Reply to comment by soks86 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

Very true. Though it may redistribute it somewhat. Slightly more down onto surfaces within the window's reflection, and less on the tops of buildings where a/c units generally are. Though again, all very minimal changes.

Well that might reduce comfort at the street level in dense downtown areas. Huh... although larger buildings actually take cold and pass it down (no compressed gas pipes going the length of skyscrapers as leaks would be hell to fix and probably dangerous overall) that doesn't change the effect of letting the heat off of the windows build up between buildings while the insides of the buildings bring less cool air to the base.

Electric cars to the rescue!
