I think the difference is that the computer suggested using nanoparticles that are just above the short range of violet light, so blocking out UV light, and... I guess it figured out the correct range for IR. I'm confused about that part myself. Because IR is longer than red, and UV is shorter than violet.
In other words, if you layered a thickness of nano particles on glass in the exact range you wanted to block, visible light would still come through, but not the offending light you want to get rid of. A bit more sophisticated that tinting I think.
