Energy Efficiency Retrofit
Washington Houses, a 14-story building with 151 affordable housing units, originally built in 1954, recently completed a comprehensive energy efficiency retrofit as part of its ongoing modernization initiative. eFlow worked directly with Restore Services Inc. (RSI) to install 4-inch eFlow-Constant Airflow Regulators (CARs), enhancing ventilation and optimizing energy usage throughout the building. These upgrades have significantly improved indoor air quality while reducing energy costs, aligning with NYCHA‘s commitment to modernizing public housing infrastructure.
Project Background
Washington Houses is a part of the New York City Housing Authority (NYCHA), North America’s largest public housing authority, established to provide affordable housing for low and moderate-income residents.
Project Details
The 14-story building underwent a retrofit, modernizing its systems to improve energy efficiency and air quality for residents. The project highlights NYCHA’s ongoing commitment to upgrading affordable housing infrastructure.
Technical Insights
The retrofit included the installation of 4” eFlow Constant Airflow Regulators (CARs), supplied directly to contractor Restore Services Inc (RSI). These CARs regulate airflow to optimize energy usage and improve indoor air quality throughout the building.
Benefits of Installing eFlow CARs
- Improved Indoor Air Quality: Consistent airflow helps reduce contaminants.
- Energy Efficiency: Enhances system performance while lowering operational costs.
- Enhanced Comfort: Balances air distribution, ensuring a healthier living environment for all residents.
Conclusion
Washington Houses exemplifies how public housing projects can effectively integrate modern energy solutions while preserving affordability. Using eFlow Constant Airflow Regulators, the retrofit improves air quality and energy savings, setting a model for future NYCHA projects.

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.
