Visual Overview of 2018’s Top 10 Tallest Buildings in the U.S.

Since the dawn of time, man has aspired to great heights. Historically, tall structures were reserved for great rulers, religions and empires, but as technologies and techniques improved, towers began to spring up to celebrate our culture, promote our cities, or simply to show off.

Modern skyscrapers are a result of many factors. Technological advancement, like the invention of the elevator, allowed buildings to rise even higher into the sky. Economic factors, like the 1973 oil crisis, paved the way for greener and more sustainable buildings, leading to some of today’s certifications like the EPA’s ENERGY STAR or USGBC’s LEED certification. And, of course, learning from tragedies, such as the June 14, 2017 Grenfell Tower fire in London or the 2010 blaze in Shanghai helped to propel safety to its highest levels for all those working and living in today’s modern towers.

The above infographic, based on data from the Council on Tall Buildings and Urban Habitat, displays the 10 tallest buildings in the U.S. that have been completed as of January 2018. Nine of the top 10 tallest contain office space. Out of these, six are office space only while three are mixed-use. There is only one tower fully consumed by residential space. Eight of these giants have steel as a main building component - half of those are a composite mix of steel and concrete. Stats from the Energy Star and USGBC’s websites indicate that four of the top 10 have been awarded the an ENERGY STAR rating and eight either have or are currently seeking LEED certification.

One World Trade Center

Location: New York City
Height (m/ft): 541.3 m / 1,776 ft

Completed in 2014, this office skyscraper is the highest building in the U.S with 94 floors and replaces almost one quarter of the total office space lost on September 11, 2001. The building materials are a composite of reinforced concrete in the core and steel in both the columns and floor spanning. One World Trade Center carries a LEED Gold rating and is an ENERGY STAR labeled facility. There are 73 elevators housed in One World Trade Center with the top speed reaching 10.16 m/s, or nearly 23 mph, making them the fastest elevators in the U.S.

In 2014, the building achieved LEED Silver certification and it is also carries an ENERGY STAR label. The office workers that call this building home work across 83 floors and may soon have a sky-high exterior elevator to a new observation deck to brag about.

The Salesforce Tower might reside in the shadows of skyscrapers in New York or Chicago, but in San Francisco, it ranks as the city’s tallest building. It was officially completed in 2018, making it the newest of the top 10 tallest buildings in the U.S. Spanning 61 floors of office space, the tower’s core is composed of reinforced concrete while the columns and floor spanning are both steel. LEED Platinum pre-certification was awarded to the Salesforce Tower in January of 2014.

As cities and populations around the globe continue to grow, along with technological and safety advancements, it is expected that bigger and more elaborate towers will dot our skylines. Dario Trabucco, Research Manager of the Council on Tall Buildings and Urban Habitat (CTBUH), suggests that modern skyscrapers may no longer be standalone structures, but instead might be interconnected on higher floors - allowing “much more redundancy in terms of energy and water supply, as well as secondary escape and rescue routes.” Could the future hold multi-tower buildings stretched across the landscape, all interconnected and accessible with elevators that don’t only go vertical, but horizontal as well? Will the top 10 tallest buildings discussed above soon be overshadowed by new behomeths? Only time will tell!
