eFlow-Constant Airflow Regulator (CAR’s) were installed in parts of American Express headquarters building in order to combat unbalanced ventilation and bad odor concerns.
3″ CARs at 25 CFM were installed for controlled exhaust and 6″ CARs at 130 CFM were used for fresh air supply. Mounting plate transitions were utilized for both applications.
200 Vesey Street, also known as the American Express Tower, is one of four towers that comprise the Brookfield Place complex in the Financial District of Lower Manhattan in New York City. The building is an example of postmodern architecture, as designed by Cesar Pelli & Associates, and contains over 2.1 million square feet of rentable office area.
This building suffered sever damage by the falling debris when the World Trade Center towers collapsed on September 11, 2001. The building had to be closed for repairs from September 11, 2001 until May 2002 as a result of damage sustained in the terrorist attacks.
200 Vesey Street holds LEED Gold certificate.
WB Engineers is responsible for mechanical updates, including specification of constant airflow regulators (CAR’s) to address unbalanced ventilation concerns.
Installation of eFlow-CAR was undertaken by Cannon Mechanical.
eFlow-CAR is a simple solution to balancing ventilation systems. Constant Airflow Regulator is a device that automatically regulates airflows in ventilation systems to constant levels. The passive control element responds to duct pressure, and requires no electric sensors, pneumatic sensors or controls. eFlow-CARs promote high indoor air quality and energy savings.
