There was (and may still be, for all I know) a similar problem with a landmark building in Los Angeles, the Walt Disney Concert Hall. The hall was designed by Frank Gehry and is clad in a series of sweeping curves of stainless steel. The cladding was originally highly polished, but the surfaces acted like those solar "ovens" one can buy for camping. Buildings nearby, particularly pricey condominiums, were subject to concentrated reflected heat from the hall and resulted in some of the sort of damage done by the London skyscraper. The solution was finally found by using grinders to create a matte finish on some of the sufaces, much to the dismay of architectural purists...
