American Copper Buildings

New York, USA

The American Copper Buildings development is aiming to be a ‘best in business’ market-rate residential construction project. The complex will comprise of two towers rising 41 and 48 stories respectively. The towers will be connected with a fully glazed sky bridge that offers a breathtaking view of New York City.


The development team made a firm commitment to set unprecedented standards in market-rate residential construction. The building also needed to be developed with precautions against floods and extreme weather caused by climate change due to its proximity to the East River.

In response to the client’s brief, our engineers devised state of the art systems to support the seamless running of the building.

Independent zone controls between living areas and bedrooms will be provided as standard, improving the comfort of occupants and reducing energy waste. We also advised using a displacement ventilation system within the 8-story breezeway to ensure the constant stream of fresh air required to maintain a superior level of quality in this expansive space. The entire MEP network will be provided via a centralized system that is easy for service staff to monitor and maintain.

To optimize the energy efficiency of the development our MEP engineers worked closely with our facade team to integrate solutions that would improve the performance of the building envelope, determining optimal window to wall ratio, U-value (rate of heat loss or gain), and solar orientation of the towers. The latest security technology will also be installed for the safety of residents.
