CTBUH publishes report on "Vanity Height"

The Council on Tall Buildings and Urban Habitat published a report on what it called "vanity height"

Quote:
We noticed in Journal 2013 Issue I’s case study on Kingdom Tower, Jeddah, that a fair amount of the top of the building seemed to be an unoccupied spire. This prompted us to investigate the increasing trend towards extreme spires and other extensions of tall buildings that do not enclose usable space, and create a new term to describe this – Vanity Height, i.e., the distance between a skyscraper’s highest occupiable floor and its architectural top, as determined by CTBUH Height Criteria.



With a vanity height of nearly 124 meters within its architectural height of 321 meters, the Burj Al Arab has the highest non-occupiable-to-occupiable height ratio among completed supertalls. 39% of its height is non-occupiable.



Without vanity height, 44 of the world’s 72 "supertall" buildings (defined as more than 300 meters) would be less than 300 meters, losing their “supertall” status.

New York City has two of the top 10 tallest vanity heights in the world and the city will gain a third when the new One World Trade Center opens in 2014.

The vainest building overall is Ukraina Hotel in Moscow, Russia, with 42 percent of the building uninhabitable.

Frankly, it's their own fault for using the particular criteria that they use for official height. Once Petronas was deemed taller than Willis (then Sears), the floodgates were opened.

The ironic thing is that CTBUH criteria to define "building height" was one of the drivers of this quest for "vanity height"

I think this is a way to counterbalance the "spire counts to full height" measuring. Although it may be full height, it is vanity.

I never really cared about height or vanity. As long as the design is nice, I'm okay with it.

Well I think a lot of these buildings are like this because of the design, thats all. They didn't build this to be useless. They are for the look for the building, although Nanjing IFC and Bank of America are kind of ugly on the top, but anyway, its just for the building. WIthout it it would look really ugly.

I never realized you can't live above 600m up in Burj Kahlifa. Is that true or just no occupations yet.

The Old World Trade Center had only 1% non occupiable height. Nice.

I remember a few wonderful examples in Europe.
e.g. Sapphire Tower (with Spire 261m, 236m without), Unicredit Tower (with Spire 231m, 160m without) and Heron Tower (with Spire 230m, 202m without)

If the spire is counted on 1WTC, it will probably have one of the highest 'vanity height' counts.

I'm very glad that the CTBUH finally acknowledges the problems of its official height measurement. I hope this is the beginning of an effort to create a measurement system that is more fair and more related to the visual appearance of buildings

Btw, the roof height measurement system I proposed would limit vanity height, which has become so popular in the recent years, to a reasonable level. Here is the thread of it:

I have read the article when they published it on the website and it was quite a good read indeed. i think it is funny that china has either buildings without any spire that are far at the bottom of the chart or buildings with spires that are rather up in the graph. the only building in between with a little crown is leatop plaza. also intersting to see is that petronas is not as far up in the graph as people would think. the controversity just came up because it got a title thru that, if it wouldn't have gotten one, not many would have realized probably. also the empire state building, willis tower and one of the world trade center buildings would all have a pretty high vanity height, if the antenna's would count to overall height. so it is just that noone calls an antenna an antenna anymore and instead builds spires, which makes the graph look like it gets more and more vanity abusng buildings. But in reality it is always a big variation of all these buildings. now we have a lot of buildings with big spires in the recent years, but there are also many buildings with no spire in the recent years. also all the buildings that become supertalls because they have a spire will be in there and have a high chance of being up in the graph, whereas if they had no spire they would be not even in the graph because they do fail to reach that specific height limit we set. seeing how it will change in the coming years will be interesting though.

Agree, I've always found the official heights on that site rather dubious. The Shard's highest occupied floor is only at 244m yet it's listed as a super tall.

At least they managed to come up with a method of measuring buildings that do have spires, as opposed to the back-forth that happens on here.
