Tamil Nadu leads in LEED buildings


Severe power shortage and lack of infrastructure developments notwithstanding, Tamil Nadu can be boast itself as having the highest number of energy-efficient buildings, popularly known as “green buildings” in India. According to Indian Green Building Council (IGBC), the southern state has 47 green buildings and 57 more were registered for certification in 2011. The number of LEED certified buildings in India is currently stands at 212.

Among the state capitals too, Chennai, the capital city of Tamil Nadu, tops the chart with 42 eco-friendly buildings which have Leadership in Energy and Environmental Design (LEED) certification.
Chennai is followed by Mumbai with 29 green buildings and the National Capital Region (28), among cities awarded LEED certification by IGBC. Hyderabad and Bangalore are tied in fourth place with 24 each and Kolkata is sixth with eight, a report in Times of India said.

According to IGBC, there has been a sharp increase in the number of buildings in Chennai that have been awarded green certification over the past three years.  Only 10 buildings in the city won the rating from 2004 to 2008, while 37 buildings received the rating between 2009 and 2011. Experts attribute this to rising ecological awareness as well as business opportunity: Green certification gives builders a new branding option.

Nearer to Chennai, Sriperumbadur, the upcoming satellite town, has three green buildings , textile town Tirupur has two, and Madurai , Salem, Siruseri and Coimbatore have one each.

Among the green buildings in Chennai -- the Turbo Energy office complex in RA Puram, Menon Eternity in Alwarpet and Shell Business Service Centre, all with platinum certification, the highest rating. Platinum is followed by gold, silver and certified ratings, based on sustainability, waste management, use of natural resources and indoor environmental quality.

Anna Centenary Library and the new Tamil Nadu assembly building, both of them were in news recently, are gold-rated as is Express Avenue Mall, World bank building and Olympia technology park.  

Viswa Syamalam, a house in Madipakkam, is one of the two individual homes in the country to have received a green rating. It was awarded platinum rating in 2009. The other green home is in Hyderabad.

Tamil Nadu developers grab business opportunity as eco buildings get popular, which not only saves energy and water bills, etc., it also protect and saves environment.

What is a green building?

A green building is one that uses less water, is high on energy efficiency and sustainability, generates lesser waste, conserves more natural resources and has a better indoor environmental quality than a conventional building.

Today's monoliths of concrete, glass and steel will soon be replaced by green, self-sufficient buildings and towns. Eco-friendly blueprints are off the drawing board, hauled onward by energy-saving rafters and photovoltaic louvres on gigantic cranes, as the cities of the future rise from the grime of urban sprawl. 

There is also a rise in the number of buildings that have been registered for green certification , with builders needing to ensure that the structure meets certain parameters in terms of sustainability, waste generation and conservation of natural resources.

Fifty-seven buildings were registered with IGBC for green certification in 2011, 13 buildings in 2010, and 25 in 2009. The rating is divided into four categories , based on how ecofriendly the structures are, with platinum at the top, followed by gold, silver and certified buildings

"Although it costs more to construct a green building, the returns are high," says a spokesperson for the IGBC, adding,  "The government should provide initiatives to encourage green developers. Green builders are provided incentives in Pune and Greater Noida . A lot of people also opt for green certification as it makes it much easier to get environmental clearance."

More for green

Constructing a green building costs 3% to 5% more than a normal building, but subsequent expenditure is low. On an average, these buildings consume 40% to 50% less energy than a normal building and cut water consumption by as much as 40%.

Green Building Ratings In India

In India, the IGBC (Indian Green Building Council) gives the LEED (Leadership in Energy and Environmental Design) rating, a system which rates buildings on design, construction and operation and offers four certifications for new constructions: Certified, Silver, Gold and Platinum.

Adarsh  (Association for Development and Research of Sustainable Habitats) founded by Teri (The Energy and Resources Institute), New Delhi, and the ministry for new and renewable energy, (government of India) also issue Griha (Green Rating for Integrated Habitat Assessment) to deal with small residential complexes and homes. Griha ratings range from one star to five star.

  1. Thanks SEAN.. for showing interest in my posting. But unfortunately Chennai has two divergent sides. We need to improve the mindset of the government agencies to understand the modern needs of the residents. Still the development is pretty irregular. South Chennai shows phenomenal growth but north and east part of the city is grossly ignored and not even has basic civic amenities. Keep dropping in...
