They will have no choice because they will be pressed into service for that long.
And that's the exact problem. The windows will still be "functioning" as a building skin, but they will offer such poor thermal performance over the decades that the extra energy used will be enormous.
My concern with window-wall is not its need to be eventually replaced, whether that is sooner or later. My concern is what energy suckers window-wall buildings are by nature of the inferior thermal performance of window-wall systems. One year of abundant energy use is one thing --- 50 years of excessive energy use is a painful thought.
Urban enthusiasts on UT and elsewhere harp on about how cars are so bad for the environment, but people are so willing to turn a blind eye to the vast problem of buildings' energy use.
