In FY25, the Retrocommissioning teams worked on the following buildings:

Loomis Laboratory of Physics

The retrocommissioning project focused on optimizing the building's complex HVAC systems that serve both research laboratories and educational spaces. A significant portion of the energy savings came from implementing occupancy based controls and optimizing airflow management. The team addressed critical issues with AHU operations, including fixing broken dampers and valves that were causing energy waste. The addition of CO2 sensors and humidity controls improved indoor air quality while reducing unnecessary conditioning. The project also resolved makeup air issues affecting the Materials Research Laboratory connection, improving overall building pressure management. The hot water system improvements included fixing differential pressure control issues and maintaining proper expansion tank pressure. Steam radiator controls were enhanced with the planned addition of automated isolation valves. Controller replacements and network communication fixes eliminated operational inefficiencies and improved system reliability.
