550 Tenth Avenue, New York, NY

Automated Airflow Balancing for Sustainable Living: eFlow-Constant Airflow Regulators at the Core of NYC’s Future Tower

In the midst of the bustling construction activity at 550 Tenth Avenue, a groundbreaking innovation is set to take place with the installation of over 1,000 eFlow-Constant Airflow Regulator assemblies. Positioned to redefine indoor air quality management within this forthcoming architectural masterpiece, these regulators represent a pivotal advancement in sustainable living. Designed by Handel Architects and developed by Gotham Organization and Goldman Sachs, this residential project is not only a beacon of luxury but also a testament to a vision driven by sustainability and innovation. With a meticulous emphasis on automated airflow balancing, energy efficiency, and superior indoor air quality, 550 Tenth Avenue aims to set new standards for urban living in the heart of New York City.

At 520 feet tall and spanning 47 stories, 550 Tenth Avenue is not just a residential tower; it’s a testament to forward-thinking design and environmental stewardship. With a total development cost of $373 million, every aspect of the project is meticulously planned to ensure both luxury and sustainability. One of the key features driving this vision is the integration of eFlow-Constant Airflow Regulators, set to be installed throughout the building.

At the core of eFlow-Constant Airflow Regulators is their ability to automatically balance airflow, ensuring optimal ventilation in every corner of the tower. By dynamically adjusting airflow rates based on real-time conditions, these regulators not only enhance indoor air quality but also contribute to significant energy savings. This automated system eliminates the need for manual adjustments, maximizing efficiency while minimizing environmental impact.

Moreover, the implementation of eFlow-Constant Airflow Regulators underscores the project’s commitment to sustainability. By reducing energy consumption and minimizing the carbon footprint associated with heating, ventilation, and air conditioning (HVAC) systems, these regulators play a pivotal role in creating a more eco-friendly living environment.

As construction progresses towards completion in late 2024, the benefits of eFlow-Constant Airflow Regulators become increasingly apparent. Residents can look forward to a healthier, more comfortable living space, where indoor air quality is optimized, and energy costs are reduced. This focus on sustainability not only aligns with global environmental goals but also reflects a commitment to enhancing the quality of life for future generations.

In a city where innovation is celebrated and sustainability is paramount, 550 Tenth Avenue emerges as a shining example of progress. With eFlow-Constant Airflow Regulators at its core, this residential tower represents a bold step towards a greener, more sustainable future in the heart of New York City. Moreover, with over 450 residences, including nearly 140 dedicated to moderate/middle-income residents, and two podium floors dedicated to Covenant House, New York City’s largest provider serving youth experiencing homelessness, it is not just a symbol of luxury, but also of inclusivity and social responsibility. As the skyline evolves, so too does the standard for urban living, with automated airflow balancing paving the way for a brighter tomorrow.


Installation of eFlow-Products was undertaken by Martin Associates. The manufacturers representative, SRS Enterprises, Inc,  facilitated the sale of eFlow products for this project.
