Empire State Building
Opened in 1931, the Empire State Building was the first building to top 100 floors, an extraordinary milestone that only added to the mystique of this art-deco masterpiece and global icon.
Otis helped make it possible, supplying the fastest, most advanced elevators of the day. The majority featured sophisticated signal controls to govern speed and leveling. Dubbed “robot elevators,” they still needed an attendant at the time.
The owners again turned to Otis 80 years later, this time to modernize the elevators as part of a massive undertaking to reinvent the majestic tower for the 21st century – as an ideal home for tech companies and, of course, a five-star tourist destination while contributing to its sustainability.
Essentially completed in 2019, the modernization was among the largest such projects in our history – and among the most complex. Otis ReGen™ drive technology feeds electrical energy back into the building power grid during braking which can then be used to drive other equipment in the building. And with our CompassPlus® intelligent dispatching, passengers get to their destinations faster during peak travel times. We also installed three new Otis Gen2® elevators, which feature steel-reinforced polyurethane belts in place of conventional steel cables to deliver an exceptionally smooth, quiet ride.
The new Otis elevators transport 4 million visitors each year.
Quick facts about the Empire State Building
The Empire State Building took just 410 days to construct, from the setting of the tower's first steel columns on March 17, 1930, to its completion on April 11, 1931. The official opening was May 1, 1931. To date, no comparable structure has matched that rate of construction.
The Empire State Building held the title of World’s Tallest Building for nearly 40 years, until the topping out of the north tower of the original World Trade Center in New York City in 1970 – another Otis project. The iconic building has starred in dozens of movies, notably the 1933 cult classic King Kong and three romantic classics: Love Affair (1939), An Affair to Remember (1957) and Sleepless in Seattle (1993).
In 2009, the Empire State Building began undergoing a series of retrofits to improve its total energy consumption across all its equipment.
