CTBUH Height Categories Illustrated: A Comparative Analysis of Willis Tower and Petronas Towers
This infographic provides a detailed visual comparison of the CTBUH height categories through the examples of Willis Tower and Petronas Towers. It illustrates not only the overall architectural height of each skyscraper but also breaks down their heights into functional (highest occupied floor) and vanity heights (excess height). The percentage of vanity height relative to architectural height is displayed to highlight the impact of non-functional elements in skyscraper design.
By showcasing the different height measurements according to CTBUH standards, this infographic demonstrates how skyscrapers like Willis Tower and Petronas Towers are categorized and the significance of vanity heights in their total height calculations.
