Smart window material

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.
