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 was the first building to receive the platinum certification outside US and also first in India. This building is designed in such a way to collects the rain water, relies on the natural lighting’s and make use of the solar power.These results in the conservation of energy by 55 percent, compared to the other conventional buildings.

ITC Green Center

 

ITC Green Center located at the city of Gurgaon, Haryana was opened in 2005. This building received the LEED platinum certification. This building recycles and reuses all the water that lands on it, results in zero water discharge. This building uses insulated glasses that keeps the heat out and allows the natural light to transmit into the building. 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

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.

ABN Amro Bank N.V

 

ABN Amro Bank N.V. in Ahmadabad earned LEED platinum certification on 5th December 2007. This is the first bank in India to achieve the LEED platinum for commercial interiors and also the first platinum interiors certification outside US.

Glass existed since the 3000 BC in Egypt and Eastern Mesopotamia. It was discovered coincidentally when calciferous sand finding its way into an overheated kiln and combining with soda to form a coloured glaze on the ceramics. The earliest man made glass item was the non-transparent glass beads; later glass vases and other item were made.

During the 16th century BC the Hallow glass making came into existence in Egypt and Mesopotamia, china and in other civilizations via merchant and sailors who traveled frequently.

In 1500 BC, Egyptian Paraoh Thoutmosis III brought glass makers as prisoners from various parts of Asia, with successful military campaign. It is believed that those glass makers has produced glass pots by dipping a core mould of compacted sand into molten glass and then turning the mould so that molten glass adhered to it. It then be decorated by rolled on slab of stone then let it cool.

Glass Blowing

In earlier 20 BC to 14 AD, The usage of glass spread across the Syrian, Italy where the ancient roman began the process of blowing glass inside moulds by using a long thin tube, by they produced variety of hallow glass items.

The Romans have contributed much to glass by their conquest and trade relationships. It was during the rule of Emperor Augustus, glass usage flourished across France, German and other European countries. It is also believed that the Romans was the first to use glass for architectural purposes, after the discovery of clear glass in Alexandria around 100 AD.

During the middle ages the glass making gradually improved. In Venice, had more expert craftsmen, who traveled to other countries to earn money. They even faced death threats if they live the country, which then was leader in glass industry.

France – Experts

It was in 1688, in France Experts developed new process of making Flat glass, mainly used in Mirrors. The process was pouring molten glass onto a special table and roll it flat, later when cooled it was polished using felt disks, then it is coated with reflective material to produce the Mirrors. French government also took many steps to promote its glass industry by placing heavy duties for glass imports and it also offered Venetian glassmakers high incentives, French nationality with tax exemption. Since then Glass makers like Saint-Gobain have been contributing for the glass constantly.

Modern Technology

Today, Innovation of new technologies in industrial revolution made glassmaker to research on new strategy in glass making which lead to produce them various special purpose glasses such as solar control glass, which can control harmful UV-ray entering the building and at the same time allowing natural lights to flow. The other special glass that came into existence where Fire protection, privacy glasses, Self cleaning glass, Thermal insulation glass etc.

Saint Gobain Glass India, the glass manufacturer has been recognized along with eight other companies for its initiative in Corporate Social Responsibility by the Tamil Nadu Government.
