eFlow-Constant Airflow Regulators Enhance Air Quality and Energy Efficiency at Boulevard Senior Center

The Boulevard Senior Center located at 726 Stanley Ave, Brooklyn, NY has undergone an impressive retrofit project aimed at improving air quality and energy efficiency. As part of this endeavor, eFlow-Constant Airflow Regulators (CARs) have been installed throughout the facility. These innovative devices play a vital role in creating a healthier and more sustainable living environment for the residents.

The Boulevard Senior Center, a part of the New York City Housing Authority (NYCHA), provides affordable housing to low- and moderate-income New Yorkers. Although specific details about the building’s characteristics are limited, the retrofit project holds great promise for its future.

The key component of this project is the installation of eFlow-Constant Airflow Regulators (CARs). These 4″ CARs, set to 45 CFM, offer automatic airflow balancing capabilities. They continuously adjust the airflow in response to changes in static pressure, ensuring a well-balanced ventilation system throughout the building. This eliminates the need for manual adjustments, saving time and effort for the building’s management.

The installation of eFlow CARs also brings notable benefits to the Boulevard Senior Center. The CARs contribute to substantial energy savings. By maintaining optimal airflow levels, they prevent excessive air supply and exhaust, resulting in reduced energy consumption and utility costs. This energy-efficient approach not only benefits the environment but also promotes financial savings for the facility. Moreover, eFlow CARs significantly enhance indoor air quality within the building. By ensuring proper ventilation, they effectively reduce the risk of pollutants, allergens, and stagnant air accumulation. This creates a healthier and more comfortable living environment for the residents, supporting their overall well-being.

eFlow worked directly with RSI Remediation Specialists Inc (RSI), a trusted installer, to ensure the seamless integration of their CARs throughout the facility.

The retrofit project at Boulevard Senior Center serves as a remarkable example of combining affordable housing with initiatives focused on air quality and energy efficiency. Through the integration of eFlow CARs, the center is poised to provide its residents with balanced airflow, energy savings, high indoor air quality, and overall energy efficiency. This project sets a positive precedent for similar endeavors and demonstrates the commitment of all involved to prioritize the well-being of the Boulevard Senior Center’s residents.



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.
