A Hospitality Retrofit for Energy Efficiency
Project Background
Hampton Inn Dulles South, located in Chantilly, VA, is a 7-story, 137-room hotel undergoing a significant retrofit aimed at improving energy efficiency and indoor air quality. As part of the project, eFlow collaborated directly with property management company B.F. Saul Property Co. to install custom Constant Airflow Regulators (CARs) for optimized ventilation in every guest room.
Project Details
The retrofit focused on upgrading the hotel’s HVAC system to ensure consistent airflow and energy savings. Each guest room was equipped with 4” eFlow-CARs set to 50 CFM in 6″x4″ Mounting Plate Assemblies for exhaust applications, ensuring the hotel’s air quality remains high while minimizing energy use. The use of eFlow-CARs in the hospitality industry underscores the importance of guest comfort, efficient ventilation, and sustainability in modern hotels.
Technical Insights
The 4” eFlow-CARs installed in every room were tailored to meet the unique needs of the hotel environment. These Constant Airflow Regulators automatically adjust to ensure balanced ventilation, maintaining high indoor air quality while optimizing energy consumption.
Benefits of Installing eFlow CARs
- Energy Efficiency: By regulating airflow, CARs reduce energy waste and contribute to operational cost savings.
- Improved Air Quality: The balanced ventilation system eliminates pollutants and maintains consistent air quality throughout the hotel.
- Enhanced Guest Comfort: Guests benefit from a quiet, comfortable environment with well-regulated airflow, making for a more pleasant stay.
Conclusion
The retrofit of Hampton Inn Dulles South demonstrates how advanced ventilation solutions, such as eFlow -Constant Airflow Regulators, can enhance energy efficiency and air quality in hospitality projects. This initiative reflects a growing trend towards sustainable, energy-efficient practices in modern hotels.

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.
