Energy Performance Improvement Program
Interdisciplinary Life Sciences Building (ILSB)
In collaboration with facility coordinators, the following adjustments have been made to the building:
- Calibrate sensors to modify Air Changes per Hour (ACH) according to AHSRAE Standards.
- Repaired all Enthalpy wheels, and revised the Enthalpy wheel control sequence to optimize energy performance.
- Repaired exhaust fan dampers that were causing fans to not reach setpoint and dampers that were found stuck in position.
- Repaired failed points for all fume hoods. Made mechanical modifications to 21 fume hoods to convert from CAV to VAV controls.
- Outdoor air control is now based off of classroom CO2 levels rather than hall CO2 levels.
- Modified Relief Air Flow Levels that were found to be set too high.
- Corrected synchronization issues by updating firmware on all Siemens field panels.
- Re-assigned sensors that were found to be crossed for different rooms.
