IIT-G’s smart window can control building temperature

Guwahati, May 25 (UNI): Making a step towards a climate control system in buildings, researchers at IIT Guwahati have developed smart window materials for automatic climate control of the buildings.

The results of their study have recently been published in the journal, Solar Energy Materials and Solar Cells.


The researchers have designed a smart window material that can effectively control the amount of heat and light passing through it in response to an applied voltage.

Such smart window materials would help in developing efficient automatic climate control systems in buildings.

Dr Debabrata Sikdar, Assistant Professor, Department of Electronics and Electrical Engineering, and research scholar Ashish Kumar Chowdhary have designed smart window ‘glasses’ using noble metals as well as their relatively inexpensive alternatives which can dynamically control the intensity of transmitted solar radiation, depending upon the weather/climate condition, a press statement from IIT Guwahati stated.

The primary consumption of energy in buildings is by the climate control system, in which energy-consuming devices are used to maintain comfortable indoor temperature and brightness. The developed materials will help in designing smart climate control systems in buildings to save energy and reduce carbon emissions.

“There has been increased attention to sustainable architectural designs for better light and heat management in buildings in recent years, and deploying smart windows is the first step for such structures,” said Sikdar.
