In this 21st century, the world around us is dramatically occupied by multi-storey buildings. The number of buildings constructed per year is getting increased. As a result of this natural resources are getting exploited and polluted to a greater extent. If this status continues, then the future sustainability will be a greatest interrogation. This can be overcome by the construction of the green buildings. The green buildings are totally different from the conventional buildings. The green buildings are the buildings constructed with the energy efficient materials.
The awareness about the green buildings and the necessity of the green buildings has their wide spread all over the world. Many nations started their own organization to award the buildings, constructed as per their rating system. India also includes itself in that list. India adopts a rating system called GRIHA as the National Green Building Rating System of the country. The highlight of the GRIHA is that it also rates the non-air conditioned buildings as green buildings. The CESE building of the IIT Kanpur is the first GRIHA rated building in India.
The Indian Green building council (IGBC) awards the buildings with certified, silver, gold and platinum as per the point that they are getting. IGBC also certify the buildings with the LEED certification under the license of the USGBC. Let us see some green buildings in India with LEED certification.

This building saves the energy and water by 51 percent and 40 percent respectively. This building has saved Rs.1 crore in power cost annually. The construction of this building uses certified woods. This building uses CO2 Monitoring system to improve the quality of the air to provide the fresh air.
The Olympia Tech Park
The Olympia Tech Park covers 1.8-million square feet in Chennai, Tamil Nadu. This is considered as the largest green building in the world. This building was awarded with LEED Gold certification. The energy efficient glass features of this park are low power consumption and 100 percent water recycling facility. This building allows the natural light into the building. The park has a reverse osmosis plant to process the drinking water whilst the recycled sewage water is used to service the urinals and flushing requirements within that building.
Technopolis, a 14-storey building in Kolkata is the India’s first IT infrastructure that earned the LEED Gold certification. It covers 4, 25, 000-sq ft area. This building was expected to reduce the carbon emission by 7,500 tones.
