✅ What is a BMS?
A Building Management System (BMS) is an integrated control system that monitors, controls, and records critical facility parameters to maintain compliance and ensure product quality.
🎯 Key Objectives
- Maintain environmental conditions (temperature, humidity, pressure differentials).
- Ensure regulatory compliance (GMP, EU Annex 1, FDA).
- Enable real-time monitoring and alarms.
- Support data integrity and electronic records (Audit Trail, 21 CFR Part 11).
- Optimize energy efficiency and operations.
🛠️ Main Functions
✅ HVAC control (air handling units, cleanroom conditions)
✅ Environmental monitoring (temperature, humidity, pressure)
✅ Utilities monitoring (chillers, boilers, compressed air)
✅ Alarm management and notifications
✅ Data logging and reporting
✅ Integration with Building Automation Systems (BAS) and SCADA
🧪 Typical BMS Parameters in Pharma
- Room Temperature & Humidity
- Differential Pressure Between Zones
- Airflow and Filter Status
- Equipment Status
- Utility Supply Conditions
- Access Control Interfaces
🔹 Regulatory Expectations
- Qualification & Validation: IQ/OQ/PQ of the BMS.
- Alarm Management: Timely response and documented actions.
- Data Integrity: Secure storage, audit trails, electronic signatures.
- Change Control: For any modifications to BMS configurations.
