Anyways, why not take it to the spire/antenna threads. This should be for 1 WTC.
This took 3 seconds.
The CTBUH ranks the height of buildings using three different methods:
1. Height to architectural top of the building. This is the main criterion under which the CTBUH ranks the height of buildings. Heights are measured from the level of the lowest, significant, open-air, pedestrian entrance to the top of the building, inclusive of spires but excluding items such as flag poles or antennae.
2. To highest occupied floor: Height to the floor of the highest occupied floor of the building.
3. To tip of spire/antenna: Height to the tip of spire, pinnacle, antenna, mast or flag pole.
So it looks like that the antenna/spire height is in fact the correct distinction.
Anyway, I will take this to another forum, even though I believe it is a valid topic for the 1WTC page.
