It is known among tall-building architects that there are many tricks to increase the height of skyscrapers. But inflated skyscraper height came to the attention of the Council on Tall Buildings and Urban Habitat (CTBUH) last year after a case study suggested that the Kingdom Tower was designed with large decorative "vanity space" on top, inside of its spire, to enhance its height. Kingdom Tower, designed by Adrian Smith + Gordon Gill, is set to be the tallest tower in the world when built.
As a result, CTBUH performed a study which illustrates that large portions of some skyscrapers are actually useless space used to artificially enhance their height, Architizer reports. CTBUH created an infographic showcasing the vanity space phenomenon. Vanity space is defined as the distance between a skyscraper's highest occupiable floor and its architectural top.
Burj Khalifa, currently the tallest building on the globe, at 2,716 feet, has an 800-foot-tall unoccupied spire that accounts for nearly a third of its overall height. Ukraina Hotel in Moscow gets the award for having the largest percentage of vanity space: 42% of its 675 feet is unoccupied space.

Is the AEC industry at risk of losing its next generation leaders without better mentoring?
After two or three horrifying years for the AEC industry, we are finally seeing the makings of a turnaround. However, data developed by Kermit Baker as part of the AIA Work-on-the-Boards survey program indicates that between 17% and 22% of design firms are eliminating positions for interns and staff with less than six years of experience. This data suggests the industry is at risk of losing a large segment of its next generation of leaders if something isn't done to improve mentoring across the profession.
