I believe not, with that section the height should be over 1500ft.

Looks like 4 or 5 panes on the first row of slotted glass on the SE side was placed today. The pace should pick up soon, though.

Okay well either way it surpassed it, thats all that matters. I knew it was 1,454 but for some reason many sources still say 1,472 so I just took the higher end

Yeah, I probably should have used a little common sense before posting that, huh?

Why did they put the mechanical levels at the top rather than the bottom. Surely if they used the top for office they could demand higher rents?

The floor space is too small for proper offices at that height.

I don't think it's the floor space.

That isn't it at all. There is no large central plant for the tower itself as there was for the twin towers. There is a smaller plant for the memorial/hub. That is how they got away with the relatively small bands of mechanical floors on those. Tower One needs to be self-sufficient now in that regard.

I'll let Otie or PMad chime in with the technical reason. I just assume fresh air comes in the top/bottom and the "dirty" air is shot out the other end.

That, and it would take a lot more energy to move water from the base to the top than from holding tanks down. Also, the transformers are closer to the floors they serve. The air thing is also true, but in more ways than you'd think. Even though there are vents at the west side of the memorial plaza and in the pavilion, there are also huge inlets and outlets serving the NW corner of the site under street level in the lower mechanical floors. The tower's HVAC system also takes in a lot of outside air (~10% average in the US). The kitchen smoke is released out the top [pretty sure]. There are also additional rain water storage tanks for flushing toilets and supporting the plaza trees, according to early informational diagram. There will also be generators/battery banks, more likely the first. Basically, it localizes the utilities for the upper half of the tower for logistical reasons. There are countless more reasons, but that should give a basic idea.

Also, if you look at the old designs, the office space is at the bottom with a large crown on top, they wanted to keep people safe on the bottom floors.

Everytime I see 2WTC in a diagram, I want a 1WTC sized version, the design is just so timeless aka Chrysler.

Great progress.
