Innovative Airflow Management: Installing eFlow-Constant Airflow Regulators in 4720 Third Avenue, Bronx, NY

This nine-story residential building, designed by the esteemed Ismael Leyva Architects, is not just another development; it represents a fusion of modern design and sustainable practices. One of the key elements enhancing its sustainability profile is the integration of eFlow-Constant Airflow Regulators (CARs) throughout the building. 4720 Third Avenue is a dynamic project that aims to meet the diverse needs of the community. It features a mix of 165 market rate and affordable residential units spread across nine floors. Additionally, the building incorporates two stories of retail space, ensuring a vibrant streetscape that caters to both residents and visitors alike.

The installation of eFlow-Constant Airflow Regulators (CARs) is a strategic choice in the design of 4720 Third Avenue. These innovative devices are poised to revolutionize the building’s ventilation system, offering precise control over airflow while maximizing energy efficiency. Here are some key benefits that these regulators bring to the project:

-Energy Savings: eFlow-CARs ensure that ventilation systems operate at optimal efficiency by automatically adjusting airflow rates to match real-time conditions. This results in reduced energy consumption and lowers utility costs over the lifespan of the building.

-Consistent Ventilation: Maintaining a steady airflow is crucial for indoor air quality and occupant comfort. eFlow-CARs provide a constant volume of air regardless of changes in system pressures, ensuring consistent ventilation levels throughout the building.

-Compliance and Safety: Proper ventilation is essential for compliance with building codes and standards related to indoor air quality. eFlow-CARs help achieve and maintain compliance, contributing to a healthier and safer living environment.

-Noise Reduction: Traditional airflow control methods often result in noisy systems. eFlow-CARs mitigate this issue by stabilizing airflow and reducing turbulence, resulting in quieter operation and enhanced occupant comfort.

As 4720 Third Avenue nears completion, it stands as a testament to the possibilities of harmonizing architectural excellence with environmental responsibility. The integration of eFlow-CARs underscores the project’s dedication to achieving superior indoor air quality and energy performance—a vision that will positively impact the community and inspire future developments.

Installation of eFlow-Products was undertaken by TRV Mechanical.
