Like is there a specific reason or is it just a design choice? Or do they have so many tall windows to let as much sunlight in as possible?
It just occurred to me since the futuristic full glass look of skyscrapers really stands out against normal building surrounding them.
In: Engineering
Doing brick, concrete or cladding systems is not really practical at skyscraper height mostly because of weight. Glass and aluminum extrusions is so much lighter and easier to get up there and install. Most of the load bearing elements of tall structures is concentrated within the building core, putting heavier materials at the perimeter could make for an unbalanced structure.
