With the concept of green buildings gaining prominence in India, developers are now focusing on developing structures that are eco-friendly and use energy-efficient techniques.
Depleting natural resources, rapid industrialisation and urbanisation have led to a negative impact on the environment. Eco-friendly buildings that are energy efficient and use water management techniques are the need of the hour. Some developers have succeeded in creating such buildings.
Which are India’s top 10 green buildings?
ITC Green Centre, Gurgaon
Spread across a sprawling 1,80,000 sq ft, the ITC Green Centre has set a benchmark for green buildings in India. Located in Sector-32, Gurgaon, the building has been awarded the Platinum Green Building rating by USGBC-LEED (Green Building Council-Leadership in Energy and Environmental Design), making it the first corporate house in India to bag this award.
The building is designed keeping in mind the highest environmental standards. It is made up of bricks and concrete comprising of fly-ash and is equipped with high-efficiency equipment that reduces 53 percent energy consumption over a conventional building and 40 percent potable water requirements. Zero water discharge, solar thermal technology, stormwater management system, reflective high-albedo roof paint, minimal exterior lighting and separate smoking rooms with exhaust system are some of the other features of the building.
Suzlon One Earth, Pune
With a capacity to accommodate 2300 people, ‘One Earth’ is another building that has received Platinum certification of LEED. The building is built using low energy materials thus, reducing carbon footprint. 90 percent of the occupied space of the building has access to natural daylight. While the exterior of the building uses renewable energy-based LED street lighting reducing approximately 25 percent of the total power. The ventilation system consists of jet fans that save 50 percent energy by periodically pushing out stale air and bringing in the fresh air.
Patni (i-GATE) Knowledge Center, Noida
Awarded with the prestigious LEED Platinum rating, Patni Knowledge Centre is next on the list of green buildings in India. Located in suburban Noida and built over 4,60,000 sq ft, the building’s depth is designed in such a way that it captures daylight for 75 percent of the occupied interiors. About 50 percent of the area is reserved for open green space. In addition to this, the campus follows the efficient water management practices like rainwater harvesting, solar water heating and drip irrigation. 100 percent sewage is treated and the recycled water is used for the purpose of cooling the tower makeup, gardening and flushing.
Olympia Tech Park, Chennai
Located in the heart of Chennai (Guindy), the Olympia Tech Park has become one of the biggest and most sought after IT parks in Chennai. The tech park houses MNCs that operates day and night which is why energy-saving features and the eco-friendly environment becomes a necessity. Rated as one of the largest gold LEED rating buildings in the world, the building makes use of energy and water saving techniques (rainwater harvesting) and recycling and to attain zero per cent discharge. The dual plumbing line of the building which helps in treating greywater is used for flushing or in irrigation.
Infinity Benchmark, Kolkata
Next on the list is Infinity Benchmark, another LEED Platinum level certified green building which covers an area of 5,60,000 square feet and is spread over 20 stories. The air quality inside the building is maintained by CO2 monitoring sensors and intelligent humidification controls. External walls of the building are made of brick wall block while the roof has under deck thick polyurethane foam for better insulation. An environment-friendly technique like the use of electric cars within the complex is used along with energy-efficient equipment and waste water recycling system.
CRISIL House, Mumbai
With 14 gardens inside the complex, CRISIL House is rated as one of the greenest commercial complexes in India. The interiors of the building are made up of recycled construction material while the atrium at the center of the building allows natural light to seep in covering 70 percent of the work area. At night, energy efficient artificial lighting is used thus, reducing the carbon footprint. The natural lighting technique has helped reduce power consumption by 40 percent.
