Sustainable Idea – Going Down Under

The last time I went into a cement & glass in-cased tomb called a corporate head-quarter in Mumbai, I remember that no one was looking out of the window.

The reason for that were several

1. Nothing worth viewing 2. Glass was too dirty to be viewed through 3. Files covered half the window for clear sight 4. Curtains were drawn, which had a hint of cob-web indicating that they are never opened.

Although Cement is one of the most carbon-intensive industries and in 2020 will account for as much as 5 Gigatons of CO2 emissions. The manufacturing of glass is also not less energy intensive.

The fact of the matter is building industry the consumer of all that is produced across sectors is the most energy guzzling sector. And finding new ways may perhaps help us avert the calamities to some extent, although the time to avoid the Armageddon is long past.

Therefore coming back to the opening remarks of this article, I propose that the next batch of buildings we build should go vertically underground. There are many simple reasons for this.

We can begin with trying to be a little more resource efficient in this fast resource depleting Planet.

Almost all  the glass ensconced office towers in India are hermetically sealed tomb from which none peep out, or breath the fresh (polluted) air. In the process we draw upon huge amount of energy to cool a  glass building. A glass building in a sunny climate while looking very European or American also acts as a green house in the classical sense. It simply traps the heat and increases the heat surrounding the building by up-to 19%, in case of Mumbai. (NEERI report 2012) – Subterranean Hotel London-Green-Belt

By building underground,(going completely underground although possible; we have examples of defence organizations; would need new science to reduce cost of waste discharge which I am not sure we have  mastered.) the least we could do is cut the cooling needs for  the HVAC and thus also save on water. It would also saving a huge amount of sand, sodium carbonate, calcium oxide, lead oxide, sulphur and sodium sulphate / sodium chloride or antimony oxide  the basic ingredients to make glass.

These materials too need to be mined / extracted / processed which need a lot of energy.  One would be surprised at the mind boggling GHG the above materials produce in there own life-cycle analysis before they help make glass.  2300°C of energy is required to melt the silica to make glass.

Now to look for the second simple reason to go underground.

Selgas Cano Architecture’s Subterranean Work Space

It is a well known fact that Climate change will bring about food crisis, unparalleled in recent history. Therefore must turn to solutions which till now have only been considered as novel ideas. Ideas which have not been practical or possible to accomplish in large scale. Even though examples of such construction is around us within the very modern cities we live.

Imagine having a  HQ deep below while young and earnest farmhands toil away on the roof-top of the building which is situated right at the proposed city centre of the future.

Thus in a single master stroke we could eliminate the plight of the street children and their parents who mostly are landless farmers; at-least in case of India. Moreover cities around the world are facing food shortages as it pushes farmlands away from the city centre in its mad rush to grow bigger and bigger. Roof-top or vertical farming can not achieve the scale of a farmland produce.

Sustainable Homes –

Every-time we build a city, we destroy a village. Along with it the farmlands and natural landscapes. But if we still wish to partially mitigate the effects then we must find ways for both to co-exist. Bio-diversity may well be our last hope to reduce the impact of what is fast approaching.

Coexistence of a City-Village is a must.

We must build more  communities  as the one shown in the image.  Make it mandatory via the UNEP-SBCI for any further development in the still remaining untouched fringes of mega-cities which will get gobbled up by concrete in the next 10 years. This is the perhaps one way through which we can avert the disasters we keep inviting upon ourselves.

Humans always knew how to live in harmony with nature. Somewhere down the line we lost that art. Its time we find it again.

If my readers finds the last image endearing enough for them to think even for a fraction of a second, to wish living in something similar….it proves that Humans are yet to disconnect the umbilical cord from what is Natural.

Business As Usual – a sure-fire guide to kill Sustainable Development Goals.

“Only Rupees Two ?. What about the rent of my roof ? With Mumbai realty prices starting at Rupees 6000/ feet square, I only get to save Rs.2 per KW on my electrical consumption and that too for a measly 20years ? A minimum of Rs 4 should be considered. After all it will be installed on my roof and it makes perfect business sense to bargain for more. After all the investor is doing this for profit and not for charity. It must be business as usual for him.”

With EPC for solar hovering at 8.5 Crore  shaving Rs. 4 out of 10 left us with a number which no investor who is not a buccaneer would touch and no banker would believe in. Especially when the user, does not have to pay a single Paise for the Engineering – Procurement – Construction (EPC) or pay for its Operation & Maintenance (O&M)  of the Solar power plant, but just consume the power produced for the full period of 20 years. And the Return on Investment comes via the tariff the user pays monthly, adjusted over the length of the contract.

In my effort to save the planet from global warming, I was pleasantly surprised when a few RESCO ( renewable energy service company ) approached me with the idea of applying Solar Photovoltaic as an alternate day-time energy source for large commercial establishments. It was like manna from heaven. What more could a practising LEED / GRIHA consultant want ? It would make all my buildings much more “greener” than the other green buildings. It was like a dream come true. Thus I ventured out to increase the ambition of my clients to go for Green Building certification, comforted by the fact that I would accrue more points on the certification scale with use of all that is possible with Solar Power.

Little did I know, that no one would be interested in utilizing such opportunity unless they could bargain for more. It is a typical tendency of all Human today. We always seek more. Even in death we seek more. While our ashes would hardly fill a small Urn, we like to have a few hectare of land as memorial. Everybody wants to build the Taj Mahal; the largest tomb-stone of this planet.

Capitalism and Greed ruled then. It rules now. The only difference is that the Emperor did not have to worry about Global Warming and sinking of the landmass under the sea !

It is therefore imperative that the Business As Usual model changes. Nations must act in unison to delete the present Capitalist meaning of Business as Usual. Simply because we are living in unusual times. This trend is evident even at the UNFCCC meets, which have now become more of a tour operators delight and the host country which wins the next round of meeting, prepares like one does after winning the Olympics, to rake in the moolah that would come from packed hotels; a sure-fire way to end the lean seasons of a city. And the repeated failure to come into concrete agreements since the Copenhagen Summit only lays credence to the alleged fact.

People follow the path shown by their leaders. When industry captains and world leaders apply the fundamentals of capitalism and have through that applications benefited self and the Nation in the past, it is hard for the common man not to practice it in one form or the other. In India, since Independence we have followed and still follow the L1 format. Everything has to be sasta-sunder-majboot ( cheap & best ). That we have a major scam a day and still considered 3rd world proves that we are wrong and horribly so. A few shiny glass buildings in 4 metropolis does not change the facts. All an unbeliever needs to do, is come to Mumbai and while staying in any tall-building wish not to spot slum & squalor. His/her prayers would not be answered.

It is therefore necessary for the leaders to take the responsibility of preaching the SREX Report and also the (IWR) Inclusive Wealth Report in our collective bid to forward the Sustainable Development Goals. (SDG)

Millennium Development Goals Postcards

The Eight paths towards the Millennium Development Goals (MDG)

  1. Eradicating extreme poverty and hunger,
  2. Achieving universal primary education,
  3. Promoting gender equality and empowering women,
  4. Reducing child mortality rates,
  5. Improving maternal health,
  6. Combating HIV/AIDS, malaria, and other diseases,
  7. Ensuring environmental sustainability, and
  8. Developing a global partnership for development

Which one can achieve by applying the SDG’s charter

  • Action-oriented
  • Concise
  • Easy to communicate
  • Limited in number
  • Aspirational
  • Global in nature
  • Universally applicable to all countries while taking into account different national realities, capacities and levels of development and respecting national policies and priorities.

Till now MDG has hardly percolated to the leaves just below the bud, forget reaching the grass-root.

The way I understand it, the Goal – Ensuring Environmental Sustainability should be the first and foremost focus. It needs to be action oriented and not conference oriented. Because conference by default don’t help in communicating easily. It is meant for the class not mass. And the class already aware of the subject are achieving almost everything as envisioned as long as it serves their narrow interest . It is the pace which is hardly comforting even if one accounts for the narrow interest oriented improvements the agenda of the rich promote.

How difficult would it be for the United Nations, to communicate directly to millions of internet users on a sustained basis and engage them on an one-to-one conversation to partake in Sustainable practice? Which directly benefit them, and thus allow them to make informed choices. How difficult is it that the World leaders come together and de-link the process of sustainable living and its practical methods from the BAU model as practised in the present flawed market system ? Why should the IRR (internal rate of return) and RoI (return on investment) be calculated based on a flawed capitalist system where profit always means self aggrandisement?

Why cant the World Bank and Economists innovate the datum through which sustainable tools and its products get measured for its RoI against the IWR ?

The logic is as follows. Should say, the Government of India decide that following MDG goal # 7 – all Buildings, Factories and Commercial  establishments opt for Renewable energy, as viable depending on the location, these are perhaps a few things that is bound to happen.

A) As the power consumption through fossil fuel would reduce, the pressure on the exchequer too would reduce. This is because we can import less oil. Now with the saved petro-dollars the government can implement all the social up-liftment programmes namely MDG goal 1; 2; 4; 5 & 6.

B) Large Hydle-powered dams would not be needed to be built any more and the lush green ecosystem which along with a few hundred villages, and with it the future of villagers would not have to sink into oblivion. This would directly save many from abject poverty and migration to cities to increase the size of slums. In fact the villagers could benefit by having some electricity themselves and improve their lot as mentioned in my earlier article Green Building Ideas:Using Solar panels as roofing sheet instead of asbestos. while the government benefits further.

C) While promoting gender equality requires the discipline and sobriety fast disappearing from our political class, as evident from the comments they have given on media in recent and not so recent incidents of crime against women. Empowering women can also be possible through use of RE, a few ideas on them can be found in my article Renewable Energy – Empowering Women & Saving Forests.And through this too, as explained in the article the government can save on cross-subsidy and full-fill its promises for uplifting its countrymen.

It is business as usual for one political party not to allow an individual politician form a competing party to implement a good idea, which has mass appeal. Simply because in the next round of election the statesman may win against the politician.

Perhaps at the end of 1000 days in 2015, we will know whether we really achieved what was envisaged in the MDG or we still have to look beyond for the Future We Want.

Green Business Ideas: Carbon Credits opportunities in Green Townships.

Most women & men have an emotional connect with the home they have lived as a child. In India families often live their entire life in one abode for generations. Even as India grows from its rural to more urban setting, the people still like to retain their “ancestral” home while moving into the swanky new home. There are some emotions which no one likes to part with; and childhood memories are perhaps the most important.

Perhaps many around the world  would share similar sentiments. Some want to make a retirement home, some would want a second home. Given a choice nearly every human would want to identify her/himself with something that is familiar.

This gives rise to a super Green Business Idea, which has manifold potential in rescuing Gaia from Global Warming.What if, future towns and cities are made as replicas ? Modern India has done that and, unfortunately forgotten about it. Cities like Rourkela, Bokaro, Durgapur & Bhilai which have almost similar design created by the master architect. If one pauses to think we have in almost all large cities, the state / city development authority housing board, which make ” affordable ” housing blocks. The typology remains the same over different locations. I think its time for a revisit and see it with new light in the context of abatement of climate change. Imagine High rises, commercial districts, row-houses and bungalows all having same or similar design ? Developed by private entities based on market demand, but following Development Rules which have been strictly adhered to. What would be the advantages, lets examine  in brief and re-kindle the thoughts which are perhaps lost in time.

The most exciting part is the CDM ( clean development mechanism ) potential. Every building has potentially two methods for adoption, to earn Carbon Credits. One is to reduce its embodied energy through better management of building materials. And the other is to reduce its Water and Electrical energy consumption. While the latter is comparatively easy and ‘meth’ AMS-III AE is recognised by the CDM Board. It is the embodied energy reduction that  has greater potential in terms of actually reducing GHG  as building related activities account for 40% of the Emission and 60% of waste is construction related.  However it is difficult to map it  and manage the MRV.( Monitoring – Reporting -Verification.) especially in the Building industry within the Construction sector in India. And this is precisely where I see a solution, should we make ‘replica townships’. We already have the datum to compare. The planned steel townships were made just after Indian independence. It has as any township should have – residential blocks, commercial blocks and infrastructural blocks such as schools, hospitals, cinemas,  police station, post-office , bus and railway terminals. So a major portion of the township plans would be available along with records of construction process; which would be archaic as per today’s construction methods (barring the A- centres of India, tier -II & III along with most rural setting still follow the old method of construction) but the layout plan is excellent. So with foresight and statesmanship, ( wishful thinking does not attract punitive punishment under any law ) should the Indian government both at Union and State level want to pursue its own stated Nation Mission for Sustainable Habitat under NAPCC; they should pass laws under Urban Planning which can make this thought into reality. As the Union government has already created the fantastic Mission, all it needs is to rise above political compulsions and address the issues at the Federal level, by becoming the facilitator in creating sound policies for the States, which then follows the path towards sustainable development.  And the benefits would be several.

First the  Urban Planning will be made easy – The biggest challenge the Urban planners face is the assumptions one needs to take into account, while proposing a new township. What would be the population density? What would be  the amount of water and energy requirement ? How will the municipal requirements met?  How best to accurately calculate cost of development. Where-all would the failure of oversight be, causing unplanned growth or breed corruption? Because post the master layout plan, the State development authority has no control { which is correct to an extent } over what would be the look and size of the building which would come up within the designated zone of the master plan. All such issues would become more streamlined and thus decision making more easy as the learning process gets more refined with each replica township coming up every-time.

The master-plan need not be a monotonous one. India has 5 – climatic conditions and design guidelines based on these are already incorporated in the National Green Building certification program – GRIHA. Therefore Master planners can create guidelines which conform to region and state specifically. However, within that area the designs can remain similar. Further, the best practices followed in other climatic zones and states would be available for record to plan better Climate Resilient cities, which is the underlying purpose of this article too. Imagine the potential, should a developer choose three typical design and develop different projects, in 3 different cities within one climatic zone. While the town-planing would differ in layout and scale, the buildings built therein being the same, would reduce cost of construction to a great extent. Design inputs required would reduce, while scope of improvement increase with every project thus designed. As every project has some amount of wastage, knowing the quantity to a more sure approximation, would help in planning for Reduce – Reuse -Recycle as enshrined within the Green Building methods both LEED & GRIHA.

Further a brand identity would be built. A building design can be copy-righted so to speak. And what an emotional connect it would be for the newly wed Bride, who has sadness in her heart for having left her ‘Babul ka aangan’,(fathers home) finds that her ‘Pia’ (husband) has the same bungalow she grew up in. Familiar setting instils confidence and a confident and happy new Bride can do wonders in settling herself well into the new life, she would be beginning.  That it would earn the builder/developer a permanent costumer (extremely difficult in this era of multiple choices), is another happy story. And if we speak of men,  I’m a member of an on-line group which was created by my childhood school mates and friends. We all lived in a gated township of a multinational company, where our fathers worked. Today of the 300 odd members, 51% would surely buy a home, should I design the replica of the town we all grew up in !

And the final winner would be my Countrymen, most are laymen when it comes to understand the importance of town-planning and Sustainable Urban development.  By providing them with standardized product, they would have more informed choice to take the right decision, as they do while buying their refrigerator or car. And most importantly it perhaps would become easier to decongest the future Megalopolis. For why would one not move into a newer town for better prospects while still be able to live within similar surroundings ? And why would people migrate to a particular city when similar ones are next door offering similar opportunities ?

And the final thought would be, the Urban planners should consider bio-mimiciry in their town planning. As technology would allow us to make higher sky-scrapers, rules must define low rise zones to be closer to coast and high rise more inland, this simple thought would allow for more natural wind flow pattern, which will help limiting air  pollution.

While no one can make another New York, Hong Kong  or Mumbai in similar form, potential or opportunities the new ones at least would have a future of their own making and who knows better the best that is in offer today.

Moreover Climate Resilient Cities which I am proposing would be offering a more prettier skyline than what any present day modern megalopolis has to offer. To underscore my point, which from all the above images posted in this article would you choose first for a postcard ?

I rest my argument !

Green Business Ideas : Tall Buildings made from waste plastic is possible & its LCA is cheap – a builders delight and boon to Environmentalist

Business all over, in every Country is in flux. The fine tuning between Economic growth with least Environmental damage, while maintaining the modern life-style is challenging to say the least. But it is precisely during these challenging times, the World should go back and re-look at inventions – ignored during the ‘gold rush’ days in every sphere and bring forth into light others which are perhaps thriving in isolated pockets, but need the urgent attention to be brought out into the limelight and popularize it among the masses.

Thermo Polymerized Rock;  I did not even have the slightest idea that when I would sit down to write this article, every thing I would be asking the Green Building councils around the World to mull over, is already a ‘ open packet and serve’ solution. Affresol Modular Buildings are made from an innovative new structural product called TPR™ (Thermo Polymerized Rock).  It can be used to make the “Modular Buildings” and “Sectional House Frames” which have a Compressive Strength range 22 KN/mm2 to 38 KN/mm2. And perhaps there would be many more companies around the world doing the same. Its their time now. In India we have a Company Damanganga, which manufactures roofing and flooring sheets from waste, even some furniture, but I have not yet met a company which is making product like TPR.  Yes! the common people in the streets must know about it, not the intelligentsia discussing it in Five Star Hotel seminars.

BASIC countries (red) and other G20 countries ...

Image via Wikipedia

And if discussion indeed need to happen then it should be on how Tall Buildings in Asia can be made modular. And more so in the ever growing cities of South East Asia. Every one knows that in this economic gloom and doom period, the rising stars are the BASIC countries. India being one of them, would be having a revised projected growth of 5% to 6%  instead of 9%. And according to the Deputy Governor of the Reserve Bank of India, this can by no stretch of imagination be called ‘recession’; slower growth maybe. Therefore The European Union which is facing an economic crisis can harbinger overall growth by exporting their technology and expertise on TPR, help stave plastic pollution and earn some goodwill along with money. It could be the beginning of a great green business idea.

Because, as the South East Asian Cities grow, they bring with them problems, many of which have been addressed in my earlier articles (; ). Mumbai and New Delhi both are signatories of C40 Cities program. In fact all over cities are looking to become Climate responsive. In this back drop, it would be one of the finest engineering goals for the Construction industry to devise about how Tall buildings in India can be built with TPR.

Imagine – 50 years down the line, all one has to do is dismantle section by section a whole sky scraper  and pack it of for recycling. No construction debris, no brown-field sites filled with plastic. Having popularized the method, one can just start mapping the embodied energy saved, from limiting the use of cement  & concrete, paint and other conventional building materials. Also, the basic being plastic, one can have thinner walls which are both sound proof as well as lighter in weight. This would surely reduce the structural steel and make more carpet area  to wall space  ratio .

A winner in every way, for now each plastic bag, article which was discarded without a thought would be a valuable article to be segregated and sold. Perhaps enterprising companies would trawl the ocean floors near the countless beaches and gather the plastics which as of now are cause of Environmental hazard!

Technical Manual for Sustainable Site Documentation.


The purpose of sustainable site planning is to integrate design and construction strategies by modifying both site and building to achieve greater human comfort and operational efficiencies. It charts appropriate patterns of use for a site while incorporating construction methods that minimize site disruption and the expenditure of financial and building resources. The process is based upon the premise that any landscape setting can be analyzed and studied as a series of interconnected geological, hydrological, topographic, ecological, climatological, and cultural features and systems. Selecting a building site begins the process of calculating the degree of resource use and the degree of disturbance of existing natural systems that will be required to support a building’s development.


Site assessment is a process that examines the data gathered and identified in the site analysis, assigns specific site factors to hierarchies of importance, and identifies, where possible, interactive relationships.

Data collection:

Technical site data –

Geographical latitude (solar altitude) and microclimate factors, such as wind loads

Affect building layout, including solar orientation and location of entrances, windows.

Topography and adjacent landforms—Influence building proportions, wind loads, drainage strategies, floor elevations, and key gravity-fed sewer-line corridors.

Groundwater and surface runoff characteristics— determine building locations as well as natural channels for diverting storm runoff and locations of runoff detention ponds

Solar access—Determines position of building to take maximum advantage of natural solar resources for passive solar heating, day lighting, and photo voltaic.

Ai r-movement patterns, both annual and diurnal— particularly influence sitting of multiple structures to avoid damming cold moisture-laden air, or blocking favorable cooling breezes during periods of overheating. Properly measured wind loads and pressure differentials are essential for designing interior air-handling systems or use of passive solar cooling strategies.

Soil texture and its load-bearing capacity—Determine building location on the site and the type of footing required. Identify site-grading processes by the soil’s potential for erosion by wind, water, and machine disturbance.

Parcel shape and access—Affect a site’s capacity to accommodate a proposed development, even if its size and environmental\ factors are favorable. Potential access points should not burden lower-density or less compatible adjacent land use. Zoning setbacks and easements can also affect development potential.

 Neighboring developments and proposed future developments—Affect proposed project and may lead to requisite design changes.

Analyze specific characteristics of climate zones: Climate has specific characteristics requiring mitigation, augmentation, and exploitation; there are 5 climatic zones in India.

Analyze the site’s existing air quality: Most state require an environmental impact assessment (EIA) outlining the potential negative impacts of a proposed development and how they might be alleviated. Site planning requires two kinds of air-quality analysis regarding: (1) assessment of the existing air quality of the site to determine the presence of noxious chemicals and suspended particulates, and (2) projection of the negative consequences (if any) of the proposed development on existing air quality. In primarily commercial or industrial areas, poor air quality should be a key factor in determining site suitability and use, especially for such facilities as schools, parks, or housing for seniors. Testing should anticipate seasonal or diurnal wind patterns to make certain that the worst possible case is tested.

Perform soil and groundwater testing: Perform soil tests to identify the presence of chemical residues from past agricultural activities (arsenic, pesticides, and lead); past industrial activities (dumps, heavy metals, carcinogenic compounds and minerals, and hydrocarbons); and any other possible contamination either on or in the vicinity of the subject site.

Test soil suitability for backfills, slope structures, infiltration: The native soil should be tested to determine bearing, compactability, and infiltration rates, and, in turn, structural suitability and the best method for mechanical compaction (i.e., clay soils require non-vibrating compaction and non-erosive angles of repose for cut-and-fill slopes).

Evaluate site ecosystem for existence of wetlands and endangered species: Preservation and restoration strategies require thorough economic analysis, specialized expertise, and sound baseline data gathered through both remote and on-site sensing methods.

Examine existing vegetation to inventory significant plant populations: This will enable the developer or owner to later specify vegetation that is susceptible to damage during construction, so that protective measures can be developed and implemented.

Map all natural hazard potentials (such as winds, floods, and mudslides):Eberhard Bosslet - Since 1983 - works with rui... Historic flood data, wind-damage data, and subsidence data should be mapped along with current annual wind and precipitation data.

Diagram existing pedestrian and vehicular movement and parking to identify Patterns: Existing traffic and parking patterns in areas which are adjacent to or near the site may need consideration in relation to proposed building design and site circulation patterns.

Review the potential of utilizing existing local transportation resources: Explore the sharing of existing transportation facilities and other resources, such as parking and shuttles, with existing institutions. This can lead to greater site efficiencies.

Identify construction restraints and requirements: Special construction methods may be required because of local soil condition, geology, earth-moving constraints, and other site-specific factors and constraints.

Infrastructural data

Analyze site for existing utility and transportation infrastructure and capacity: Existing infrastructure should be analyzed for integration into the building and facilities.

Historical Data

Review architectural style of the area for incorporation into building: If desirable, the architectural style that is historically predominant in an area can be reflected in the building and landscape design, enhancing community integration.

DATA ASSESSMENT  Illustration of a level spreader installation ...

Identify topographic and hydrological impacts of proposed design and building use: Measure cut-and-fill potential and assess potential for erosion, siltation, and groundwater pollution.

Develop general area takeoff and overall building footprint compatibility with site: For example, measure total site coverage of impermeable surfaces to determine thresholds of run-off pollution potential (i.e., over 20 percent impermeable coverage of gross site requires mitigation to clean storm water before it enters drainage system off-site). Footprint should also maximize site efficiencies with regard to required road, utility, and service access.

Identify alternative site design concepts to minimize resource costs and disruption: Develop several alternatives to explore optimal pattern with regard to factors such as grading and tree-clearing consequences and resulting infrastructure costs.

Review financial implications of site development, building, and projected maintenance costs: Total cost of the project must factor in ongoing costs associated with the site design, development, and operations, as well as hidden embodied energy costs associated with specific materials.

DeveloUS Air Quality Index Map-1/23/2009p matrix of use and site compatibility index: Each site may be assessed to reveal its development compatibility index with regard to a specific type of development. This index may reveal a pattern of incompatibilities thereby specific appropriate mitigation measures are undertaken.

Carbon Credit in Green Buildings

United Nations Framework Convention on Climate...

Carbon Credits are generated by enterprises in the developing world that shift to cleaner technologies and thereby save on energy consumption, consequently reducing their green house gas emissions. For each ton of carbon dioxide (major GHG) emission avoided, the entity can get a carbon emission certificate which they can sell either immediately or through a futures market, just like any other commodity. The certificates are sold to entities in rich countries, like power utilities, which have emission reduction targets to achieve and find it cheaper to buy ‘offsetting’ certificates rather than do a clean-up in their own backyard. This trade is carried out under an UN-mandated international convention on climate change to help rich countries reduce their emissions.

There is a great need to reduce energy consumption in all sectors of the economy. Building Construction consumes vast natural resources, and building account for 40% of Global Energy use. The pre-construction phase is the optimal time to implement Energy Efficient design with minimal costs. Some results indicate that savings realized during the first twenty years of operation can account for more than 15% of construction costs.

The above paragraphs sums up in brief the basics of this discussion. The first one is the need to build Energy Efficient Buildings ( EEB‘s ) and the second to find the additional expense. Every one knows that to build an EEB one has to spend more than normal. Now the idea is how to get back the additional money spent.

Both in GRIHA  & LEED  the return on the investment is proven over time on various projects Pan India. However most of the data I have seen point to Institutional or Commercial  or Corporate projects. It is comparatively easy to map and maintain year on year energy reduction of buildings where the user would normally conform to the same pattern of use and adhere to the building maintenance and use guidelines  stipulated by the owner.

Moreover it is comparatively easy to explain prospective Corporate or Commercial clients wanting to do a Green Building the advantages and returns as mostly it would be for self use and benefits accrued are directly debited to them. The difficulty lies however in convincing the Builder / Developer who by default would make a core & shell edifice and sell it. This format is true for both residential & commercial projects they undertake. So explaining this group to go for EEB is a little difficult. This does not discount the fact that almost all big and reputed builder developers are already adopting Green Building norms and getting their projects certified in one rating or the other. In India both GRIHA     ( Green Building for Integrated Habitat Assessment ) the National Green building rating system and the CII led IGBC – LEED Certification are prevalent.

The Indian Green Building Council guided and supported by the Confederation of Indian Industries has a larger building foot print  under their rating system than GRIHA as of today. Under IGBC a continuously evolving and user participation based organization, which is quick to understand the business opportunities in sustainable practice has under its command a host of rating systems for different typology and yet for the common good of reducing Global warming & abatement of Climate change. Certification & Rating such as LEED -India CS, LEED -India NC, IGBC – Green Homes, IGBC – Green Township, IGBC – Green Factories and the latest being IGBC -Green CO.

What I have been proposing is using this brilliant rating system for large projects called ” Green Township”   map the reduction in energy and apply the existing methodology approved by the United Nations Framework Convention on Climate Change ( UNFCCC ) for earning Carbon Credit. This money which one can earn through Carbon credit would not be sufficient to make profit, Carbon fund can be availed only by proving “additionality” which means the project must have incurred expense by which profit is diminished when compared to a base case;but it has been designed in such a way that it would definitely help offset part of the cost of going “Green”. I know I can do it and I propose other architects to do the same for builder/developers. In this manner we as professionals will be able to provide true value sustainable habitats for our country.

There are two methods by which one can earn Carbon Credits in Green Buildings. The first is mapping the reduction of materials used which is done when a building goes through the rating process; as each material has its own embodied energy, the reduction in its use would thereby help reduce the GHG emission. This however is quite difficult because the MRV (monitoring,  reporting and verification) process would be very cumbersome especially when applied to the way the construction process is in India. It could leave too many gaps which require careful thought and stringent process to be absolutely sure that the method applied is sound both academically and practically.

The next process is to map the reduction in electrical energy and water consumption.  This is a simpler method and use of RE which already has proven methodology helps getting the CDM process. As India is encouraging Solar Photo voltaic, both  roof-top or “green-power” wheeled from off-site location would qualify to earn Carbon Credits.

Green Certification for Interior Design

Logo of the World Green Building Council, whic...

World Green Building Council

A lot is being done in the field of Green Building. New rating systems are coming up around the world. What started out as LEED– US, spread to LEED -Canada, LEED –India {IGBC} etcetera, today we have a World Green Building Council. The UK has its BREEAM, Australia & New Zealand have their own rating, Singapore and the far east also rate their buildings.

India also has a rating system designed under the command of the Government of India, the GRIHA. Showing India to be a very progressive and mature Nation with regards to its understanding & supporting the cause for abatement of Global warming.

But while, including LEED-India & GRIHA  rating give importance to Architectural / Civil- Structural efficiency along with Lighting & HVAC energy reduction in their quest for rating the building for its “greenness”  not much is being said about the interior design. Other than in LEED -US, which has a commercial interior rating called LEED-CI but that is all there is, according to my knowledge. I may stand corrected in this and would be happy to know of any other green interior rating.

The reason Interior Design,  a very very big and lucrative market World over; does not have a stand-alone Green rating of its own is because most of the existing  “Green” ratings presume that the subject gets automatically dealt with when one does a “Green Building”.

Well this presumption is correct to an extent, such as in selection of bath  & toilet fixtures which generally conform to the requirements stipulated for water efficiency, to recycled tiles, certified wood, low-V.O.C paints, LED lighting, low SRI carpets, star rated A/c etcetera. But for me, this should not be the case. I don’t see this as a complete solution at all.

Now lets see how much of it gets done in India. Not much to speak of !

Both LEED-India & GRIHA are in there early years, the knowledge and idea about them amongst the Building & Construction Industry is very limited, pan India. A few good developer/ builder do practice it. However, most have rudimentary to nil knowledge.

With this being the situation when it comes to construction of “Green” Building, I would rather call them Energy Efficient Building {EEB} to avoid any confusion as to the purpose and intent; it is hardly surprising that we do not as yet have a rating system which will cater specifically to interiors.

Yet every day we have some high-end show room opening which displays furniture, wall & floor tiles, Italian marble & granite, Egyptian carpet and et al. Do these furniture & tapestries with there high -gloss and stain free coating get checked for there Environmental friendly approach?

Don’t  the teeming, so called high end and those who aspire to be high-end Interior Design Consultants, who rip apart perfectly well done interior finishes in the houses of the rich & the famous and toss out every inch of wood -work, stone, highly toxic paints scraped from walls etcetera, need to be aware?

Aware that their actions are detrimental to the planet? Should not they also be educated on the mantra of Reduce – Recycle – Reuse? The three “R” are the basic principals of a “Green” or to be exact an Energy Efficient and Sustainable design.

It would in my opinion make immense Economical & Ecological sense if both IGBC and ADaRSH  the  Indian institutions responsible for the LEED-India and GRIHA rating system start to think about creating a – Green Interior Rating which can rate both commercial & residential projects.

India would be left richer as a sustainable Nation should awareness in Green Interiors is mooted. As one must remember homes & office premises are usually bought once in a life-time of most Indians but Interior design usually happens once in 5 years; either at one go or in instalments most Indian homes see this change.

It is time we think of doing something right about it and make the world a little more safer for our children.
