  • It's one of the world's most famous buildings.

  • Constructed during the onset of  the Great Depression, the Empire  

  • State Building becamesymbol of American innovation  

  • and a marker of what the United States could  achieve, even during its darkest times.

  • Standing as the world's tallest  building for 40 years of its life,  

  • the grandeur and scale of the Empire  State inspired near-universal awe  

  • and cemented it as the defining  structure of New York City.

  • Now, as the structure  approaches its 90th birthday,  

  • a ten-year modernisation programme  has revamped the groundbreaking  

  • Otis elevator system that enabled the  original construction of the building,  

  • improved energy efficiency and brought this  iconic 1930s skyscraper into the 21st century.

  • The early 20th century was a time of  great innovation and change across the  

  • United States - and advancements in building  materials combined with a booming economy and  

  • growing population gave rise to the skyscraper.

  • First appearing in Chicago and then across the US,  

  • perhaps no American city sawgreater transformation than New York.

  • Taking the title ofworld's tallest  buildingfrom itself no less than five  

  • times between 1909 and 1931, New York City's  race for the skies captivated onlookers  

  • as taller and taller skyscrapers  began to dominate the skyline.

  • But the crash of 1929 brought this boom to an  

  • end and the demand for tall  buildings evaporated overnight.

  • With two years of planning behind themdevelopers at the Empire State decided  

  • to proceed with their project, fearing the even  greater losses that would come with cancellation.

  • Starting in 1930 and completing in just 14 months,  

  • the skyscraper set new records; becoming  the tallest structure ever built,  

  • the first building to surpass 100 storeys and  housing the world's fastest elevators of the day;  

  • an innovative installation by Otis that  made the building's immense height viable.

  • Though it's since been eclipsed  by dozens of taller structures,  

  • the Empire State's form and observation  decks, along with countless appearances  

  • across popular culture, have retained its status  as one of the world's most famous buildings.

  • Today, 90 years after its arrival on the skyline,  

  • the Empire State Building is a global leader  in sustainability and energy efficiency.

  • After a decade-long project to upgradethe building has improved efficiency,  

  • retrofitted interiors and overhauled  the Observatory Experience.

  • Each of the building's 6,514 windows have  been retrofitted with high-performance glass  

  • and a new lighting system that  adapts to the levels of natural  

  • light entering the floor-plate has been installed.

  • The heating system has been fitted with reflective  barriers to reduce heat loss and lower the  

  • building's carbon footprint while a multi-year  elevator upgrade - undertaken by the original  

  • system installers Otis - will move passengers 50%  faster during peak times than the original system,  

  • while returning energy to the building's  grid through its regenerative drives.

  • But while many of these upgrades will be  systematic and make the Empire State one  

  • of the most historic skyscrapers to achieveLEED Gold certification, the most noticeable  

  • transformations for visitors will be found  throughout the Observatory Experience.

  • The Empire State Building has remained one of  New York's most popular attractions with over  

  • four million annual visitors - and the  new upgrades help it retain that position.

  • Greeted by a new entrance lobbyvisitors will now make their way  

  • through an interactive museum to the  first viewing level on the 80th Floor.

  • This level gives visitors their first glance of  

  • the views they'll have on the  famous 86th Floor Observatory.

  • From there, a custom-built glass elevator by  Otis takes visitors to the renovated 102nd-Floor,  

  • giving them a never-before-seen look at the  inside of the building's mast on the way.

  • Seeking to make the 16-storey ride an experience  in itself, Otis used its innovative Gen2 elevator  

  • system, eliminating the need for a lift motor  room and other mechanical equipment within the  

  • confined space of the mast structure and giving  visitors unobstructed views as they travel.

  • Using less energy than roped systems  and improving passenger comfort with  

  • a steel-reinforced polyurethane belt that  cuts noise and vibration, the Gen2's small  

  • footprint makes it an ideal choice for the  confined spaces within unique structures.

  • The Gen2 system removed the need for a basement  motor room at Seoul's 555-metre Lotte World Tower,  

  • transports guests at the Armani Hotel and  penthouses inside the Burj Khalifathe world's  

  • current tallest building - and even takes visitors  to the base of Brazil's Christ the Redeemer statue  

  • - another iconic landmark that was completed  in the same year as the Empire State Building.

  • In fact, as maximising space has becomecommon goal in buildings around the world,  

  • the Gen2 system has become the most  popular elevator in Otis' history,  

  • despite only coming to the market in 2000.

  • To date, more than a million units have been sold.

  • From its base to its summit, the Empire State  Building has undergone one of the largest  

  • modernisation programs of any skyscraper to datesetting new benchmarks for energy efficiency while  

  • retaining the historic style that has made  it one of the world's most famous buildings.

  • While the wordiconicmay  perhaps be overused these days,  

  • the Empire State Building is  truly deserving of the adjective;  

  • a timeless symbol of New York City that  can now endure long into the future.
