Generally speaking: Not without severe quality of life impacts… and dismantling of what few laws we have around that.
Think of the last hotel you saw versus the last office building. Feel free to go check out google maps if you need to.
Back? Cool. You know how the hotel is a weird shape? Maybe it is a narrow rectangle. Maybe you are pretty gosh darned certain it is actually a swastika from above. Whatever. And you know how that office building is a big ass fat rectangle, or even a square?
Yeah. There are severe implications of that. Hotels tend to be “long and narrow” because… you need to make sure every unit has a window. Whereas offices can either have a lot of windowless rooms or a centralized cube farm (or, if you are in a fancy company, an atrium).
Which is the problem. Plumbing can be rerouted. Even drop ceilings can be removed/resolved. HVAC can be rebalanced. But significant portions of those office buildings are just not habitable.
And a lot of those “you need a window” are mostly based in fire safety laws that were learned at great cost to human life. But they also very much contribute to quality of life.
And this is also why a lot of the retrofitted buildings on the east coast tend to be more “luxury condos”. You sell someone a quarter of a floor and they deal with the hvac issues. Which will help but… not that much.
