vaulted roof was built with 9.5m wide free spanning arches, without any formwork. Through precise structural calculations, the thickness of the arched roof was brought down from 150 cm to a mere 9 cm at the keystone, thus reducing the need of several hundred bags of cement to merely 33 bags.

7. NATURAL LANDSCAPING

In terms of ecological landscaping, over 1000 native trees were planted to repair the soil and prevent erosion. This thick tree cover helped in creating a favourable local microclimate through indigenous landscaping. The entire campus has been designed around existing trees and the surrounding flora greatly enhance the indoor air quality.

MATERIALS & CONSTRUCTION TECHNOLOGIES

The building had to be modern, highly engineered and breath-taking with the most environment friendly building material.

 

Our choice was the very Earth on which the Building stands. Earth has been used in 2 major ways at Sharanam :

1. Rammed earth foundations

Foundations pits were precisely marked on the ground. The soil was neatly dug out, sieved, mixed with a pinch of cement and rammed back layer by layer.

No steel or concrete has been used in the foundation pits.

These foundations are only 3 feet deep, waist height. We were told by the structural engineers that they are rock hard and capable of taking a 7 storey building on it.

2. Compressed Stabilised Earth blocks - CSEBs made with local soil by training local villagers.

Soil is evenly sieved, mixed with a pinch of cement which acts as a stabiliser, and made into blocks, precise to half a millimeter.

Normal bricks in the market have a wet compressive strength of 35 kg/ sq.cm. At Sharanam, we were able to achieve 75, which is more than double the strength.

In terms of environmental cost, they are 1/10th. They are not fired. No carbon dioxide has been let out into the atmosphere. No topsoil has been used to make them. They are made from the earth on the site itself so no fuel has been burnt for transport.

We made bricks of 9 different sizes and types depending upon the use. Here, the idea was complete Optimisation. Hence we made different bricks for the pillars, wall and the roof.

3. The third main material used is Ferrocement which utilises minimum Steel & Cement.

SUSTAINABILITY FEATURES

1. CLOSING THE LOOPS

The first principle of Sustainable Design is "Closing the Loops". It is not a linear process like the old industrial age where you put raw material, labour and capital at one end, go through a linear process and get the finished product and waste at the other end.

It is a cyclical loop just like Nature, where processes are clustered ecologically - the waste of one process becomes the wealth of the next and there is no wastage.

Sharanam is a living example of this. The rainwater reservoir provided the soil for making the entire 5 acre campus out of unfired earth including the foundations, walls. columns and roof.

While the roof collected rainwater which went back into the reservoir. The loop of nature was complete.


Closing the Loops - Rainwater reservoir gave Soil to create the Buildings. The Buildings harvest rooftop rainwater which goes back into this reservoir.

 

2. CLIMATE & ENERGY

Due to the 12+ principles of Natural cooling used at Sharanam, the entire campus is able to operate comfortably without air conditioners. The Design has brought down the electricity bills to less than 25%.

3. WATER & WASTE

Not a single drop of water is allowed to leave the campus.

To ensure minimal water footprint, rooftop rainwater is harvested and recycled for secondary domestic purposes such as flushing and refilling pools in the landscaping.

Treated wastewater from the kitchen and washrooms is used in irrigation as a natural fertiliser for plants.All this ensures minimum dependence on groundwater.

CULTURALLY APPROPRIATENESS THROUGH FORM AND FINISHES

One the most characteristic features of Indian Architecture is the concept of

- Open to Sky Courtyards

- Semi open Verandahs

- An undulating Floor-plate to form built in benches (Thinnai in Tamil).

You will find variations of these 3 giant principles of design through the fabric of India in varying forms.

At Sharanam, these 3 form the key principles.

- The main building is flanked on both sides by 2 large courtyards. Both these courtyards keep the building remarkably cool and catch and redirect the breeze inside.


Courtyards at Sharanam keep the building remarkably cool


- The entire main building is a giant multipurpose pavilion which is a channel of breeze throughout the day. It provided effective shading against the Sun while still providing ample daylight for all activities.


Channel of Breeze


- The defining element of the Architecture at Sharanam is the large thinnai, built in a bench made of black granite. This one large masculine element is the counterbalance of the elegant feminine arched roof above. Both elements run through the length of the building and bind the stretch into a composite whole.

In terms of Wall Finishes,

- We used different compositions of earth and lime plasters to give a variety of finishes right from rough grit finish for outdoor plaster to silky smooth earth plaster finish for certain indoor walls.

Most of the buildings are exposed brickwork and hence use Pointing to strengthen the mortar joints.


Exposed Brickwork

 

Floor Finishes were created using:

- Pebbles (when we were sieving the soil for making the earth blocks, we got thousands of small beautiful pearl-like pebbles)- An ancient Kerala technique which uses Lime, Coconut husk, Hibiscus flowers and Kajal (the black soot used to decorate women's eyes)


Floor Finishes using pebbles (found from the local soil while making blocks) and lime flooring with oxide colours

  

INSPIRATION FULFILLED

I began the Design Exploration of Sharanam with the poetry line :

"All our earth starts from mud and ends in sky."

 

For an Architect, the roof is the expression of the Sky. At Sharanam, we built this Sky out of Earth - the very earth below your feet.

TESTIMONIALS

Sharanam has been recognised by the United Nations Env. Programme as a model for Sustainable Development in India.

It has attracted 20,000+ visitors so far including prestigious personalities of national and international repute.

 

Some responses are:

"A truly inspiring project beginning with the simplest local materials and skills yet achieving the highest sublime aspirations of craftsmanship and elegance. As well as being a highly skilled architect, imaginative inventor and passionate educator, Trupti is also an eloquent and generous communicator. A rare combination and a real gem to find." - Musician Paul Johnson, UK.

 

"When you are at Sharanam, you feel like you have been transported to a different place. Time and space operate at a different level. The vault above feels like the descent of the heavens while the earth structure feels like the earth pushing you upward towards the skies. Sharanam could easily be a place that is the gateway to another dimension. Truly a magical piece of artistic architecture and engineering." - Lavanya Premkumar, Tampa, Florida

 

"I was very impressed with the Building but more so with the  Architect - Trupti is a role model for Generation Next!" - Deepak Gadhia, Solar thermal man of India.

 

"The built-environment embodied many values for me - truthful, honesty, humbleness, dignity, simplicity." - Architect Kabir Vajpeyi, Delhi

 

"Role model for a new future building concept. Environment is part of the planning and building process. The process of developing and constructing is by itself a deep spiritual process. Building as an expression of consciousness, awareness and respect for the purpose of its use." - Hans Peter Krauss, Business Coach, Frieburg, Germany

 

"Trupti has designed this building with remarkable imagination and thoughtfulness. I was very impressed by the attention to the details at each step." - Sehdev Kumar, inspirational speaker, Canada.

 

"Being an architect by profession and one who is passionate about green buildings and sustainability, a human being highly attached to nature, I was mesmerized and thrilled to see a building so connected to and well merged with the lush green surroundings and something which had so much meaning in its existence. A structure which was brought into life by co-existing with nature throughout the process as well as after. The space is a role model by itself to the people who come to visit, a perfect example to this cliche said by architects, "A building should speak for itself". A musical note, a tune, an art, a movement, a meaning, a positive vibe all by itself. " - Architect Gayathri. V, Pondicherry.

 

"As a librarian and lover of knowledge, I loved how Trupti has integrated her whole knowledge of architecture into a building. It deserves to be called a true green building ! In every way, it connected me back to nature - the slit in the roof through which I could see the sky was a delight ! The water under this slit in the sky was a heightened delight ! I wish her all the blessings to create more buildings like this which bring humanity closer to themselves and more respectful of creation around them." - Hemal Bhuta, Chicago, USA

 

"The building lifted up my spirits ! Day in and out, I talk to people who are trying to make dumb buildings smart through use of air conditioners and here is a building which is Smart by Design ! I am amazed ! And I feel a renewed sense of hope and joy for the future of buildings and the world at large. In the wake of climate change, this is the need of the hour ! Thank you Trupti !" - Suhas Jadhav, Air Conditioning Specialist, Pune

 

"I am a teacher by profession and for the first time I learnt that a Building can also be a Teacher ! It taught me many things - qualities like Observation, for instance. I was observing minute details everywhere and every place has a distinct uniqueness. Every detail has been thought through. As they say : God lies in the details. Every word of this maxim is true at Sharanam ! Indeed God is in the details in this building !

The building is a delight for children ! So many special places for them to jump around ! In fact I felt as though the whole building was designed with children in mind. Even the stones inside the water pond felt as though a child come jump up and down on them. The stage and the red staircase leading to it, the many levels through which one is visually connected felt wonderful. The building was a Delight to the Senses ! I felt very hopeful about our children ! I would like to bring all my students to experience Sharanam. And also all Adults - Sharanam will bring out the child in them ! Thank you Trupti ! " - Rani, India

 

"For the very time I realised that even a building can give you peace and joy!" - Chinmay Vadnere, Serial Entrepreneur, Founder - Shoonya Designs, Nashik

 

"Trupti was our Chief co-architect at Sharanam. Her dedication, sincerity and approach towards her work and co-workers is extremely positive with leadership qualities." - Pradeep Narang, Chairman, Sri Aurobindo Society, Pondicherry

 

"Architect Trupti has created an arched ceiling of exquisite beauty. The Earth below me has become the Sky above me. When I was playing (the violin), "earth" was listening!"

- Music Composer of Titanic Paul Peabody, New York, USA

 

 

 

Architect Trupti Doshi's meeting with music composer and violinist of 'Titanic' Mr. Paul Peabody has been narrated in her TEDxAssiRd talk - Making Smart Building before Making Buildings Smart.

POETRY

 

“This world was not built with random bricks of Chance,

A blind god is not destiny’s architect;

A conscious power has drawn the plan of life,

There is a meaning in each curve and line.

It is an architecture high and grand

By many named and nameless masons built

In which unseeing hands obey the Unseen,

And of its master-builders she is one.”

 

-       From Poem Savitri by Sri Aurobindo

 

“...And of its master-builders she is one.”
