Ruppert House Apartments, 1779 2nd Ave, New York, NY: Energy Retrofit for Enhanced Air Quality
Ruppert House Apartments, located at 1779 2nd Ave in New York City, is a 42-story affordable housing complex built in 1973. Recently, the building underwent a comprehensive energy efficiency retrofit, aimed at improving air quality and reducing energy consumption in collaboration with RSI(Restore Services Inc.), eFlow USA installed 3” eFlow-Constant Airflow Regulators (CARs) set at 20 and 25 CFM, providing balanced ventilation in every apartment.
Project Background
Ruppert House, subsidized by the federal government through HUD (Housing and Urban Development), serves as low-income family housing. The building’s recent retrofit reflects a commitment to modernizing affordable housing infrastructure while enhancing living conditions.
Project Details
The 42-story building underwent a retrofit that included the installation of eFlow-Constant Airflow Regulators to address issues related to ventilation and energy efficiency. By incorporating eFlow-CARs, the project helped improve indoor air quality and optimize energy usage throughout the building.
Technical Insights
The retrofit featured the installation of 3” eFlow-CARs set at 20 and 25 CFM in each apartment exhaust. These CARs ensure consistent airflow, automatically balancing ventilation, thus improving indoor air quality and reducing energy costs.

eFlow-CAR FACTS
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.
