Bank of America Tower Charlotte, US

For most people, "use the elevators" might seem like a surprising instruction in an emergency. But, at Bank of America Tower, emergency evacuation elevators equipped with "Occupant Evacuation Operation" (OEO) uses elevators to evacuate people quickly and safely. This landmark tower is in rapidly growing Charlotte, North Carolina. The safety of the city’s future passengers is in our hands, as we help build its tallest buildings with the latest tech.

Project highlights

OEO – getting people out faster

Everyone knows that taking the elevator in a high-rise building is usually faster than the stairs, especially for less mobile people who might also slow down movement in a crowded stairwell. Occupant Evacuation Operation (OEO) technology uses the elevator system to manage the efficient and safe evacuation of people in high-rise buildings. When OEO is activated in an emergency, building occupants are directed to assemble in fireproof landing areas and then guided by live messaging signage to specific emergency-equipped elevator cars. Given the significant cultural change in asking people to jump on an elevator when the alarms are going off, occupant training and communication are essential to ensure the entire process proceeds smoothly. Industry studies show that OEO allows for up to 50% faster evacuation in comparison to using the stairs exclusively. OEO is also safer and more secure, especially for less-mobile building occupants.

Technology like OEO is essential in creating safer and more sustainable cities. Christopher Mason, a 34-year Schindler veteran and tech guru, helped to develop OEO for the entire industry, starting in 2009. Changes were made to high-rise building safety protocols in the International Building Code following lessons learned from 9/11. Today, any building over 420 feet (128.02m) in the USA must have OEO-enabled elevators or an additional emergency stairwell. Mason consulted on the OEO installation at Bank of America Tower, Schindler’s pioneering OEO project in the USA. Mason believes that in future many more buildings will feature OEO, as its benefits get more widely recognized and accepted. "Eventually people will ask, ‘Why doesn’t this building have elevator evacuation operation?’," he says.

OEO controls and monitoring systems for emergency responders and building management provide clear communications - and of course a classic red American emergency phone.

Real-world adjustment

New tech nearly always requires new solutions. Our client asked for state-of-the-art OEO technology and sustainable operation in the LEED Gold certified building. The elevators at Bank of America Tower regenerate power as they descend, feeding it back to the building grid, a signature Schindler sustainability feature. OEO testing revealed that too much energy could cause a power overload during an emergency operation.

To address this, our Schindler team worked closely with the general contractor and the building’s electrical design team to eliminate potential power surges, thus ensuring the elevators run smoothly when operating on the emergency generators. Bank of America Tower is the perfect synthesis of emerging technology and real-world conditions.

Building the city of Charlotte

Small and medium cities like Charlotte are booming all across America, proving a viable alternative to sprawling metropolises. We are happy to contribute to this growth, in Charlotte and beyond. The Bank of America Tower is part of the Legacy Union development, a new center for Charlotte. Bank of America Tower is just the beginning. This 33-story skyscraper is capped with a 30-meter LED lit-glass pyramid – a beacon for Charlotte.

Cities get built building by building, and buildings are built floor by floor. We have increased our Schindler Charlotte install teams from six to 26 in less than five years as we helped our clients build the city. We are developing local expertise for even the most demanding projects, which will continue to shape cities like Charlotte for many more years to come.

We are witnessing significant population growth and economic expansion in cities like Charlotte. These new urban centers provide improved quality of life that leverages new technologies and new ways of thinking. Schindler is thrilled to be leading the way with innovative, safety-oriented vertical transportation solutions for progressive clients like Bank of America.
