Architecture: Delete "tower" type?

The CTBUH defines a tower as having less than 50% of the height occupied. As we have kept the tower type, could we add this as a definition to the description of the tower type?

I doubt we would have much data for percentage of height occupied, so limited use in adding that as a property to tower.

From this page, yes, I guess it is a bit esoteric, most would simply do measurements from roof and spire heights and argue from there.

"The CTBUH ranks the height of buildings using four different methods:

Height to architectural top of the building. This is the main criterion under which the CTBUH ranks the height of buildings. Height measurements begin at sidewalk and run to the top of the building, inclusive of spires but excluding items such as flag poles or antennas.
To highest occupied floor: Height to the floor of the highest occupied floor of the building.
To top of roof: Height to the top of the roof.
To tip of spire/antenna: Height to the tip of spire, pinnacle, antenna, mast or flag pole. [edit] Tallest database The CTBUH maintains an extensive database of the tallest buildings in the world, organized by various categories. Buildings under construction are also included, although not ranked until completion."

I guess we could use the emporis standards: http://standards.emporis.com/?nav=realestate&lng=3&esn=81731 I'm just not sure this level of detail is necessary. Wikipedia articles don't seem to dwell on this particular detail. The emporis standard seems to mirror what sprocketonline is asserting: a maintenance/plant floor doesn't count. I guess this is interesting from the financial point of view, I'm not sure how it fits in to the pissing match aspect of all of this: asserting who is the tallest. Show me the data! Do you have oodles of data for this that is just waiting for a slot in the schema?

I assume occupied height is measured to the floor level of the occupied space? (and not to the ceiling/roof above it)

If to the floor level, for any building with an inaccessible roof (i.e. no roof top terrace, and ignoring access for maintenance and cleaning), the occupied height of a building will be different from the building height (measure to the top of the superstructure , excluding antennae and spires). As most tall buildings have an unoccupied plant room on the topmost level, the difference can be significant.

In theory occupied height belongs on building, although in practice it's probably only recorded for skyscrapers.

There is "Structural Height" on structure and "Height with Antenna" on skyscraper. There is note on the former saying "For Skyscrapers this should not include antennae or spires." So I guess I'm implying that the former means occupied height. Maybe it would make more sense to have it be the other way around, but I think the bottom line is: people only care about this distinction with skyscrapers and I've given them the slots to describe it so good enough? I could add occupied height to skyscraper, but then what should they put in for "Structural Height" ?

A missing property that seems of interest amongst the height-loving skyscraper-o-philes is Occupied floor height.

Highest possible terrestrial-structure-based human viewing spot is the Occupied floor height.

Could be placed within /Structure or /Skyscraper (former makes the most sense as it already has the related roof height).
