About the Project
This Steele Hall project, completed in Dec. 2018, is a great example of collaboration between Dartmouth's capital renewal and energy management teams. Originally conceived as a capital renewal project stemming from the need to repair failed steam heating coils in the building air handling units and a need to update the laboratory-air control systems, an integrated project was developed to address the capital renewal needs and incorporate several innovative and effective energy conservation measures. Highlights of the project include:
- Update laboratory exhaust/ventilation control systems and reduce airflow quantities where possible and appropriate.
- Replace failed steam heating coils in the building air handlers.
- Modify the existing lab exhaust heat recovery system to optimize the recovery efficiency of the system.
- Convert the building heating system from steam to low-temperature hot water (110°F), allowing incorporation of heat pump chillers.
- Install heat pump chillers to efficiently produce heating and cooling simultaneously and reduce demand on the campus central pla
