As the country faces acute power shortage and the global warming debate hots up, energy conservationists caution against growing number of buildings with glass facades dotting the landscapes of cities as being responsible for energy consumption much in excess that a normal structure would do.

If you see the structures that have come up recently, they are all mostly made with glass. Right from top to below, you can see huge shinning glass.

Though these buildings look very contemporary and stylish, they are the biggest culprit when it comes to energy consumption, says Harsh Narang, director, Modern India Architects.

Glass building are a very European concept because they don’t get much of sunlight. Hence, their main aim is to get maximum sunlight. But, in our country where temperatures at times go as high as 50 degrees Celcius, these glasses take in more of sunlight.

Hence, the offices use more air-conditioners directly resulting in higher consumption of electricity and also in the form of carbon-dioxide emission and also CFCs that air-conditioners generate causing damage to the ozone layer, he adds.

According to a study conducted by Chartered Institution of Building Services Engineers, London, a complete glass building consumes four times more electricity than a normal building.
