Stanford scientists have created a system that can dissipate heat during the day through reflective panels on the roof of the building. This system could lead to a revolutionary decrease in energy consumption in cities.
Releasing some data than others related to electricity consumption, even in the United States 15% is allocated to maintaining refrigeration systems in buildings, which is an excessive cost for the environment and the environment. Without any doubt, it would be a great advance for electricity consumption if this revolutionary new system were to see the light of day.
In order for this passive cooling system to function, a temperature needs to be maintained below ambient temperature levels. This passive system has been demonstrated using a technique known as radiative cooling, which means that a device exposed to sunlight is used to radiating heat to the outside through a transparent window into the atmosphere. This allows the temperature of a room to be reduced by 5 degrees.
What has been achieved it is a kind of radiator that also happens to be an excellent mirror. The multi-material layer is 1,8 microns thick and consists of silicon dioxide and hafnium oxide on top of a thin layer of silver. The internal structure allows infrared radiation to be reflected at a frequency that allows it to pass through the atmosphere without heating the air surrounding the building.
When exposed to direct sunlight, this passive system decrease the temperature by 5 degrees Celsius demonstrating these results what could be a technology that would allow energy efficiency. An interesting proposal to improve quality of life and that would help current air conditioning systems buildings not to overload them.
