Why don't we cover roofs with those retroreflective beads embedded in pavement paint? Wouldn't that reflect even more?

- HPsquared 5y agoRetroreflectors focus their reflection specifically in the direction of the light sources using reflection and/or refraction, which involves some losses. I'd expect retroreflectors to sacrifice total brightness/emissivity in favour of directionality. Probably better to just have a reflective surface (mirror finish perhaps?)
