Reply to comment by CSyoey 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
The article implies NO, these wavelengths are ABSORBED in the coating, not reflected. The energy is then radiated back out at other wavelengths that penetrate our atmosphere.
Article is not clear, but that is my interpretation. In any case, I highly doubt it would be any worse than existing UV-blocking glass.
