Super-thin coating has been developed by researchers to keep buildings cool in summer

It is quite hard to keep a large building cool during summer when temperature is really high. The building soaks up heat from outside and building dwellers also have to deal with heat generated from inside. Due to combination of both sources of heat, air conditions need to be turned on for a long time to handle all of it. Some Researchers from Stanford University has created a new solution for this issue to keep things cool in hot summer. They have created a super thin coating that will radiate heat from inside and reflect the sunlight by 97%. Researchers are calling this new technique photonic radiating cooling.

The material consists of total 8 layers and is just 1.8 micros thick. Seven layers of the coating consist of silicon dioxide and hafnium oxide over a thin layer of silver. Though the new technique seems quite good and its implementation can be quite effective, but still it is nowhere near commercial use yet. The main issue is that the current prototype is hardly a size of a personal pizza, which means it cannot be applied in a real-world scenario. However, the good news is that the current production facility has enough capability to create enough photonic radiating cooling to achieve desired results.
