Ancient Vigyan – Natural Cooling Effect
The architects of ancient India designed monuments with natural cooling systems. Rajasthan’s Hawa
Mahal is a perfect example of how the interiors served as natural coolers without the use of electricity….
Hawa Mahal also known as Palace of Winds is one of finest tourist attractions of Jaipur city. This beautiful pink sandstone palace was built by Maharaja Sawai Pratap Singh around 300 years ago. Its unique five-storey exterior resembles the honeycomb of a beehive. It has 953 small windows called jharokhas decorated with intricate latticework. The purpose of the lattice design was to allow royal ladies observe everyday life, festivals celebrated in the street below.
The latticework lets in cool breeze into the area due to the Venturi effect in Physics, creating almost an air-conditioning like effect during peak summers. The jharokhas serve as a device that generates wind for those who stand inside. The air blown through is compressed and is reflected through the windows – very similar to the ordinary laws which govern a modern-day air-conditioner.

The “Venturi effect” is a physical principle according to which a fluid that moves inside a pipe or channel increases or decreases its pressure according to its speed.
