We used to call it the "World's Tallest Plywood Structure" because they would replace the broken windows with plywood boards. Interesting story behind the problem with the design. The building is a narrow near parallelogram (two pairs of parallel sides that are not right angles). The wind would twist the building a bit and crack the windows, then they would pop out. Even more interesting, as part of the review of the structure, they found it was more vulnerable to toppling in a major disaster over its narrow sides than the broader ones. I forget if the fix was to go to or from single panes.
