BCIL raises Rs 900 million to fuel growth

Rupees-symbolIn a major breakthrough, BCIL has signed a deal closure for Rs 900 million from a large Bombay-based funding institution. The transaction is a combination of funding in the two premium BCIL projects exceeding over 1 million sft between Bangalore and Chennai.

This is the first major fund that the green major has accepted after establishing itself as an undisputed leader in energy-efficient buildings.

ZedEarth in Bangalore is a half- million sft. development that cuts fresh water demand by 70 per cent, uses no borewells and cuts energy demand also by 60 per cent with a combination of demand-side and innovative supply-side solutions.

ZedRia in Chennai offers over 600,000 sft of similar zero energy developed homes with no dependence on external water supply and sewerage board.

Energy and water harvesting and urban agriculture are unique to each of these zero energy developments. Both projects are under way and will offer a total of nearly 1,000 homes over the next 1 to 3 years.

For gridless power at home or office.

Solar installation at a ZED home

Just the 5 star geysers refrigerators and AC’s in India are saving about 9000 MW of power generation every day. India produces 220,000 MW. Government has cleared 80,000 more MW. And they want to raise this to 700,000 MW. Where’s the coal? India is creating 3 nuclear plants when Germany and Japan have closed all their N plants after 20 years. Coal mines destroy lives, livelihoods, forests and rivers.

Actual end-use power used is a mere 30,000 MW, if local power from solar and wind is not fed to grid but used directly by homes, offices, factories, hotels and hospitals.

The power industry lobby fears loss of the massive business if local power is promoted. Governments don’t want to lose the opportunity big spending offers of making speed money.

A solar station costs no more than 4-10 lakhs at about 2 lakhs to a KW of quality generation. It saves money on Gen-sets and UPS. Diesel power costs Rs. 20 a unit. UPS cost over 2 years with battery replacement Rs. 14 a unit. Solar costs Rs. 13 a unit, with the catch that you’ve to invest, not the government. Your BESCOM tariff is 7 to 14 a unit depending on user category.

IS YOUR FURNITURE SPREADING POISON IN YOUR HOME?

DSCN3746Formaldehyde is a chemical that can cause serious health damage. It is present in disguise within our homes and usually goes unnoticed. The most significant source of formaldehyde is the pressed wood products that use urea and formaldehyde resins as adhesives. These products generally include particleboard, hardwood-plywood and fiberboard.

Particleboard is used for sub-flooring and shelving in cabinets and furniture.  Hardwood-plywood is used for decorative wall coverings and fiberboard is used for drawer fronts and furniture tops. Fiberboards are significantly higher in formaldehyde emissions than particleboard or hardwood.

This toxic chemical is generally used as a preservative in labs and can lead to serious health problems especially for kids. Cribs, cots and other furniture can release up to 40 parts per billion of formaldehyde per day — enough to cause illnesses like asthma, allergies and even increase the risk of cancer.

People move to greener spaces with a notion of providing healthy living conditions to their families but fail to take care of the smaller aspects, such as formaldehyde emissions, that can pose larger health hazards.

A study shows that formaldehyde emissions in a newly constructed apartment had as much as 23 parts per billion per day of formaldehyde even before the furnishings were installed. This is a staggering 8395 x 10-9 part per billion per year. Imagine that amount of toxicity in your house which is a large part of your indoor environment.

So how do we overcome this? The answer to this lies in the use of furnishings that are free of such toxic chemicals and made with recycled materials that require little or no formaldehyde-based adhesives. Manufacturers like ZED have brought in a range of furniture that is forest-free and use no formaldehyde and so offer zero emission furniture.

Who doesn’t want a healthy life? But how many of us do what it takes to ensure such well-being, for not just one but many generations to come?

It is time now to adopt a chemical-free, toxin-free lifestyle before it is too late to realize.

Are your plants getting the right amount of water?

watering-can-old-manTending to a garden is a liberating experience and lets you bring out the eco-philic side of you. Although looking after a garden is not rocket science, care must be given to all aspects to ensure your plants look healthy and fresh. One such aspect that is generally overlooked by most of us is watering the plants. Although it appears to be a simple activity, it is in fact one of the most misinterpreted, often with disastrous consequences for the plant. When understood and carried out properly, it is capable of significantly influencing the relationship with the garden.

So let’s start at the very beginning. While we say “we’re watering the plants”, we don’t water plants, we actually water the soil.

Yes, that’s right. Plants take in their required amount of water from the soil so watering the soil around the root zone (away from the stem) is most beneficial to the soil micro-organisms, and therefore the plant.

Equally critical is knowing that plants need moist soil rather than wet or submerged soil. Moist soil enables the water to break down necessary components in the soil into a small enough size to be absorbed through the plant’s root system. Over watering can lead to loss of nutrients and minerals and also decrease aeration.

Plants should be watered early in the morning and not late in the evening. Plant diseases are known to spread in wet, dark conditions and when we water in the late evening, water tends to stay on the leaves, making the plant more susceptible to catch mildew (a fungal disease). In daytime, if water does get on the leaves, it has a chance to dry out in the sunlight. Also, plants need water mainly during daylight to produce food, so watering early morning would ensure that they are able to carry out their activity.

Gardens are completely dependent on our watering and so it needs to be planned and regular. Erratic watering stresses the plants. Allowing the soil to dry out completely between watering is not a good idea and works only for specific plants. Most plants require consistently moist soil conditions.

How do you water plants?

For an urban home garden, there are several ways to water from the simple bucket and mug or rose-can (can with a shower-head nozzle) to the more planned drip irrigation mechanism.

Adopt a method that is best suited for you and one that does not waste water. As far as possible, try to harvest rainwater. Reuse grey water – i.e. water used for washing clothes or vessels for use in the garden. But remember this is only if we avoid synthetic detergents and use natural alternatives or other powders.

Mulched soil has greater water retention capacity and also provides nutrients. It is best suited for a garden. If you have a rooftop garden, ensure windbreaks to prevent uprooting of plants.

Paying attention to the health of the soil is the most important aspect of a plant’s health. Ensuring a well-proportioned mix of sand, red earth, compost and soil-building material (like cocopeat) is essential to make the soil loose, porous and to increase its water retention capacity.

The needs of each plant are different and so plan your gardening activity accordingly taking care of each plant to have a healthy and lively garden.

WHERE’S MY WATER?

WaterBangalore is largely dependent on groundwater. The largest source of water in Bangalore apart from Cauvery water is from borewells.

We are pulling water that has been down there for hundreds of years, that is somebody else’s right as much as it is ours. And the breach of this right can be clearly seen with unequal resource allocation.

How do we get Ground water?

We all live above spaces between soil particles and cracks, fissures and faults in the rocks, which are known as aquifers. Water in these aquifers is rainwater that has trickled down and percolated into the earth. The aquifers are spread independent of property or administrative boundaries. Each time we pull out water from the ground, we are possibly denying someone else of their source of water.

The geology of Bangalore, and most of the Deccan plateau, is hard-rock geology. This type of geological setting is composed of three layers- the top soil where the plants grow, the weathered zone below the top soil and the hard rock. The weathered zone is actually crushed version of the hard rock which holds water in the pores and spaces in between the particles.

When it rains and water percolates down, it passes through the weathered zone and then into the hard rock fissures. A large connected set of fissures, in effect one single body of water under the ground, is called an aquifer. Aquifers in the hard rock are called ‘confined aquifers’ as they are under pressure. Water in the weathered zone is shallow and is referred to as shallow unconfined aquifer and they can travel laterally into the soil. Open wells up to depths of around 80 feet in Bangalore were meant to access water in the shallow unconfined aquifers. Over time these have been dried out, except in certain parts of Bangalore. After open wells started drying, people started digging borewells which were going deeper and picking up water from the fissures in rocks – or from confined aquifers. It is important to note that confined aquifers take more time to recharge the unconfined aquifers.

It’s difficult to predict where you get water in deeper confined aquifers.  At depths of 100 to 650 feet, there are a lot of fissures through which water trickles in. There is no way to predict, other than testing each site.

When you dig a borewell and start pulling water out, you are emptying the water in the aquifers which is a finite amount. The process by which water enters into these fissures is called recharge. This can be natural or artificial. Since there is only a finite amount of water underneath, we cannot endlessly keep pumping out water.

As a city, we need to understand how much water is available. This is not an easy task. All the residents in an area need to share where they have dug the bore well, how deep did it go, at what depth did they get water, etc. The data collected across the city can help get a better picture of the city’s aquifers.

Waste not, want not By Dr. Chandrashekar Hariharan

A green home doesn’t only mean eco-friendly construction, it means an efficient space that reduces dependence on government infrastructure for water, energy and waste

Waste not, want not

 Let’s first make the distinction, for the sake of convenience and clarity, between an ecologically sustainable home and a green home. The former is something that you build with materials that make for the least use of exhaustible natural resources — a typical farmer’s house is the best example, with a combination of clay walls, cowdung surfaces, thatch roofs, limestone-coated walls. There have been homes in the urban context that have attempted to use some ‘traditional’ elements but not always with success on reducing use of natural resources.
What is labelled in current times as a ‘green home’ is what you ‘architect’ and ‘engineer’ in terms of solutions for a regular urban home, taking into account use of building materials for floors, walls, roofs and windows, the use of systems and technologies that reduce consumption of water and energy without compromising comfort or convenience the way you define them as a dweller. If you are willing to spend a little more as capital cost at the start, you can secure savings into the future that can help you recoup your additional capital cost over five to seven or 10 years, depending on what the feature is that you are adding to your ‘green home’.

Green homes can help you save as much 30 to 50 per cent in your energy bills. With the right elements in place, you can rely less on fresh water and therefore increase water security. Beyond such savings, green homes can help you generate some wealth from waste, by managing its conversion into either manure or compost, or even energy for your kitchen. The important thing is that a ‘green home’ in the urban context will help and enable you to reduce your dependence on government infrastructure for water, energy and waste.

The current green market for buildings is focusing on rainwater harvesting for every building, waste water treatment plants that offer 100 per cent recycled water for use, and introducing energy efficiency in the use of pumps and heavy-duty electrical equipment in buildings.

Builders should take practical positions. They should not adopt a textbook approach to sustainability. It has to be replicable, and sometimes scalable. We address the low-hanging fruits that are easier to pick both on demand-side and supply-side management of aspects of water, energy, waste: rainwater harvesting, solar water heating, ‘Grow Our Own Water’ plans that ensure independence from municipal water supply, use deep aquifer water, natural air-conditioning systems are a few examples of such strategic approaches.

We should look for upstream carbon-effectiveness — use of non-river sand based concrete, triple blend concrete, lighter building blocks, debris used for road subgrades, optimising structural inputs for framed structures, establishing micro-climate right at the stage of design and not as an afterthought…. the list is truly long.

The vision is simple: every building must drop demand for freshwater by 40 per cent by voluntary compliance, or by law. The same holds good for power. We should have a drop in demand by at least 40 per cent, with investments made by the building industry for energy generation on their own without dependence on the grid for such local power. All industries should reduce their demand by a minimum 40 per cent for power from governments and local bodies. And they should voluntarily install recharge wells for every borewell that draws from deep aquifers.

Governments don’t offer solutions that are creative. They destroy resources that have been built by earth over many thousand millennia — indiscriminate extraction is only one example of such acts. Governments, as they are structured in India, are simply not equipped to offer solutions into this future before us for these resources and their sensitive management.

At the core, there is only one challenge: consumer behaviour and human behaviour. Can this change? We must not just buy what we need, we have to “buy into” what we need. This means that we as citizens who can afford a certain lifestyle, must bring unto ourselves the joy of responsible buying, and consuming. We have to realise that less than 10 per cent of India’s and the world’s population actually consumes 80 per cent of the world’s natural resources. The poor do not have the money to fulfill their want to consume — not that their aspirations are any different from those of the urban rich. So the single challenge is in bringing about this joy of responsible buying and knowing the significance of what we are buying into.

However, there’s a silver lining. Over just the last four years, the 12-year-old CII Indian Green Building Council alone has managed to certify over 500 million sq ft of commercial spaces. This figure is set to touch the one billion mark (for commercial buildings alone) by 2015. This is because of the clear advantage that commercial builders see in sharp reduction [over 30 per cent] in post-occupancy costs of such green buildings. This is a major draw among B2B tenants that such buildings attract as clients.

The performance has been even more encouraging on the residential sector front, with over 800 million sq ft of IGBC-green-rated buildings coming up across India. Between the GOI’s GRIHA certification and the Pune-based EcoHousing Rating System, there is another 100 million sq ft of such residential and commercial buildings that have been certified over the same period of four years. The downside is that this accounts for less than two per cent of the entire building/construction industry total footprint of buildings in India. There is a very long way to go.

The green market for home appliances and consumer durables is going to see a major and dramatic shift in the near future. All air-conditioners in the Indian and the world market will shift to inverter-based ACs, which will drop energy consumption by 30 to 70 per cent! The current market for ACs is at about 3-3.5 million per annum. This is set to rise to 6.5 million by 2015. The drop in energy demand therefore will be significant in the decade ahead. Wireless energy — like wireless telephony that came in the mid-90s — is the next big game-changer in green development.
If you step back to discern the longer-term trend, you will see green and energy-efficient buildings are here to stay. zz

Green peace By Dr. Chandrashekar Hariharan

A green home entails a little more capital cost at the start, but in the end it helps you recoup the additional cost in 5-10 years

Green peace

 Let’s first make the distinction, for the sake of convenience and clarity, between an ecologically sustainable home and a green home. The former is something that you build with materials that make for the least use of exhaustible natural resources — a typical farmer’s house is the best example, with a combination of clay walls, cowdung surfaces, thatch roofs, limestone-coated walls. There have been homes in the urban context that have attempted to use some ‘traditional’ elements but not always with success on reducing the use of natural resources. So a house built with traditional architecture is not necessarily green.
A green home, on the other hand, is what you ‘architect’ and ‘engineer’ in terms of solutions for a regular urban home, taking into account the use of building materials for floors, walls and roofs and windows; the use of systems that reduce consumption of water and energy without compromising comfort or convenience the way you define them as a dweller. If you were willing to spend a little more as capital cost at the start, you can secure savings into the future that can help you recoup your additional capital cost over five to seven or, may be, 10 years, depending on the feature you are adding to your green home.

Green homes can help you save as much 30-50 per cent in your energy bills. With the right elements in place, you can rely less on fresh water and, therefore, increase water security. Beyond savings, green homes can help you generate some wealth from waste, by managing its conversion into either manure or compost or even energy for your kitchen. The important thing is that a green home in the urban context will enable you to reduce your dependence on government infrastructure for water, energy and waste.

First, green homes don’t cost more — they need a different approach to design and planning; they need your effort to find the right vendors for the right inputs that can offer your solutions that either cut energy and water bills; or increase lifecycle of products you install at home. It is a question of how you spend the money, and not how much more — or less — you spend in building a green home, as opposed to a regular home with conventional materials that we have known for the past 50 to 60 years.

The cost, like in any house, is to do with what you want in a house. Where a green home distinguishes itself is in the way you have employed materials. For example, using soil blocks instead of bricks increases the duration of your building, helps you avoid plastering externally (therefore reducing cost), while also adding to the looks of the building. The use of natural floors increases the aesthetic appeal and even the therapeutic value of your house. Ask anyone with arthritis or rheumatism who walks barefoot at home on vitrified or ceramic tiled floors, and then for some months on natural floors. Their pains dramatically ease with natural floors!

So, a green home is not about price, it is a whole new order of the future. It is building technology that emerges from careful thought on design and human needs. In India, 10 years ago, a few green buildings that were built by pioneers like the government’s Indian Green Building Council (IGBC) and by some private sector initiatives, witnessed a capital cost delta of about 16 to 18 per cent in going green. Today, that figure has come down to a cost differential of near-zero — for two reasons: one is that products have become far cheaper (for example, waterless urinals are now available at Rs 6,000 against Rs 30,000 in 2003) and two, for the greater knowledge of how to achieve resource-efficiency among a growing group of architects and water-energy consultants.

This means that a green building costs the same as a regular building, although there is still a segment of the mainstream building industry (and Indian industry at large) that is not willing to concede this for their lack of understanding of design solutions, and the dearth of professional architects and service consultants who have the expertise of incorporating such energy efficiency into their design approaches.

The sum and short of it is this: clearly there is no cost difference. However, there is need for many thousands of professionals who can guide such approaches for promoters and managements of builder companies and industry at large. This is where the concept of zero energy development (ZED) comes into play.

The idea of ZED is central to going green. People do not connect the dots between the specific benefit that a product or a service offers them and the contribution they are making to save the ‘only house we have, our planet’. A ZED idea in action relates to how a customer sees the benefit of financial savings or ROI for the money she puts in to purchase a product or service. It also at once offers the customer the feel of why she is doing well for herself while she is also doing good for the planet. How her purchase is lighter on her wallet, while being lighter on the planet, too. It is therefore not just the buying, but what she is buying into.

Your average home consumes about eight units a day. If half your need (four units) were to come from localised solutions like solar photovoltaic power, the total demand for domestic energy will drop by half as well.

Examples of such ZED ideas in action are: an air-conditioner that saves about 70 per cent on energy and therefore offers a payback of less than four years for the investment on the air-conditioner. You can buy a regular AC at Rs 22,000 and pay three times the energy cost for every hour of its use; or you can buy a green zero-energy-developed AC that (a) uses no ozone depleting substance for cooling the air, (b) works on a 5-amp mode (avoiding therefore the installation of too many 15-amp switches in your home and so saving on the energy peak load for the house), and (c) consumes less than 400 watts as energy load while keeping your room as cool as any other AC.

The example extends to other simple household appliances like a pump for drawing water from a borewell, a washing machine that saves energy or water, a microwave oven that needs a lower ‘surge load’ and so saves on designed energy peak load of the house, or a geyser that works at 0.5 kw against the regular 3 kw system now on the market …. there are dozens of such examples.

The ZED idea in action usually also demonstrates reliability, economy, efficiency, excellent function and finishes that are the finest. The customer also understands how to connect the dot to the larger picture of how a saving in his house can bring down dramatically at the city’s level (if all of us take to such ZED practices) the demand for energy; how a saving of 70 per cent in energy will reduce our dependence on coal for thermal plants and therefore bring down the abuse and degradation of forests for coal extraction.

Another example of such ZED ideas in action is the purchase of a house that reduces about 3,000 carbon tonnes for every set of 70-80 apartments of 1,500 sq ft. The natural resource-efficient structural systems, the avoidance of bricks and clay blocks (because of top soil abuse), use of chemical-free waterproofing compounds and non-toxic waterproofing treatment systems or paints, avoidance of use of ceramic tiles which are high on embodied energy in their manufacture.

Use of ZED air-conditioning systems that are pollen-free and not ozone-depleting in their functioning, treatment of all waste water in a way that they can be up-cycled and reused for flush tanks or gardens or car wash, and such other use at home (which account for over 50 per cent of water use in any house), use of rainwater harvest systems to ensure that about 60 days in a year come from such capture of rainwater, use of flush tanks that reduce by 70-80 per cent the drain of water with every flush, use of reused steel where possible for construction, use of treated water for construction and reduction of construction water with systems and smart protocols for construction management.

These are just a few examples, there are, in fact, about 58 such ZED practices that make for either reduction in use of manufacture energy or offer post-occupancy efficiency in the use of energy and water. Going green, actually, is not just about eco-friendliness, it’s about economics as well.

Where green is a way of life by Dr. Chandrashekar Hariharan

01HAB-Eco-build_01_1473191eChandrashekar Hariharan of Biodiversity Conservation India Limited (BCIL) & Vice-Chirman – IGBC, Bangalore, spoke to The Hindu-HABITAT to share his views on the existing problems staring at the city and where he has intervened to bring in a difference.

We are sensitive about sharing a river. We gregariously welcome home water-tankers.
We are the lifestyle-conscious Bangaloreans, who understand the water problem of this ever-expanding city like never before.
But are we being tunnel-visioned into meeting our immediate water requirements, while not looking at the dire, dry future?

Here’s a fact. The average water consumption of a Bangalorean per day is 140 litres. The overall supply of water from the Cauvery as well as ground water sources to the city is 1,023 million litres/day (MLD).

The total demand for water in Bangalore is 1,342 MLD. That means 319 MLD less than the requirement or over 22 lakh people without their average quota of water.

The sudden realisation is that you are one among the two million and that’s not a small number to get out of.

The green step

With forethought for the impending ecological disaster, Zero-Energy-Driven (ZED), the market face of BCIL, has been an active crusader in the realm of eco-sustainability. ZED has been redesigning urban living in a way that it addresses problems related to water, energy and waste. All eco-sensitive homes created by BCIL are 100 per cent independent of BWSSB and 70 per cent independent of the power supply board.

Rainwater harvesting, ground-water replenishing and other water conservation methods have made every ZED-home water-positive. The solar-lit residences also enjoy the freedom of power since they not only have stable, pollution-free, home-generated power, but can some day supply back to the grid, in the long run, when the government permits such a regime.

Every ZED home saves 100,000 litres of water a year, and more than 100,000 KWh of power every year. These are not exclusive to ZED homes. Any one of us can future-proof our homes and cut our city some slack by incorporating some of the smart technologies that are easily available with experts.

ZED has been based out of Bangalore since 1994. Every step taken by ZED in its journey of over two decades has been towards restoring the charm and helping the city respond to the challenge of growth. On the eve of World Environment Day it is good enough reason for us to retrospect and redefine Bangalore to make it a livable city.

Rainwater harvesting? What’s that?

getimageEven After Many Deadlines To Make It Mandatory, Residents Of Some Areas Think RWH Is A New Concept Many Prefer To Buy Tanker Water Rather Than Install The System.

Bangalore: Deadlines would have come and gone. Still many Bangaloreans are clueless about rainwater harvesting (RWH), though it is compulsory to have it in most residential plots, with conservation of water being the buzzword.

With supply of Cauvery river water to the city from KRS dam threatening to be reduced to a trickle soon, and no alternatives visible in the long-term, there is a sense of urgency to adopt rainwater harvesting. But residents of Bangalore are sparing little thought to it, and are instead paying through their nose to buy private tanker water and cribbing about it later.

Asked why she has not installed RWH, Mukhteshwari J, homemaker from Rajarajeshwarinagar, said: “I have not heard about it. It seems to be a fairly new concept. How do we do it and is there any rule which compels us to make arrangements?”  When TOI reporter explained the concept, she replied: “We have to get hold of plumbers, undertake works for days to set up a sump and fit additional pipes to collect rainwater from the rooftop. Who has the time to monitor all this?”

Usha Srinath candidly admitted that it is easy to dial an agency to get a watertanker and spend Rs 3,000 a month than build a sump and store rainwater. “I require water tankers every three days. I don’t have the infrastructure to store rainwater like a sump or a tank on my roof or in the garden. All I have to do is dial up the tanker agent and he will get me water anytime of the day,” she told TOI.

Dasarahalli, Peenya, HRBR Layout, KR Puram and W h i t e f i e l d are becoming deserts of sorts with  most people not getting piped water supply and borewells, the only source of water, drying up. Here too there is an apathetic attitude towards installing RWH among the residents who are either very poor or belong to upper middle class.

“I haven’t yet thought of installing RWH in my house because the consumption is very little. I live with my ailing father and a servant but who will help me find the right person and ensure that I am not charged more than the market rate?” said Reshma Kaur, senior citizen from Borewell Road in Whitefield. (Inputs from Kinnari, Sanjana Vasudevan and Deepika Burli)

Pilgrim flow to Kudala Sangama takes a big hit

The other side of the water crisis in Bagalkot district is that tourist inflow has been hit. This is because pilgrims visiting Kudala Sangama seem to be having second thought, thanks to the severe drought and both Krishna and Malaprabha rivers drying up. Pilgrims who come to pray at the Aikya Mantapa or the holy Samadhi of Basavanna, the 12th century revolutionary saint, take a holy dip in the rivers. But in the past 15 days, the number of tourists has decreased from 1,000 to 700. However, the Kudala Sangama Development Authority has made arrangements to supply water through tankers.

Fountains at Brindavan too become a casualty

Planning to visit Brindavan Gardens? Here is a dampener. The beautiful fountains have gone dry because of low water level in the Krishnaraja Sagar (KRS). Officials of Cauvery Niravari Nigam Limited say that about 20 fountains on the south bank have stopped functioning. But those on the north bank, including the famous musical fountain, are still working. They too will cease to function once the water level plummets to below the 50 ft mark, says an official. This is because most fountains work depending on the water pressure in the dam. The next on the hit list could be the boating facility.
