Building Management System Upgrade, Intermittent Air Conditioning Shutdowns

Facilities Engineering and Infrastructure and an authorized vendor will perform phased Building Management System upgrades in Pavilion B
- The Building Management System (BMS) controls the heating and cooling in the building and ensures that temperatures and humidity stay within acceptable ranges while also decreasing energy consumption
Existing controls will be replaced with new controls and sensors to improve system reliability and long‑term maintainability
Work will occur over multiple weekends to minimize weekday operational impact
Only one air conditioning unit will be intermittently affected at a time
- Each affected unit will experience approximately 3 to 4 shutdown intervals per day, lasting 20 minutes to up to 1 hour per interval
Additional air conditioning units serving each area will remain operational to maintain comfortable building temperatures
Affected units can be operated in manual mode if needed
Facilities Engineering will actively monitor environmental conditions to maintain patient and staff comfort
Planned weekend phasing:
- May 9 – May 10:
  - AC‑2B intermittently affected
  - AC‑1B, AC‑3B, and AC‑4B remain operational
  - Imaging on the 1st floor remains open and supported by additional cooling
- May 16 – May 17:
