Apparently the archetects in London hadn't heard of the Vdara Death Ray.
Employees have called the phenomenon the "Vdara death ray" ... The architect, Rafael Viñoly, also designed the "Walkie-Talkie" skyscraper which has been dubbed the "Walkie-Scorchie" due to a similar problem.
Ania Gzik, an insurance worker, said she couldn't believe how hot the spot became when the light was reflected and plans to warm up there when winter comes
They have done this sort of thing beforehttp://www.nottinghamplayhouse.co.uk/about-us/sky-mirror/
A £900,000 mirror sculpture destined for a square in Nottingham, UK, will have to be shielded to prevent it focusing the Sun's rays and barbecuing passing birds.
Contrary to media speculation Sky Mirror does not pose any danger to thepublic or pigeons in the form of a barbecue ray.

My mother was intrigued by a line of tiny holes that appeared in her curtains. Turned out to be burn marks from the sun shining through her collection of glass paperweight

How much of light is reflected by a single pane of glass? I'm sure there are many factors including whether it has a privacy coating. If the building has about 30 panes x 30 panes, that gives about 900 panes of glass. If they would all be focused on a single focal point, that would be 900 suns x the reflectivity. The amount of sunlight reflected may depend on the angle. With a very clear window glass, it may only be a couple of percent. With a mirrored glass, perhaps up to 50% or more.One may be able to just change either the vertical or the horizontal angles of the windows to break up the reflection, and limit the multipliers.. Another solution to the problem might be to get as clear as possible of windows for the building.to limit the amount of sunlight reflected by each pane.
Perhaps you could give it the bomber look.
... complex curvature mural on a massive scale
Coat the windows with a material that would disperse the reflected sunlight.
Eliminate the reflectivity — sounds reasonable *
