Why Should You Live In A Skyscrapers of Several Hundred Metre High?

Craze of touching the sky is the instinct of human from the early age of history. With the invent of aero plane man has developed the new and safe structural and architectural techniques to keep standing a large building of more than hundred stories on the ground. Now-a-days World economies have been typically marked by iconic structures. Be it the Empire State Building which symbolized America's might in the early 1930s, to more recently the Petronas, Twin Towers and Shanghai World Financial Center representing the rise of Asia. To construct this tall skyscrapers vast amount of steel, concrete and glass are required which represent a great deal of embodied energy. Tall skyscrapers are very heavy, which means that they must be built on a sturdier foundation than would be required for shorter, lighter buildings. Building materials must also be lifted to the top of a skyscraper during construction, requiring more energy than would be necessary at lower heights. Furthermore, a skyscraper consumes a lot of electricity because potable and non-potable water must be pumped to the highest occupied floors, skyscrapers are usually designed to be mechanically ventilated, elevators are generally used instead of stairs, and natural lighting cannot be utilized in rooms far from the windows and the windowless spaces such as elevators, bathrooms and stairwells. With many of above disadvantages skyscraper provides some facilities: 
India Tower: A 125-storey tower in Marine Lines,
Mumbai, expected to be finished in 2016

1. Lower temperature: It is like living on a hill station ‐ The drop in temperature (DALR) is approximately constant at 9.78 °C/km (5.37 °F/1000 ft, or about 3°C/1000 ft) viz. The temperature at the top of World One will be almost 4.5°C lower than the ground temperature in the area. 


2. Lesser noise from outside: There is reduction in noise in buildings as we move up and the building and the variation noise is also less as compared to the lower floors. A difference of 30 floors reduces the maximum experienced noise by 30%. 

3. Cleaner air: A steady concentration decrease with increasing height of the concentration of automotive‐related pollutants, such as of PM10 airborne particulate, and of CO occurs in the immediate neighboring of the tower building. 

I. A decrease in concentration of particulates by 10 milligrams increases life by 0.61 years for a 7 year old child. 

ii. With the availability of cleaner air in upper floors, reduction of 20% in lung capacity can be avoided 

4. Better views and visibility: In clear atmospheric conditions, you can see to a distance of 50 kilometers from the top of the building of height 650 ft.

  1. This is serious aristocratic thinking.
