Dear InspiredReaders,

I am happy topresent you GreenInspiration or yourmind. Te articles we

have compiled thistime are ocusing onthe Future o Green

Buildings, and I am sure some o our articles willmove you and motivate you. I had the pleasureto sit together with Architect Karan Grover andArchitect Christopher Charles Benninger or aninterview, and besides all their great building designs they have even more ascinating ideas orthe uture o the Green Building Movement. Youcan read about uturistic green building design, get

some ideas rom Suzlon's One Earth headquatersin Pune and get to know diferent Green Building Rating Systems around the world. Special thanks goto our Sponsors who made it possible that Inspiredto be Green is now reaching out to over 7000 GreenBuilding Enthusiasts.

Our passion is to motivate people to go Green andspread awareness on how to build Green. Over thepast ew month we have been working togetherwith our Initiators rom Aluplast, Breezair,Everest, Nippon Paint, Supreme Petrochem,Roca and eam Sustain on an innovative GreenBuilding Concept: ZERO ENERGY SPACE. It is anew dimension o building design with the latestGreen Building echnologies in the market. Tisspace gives people the chance to experience a highcom ort indoor environment with (net) zero energy consumption. Experience the ZERO ENERGYSPACE in your city at the Green Building Congressin Chennai, Economic imes ACEtech in Mumbaiand at Economic imes ACEtech in New Delhi andsee the website www.zeroenergyspace.com

AN

INSPIRING

INTERVIEW

WITH Ar.karan

grover

Ihad the chance to sit down withone the most well known andappreciated Architects in the GreenBuilding Community: ArchitectKaran Grover. I entered his houseprepared with 8 questions and aftera wonderful 60 minute session, I

walked out with a recipe on how tochange the world.

Here is the recap of this inspiringinterview with the maestro himselfWe started with one simple question;How will a green building look 20years in to the future?

From this we moved from topic totopic, with Karan Grover expressinghis views and opinions

~ Isabelle, Editor Inspired to be GREEN

Indias Future Green Buildings:In twenty years, a green building in India will re ect the Indian

culture much better than these days where we are striving

towards modern buildings copied from the West. Design

elements like jalis and other passive strategies which keep thebuilding cool will be followed. We will rediscover the roots of

the past what will in uence the aesthetics of the new buildings.

For every place and every climatic region buildings will show

different design features which support natural ventilation,

natural lighting and cooling. Looking at developments around

the world it is fascinating to see that modern buildings in the

West are taking advantage of Asian design elements like screens

and numerous passive strategies.


7/56

From Ratings to Standards:

Today we are focusing on rating systems more then onactual green design. People started to think in LEED-points rather than following passive design from thebeginning. A shift will happen. Rating and certi cationsystems will lose in importance but standards will beincreasing. Let me explain that to you: A LEED ratedbuilding does not necessarily re ect green design. Inthe future we will aim to increase standards instead ofhunting for points. Rating systems get negotiable andare guidelines on the way to a green building. Architectswill raise the benchmarks; we will see buildings asNet-Zero, self-sustaining development or Plus-

Energy and not anymore as Silver, Gold or Platinum.

Green Community and CollectiveBeneft:

One green building in the neighborhood of thousandsof non- green buildings does not make a big difference.It is about our environment, our neighborhood, ourcity; I am looking towards an integrated green designlike green townships and green cities. We need tounderstand the collective bene ts of communitiesadopting green standards. Green communities are thebase for a sustainable, healthy and ful lled life. In the

present we can see egotistic developments focused onlyon our own bene ts, but the time will bring changes

and we will rediscover to think as a community.

The Magic of Nature:

It cant be described in words, what the beauty ofnature is. It must be experienced an early morningwalk through the forest could make us more sensitive.The sound of nature, the beauty of each tree and planthas a positive effect on human beings. We need torediscover our mother nature. Once people experiencethe beauty, they will demand this beauty also intheir buildings. We would demand buildings withindividual character which also give us the possibilityto interact with nature. Parks and landscaped areasaround the building are important to nd relaxation,and we will realize the positive effects when we spendtime with nature.

Technology, Tradition and Design:Passive strategies and design is crucial for everybuilding, new technologies are there to support, butnot to replace passive strategies. Photovoltaic panelscould be integrated in a faade design supportingthe passive strategies, and offering the bene ts oftechnology. Buildings have identity and we shouldaim to root this identity to our place. Nowadays it isarchitecture of space, buildings all over the world lookthe same without considering the place, the tradition

and the culture. We need to root our buildings to ourplace, than buildings will also be more connected topeople. Aesthetics should be based on individual

culture that people can relate.

Build a Green Building YOURSELF:

I want to share the basic green design strategies, which every architectcan easily incorporate in the design to create a green building. It is amisconception that we need a green architect, a green consultant and thebest green rating system to create a sustainable building. We should just askourselves what we de ne as green, that will lead into the right direction Iwill share an easy recipe with you:

Look at the orientation of the building. Make sure that smaller surfacesare facing east and west.

Design buffer zones on east and west facades like verandas, equipmentrooms and staircases.

Integrate screens to allow natural ventilation and cross ventilation tocool the building.

Design inclined windows on the south faade to avoid direct sunradiation on the windows.

Try to avoid any openings like windows on the east and west. Use ceilings which re ect the natural light and bring

it deep into the room. Use green roofs and green walls. Design rainwater harvesting pits to collect all rainwater from the site. I believe the success of developing a Green Building Community lies

in sharing information without making yourself to the key-person.Teach people what they need to know to make a green building.

Everyone Is Green:I can see that every second developer promotes his project with the help ofthe word green. Most of the times it is only a word, and there is actually noelement which is eco-friendly, energy-ef cient or sustainable in this project.We should employ green watchdogs who will ask developers, buildersand product manufacturers to prove their green statements. Consumershave the right of information and under no circumstances they should bemislead with the word green. Stand up and ask for the green features and if you dont feel it is green, speak up!

We Can Change The World:There is no community which has a greater impact on the worlds energyconsumption than architects. 50% of the worlds energy is consumed bybuildings. Architects can save at least of the buildings energy consumptionby passive design elements and with the help of energy-ef cient technologies.That means by designing our buildings in a sustainable and energy savingway we have an impact of 25% on the words energy consumption!

If we work together we can make an extraordinary difference. Ourcommunity is responsible for the survival of this planet. Lets goout and change the world!

Inspired to be Green thanks Architect Karan Grover for his valuable time towardsthis motivational article.

Green Facade systems From KinGspan

K ingspan Insulated Panels have been present in the India marketfor 3 years with their cold store sandwich panels and roof sandwich panels for industrial buildings. The Ireland based globalmarket leader has now announced the launch of their insulatedfacade system designed for building envelopes of commercial

and public buildings.

The use of these products in India is now necessary for the compliancewith the green building concept as well as to comply with the newECBC requirements. The Kingspan system delivers 6 to 8 times better thermal insulation values than the conventional 9 inches brickwork.This of course means a signi cant cost saving by reduced heat transferthrough the building envelope. On top of the usual requirements of water tightness, dust tightness, thermal and structural performance,the aesthetics of the system have been a top priority for the design &manufacturing of this product.

Kingspan has 30+ years of experience with manufacturing insulatedsandwich panels on continous manufacturing lines. Their facadesystem has been used in many countries in America, Africa, Europe,Middle East, Asia & Australia.

The panels combine an amazing insulation value with the aestheticsof the modern metal based rendering systems. Case studies show awhopping INR 400+ savings per annum on every m sq of the panelsystem. As per recent studies the panel system would add up to extra3 LEED credit points as compared to conventional brick based wall.

The other bene t of the system is the elimination of wet trades no brickwork is required and the system is prefabricated hence the risk of site errors is minimized. Kingspan is a member of the Indian GreenBuilding Council. A wide range of FM Approved Firesafe productsare available within their product range.

Besides launching their facade system Kingspan continues to supplytheir roof and wall panels as well as cold store panels.

G reen has been a fashionable word these days. Unfortunately, more often than

not it has remained a word rather than a colour. As a result it gets interpreted in numerousshades. While on one hand fully glazed buildings using a photo sensitive glass product maybe rendered as green, on the other end building with adequate comfort conditions withoutuse of air conditioners would not nd favours with the LEED rating system. There needs to be a

boundary de ning the blacks and whites of the green. No doubt that with the current state ofaffairs, which has rendered the environment dismal grey, every possible shade of green maybe a welcome tone. Range is vast but we still need to de ne priorities.

While, turning off the television at night, rather than keeping it on a standby mode can savebillions of Rupees worth of Energy (50 million pound estimated for entire UK in a year). We stillneed to identify our own spectrum of green and chart strategies around the same. It has to bea contextual resolution rather than a global statement. Universal-global norms have been oneof the major factors in aggravating the problems. For example, even for the basic essentialtasks there are such diverse norms existing in the world that universalising them with the higher denominator as the benchmark will only remain unduly wasteful. For example, an averageconsumption of water in USA is 600 litres per person per day, in Europe it is 250 litres, 135 litresis the Indian average while in Africa they manage with as little as 30 litres per day. India has8 vehicles per thousand as compared to nearly 800 of America. Ninety percent of wordscars are owned by sixteen richest nations accounting for only one fth of world population.Need India follow the suit? India ironically ranks fth in the energy requirements. Of whichbuildings account for nearly forty percent. (Residences 23.4% and Commercial buildings 6.6%).Industries follow next with 36.5% and agriculture 30.7%. As a development agent dealing withthe building industry it makes us quite responsible for our decision making.

Redefining the

Greys of the Green

I n a daytime use building nearly ninety two percent of energy is spentin cooling (60%) and day lighting (32%). The same gures for residential

buildings are 64%. This makes it quite logical for us to prioritize cooling andday lighting to be the preoccupation of the sustainable designs. How doesour decision matter in these aspects? For example a building type can bea critical decision for its energy demands. A multi owner high-rise residentialbuilding has energy demands of (59.8KWH/sq. M) one and half times thatof the single owner low rise building (40 KWH/sq. M), owing largely to theelevators and the energy intensive services. Entertainment centres guzzlethree and a half times (135 KWH/ sq. M) while hotels and data centresare ten times more intensive. But topping all the list are the recently foundshopping malls pegging energy needs at 565 KWH/sq. M. Needless is thedebate whether after all these if they even measure up to the plurality andvitality of the traditional street bazaars. Air conditioners take up nearly half ofthe energy demands consuming at 1000 watt unit rate versus a fan which isonly 80 watts. Do we need to chart an agenda for twenty percent reductionof air conditioning load to resolve to nd comfort without one? It is also afallacy to think that modern times imply more comfort. Electricity has beeninvented and applied since over two centuries but the energy consumptionof entire year of 1950, even after 150 years of its invention, is equivalent oftodays consumption of six weeks only. And yet it remains inaccessible toover 40% of worlds population. Where has it got consumed and what are itsalternatives? Entire estimated stock of fossil fuel of the world is equivalent ofeleven days of solar energy. Moreover one kilowatt of solar panel saves oneton of carbon dioxide. In last fty years worlds population has doubled andthat along with the enhanced consumerism has put strain on the resources.Not to mention the severities of alarming pollution levels. In this reality ofworld and times of inundated construction can we pull ourselves back toquestion the taken for granted conclusions?



22/56

I t still makes sense to apply commonsense andconventional wisdom in resolving architecture. As

architects we are called to take six basic decisions and thesum total of which is architecture.

A) Sitting and location : This has severe implication throughorientation, exposure and impact of natural forces. In westernhot arid zones of India orienting a building with its longer facesto North-South compared to East-West can reduce solar radiation and exposure and thereby the energy demands tonearly half.

B) Form and Mass : This has potential for confronting naturalforces as well as to bene t from mutual shading and scaling.As a thumb rule exposure levels and thereby energy demandscan be reduced in a building in hot-arid zone up to tenpercent by optimising on volumes of the building in areassuch as passages, verandas, toilets, alcoves etc. Somethinglike split levels. By adding a oor with reduced radiationfrom the top it gets reduced to about twenty percent. It isnearly halved by attaching the building from sides as wellas stacking oors above.

C) Space organisation : This governs the extrovertedness or introvertedness, compactness or fragmentation, along withdirectionality and exposure value of the architecture. For example traditional buildings from hot arid regions have beencompact, stacked and attached in their form, and havebeen interspersed with multiple yet small scale courtyards toreduce heat gain. As against Bungalows of the hot-humidzones have been extroverted with veranda like living spacesin the periphery to increase its transparency to breeze.

D) Elements of Space making : This forms the essentialsyntax of the architecture and thereby its interactivity withexternal conditions. For example a pavilion like structurewith prominence of inclined roof form versus lightness-oftenabsence- of wall is the syntax of hot-humid climate. Converselypredominance of wall and subjugation of roof is the grammar

of hot-arid climate zones.

E) Material and Construction techniques : This is vital in settingforth the chemistry of building with external elements throughits thermal coef cient, material properties and dynamicsof its physics. If sunburnt clay block is taken as an unit ofenergy demand of material, cement is nearly ten timesas energy intensive, steel thirty times, PVC 120 times andaluminium 160 times.

f) Finishes and surface articulation : Although seemingly micro,the skin rendering turns out to be the rst aspect of buildingto negotiate with environmental conditions. As the rst linesoldier it takes most of the brunt of the vagaries of nature.Dark versus white or very light colour rendering with glossier surface can create up to ve degree temperature differencewithin through its high re ectance value.

Any building, good or bad, demands the architecturaldecision on these six aspects. If only we understand thewider implications of these decisions we would be able tomake informed choices and arrive at the resolutions basicallysustaining. While smallest details can matter and advancedtechnology can help further in achieving ef ciency ofenvironment management these device or technologybased solutions come later after the basic architecturalresolutions. For example if heat gain through clear glassopening is seen as 100% the double glazing can help reduceit by about ten to twenty percent. The tainted glass canreduce by about forty percent. As against external awningor a meter wide eaves band can reduce it easily by over sixtypercent. Thus technology does not absolve us, as doctor ofvital forces, from our primary responsibility of managing thebasic architectural resolution in consonance with the forcesof nature and the local context.

So the debate is not about shying away from the technologicaladvancements but rather to let it play as second ddle andnot to hide architectural fallacies behind the facades ofenergy intensive technologies. Through history we have knownof full wall openings or undeterred views but we resolved themeither as perforated Jaali walls in Rajput or Islamic phase or asstained glass openings in colonial phase. Both discouraged

ingress of heat and yet provided extended views from insideout while protected outsiders peek within. Smaller aperturesof Jaali created microclimate features to induce velocity ofair and cooling of air particle through Ventury and Bernoullisprinciple respectively. There is no logic for omission ofoverhangs for curtain glazed western or Southern facades inpresent day buildings, in our extreme hot climate condition.We seem to have left our bearings somewhere...

Here is one of the interpretations to demonstrate sustainablebuiltform using recycled waste material.

Manavsadhna Activity Centre is the very differentinterpretation of sustainability. A community centre in asquatter settlement, it uses the building components recycledfrom the domestic and municipal waste. The entire buildingis the demonstrative application of waste recycled productsindigenously developed. Recycling the waste answers thecall of environment through reduced pollution, empowersand employs the poor through value addition processes,and helps towards affordable and durable housing as theseproducts are cheaper and more performing than the presentoptions. The building uses y ash bricks, dump ll site wasteresidue bricks, stabilised soil blocks, wood crate panels,glass bottles and waste lled plastic bottles etc. for wallingoptions. It uses cement bonded sheets with clay tiles, stoneslabs, glass-plastic bottle lled ller slabs etc. for the roo ng,wrapping waste reinforced F.R.P., oil tin container panelling,wood crate panelling etc. for the doors and windows and inparts waste- y ash-china mosaic tiles and blocks for ooring.These become live demonstrations for the urban poor toemulate in their homes.

The team at Inspired to be Green would like to thank Architect Yatin Pandya for sharing his valuable time and insights onGreen and Sustainable Architecture with us. We will be covering 2 very interesting projects by Ar. Yatin Pandya in our next issue.The projects are the Environmental Sanitation Institute and the Gandhinu Gam Ludiya.

Teatro Del Agua by Charles PattonCharles Pat n has c me up ith his Sea ater Greenh use Pr ject,which takes a low-cost, low-energy, carbon-neutral approach todesalina n.

The Teatr del Agua, u lizes energy fr m the sun, the sea and theatm sphere t create c ling and fresh ater. The pr cess is based

n the Sea ater Greenh use c ncept and the range f p ssibili esf r c ling is c nsiderably enhanced by using sea ater. This is arela vely ne devel pment, requiring the use f l c st plas csf r pipes, pumps and heat exchangers (metals that are adequatelycorrosion resistant to seawater are generally too expensive for suchapplica ns).

The Teatro del Agua works by coupling a series of evaporators and

condensers such that the airborne moisture from the evaporatorsis then collected from the condensers, which are cooled by deepsea ater. The s eeping structure ill inc rp rate s lar panels tpr vide heat f r the evap rat rs and ill perate alm st en rely

The pr p sed devel pment c vers an area f ab ut 400 000 squaremeters. In the sunny climate f the Canary Islands, the am unt f s lar energy falling n this area is very large, reaching ab ut 320 MW.If, f r example, just 1/10th f that energy ere used t dis l fresh

ater fr m sea ater, ar und 300 m3 per day f fresh ater uldbe pr duced. The buildings are thus self-su cient in ater, and thesurplus is su cient t irrigate s me 50,000 m2 f gardens.

Dice House by SSybarite, a Bri sh Architecture rm has designed an extra rdinaryarchitectural c ncept f Dice H use. It is a zer carb n h meemphasizing the utline f the Dice.

Prof. ChristopherCharles Benninger

Director, ChristopherCharles BenningerArchitects Pvt.Ltd

I had a wonderful conversation with Christopher Benninger at his breathtaking of ce and residence, India House,at Pune. ~ Isabelle, Inspired to be GREEN

Isabelle: Sir you have designed many sustainable buildings and mostrecently the Suzlon One Earth campus that is LEED Platinum ratedand also received the Five Star rating from TERI-Griha what is thesecret behind your sustainable design?

CCB: We are applying a lot of thought when we design a building; we are using thegiven conditions of the place to our advantage to save energy and save resources.For example, here in India House, the orientation was chosen to maximize natural

ventilation. The open courtyard allows the wind to enter and cool down the building ina passive way. Louvers in front of the windows are designed to block direct sunlight,allowing tempered natural light to enter deep into the rooms. Since they are operablewe can control the light throughout the day and in different seasons. We have selecteda good re ective color that bounces the light deep within the rooms. We have used athermo-isolative material on the roofs that cuts temperatures by ve percent and thelight re ective tiles on them re ect the sunlight and further cool the roofs. It is easiest tostart the battle at the envelope edge than to bring it inside the structure.

Green design is not only the concern of architects. It is the task of the entire project teamand the owner who must bring a passion for green design in to the building process. Agood deal of the approach deals with the location selection, the site development and theday to day management of the earth works, vehicles, and the attitude toward the peopleworking on the site. You cant just put the whole responsibility to the architect, thinkingthat by sitting in his studio he will just specify and design the solutions. The leadershipand the sense of mission, and the passion for a sustainable world must emanate from theclient. We all need to bring ideas on to the design table. This is the only way we createa green community and build sustainable structures.

GREEN BY NATURE:GREEN BY RATINGS


29/56

Isabelle: You are talking about a greencommunity, what status will green buildings havein the future?

CCB: Buildings in themselves are microcosms of cities andwe should start to treat buildings like that, as a micro unitof a bigger system. Green buildings are micro models of

sustainable systems that must be ampli ed to the macro scale.While the number of rated green buildings is expanding, itwill always be a miniscule share of the total built fabric of urban form. We now have to think of Sustainable Cities of which these individual structures are just like the biologicalcells of the city, or small parts of urban fabric. Their roles areto demonstrate and to show the way. They are not the solution.

There is a natural way of building. We all used to do that bynature several decades back. It was just the way we workedthat made us design buildings that had cross ventilation, thick walls for insulation and plenty of light off of the verandahs.Here were vents at the top of the ceilings to release the hot air that rose up.

Maybe ten years back we had just ten building materials onour pallet and they all came from nearby areas. Suddenly wehad a plethora of complicated, new and composite materials.We started to air condition everything. Aluminum CompositePanels cladding everything became the in thing. Hermeticallysealed, stuffy and dark rooms became the norm. From green

by nature we started designing bad, irresponsible and rude buildings that insulted ones sense of good manners. Now thatwe switched from designing in a green by habit manner, westarted designing just plain bad buildings that guzzled energy, polluted the air, wasted water and required arti cial lighting.We were specifying toxic materials that required a huge carbon

footprint to produce and to transport. Then the idea of makingus learn by numbers came on the scene. Giving us points for doing the wrong thing a little bit better caught everyonesimagine. We are all basically children. We are anal-retentiveseekers of attention. So Hey, look at me, I have more green

points than you, was a very good idea. I think the green ratingsystems are trying to make bad things a little bit better. Thisteaching tool and game is a good beginning. But it is not theway to solve the worlds environmental problems. I would liketo start at Point 0 and outline the picture.

If you look at the pattern of early human civilization you cansee that villages always developed around a micro-watershed

catchment area, with dense vegetation and forests housing oraand fauna and a wide variety of biomass. The insect and birdlife was intermixed into an ecologically balanced system, of which mankind was just a small part. As villages grew peoplerequired more and more land for agriculture and rewood . . .and here the problem starts. More land for agriculture meansthat forests, and the supporting biomass were cut and burned andtransformed into elds. During the monsoon, after the biomassis removed through harvesting, the topsoil of the gets washedinto streams, rivulets, rivers, lakes and oceans. The rainfall inthe catchment areas remains within the same volume and thecarrying capacity of the drainage systems are reduced throughsiltation. Filling in from the bottom the streamsides erode andwiden, collecting more silt making the rivers shallower! Thisresults in ooding and the powerful ood currents erode moreand more land. Meanwhile the cutting and burning of the hillslopes and tops continues unabated. The forested hilltops aredenuded of their rewood! Goats and other domestic animalsgraze over the barren lands, eating the biomass coverage andchewing away even the roots of protective plants leaving thehills unprotected. What soil is left is blown away in the hot, drysummer winds covering the countryside with dusty pollutedair. Dense forests with wildlife and sh lled streams becamedesolate wastelands.

At the same time our population continues growing. We try tosolve this problem by using chemical fertilizers and pesticides

to grow hybrid plants that promise abundant harvests. Theseweak crossbreed plants cannot survive without chemicaltreatments. The treatments are toxic and these poisonsdeteriorate very slowly, nesting into aquifer systems and

poisoning the subsoil layers.

Now we have solved our rst problem of amplifying the foodsupply to feed the enlarged population, but we have createda new problem for the environment. All the chemicals andtoxins are now washed into the subsoil, the subterranean water reserves and the aquifers that keep the water system vibrant.Many of the cash crops, like sugar cane, are water guzzlers.One acre of sugar cane requires enough water to irrigateseven acres of leafy green vegetables of food crops. It is moreexpensive to grow sugar cane in India than to import it from

tropical rainforest areas like Cuba and Malaysia. So even therural economy becomes dependent on an unsustainable modeof agricultural production. The Green Revolution is not sogreen after all.

We have started the same vicious cycle with our buildings.First we made use of regionally available materials and triedto use the weather conditions to our advantage by designing

buildings that allow natural ventilation to cool our buildingsand daylight to illuminate our spaces. Slowly we started tomove away from our traditions. We developed buildingsthat are very uncomfortable without the help of technologieslike air conditioning, elevators and arti cial lighting. Wedeveloped sanitary systems that demand huge per capitaconsumption of water. H ere we are, right now, trying tosolve the problem of our energy-guzzling buildings. We call the solution Green Buildings. That is actually the pointwhere we are trying to make something bad a little bit better.We start with the wrong assumptions and we do the wrongthing better and better and better. We get points for doingthe wrong thing better and better. We try to reduce energyconsumption with new non-toxic materials and incorporatesystems that are more energy ef cient. But we have no ideaabout the ecological impact of production of those materials.

New technologies come from all over the world to cut downon energy bills, but have we ever thought of how much

energy is spent in transporting these materials, equipment,and their inputs around the world? Do we know what toxins

are emitted during production or are latent within the nished products? Yes, we are learning to do the wrong thing better and better, but we are doing it wrong from the beginning.

Isabelle: You are right, I have not thought aboutit this way.

I will give you another example that may open your eyes:

The GREEN REVOLUTION involved the introduction of

high-yield varieties of hybrid seeds after 1965 and requiringthe increased use of fertilizers and irrigation. This scienti cfeat provided the increase in production required to makeIndia self-suf cient in food grains, thus improving agriculturein India. This movement is now is blamed for the spread of land degradation in India due to excessive use of fertilizersand pesticides. It requires immense amounts of capital eachyear to purchase equipment and fertilizers. This may leadto a cycle of debt if a farmer is unable to repay the loansrequired each year. Additionally, the crops require so muchwater that water tables in some regions of India have droppeddramatically. This drop continues affecting negatively the process of deserti cation. Where cash crops demand highlevels of irrigation the evaporating water creates salinizationdestroying the fertility of the land. Already, the low water is starting the process of salinization. If continued, this willleave vast land tracts infertile and spelling a disaster for India.Fifty years ago the Green Revolution was started for agood cause and saved millions of people from death andstarvation. Now the environment must bear the cost, and wewill be affected soon. I do not wish the same process to take

place with our buildings. We should think about sustainablesolutions without negatively effecting the environment.

Let us design buildings with local resources,incorporate technologies carefully and pay a lot of attention to a balance with Mother Nature.

About CCB:

Christopher Benningers early career was as a teacher at Harvard University and in India, where he founded the School of Planning at Ahmedabad and the Center for Development Studies and Activities under the University of Pune. Sixteen yearsago, well past the age of fty, he gave up a thriving academic and United Nations consulting career, starting an architecturalstudio nearly from scratch. Along with his partner, Akkisetti Ramprasad and senior colleagues Rahul Sathe, Daraius Choksi,Harsh Manrao and others, an architectural studio was quickly turned into an internationally acclaimed design house, winningthe prestigious American Institute of Architects Award, Indias Designer of the Year Award amongst others. Their studios

T he On Premise Laundry (OPL) segment of themarket is de ned as Healthcare or Hospitals, Hotelsand large Flight Kitchens that launder their ownlinen in their own premises or in-house. The washers inthese segments range in the size from 10 to 200 kgs capacitymachines. These accounts choose to process their ownlaundry in-house for the following reasons:

In some cases it is more cost effective to wash linen on premise.

It gives the user complete control over the wash qualityof linen which in the long term helps in controllingcost on account of linen discards.

It helps the user to set and maintain linen standards.

The ve basic variables that affect cleaning performancein any laundry operation are:

Water Agitation or Mechanical Action Time Chemicals Heat or Temperature

The proper balance of all the above brings about maximumcleaning economy and ef ciency. To maintain work qualitywhen one variable is changed, we have to compensate bychanging the other. All OPLs typically try to maintain this

proper balance. The laundry wash formulas which are aseries of operations or steps designed to loosen, suspendor remove soil from linen are also critical in ensuring thatwe achieve the desired economy and ef ciency. Most of theOPL today use the standard high temperature wash process,which involve high temperature, high alkalinity and highdetergency action. This in turn leads to higher water,energy and power cost.

Once the soil is removed from the surface or linen, the leftover is stain which needs bleaching action will mask or decolorize it.Bleaching operation predominantly has both Chlorineand Oxygen as bleaching agents. However excessivetemperature can be detrimental in some parts of the washcycle. Bleaching in high temperature can cause fabricdamage or can result to setting of stains in initial stage.High temperature systems also mean higher consumption of energy which is required to achieve the desired performance.

Many OPL today, sometimes have machines which becauseof technical or mechanical problems are unable to providethe required high temperatures. In such cases most usersend up compromising on wash performance. There are alsoconcerns of water hardness in many parts of the countrywhich can be an issue. In high temperature system, scaling

deposit on the fabric and machines which lead to reductionin machine and fabric life. Thus:

High energy leads to high fuel consumption whichincrease the cost

High temperatures leads to high linen deteriorationwhich again results to higher cost

High temperature systems will have wash formulasdesigned of high alkaline, that provide the potentcleaning force which helps to mask stains. However when the same is discharged to sewage, would increasethe COD and BOD levels, resulting in an increase insewage treatment cost.

To offset all the above critical points, OPL are now movingto a new concept of low temperature and low alkalinity wash

process. The distinctive advantages of the low temperaturesystem are:

Energy savings up to 30% due to lower temperature Water savings up to 28% Productivity savings up to 30% due to shorter wash

processes Af uent reductions up to 30% due to reduced water

consumption Extended linen life up to 30% due to lower temperature

wash processes.

A low temperature wash process provides the user with the above mentioned possible savings because of a combination of:

Good wetting agent Low temperature bleaches

This low temperature system, which uses a milder bleachingsystem and lower temperature, will be the future of OPL. Asresources like water, energy, power are scarce & expensive,it will become the need of the hour for all OPLs to moveto a processes which will consume less water, energy and

power. Many local municipal corporations today havealready regulated supply of water to OPLs and to full ll

balance needs, many of them get water supply from wells,tube wells and tankers.

As water is the largest consumable in Laundry and singlemost important factor that can affect the quality of wash

performance, it becomes important for all OPLs toadopt the system. This not only saves water, but also lowtemperature bleach provides a superior performance. Thelow temperature system saves an over all operating cost andalso helps preserving the environment and hence achievingthe mission and goal in reduction of Global Warming.

Sustainability andGreen Buildings

around the World!

Introduction

There are many Green Building Rating Systemsout there and were about to give you someinformation about the larger, more in uential ones.The following list of nations represents a signi cant

proportion of the Earths population and eachnation listed here is at least attempting to answer the call on why we must live more sustainably.

Sustainability in the United StatesThe United States, with approximately 300million people, is the largest consumer of energyin the world. In comparison, the average Indian isone of the worlds smallest consumers of energy.The majority of the energy consumed in the UScomes from fossil fuels with less than 9% fromnuclear and around 7% from renewable energysources. Paradoxically, the United States, withits huge appetite for energy, is also a world leader in sustainability initiatives. There are several

notable rating systems in the US of which wewant to talk about LEED, Energy Star and GreenGlobes for this article:

USGBC: First, lets talk about the United StatesGreen Building Council. Founded in 1993, isa non-pro t trade organization that promotessustainability in how buildings are designed, builtand operated. With over 20,000 members, theUSGBC is best known for the development of the

Leadership in Energy and EnvironmentalDesign or LEED green building rating

systems and the annual Greenbuild

conference and exposition that promotes the green building

industry.

LEED

The LEED building rating system is broken into6 different credit categories for which points areearned based on the green merits of the project

being rated. With over 25,000 registered projects,it is the largest green rating system in the US. TheUSGBC established benchmarks for the LEEDgreen building rating system in 2000. LEED isa framework for assessing building performanceand meeting sustainability goals. Certi cationis generally voluntary, but is quickly becominga requirement to follow the LEED protocols for government buildings and in certain localities.

GBI - Green Globes

Green Globes is an environmentalassessment, education and ratingsystem that is promoted in the United States by the GreenBuilding Initiative, a Portland, Oregon-based non-pro t.

The system, which is an on-line interactive software tool,awards points under multiple categories. Currently, Green

Globes has over 250 certi ed projects in the US.

EPA- Energy Star

Energy Star is an international standardfor energy ef cient consumer products

originated in the US. It was rst created

as a US government program by the Clinton Administrationin 1992, but Australia, Canada, Japan, New Zealand, Taiwanand the EU have also adopted the program. Devices carryingthe Energy Star logo, such as computer products, appliances,

buildings and other products, generally use 20%-30% lessenergy than required by US federal standards. Currently,there is more than 1.9 billion square feet of oor space in the

US that has met the Energy Star label.

Sustainability in Canada

The Canadian Federal Government, throughthe Auditor General Act, has made a goal of advancing sustainable development a public

policy for all of Canada. As in the United States, federal, provincial and local utility incentives exist to encourageresponsible management of natural resources.

The non-pro t Canadian Green Building Council was formed

to promote sustainability in how buildings are designed, built and operated. As in the US, the CaGBC is perhaps best known for the development of the Leadership in Energyand Environmental Design or LEED green building ratingsystems and the annual national conference and expositionthat promotes the green building industry. Currently thereare more than 2000 registered projects throughout Canada.

The CaGBCs Green Up program provides tools, performance standards and resources to help building ownersand operators understand, measure and compare on-going performance of their buildings to help them nd ef ciencies

and improvements to achieve deep reductions in energy andwater use, and greenhouse gas emissions.

The CaGBCs Living Building Challenge was establishedas an additional outlet to promote the goals set forth by the

USGBC and CaGBC it establishes a vision for a projects

environmental and social responsibilities from a new vantage point. With more than 60 registered projects spanning thelength of Canada, the buildings are pursuing certi cation

under a more vigorous performance standard than the normalLEED process. The Living Building Challenge is not meantto compete with LEED and in fact has been endorsed by boththe USGBC and CaGBC.

BREEAM:

BREEAM is a voluntarymeasurement rating for green buildings that was establishedin the UK by the Building Research Establishment. It standsfor BRE Environmental Assessment Method. Since itsinception in 1990, it has grown in scope and geographicalrelevance by being exported in various forms across theglobe. Its equivalents in other regions include LEEDin North America, Green Star in Australia, and HQE inFrance. It is touted as being the largest and most widely usedenvironmental assessment tool in existence.

Sustainability in the Middle East

The Middle East Centre for Sustainable Development(MECSD) has a mission to promote innovation enablingsustainable development in the Middle East. The Centre willenable guidelines, technical support and Green Certi cation

within the reach of all interested parties that wish to progress on sustainable development projects in the region.The Centre was established to address standardization andintegration of Green building requirements within Dubai,establish local Energy Ef ciency certi cation and norms

and guidelines, technical support and green certi cation

within the reach of all interested parties that wish to embark on a sustainable path within the region. Some speci c

examples:

UAE & LEED

Little noticed in the US & India, is his Highness SheikhMohammed bin Rashid al-Maktoums dictate that allnew buildings in the United Arab Emirates meet LEEDstandards. Sheikh Mohammed, Prime Minister of the UAEand ruler of Dubai has mandated that all new buildings inthe emirate be meet LEED standards. As you might guess,a huge emphasis is placed on water conservation as wellas an adaptation of the standard LEED credits to meet the

unique challenges of construction in the UAE. It is believedthat this mandate will cause a revolution of sorts given thatthe worlds architects, contractors, engineers of nearlyevery large American and European rm of consequence is

designing and building in Dubai and Abu Dhabi two key

cities in the UAE .

Estidama Pearl

Estidama is a building designmethodology for constructing and

operating buildings and communities more sustainably. The program is a key aspect of the Plan Abu Dhabi 2030 driveto build the city of Abu Dhabi according to innovative greenstandards. Estidama is the Arabic word for sustainability.The program is not itself a green building rating system likeLEED or BREEAM, but rather a collection of ideals thatare imposed in an elective code type of format. However,within Estidama there is a building rating system calledthe Pearl. This system is used to evaluate buildingdesign in Abu Dhabi.

Sustainability in Singapore

As part of Singapores strategy for sustainablegrowth, the Inter -ministerial committee onSustainable Development has set a target of 35% reduction in energy intensity by 2030from 2005 levels. As buildings account for about one thirdof Singapores total electricity consumption, the energyef ciency of buildings is a prime target. To this end, the

government has already put in place both incentives andregulations under a Green Building Master Plan. Thetarget is to make 80% of all Singapores buildings green

by 2030. The government is further introducing a $100MGreen Mark Incentive Scheme for Existing Buildings toencourage and incentivize building owners to undertakenecessary retro ts to upgrade their buildings.

Sustainability in India

Finally lets talk about sustainability and green buildinginitiatives in India. Though the terms sustainabilityand green buildings are relatively new the practices

surrounding them were never new to India. Ancient andmedieval structures are testimony to the fact that Indiahas a long history in Green Buildings and sustainability.India is one of the largest growing economies in theworld with economic growth rate of 8.9%. Commensuratewith economic growth, urbanization in India is growingfast. Everyday Indias growing economy needs more

energy, water and resources for the built environment. Theconstruction sector in India is witnessing a fast growthdue to several factors. Some of the key growth drivers

are increased demand for housing, strong demographicimpetus, expansion of organized retail, increased demandfor commercial of ce spaces by multinationals and IT

hubs, and coming up of SEZs (special economic zones).Lets look at some of the sustainability and green buildinginitiatives in India.

The Indian Green Building Council represents all thestakeholders in the construction industry. It has developeda green building rating programs that cover commercial,residential, and factory buildings and special economic

zones. Rating programs would help projects to addressall aspects related to the environment and is an effectivetool to measure the performance of the building/project.IGBC along with the Ministry of Commerce and Industrydeveloped the Green SEZ guidelines. The Green SEZ RatingSystem encourages projects to exceed the requirements of many codes and standards.

HPCB High Performance Commercial Buildings inIndia is an initiative targeted at air conditioned commercial

buildings aiming at establishing relevance and impacts

of low-energy passive strategies and making themCode compliant. According to the Bureau of Energyef ciency - ECBC / Energy Conservation Building Codecompliant building use 27-30% less energy compared totraditional buildings.

TERI or The Energy and resources institute formerlyknown as Tata energy research institute has been supportingIndias Energy and sustainability demand for the last 30years. Some of Teris notable contributions include therating system called GRIHA. TERI does a lot of research

and brings value to the Indian society in areas includingalternative energy including new age bio fuel, green

buildings, bio technology, etc.

BEE - Similar to the Energy Star program in the US BEE

or Bureau of Energy ef ciency promotes STAR RATING

for electrical equipments and appliances. Recently theBEE has introduced a rating for building as well where

buildings based on Energy Performance Index gets a score between 1-5 stars. The Lower the EPI (KWh.Sq.m)

the higher the star rating.

So now you know whats happening around the world withrespect to sustainability, energy and water conservation andgreen buildings. And you also know whats happening inyour corner of the planet. We would like to end this article by a verse from the Rig-Veda Let noble thoughts come

from all sides.

Paharpur Business Centre and Software Technology Incubator Park (PBC - STIP) has been conducting its businessin a environmentally friendly manner since its inception some two decades ago and it rmly believes that care for environment is intrinsic to its business.

Introduction:

Paharpur Business Centre & Software Technology Incubator Park, is an SME, & is engaged in the business of providingfurnished of ce space on a plug n play basis, to a host ofmultinational and Fortune 500 companies planning forays intothe Indian market place, in a mountain fresh air ambience andfacilitating business through its suite of twenty-eight support

services at one stop. All its of ces are equipped with state ofthe art facilities & services.

Motto: A good environment ultimatelyleads to sustainable development.Under this PBC signed a MoU with MCD and adopted a 4-acrearea that was a slum and converted it into a beautiful park by

planting more than 2000 trees and shrubs. This tremendouslyimproved the air quality in the area, as prior to this it was aconcrete jungle with no green space.

PBC - STIP strictly follows the principle of 3 R i.e. reduce,reuse and recycle as stated in its environment policy. Over the

past many years it has taken several environmental initiatives for sustainable development without sacri cing the quality of life.

Some of the notable initiatives taken by PBC have been in thearea of energy saving, water conservation; water harvestingand indoor Air Quality (IAQ).

Environmental Responsibility:Our service business must have minimum impact on our

surroundings, neighbors and environment. Our mottoReduce, Reuse, Recycle is applied wherever practicable inour business without sacri cing quality of life.

In accordance with the above, the PBC has formulated anumber of procedures and processes to improve and sustaintheir environmental performance.

To begin with the Business Center at Nehru Place Greensis a No Smoking Building much before Government ofDelhi made it mandatory for all commercial buildings in thecity to be No-Smoking buildings. The occupants are notallowed to eat in of ces; the PBC has separate designatedareas for both smoking & eating. This was done in order toimprove the quality of indoor air & to ght the ill- effects ofsick building syndrome.

Indoor Air Quality

The Indoor Air Quality at PBC - STIP meets the speci ed

ASHRAE (American Society for Heating Refrigeration and

Air conditioning Engineers) Standards. A dedicated Indoor

Air Quality division equipped with a lab has been set up to

continuously monitor and improve the indoor air quality. PBC

uses bio-technology originally developed by NASA to purify theair. This process makes use of plants like Sensevieria Trifasciata

that produces oxygen at night, Areca Palm and Money Plant.

PBC has been practicing this natural system of air puri cation

through plants for nearly two decades now. This ensures lower

CO2 levels that result in higher blood oxygen and higher

productivity. This is done through a very scienti c system: air

from a height of 120 ft is sucked in, passed through a water

shower to free it from any water soluble particles / pollutants,

it is then pumped into a chamber / Green House which hasmore than 1500 plants that enrich it with oxygen and increase

its humidity. The oxygenated air is then fed into the AC plant

for cooling. This treated fresh air is provided to all the oors

through individual AHUs.

The AC plant has been so designed that it does not reuse the

air but takes in fresh air every time. To save energy, a heat

recovery wheel is placed that exchanges heat. It reduces the

temperature of the incoming air. A chemical cartridge has also

been installed in the wheel to reduce the poisonous gases likeSO2. As a result of this we have been able to maintain SO2

levels to below detectable limits. Other than this there has

been partial reduction in NO2 and SPM levels. The HVAC

system provides fresh air supply to 20 cfm per person. The

building is designed to accommodate 400 people at a time

with 4 plants per person.

A View of Green House

PBC offers, near mountain fresh air, in the heart of NewDelhi for those who work in the building which improves

productivity, as a person does not get tired and feels fresh, thusleading to good health, fewer sick days.

A study was conducted by CPCB MOEF, Government of

India & as per this, it was found that providing cleaner air reverses the effects of pollution. People working at Paharpur Business Centre in Nehru Place, which has lters to clean

pollutants from air, were found to have 10-12% less lungimpairment than those working in Nirman Bhawan & MausamBhawan, where there are no air lters.

Compared to other buildings in Delhi, the incidences of Eye irritation reduced by 52%, Respiratory symptoms by34%, Headaches by 24%, Lung impairment by 12% andAsthma by 9% at PBC.

PBC posts air quality readings on their website: www.pbcnet.com, please log on for the days readings.

Energy Conservation:In any organization 60% of the total power consumption isattributed to the Air Conditioning Plant.

To reduce the load on the air conditioning plant, the projecthas installed green mesh outside the west facing balconies,

placed green plants in the balcony, all the windows havesolar lms and are sealed with rubber lining to preventin ltration of air.

Apart from this a Heat Recovery Wheel has been installedto transfer the heat from the incoming air to the outgoingexhaust air. PBC also follows a lot of good practices likecleaning the AHU lters on a daily basis, monitoring andrecording temperatures at all levels on a 24 x 7 basis.

The project has installed sub meters at all strategic locationsin the building in order to track the daily power consumptionand to control any wastage hence, electricity consumption isrecorded twice a day in order to have an effective control on

the daily power consumption.Motion Sensors have been installed in the bathrooms inorder to control electricity wastage.

AT PBC- STIP all General Lighting Solution lamps (GLS)have been replaced by Compact uorescent Lamps (CFL),while maintaining the same lux levels this has resulted in anet saving of 6.04 MW per month.

This initiative has also been extended to the PBC Team thathas also taken the step forward and replaced the GLS lampsat their home with CFL lamps. Assuming that 60 W lampswere replaced by 11W CFL lamps, there was a straightsaving of 49 W thus, resulting in a cumulative saving of approximately 12 MW per month.

This is based on the declaration by each Team member thatthree lamps have been replaced per house and based on vehours of lighting per lamp per day.

PBC - STIP replaced 1,600 old tube lights with 1,200 newTLD true light & electronic ballast while maintaining thelux level as per DIN 5035 standards. This initiative resultedin saving of 9.29 MW per month i.e. a saving of 15 W per Hour per tube light.

As a results of various Energy conservation initiativesthe projects MDI has come down from 735 to 392 KVA

Waste Management Waste is segregated at the point of its generation itself.

The PBC converts food waste into organic naturalmanure through vermiculture with the help of worms.This waste is like a value-added product that improvesthe plants & the environment.

Organic waste management is done through

vermiculture. The manure produced is rich in microbes,humus and plant. All these are available at minimal costand are used for horticulture purpose.

Inorganic waste like paper, aluminum foils, plastic bottles, is recycled.

Water Conservation Rain Water Harvesting:

PBC collects the rain water from the roof and through pipes it goes to an underground tank where the system
