I'd assume they're going to install AC anyway, because who wants to be in NYC in the summer without it.

So the extra utility of big views etc outweighs running the AC a bit more.

A large floor area in a tall building means windows can only exist on the perimeter and almost definitely can't open for ventilation. Also the larger the floor, the more natural light the windows have to allow in and the more heat from the Sun they'll trap. In that space there will be lots of computers, screens, and lots of other electrical systems (even just for the lighting) generating a lot of heat.

So HVAC is anyway needed for the building to operate properly and the people to be comfortable even before you factor in the outside climate.

I'd assume that more insulation and less insolation would make that A/C a lot cheaper and less polluting to operate.
