Green Building

Green building is the practice of increasing the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment during the building's lifecycle, through better siting, design, construction, operation, maintenance, and removal.

Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

• Efficiently using energy, water, and other resources
• Protecting occupant health and improving employee productivity
• Reducing waste, pollution and environmental degradation

The Confederation of Indian Industry (CII) plays an active role in promoting sustainability in the Indian construction sector. The CII is the central pillar of the Indian Green Building Council or IGBC. The IGBC has licesensed the LEED Green Building Standard from the U.S. Green Building Council and currently is responsible for certifying LEED-New Construction and LEED-Core and Shell buildings in India. All other projects are certified through the U.S. Green Building Council. There are many energy efficient buildings in India, situated in a variety of climatic zones. One of these is RMZ Millenia Park, Chennai, India's largest LEED gold-rated Core & Shell green building.

CII-IGBC recently announced that Shree Ram Urban Infrastructure - a developer - is attempting the first ever LEED Platinum rating (Core & Shell) in India and will be the first ever residential building in the world to do so. Entitled ' Palais Royale', the building will be located in Worli, Mumbai with an estimated height of over 1,000 ft (300 m).

How about living in a 'green building'? The popularity of such eco-friendly 'green buildings' with their own water harvesting and solar power systems is catching on in India and the high price is no deterrent.

Green buildings also have their own water re-cycling system. More than 50 percent of the building is covered with glass - making it reflect away the sun's rays and helping to keep the inside cool and save on electricity - among other eco-friendly measures.

Starting with a modest 20,000 sq ft green building in 2004 in Hyderabad, green buildings today account for over 235 million sq ft spread across India.

Now there are 315 green buildings in India, including 250 commercial. They include IT parks, hospitals, airports and educational institutions.

Of the 315, as many as 60 green buildings - or nearly 20 percent - have come up in Mumbai alone. The remaining are in other cities of Maharashtra. The important buildings in the city are the Hiranandani BG Building, K. Raheja group, Enercon India Pvt Ltd and Kalpataru building.

The Indian Green Building Council (IGBC), a part of the Confederation of Indian Industry-Sohrabji Godrej Green Business Centre (CII-Godrej GBC), Hyderabad, is credited with spearheading the green building movement in India since 2001.

The CII-Godrej GBC was India's first certified green building spread over 20,000 sq ft in Hyderabad.

"It is growing in popularity in a big way. By 2010, we expect about 1,000 green buildings, with over one billion sq ft to come up all over India," S. Raghupathy, senior director and head of CII-Godrej GBC, told IANS here.

He said an average investment of Rs.500 million has to be made per building to make it 'green', and the total investment in green buildings would be a whopping Rs.500 billion by 2010.

Green buildings cost 3-8 percent more than conventional buildings. However, the higher cost is recovered within two-three years by the handsome savings in maintenance costs, making the concept extremely popular.

Explaining the benefits, Raghupathy said that since such buildings use natural light and air, energy savings could be up to 35 percent, while water savings can be up to 40 percent and productivity benefits up to 15 percent.

Raghupathy said the day is not far when green buildings - offering water conservation, energy optimization, use of recycled products, and renewable energy, all of which ensure environment protection - would be the accepted norm of the construction industry.

The concept, currently implemented in 75 countries, has also spurred a heavy demand for many new construction materials, equipment, systems and services, leading to a transformation of the market.

"There is a huge demand for green building materials and equipment like high performance glass, wall and roof insulation, low VOC paints, adhesives, sealants, CRI (Carpet and Rug Institute)-certified carpets, specialized wood, roofing material, fly ash blocks, eco-friendly chemical waterless urinals, high performance chillers, carbon-dioxide sensors, root zone treatment plants, wind towers, and other things," Raghupathy listed.

"We estimate the market potential for all such green building materials to be about US$40 billion by 2012. This clearly testifies the growing popularity of green buildings and their acceptability among people," he pointed out.

On Sep 27, the CII-Godrej GBC is holding the sixth Green Building Congress in Mumbai, which will include an exhibition and an international seminar on green buildings.

Among other things, the congress will discuss how the IGBC can usher in a 'green building revolution' in India and help make it one of the world leaders in the field by 2010.

Though India has never been a significant player in the global skyscraper stakes, one building promises to change that and for all the right reasons.

Introduction

The India Tower, currently under construction on the Queen's Necklace, the scenic Marine Drive in South Mumbai, is expected to dominate the skyline of India's main financial district. At 300m, it is a giant by Indian skyscraper standards. But when it is ready in 2010, the Burj Dubai is expected to dominate the global building height stakes at about double that height. So what is the main claim to fame for the India Tower?

The USP(s)

It might well be the tallest building in the world in its class of green-rated buildings. Designed by New York-based FXFOWLE architects, it will be a LEED-Gold certified project. Here are some of the features planned to improve its energy-efficiency:

• A solar chimney to generate electricity (Solar chimney's need to be very tall - so incorporating one into the design of a skyscraper is really cool.)
  
• On-site waste water reclamation (ease the load on public facilities, plus build more reliable ones)
  
• Daylighting - a process to ensure maximum usage of sunlight for lighting within the building
  
• Solar shading, natural ventilation and rainwater harvesting

The rotating form apparently comes from functional requirements (whatever those are - but it certainly looks kewl).

Mapping The Trend

This is a building for the very rich - with "a custom-designed residential-style Park Hyatt hotel and serviced apartments, and long-lease and duplex penthouse condominium apartments", in addition to luxury-brand retail and hospitality. (We the poor might benefit if they open up a sky-walk for the public though - imagine the view!)

But most new trends start with targeting the rich. The premium they pay helps fund research into making them more common place and affordable.

If India's tallest building is going to be one of its greenest, then that is a solid commitment we as a society are making towards sustainability.

CHENNAI: When RMZ Millennium Park in Chennai was categorised as a LEED gold building by the Hyderabad-based Indian Green Building Council (IGBC) in September this year, the tally of certified green buildings in the city went up to nine.

Although Chennai’s realty sector embarked on the green quest in 2004, it is only now that the city is emerging as a top contender in energy-efficient and user-friendly office structures, ranking third overall in the country. What’s more, nearly 45 more commercial buildings in the city have registered and are awaiting the green-building certification.

“It is a reflection of the growing concern for environment and energy, and the awareness that huge consumption also leads to huge depletion of resources,” said C N Raghavendran, who heads the Chennai chapter of IGBC. “The concept of green buildings evolved due to the oil crisis in the seventies, and the growing concern over huge consumption of energy, water and other resources in the last 30 years. A green building consumes 40% less energy and 20% less water than a non-green building,” he said.

The movement that took shape in the US, has caught on with India, which now ranks fourth in the world after the US, Australia and Canada in embracing green. The guidelines for a green building, which originally followed American standards, were indegenised after the formation of IGBC in 2002, a CII initiative. The concept of LEED rating arrived in 2005. “The green-building concept is a holistic one, where a lot of research has gone into products which are energy-efficient,” Raghavendran said.

Though structurally a green building doesn’t differ much from other buildings, it causes minimal disturbance to landscape and site condition. It uses recycled and environment-friendly building materials as well as non-toxic and recyclable waste material, manages water and power efficiently, and has better indoor air quality leading to better health and safety of inhabitants.

“Site sustainability is a key factor and buildings which come up near a railway station or MRTS station, making public transport accessible to users, will score more,” said Raghavendran.

So what are the criteria for declaring a building green? Use of fly-ash bricks (a residue from coal-powered thermal plants), high-performance glass, gypsum waste boards instead of wood, broken ceramic tiles on roofs (to absorb and dissipate heat), application of heat-reducing roof insulation, use of glass skylights to permit natural lighting, taps that manage water consumption, and reusable waste-water system, and energy efficient AC with carbon dioxide sensors can help a building get green tag.

“The intention is to replace the shoe-box environment with a healthier one,” said Deepa Sathiaram, consultant for specialised sustainability solutions for green buildings. “Saving energy is a key concern. Today even 25 degrees is uncomfortable unlike 15 years ago when no one needed an AC even when the temperature touched 30 degrees. Smart AC systems which take into account the total heat coming in, and the internal heat generated by computers, machines and people are increasingly used,” she said.

“The certification is only incidental. What is important is to transform the green idea into workable solutions and sustain it,” said Vinita Badawe, one of the first architects to incorporate green concepts in designs, as early as 2002, long before green buildings became a byword.

The green envelope is an expensive outing: the construction cost can go up by anything between 5% to 12 %. Moreover, there is no government incentive for builders who take the green road.

“The end-user benefits are tangible, and we are confident of recovering the incremental cost in three to five years time,” said Chitty Babu, managing director of Akshaya Homes.

CHENNAI: The new Rs 425-crore Assembly complex, coming up on the Omandurar Government Estate at Chepauk in the city, will be Tamil Nadu's pride for more than one reason. It is not only designed to be an architectural marvel of modern times but is also poised to set a new benchmark in the design of eco-friendly buildings in the state.

The state government is aiming at getting Platinum certification, the highest rating for green buildings in India, for the sprawling complex. "We are taking efforts to comply with the prerequisites for getting the prestigious rating," official sources said.

If the requirements are met, the state Assembly complex will be the first in the state and one of the few in the country to become ‘Platinum- LEED' (Leadership in Energy and Environmental Design) rated green building.

Besides, the Public Works department has taken efforts to plant about 1,000 saplings on the complex in the next couple of months. "We've held discussions with Forest department officials in this regard. We will also take efforts to relocate the existing trees wherever it is possible. Money is not a constraint and will take every possible effort to save the trees. Already, two or three consultants are working on the modalities,' the sources added.

While the CII-Godrej Green Business Centre, Hyderabad, Wipro Technologies, Gurgaon and Hiranandan BG Building, Mumbai, are some of the proud winners of the Platinum in India, the buildings of Grundfos Pumps India Ltd, Olympia Technology Park and L&T, EDRC are among the few in the city to have won the LEED-Gold.

GURGAON: Haryana governor A R Kidwai inaugurated a green building in the Millennium City on Tuesday. An initiative of S M Sehgal Foundation, a non-profit organisation working for rural development in Mewat and Kurukshetra, the building is located in Sector 44.

A solar power generation unit, a water-harvesting mechanism to reuse rainwater and use it for groundwater recharge and built in accordance with zero-waste concept are factors which contribute to the construction's "greenness".

Speaking on the occasion, Kidwai said, "Solar energy is the future and we are wasting it. To meet the growing demand for electricity, hydro power combined with solar energy will be ideal for India.''

He added that the government of India had introduced a scheme to set up 50 MW solar generators in different parts of the country.

Suri Sehgal, chairman, S M Foundation, said green buildings increase the efficiency with which buildings and their sites use and harvest energy, water and materials and reduce the building's impact on human health and environment through better design, construction, operation and maintenance.

The building has been constructed according to the platinum rating of Leadership in Energy and Environmental Design (LEED) standards set by the US Green Building Council.

Expert said this was the first institutional building in Gurgaon that had been designed to minimise carbon dioxide emissions. Also, wood had been used in place of aluminum for doors and windows and the use of burnt brick was minimized, while no imported stones were used in its construction.

"An interesting feature of the building is that it derives beauty from waste. The entrance lobby, boardroom and the central atrium use waste plywood wooden planks, broken tiles and glass to demonstrate how waste can be converted into a beautiful resource,'' said Sehgal.

"The 35 KW solar photovoltaic installations on the roof meets 100% of the building's basic electricity needs, including computers, lighting, fans, and mechanical ventilation directly from solar energy,'' he further said.

He added that though the cost of construction was 15% more than a traditional building, the extra cost incurred could be recovered by way of less electricity consumption in five to eight year's time.

India’s First Green Housing Project Completed

Rabi Rashmi, Kolkata

Built in Kolkata, Rabi Rashmi Abasan is India’s first completely solar-powered housing complex. The complex has been built on a plot of 1.76 acres at Action Area I in New Town. The 58 kilowatt project consists of 26 photovoltaic systems comprising 464 units of Conergy C125W solar modules. The solar modules were customized to fit on the building roofs. Each home will generate 2kW of power. The solar power generated will be used to fulfill electricity needs of the homes, and the surplus power will be sent to the public grid. This is also India’s first building-integrated photovoltaic (BIPV) project. The building-integrated photovoltaic (BIPV) system would save 0.5 kgs of carbon emissions for every kw hour of solar power produced.

The houses will have both passive solar architecture and active solar energy features. The passive solar features will make houses cool during summer, ensure natural light, and better air circulation inside the house. The active solar energy elements include the solar water heating system. The housing complex will also have other sustainable features like garbage management system, battery operated pick-up vans for residents, solar street lights, and a swimming pool with solar water heating system.

The complex has been conceived, designed, engineered and built by West Bengal Renewable Energy Development Agency (WBREDA) and Bengal DCL. The solar photovoltaic has been installed by SunTechnics India, a brand of the Conergy Group.

Kolkata to get nine green buildings

As many as nine "Green Buildings" are coming up in Kolkata in the next two years. The concept, which is relatively new in India, is steadily taking off with environment conservation becoming a part of the corporate social responsibility.

Speaking on the sidelines of a seminar organied by Confederation of Real Estate Developer's Associations of India in Kolkata, S C Kumar, senior advisor, Leadership in Energy and Environmental Design said, as many as 160 real estate projects across India, with nine in Kolkata, have got LEED recognition.

The first green building project was started in Hyderabad in 2003, and major changes have taken in the field since then, he said.

"India will usher a green revolution in real estate, and become a world leader in the field by 2010," he said.

The investment in a green building is 5-10 per cent more than an ordinary building, but the benefits sustain for a long term, he said.

The Leadership in Energy and Environmental Design green building rating system has been developed by the US Green Building Council. It provides standards for environmentally sustainable construction.

Since its inception in 1998, LEED has grown to encompass over 14,000 projects in 50 US states and 30 countries covering 1.062 billion square feet of development area.

Kolkata scores a first: to have Green Rating for its buildings

Kolkata, August 06 Keeping in view the climatic conditions of West Bengal and the rising need of renewable energy, Green Rating for Integrated Habitat Assessment (GRIHA) under the Ministry of New and Renewable Energy was launched in Kolkata on Wednesday.

Speaking on the occasion, Dr R K Pachauri, director general of The Energy Resources Institute (TERI), said, “The West Bengal government has already been very enlightened on the issue and that is one reason why GRIHA has been launched first in Kolkata.”

According to him, GRIHA will be movement and West Bengal can set precedence for all the other states. He added that he has requested Prime Minister Dr Manmohan Singh to reduce the subsidy on kerosene and instead subsidise solar lanterns to encourage the use of renewable energy in the rural pockets.

He added that western rating systems are not suited for the Indian climate and GRIHA has been designed exclusively for Indian buildings.

GRIHA is a national rating system, by which, green buildings will be rated by the West Bengal Green Energy Development Corporation Limited (WBGEDCL) with technical expertise from TERI. The aim of a green building design is to minimize the demand of non-renewable sources and maximize its utilisation.

The centre for environmental science and engineering at IIT Kharagpur is the first building that has undergone green certification and has been awarded a five star rating. Buildings will be rated on the basis of design, system design, including ventilation, water and waste management, in door environmental quality and selection of ecologically sustainable materials.

“West Bengal already has Rabi Rashmi Abasan, India’s first solar housing complex, in New Town, Kolkata, we plan to have more such projects in future along with project on solid waste management with assistance from JBIC (Japan bank for International Cooperation) and JNNURM (Jawaharlal Nehru National Urban Renewal Mission),” said Ashok Bhattacharya, minister for municipal affairs and urban development.

SP Gon Chaudhudhuri, MD of WBGEDCL said that the corporation will appeal to the urban development ministry to make GRIHA rating mandatory for all commercial buildings consuming above 100 KW of electricity.
