Reply to comment by Onequestion0110 in Researchers designed a transparent window coating that could lower the temperature inside buildings, without expending a single watt of energy. This cooler may lead to an annual energy saving of up to 86.3 MJ/m² or 24 kWh/m² in hot climates by mossadnik

Wonder if it could be sandwiched between two panes of glass to help with durability. That way the coating has no exposure to the elements.

Kinda like a windshield? Except i think those are plastic or something sandwiching the middle glass

Uv blocking poly. Mostly for structural integrity. Uv and what not is just a bonus.

Normal glass is 2 or 3 layers often filled argon gas between them. put This on the outside of the middle layer, its protected from the harsh environment and could be in a mostly inert atmosphere.

Hopefully it doesn’t break down just due to UV.

Would suck to have yellowed completely unrepairable windows.

They have double paned windows, guessing the air acts as an insulator, dont see why we couldn't add a material inbetween that.

Indeed window companies do this. They’re called “Low E” (Low emissivity) coatings and do a great job
