4self-contained HVAC units replaced using a right-sizing strategy
2,500 sq. ft. of mechanical space upgraded within an occupied academic building
0 downtimefor classrooms, dining, and assembly spaces during replacement
100% integration with the existing proprietary BAS following commissioning
ABOUT THE PROJECT
Our team partnered with American University to replace aging self-contained HVAC units in a continuously occupied academic building on the university’s Washington, DC campus. The goal was to upgrade HVAC infrastructure while maintaining uninterrupted ventilation and comfort for classrooms, a cafeteria, and an auditorium. The project required a right-sizing replacement approach within tight mechanical spaces and strict scheduling constraints tied to the academic calendar.
OUR SOLUTION
We provided mechanical engineering and commissioning services, including:
- Analyzing the building and the impact of prior infrastructure projects on central systems, allowing us to right-size new units to improve system performance while reducing construction costs.
- Designing a unit replacement of four water-cooled self-contained units located in compact mechanical rooms at the building core, keeping existing ductwork and system layouts.
- Evaluating and documenting rigging paths through corridors, doorways, and elevators to ensure new equipment could be delivered and installed in modular sections.
- Coordinating closely with the university and contractor to phase installation during extended weekends and academic breaks.
- Integrating new units, sensors, and sequences of operation into the university’s existing proprietary Building Automation System (BAS), in collaboration with the BAS integrator.
- Performing full commissioning in accordance with university standards to verify system performance.
THE IMPACT
The HVAC upgrade was completed without disrupting academic activities. Indoor air quality and occupant comfort were maintained throughout the project, while extending the building’s service life to support ongoing teaching and learning
