Smart window material

Description

GS PAPER III: Science and Technology- developments and their applications and effects in everyday life.

Context: Researchers at the Indian Institute of Technology (IIT), Guwahati have developed a smart window material for automatic climate control of buildings that would ultimately help in developing efficient automatic climate control.

It can provide an alternative solution for maintaining ambient indoor temperature and lighting inside a building or a vehicle.
It is designed using noble metals as well as their relatively inexpensive alternatives that can dynamically control the intensity of transmitted solar radiation.
The emergent smart windows, on the other hand, can dynamically adjust the amount of light and heat radiation entering a building in response to external stimuli, thus conserving the building’s energy.
Design of smart windows are tunable for all-weather conditions.

What is geo-engineering?

Climate engineering or climate intervention, commonly referred to as geoengineering, is the deliberate and large-scale intervention in the Earth's climate system.
The most prominent subcategories of climate engineering are solar radiation management and carbon dioxide removal.
