Cochin airport created news when it became India’s first airport to run on solar power in August 2015. The airport has photovoltaic (PV) panels laid across 45 acres near the cargo complex. The airport can avail 50,000 to 60,000 units of electricity per day through these panels which is sufficient for all its functions. This has technically made the airport “absolutely power neutral.” The implementation of this 12MWp solar power project cost Rs. 62 crore and took six months to complete. It has been set up by Bosch Ltd., Bangalore, and has a capacity to produce 18 million units of power annually. Read more about it here.

The recently constructed Chandigarh international airport at Mohali is the first airport in the country that is ‘totally green’. Spread over 53,000 sq. m, the airport has used environment-friendly green technologies that makes it one-of-its-kind, not only in India, but also in the world. The airport is constructed in a way that no artificial lights would be required to illuminate it during the daytime. It also has a transparent façade with low heat-gain glass which reduces the need for a large amount of air conditioning. The rooftop of the terminal has a 200KW solar plant which is enough to meet the major power needs of the building. Forty percent of the airport is illuminated with LEDs and the air-conditioning is fired by chiller efficient machines. Here’s more about the airport.

2. Magnificent Metro Projects

Starting with the first metro being built in Kolkata in 1984, metros have become lifelines in some of the major cities in India. The Delhi metro started its operations in 2002 and is one of the most disabled-friendly public places in the country, with all stations equipped with ramps, low level control panels in the lifts, and buttons in Braille. With 208 trains serving 140 metro stations, it is the first metro rail and rail-based system in the world to get “carbon credits for reducing greenhouse gas emissions.”

Named one of the top 100 strategic global infrastructure projects at the Global Infrastructure Leadership Forum held in New York, the Hyderabad Metro Rail project will be the the world’s largest project under public-private partnership. It is also the world’s largest elevated metro and is expected to provide transportation to over 1.7 million commuters by 2017.
