Kaya Kalp

The sandstone ghats of Maheshwar

On the North bank of the River Narmada, in the central Indian state of Madhya Pradesh is the town of Maheshwar, old capital of the Holkar kingdom. Mentioned in both, the Ramayana and Mahabharatha, it rose to prominence during the peaceful reign of Maharani Ahiliyabai Holkar in the 18th century.

The fort which houses the palace and other important community buildings, opens out on to what are, arguably, the most beautiful sandstone ghats in the whole country.

This place is home to the famous Maheshwari handloom sarees with their distinctive designs and silk/cotton blend. The Kaya Kalp project was commissioned by Rehwa Society, a highly successful co-operative that markets local products at exhibitions throughout the country.

When Rehwa Society began with a single weaver about two decades ago, there were a handful of looms in the entire town. Today, close to a thousand of them operate in and around Maheshwar. Kaya Kalp was the brainchild of Sally and Richard Holkar who felt it was time to repeat the Rehwa success story in other weaving communities in Madhya Pradesh, where the local skills are being lost due to lack of exposure.

Careful attention has been paid to the materials used in construction. The consumption of environmentally expensive materials was minimised. With no wasteful reinforced cement concrete anywhere in the building. The load-bearing structure is built from locally made burnt brick, set in a mixed lime/cement mortar. There was minimal plastering of the external walls and certainly none on the inside.

The roof framework has steel trusses covered by corrugated galvanised iron sheets  which are, in turn, clad with interlocking half-round terracotta country tiles. Together they create an insulating air-gap that keeps the rooms cool, even in the 46° Celsius (115° Fahrenheit) summers. The combination also prevents even the slightest leakage, which could easily ruin many days of work as it lies stretched out on a loom.

Steel trusses below the iron roofing sheets are very durable and can easily be reused or recycled at the end of the building’s life span. I am happy to say that, though the Maheshwari people were initially sceptical about the efficacy of this system, it has now become their “industry standard”.

The dyeing area where the yarns get their colour

The dyeing area where the yarns get their colour

Kaya Kalp covers a total area of 7500 square feet (~ 700 m²) and has been built (in the mid-1990s) at a cost of just Rs. 105 per square foot. These figures surprised everybody because no inferior materials or processes were used. It must be mentioned though, that local labour is very cheap and contributed greatly to lowering of the overall cost. On the other hand, other similar projects in Maheshwar at the time had cost up to three times as much.

I would like to take this opportunity to thank Poonamchand (affectionately known throughout Maheshwar, simply as “Ba”). He was among the last of a dying breed of master-builders and a repository of knowledge on local construction methods. Without the knowledge and experience of this young septuagenarian, Kaya Kalp may never have turned out as it was intended. I would also like to acknowledge the valuable input given by Architect Sanjay Prakash at the initial stages.

Architecture

This has always been my favourite area of work – even more than interior design – because it gives me the best opportunity to follow my ecological design principles. The ultimate aim is to show that construction can be economical and nature-friendly at the same time.

Trees, Landscaping and Microclimate

A bunch of new pages have been added to the sustainability section of this site and deal mainly with landscaping, appropriate plantation and how to create a garden to attract birds and butterflies.

Many people seem to want to disconnect their property from the surroundings but it should be the job of the architect and the landscape designer (if there is one) to ensure that a project is a part of the environment in which it resides because a building’s footprint extends beyond the area that it covers – it includes the impact on the surrounding land and on the earth’s resources as a whole.

Kaya Kalp Project – Early Example of Green Design

This project, completed in the mid 1990s, is an early example of green design in India – long before the term became popular with most Indians.  It was built using mostly local materials and at extremely low cost but there was no compromise on quality, comfort or aesthetics.

While it was designed as a training centre for handloom weavers, the flexible design allowed it to be used temporarily as a school as well as a community centre.

I have not been to Maheshwar in years and have no recent photographs but I know that the trees have grown well because they are very clearly visible in satellite pictures.

Rating System for Water Efficient Fixtures in India

The Centre for Science and Environment (CSE) has prepared a background paper for the ministry of Urban Development on a rating system for water efficient fittings and fixtures in India. This is much-needed and will (like with the BEE ratings for energy efficiency) help architects who are interested in sustainable design in the choice of taps, showers and sanitary-ware.

The paper has some typos and errors but overall, the information is extremely useful -if a little technical. Free registration is required to download it from here.

If You Really Must Have a Glass Façade, Read This

I’ve been a strong critic of glass buildings in hot places like Mumbai or Delhi but recognise that it may be appropriate in more temperate climates. One thing that had escaped my attention, though, was the hazard that such buildings have become for birds.  The thing is, birds don’t see glass façades the way we do – in fact, they hardly see them at all – which is why they are known to fly straight at a glass building and be killed or maimed by the impact.

It costs a lot more to make a bird-friendly glass façade but, at least, we now know that such an option exists.

Energy Calculator for Air-Conditioners in India

More and more people are installing air-conditioners in their homes these days thanks in large part to the concrete hot-boxes being constructed in our cities and the heat-island effect. Added to that is the fact that many commercial buildings have senseless glass façades – which makes them even-hotter-boxes. Net result: the amount of energy being consumed in urban areas is rising at an alarming rate.  The archaically-named Bureau of Energy Efficiency or BEE has been more proactive than many other government agencies in trying to make a change in this regard.  They’ve created mandatory star ratings for refrigerators, fluorescent lamps and air-conditioners and voluntary ratings for other appliances like fans and geysers.

They’ve also created an associated site with a great energy calculator that you can use to check how much money you would save by using air-conditioners with higher star ratings.  I’ve seen similar calculators on the net that cater to the USA or Europe but it’s great to have one that is valid for us in India. It basically tells you how many rupees you would save based on your usage and on city you live in. At this time, there are 17 major Indian cities in the list and, if you can’t find your own, look for one that has a similar climate and temperature range.  You must remember that such calculators make lots of assumptions so while they should give you a fairly accurate idea, don’t expect that figures to be 100% accurate.

The site also has some basic tips on saving energy and I feel that BEE should make calculators for other appliances as well – especially light fittings and fans.

Now if only they’d remove that asinine piggy-bank mascot…

LEED and Indoor Air Quality

This is an interesting and a whole new angle on the LEED debate. Essentially what is being said is that tightly sealing a building (to make the air-conditioning system more energy efficient) also locks in hazardous chemicals with complete disregard for indoor air quality.

Ideally, in our climate, we’d have less “sealed” buildings and more that could breathe. Of course, to do that, architects in India need to first stop designing climatically inappropriate glass façade buildings.

“Windancer” Windmills Have Some Great Features

With their windmills starting rotation in breeze as light as 1m/s, Wind Simplicity’s designs would be great for many parts of India that are not on the conventional wind-map. They are built to withstand snow and ice – not problems we face every day in our tropical climate!  Now if only some Indian manufacturer would tie up with them to make these in India…
