Energy-inefficient design

This is the Airtel office on Bannerghatta Road, near the Jayadeva flyover. True to the “modern” trend in architecture, the facade of the building is all glass; but look at the effect on the inside.

Since one entire wall is glass, the afternoon/evening sun pours in through it.

This is all very well for cities in cold countries where sunshine is a rare commodity, and buildings need to be heated. But here, where the mercury yesterday was at 34 degrees Celsius, it meant a huge volume of space where things were very uncomfortable.

Here are the staff, who have to sit facing the hot and intense sunlight throughout the afternoon:

The customers also have to sit in the sun, but at least they have their backs to it..and they are there for far less time.

The Airtel office is air-conditioned; I can also guess at the amount of energy and electricity it must be taking to cool down the space heated by the glass design of the building.

The architect who designed Jal Bhavan (it’s the building in the dead centre of that map, next to that “pleated” building) has said that glass is a bad material for architecture in India; it heats up the inside of the buildings, which then have to be cooled down at enormous cost in terms of electricity/energy.

Having been in the Airtel office, I would tend to agree.

    Well Said Deponti, we wear blazers in hot country, we use glass when global warming is in rise – we blindfoldedly follow the westeners who do it for their needs & some time for the heck of doing it and later telling the whole world to abide by rules !!

    Glass is an amazing material.i love it.
    The architect has used it in a disastrous way, not even taking note of the summer sun in Bangalore. Bad design.good material.

    Glass can be recycled 100%. It can be engineered with tiny photo voltaic cells to generate solar energy.It can be tinted to reduce uv rays… ( i could go on for ages).

    We follow ‘westerners’ because they put in lots of money and time into research of material technology, which we conveniently take from them.

    Solution: in this case tinting the windows would be an efficient.

    vishnukumar, you da man. i agree with you, especially the 3rd paragraph.
