As the political center of the United States, Washington, D.C., boasts a diverse range of building types. The following locations are suitable for installing ERV (Energy Recovery Ventilation) systems, 

incorporating a technologically advanced design:

1. High-end Commercial and Hospitality Buildings

The Park Hyatt Hotel: Its guest rooms feature a "bright and airy" design, basalt bathrooms, and American Craftsman decor. This makes it suitable for a concealed ERV system, maintaining both aesthetics and air quality.

Office Buildings and Conference Centers: Glass-walled buildings require efficient ventilation. ERV systems balance energy consumption with air exchange requirements, making them 

particularly suitable for high-density office spaces.

2. Historic Building Renovation Projects

Buildings near the Capitol: These buildings must comply with heritage preservation requirements. The miniaturized design of ERV systems (such as concealed ducting) can meet ventilation 

needs while avoiding damage to the original structure.

3. Healthcare and Educational Institutions

Hospitals and Laboratories: These locations have stringent air quality requirements. ERV systems filter out harmful gases and maintain stable temperature and humidity, making them ideal for 

operating rooms or research areas.

University Campuses: For example, George Washington University requires low-noise ventilation in densely populated classrooms. The quiet nature of ERV systems meets these requirements.

4. High-Tech Residential Case Studies

Modern villas and apartments utilize a "top-supply, top-return" air duct layout. The ERV unit can be installed in the ceiling and paired with an intelligent control system for automated management.
