We all have heard about Green buildings, so, let’s discuss here on ArchiVerse this with some examples present in India. So, let’s try to see what sustainable practices are present in these buildings. So what is a green building? It is a building which uses less water, optimizes energy efficiency, conserves natural resources, generates less waste, and provides healthier space for occupants as compared to a conventional building. There is a constant need for sustainable practices to stop the damage happening to the environment. So, to bring in the limelight here we are listing the top 10 green buildings in India.
Rajiv Gandhi International Airport in Hyderabad – Most Advanced Green Airport
India’s Sixth busiest airport, Rajiv Gandhi International Airport (RGIA) sets a benchmark for the green buildings in India since, it consumes less water, electricity and conserves natural resources. GHIAL operates RGIA and has won the Centre for Asia Pacific Aviation (CAPA) Chairman’s Order of Merit for its focus on environmental sustainability. Thus, becoming the First Airport in the Asia Pacific in its category to become carbon neutral.
Also, the commissioning of the 5 MW solar power plants and various energy conservation measures. This includes planning and execution for LED lights for the entire airport. Also, Building Automation System, optimization of air conditioning units and vast green cover (273 Hectares) around the airport to reduce the carbon footprint. It has won numerous environment-related awards like Golden Peacock Environment Management Award and 2015 and Confederation of Indian Industries (CII) Award for “Excellent Energy Efficient Unit” in Energy Management 2014 and 2015.
Bank of India – Best Green Building in Goa
A space of eco-friendly lights and air Conditioning, intelligent glazing, modern Capsule lifts and indoor fountains. All these make the bank one of the best green buildings in Goa. The building uses nano misty blue softening colour glass manufactured by Saint Gobain Glass, India for producing the cool Effect and saving energy. Certainly, the role played by Glass in this structure makes it a great example of Sustainable Architecture. Also, the structure required a system that would provide it optimal energy and cooling solution at a minimal cost. Since glass has the ability to lend itself for heat regulation. Thus, helps in regulating internal temperatures efficiently and reducing the dependence on power, in a more sustainable manner.

CII Sohrabji Godrej Green Business Centre, Hyderabad
It is the world’s best example of passive architectural design. It was the first building outside of us which has been awarded LEED platinum rating at the time of its inauguration. And, the unique feature of this building is, it does not let out any waste and recycles it all within. Here are the points which make this one of the best green buildings in India:
- Courtyards– The courtyards act as “light wells,” illuminating adjacent work areas. When this light is not sufficient, sensors trigger the deployment of efficient electric lights. And, the Dimmers automatically control the illumination levels, turning the lights off when they’re unnecessary. Also, occupancy sensors prevent light from being switch on at an unoccupied workstation.
- Internal Lighting– The courtyard may be hot because of the temperature as a result the cool air replaces it. Also, the hot air being lighter than cold air rises up making the place cooler and above the terrace gardens keep the temperature down forcing the hot air to rise up further.
- Roof Garden- Absorption of heat and radiating it into the building. Minimization through the roof gardens covering 55% of the roof area. And Seepage into the ground has been installed in pedestrian areas and parking.
- Natural Lighting– Natural light deflection systems can direct light deep into the room and ensure better natural lighting provisions.
- Reflective glass (mirror)– This material reduces the penetration of radiation from the reflecting side to the non-reflecting side (penetration of 11-37% of total striking radiation). Such glazing is used in this building where it is desirable to maintain eye contact with the outside as well as to prevent penetration of radiation and in areas where it is hot most days of the year.
Suzlon One Earth, Pune
It is India’s largest and one of the world’s biggest producers of “clean” wind energy. This is one of the unique offices, Designed by Christopher Charles, spread over ten acres locating in Pune. This structure is one of the largest green building projects of the country and is also one of India’s first buildings to be LEED certified. The campus has 18 hybrid wind turbines that fulfil 7% of the total energy consumption.
And the rest of the energy demand is met from off-site wind turbines. The structure is designed in a way to ensure maximum daylight exposure thereby reducing artificial lighting consumption. 100% rainwater is harvested, 100% of greywater is recycled via an on-site sewage treatment plant into flushing, air-cooling and landscaping systems attesting to One Earth’s water-efficiency. Also, Water fixtures including low flow fixtures that reduce in-building water consumption by 65% and touchless urinals with hydronic sensors all help reduce water consumption and make One Earth water efficient.
