This Smart windows cuts off your electricity bills and are environmental friendly

Researchers

at RMIT have developed smart windows that not only saves your electrical bills but are also environmentally friendly. The self-adjusting coating which is thousand times thinner than an electrical hair automatically lets in more heat and blocks sunrays when it’s too hot. This research is led by lead investigator Associate Professor Madhu Bhaskaran and Co-researcher and PhD student Mohammad Taha of RMIT University’s state-of-the-art Micro Nano Research Facility with colleagues at the University of Adelaide. This breakthrough research will help meet future energy needs and also create temperature responsive buildings.

Due to Global warming, temperatures are soaring to new highs every year, prompting the use of more air conditioners in residences as well as in office rooms. This AC’s release chlorofluorocarbons into the environment thereby harming the ozone layer that shields the earth from the harmful UV-B rays from the sun. But the new research drastically reduces the air-conditioning time that not only saves your electrical bills but also indirectly minimises the release of harmful chlorofluorocarbons into the atmosphere. One more interesting aspect is that users can operate smart windows as per their need using a dimmer switch.  Hence the user can regulate transparency on the window and thereby regulate the intensity of lighting inside the room.

The technology behind Smart windows:

The coating comprises vanadium dioxide, and it can be directly applied to the windows without the need of any additional platforms. At higher temperatures say above 67 ºC, vanadium dioxide acts as a metal blocking the sun rays to enter inside. On the contrary, if the temperatures are below 67 ºC the coating acts as an insulator preventing the sunrays from escaping out and hence keeps the rooms warmer. Apart from windows, this technology can also be applied to medical imaging and security scans. The researchers say that the technology is scalable even to large surface areas. The team filed a patent for this technology in Australia and US.
