Did you hear about that curved building in London that reflected light so well you could cook an egg in the street a block away? I think you could make an argument for white surfaces to reflect light into buildings but full blown mirrors are probably a fire hazard.
You'd want to run captured light through a diffuser anyway.
Which is what they did at 20 Fenchurch.
20 Fenchurch. It melted car plastics.
I don't think it would be such an issue witn flat mirrors. The curvature focuses light into a single point much like a magnifying glass.
Vegas had a death ray building too.
