BEMS Optimisation Checklist

General System Review

Review building occupancy patterns and update time schedules to match actual usage.
Inspect current setpoints for temperature, humidity, and pressure to ensure they align with energy efficiency goals.
Audit custom control logic for redundancies or inefficiencies and update as needed.
Analyze historical trend logs to identify patterns of excessive energy use or equipment inefficiencies.
Evaluate alarm logs for recurring faults or conditions requiring optimization.

Implement seasonal setpoint adjustments to reduce energy consumption during mild weather.
Review and optimize HVAC system start/stop times to avoid unnecessary operation.
Test demand-based control strategies (e.g., CO2 or occupancy-based ventilation) to minimize energy waste.
Adjust night setback and free cooling strategies to enhance passive energy savings.
Verify and optimize plant sequencing to ensure equipment is running at optimal load conditions.

Test control loops to ensure stable operation and eliminate excessive cycling or hunting.
Fine-tune PID control parameters to improve system responsiveness and efficiency.
Verify sensor readings and recalibrate devices to ensure accuracy in control responses.
Optimize deadbands to avoid unnecessary heating and cooling conflicts.
Check override settings and return any manually overridden equipment to automatic control where appropriate.

Review graphical user interface layouts to ensure ease of monitoring and diagnosis.
Add or adjust trend logs for key performance metrics, including energy use, setpoints, and system outputs.
Ensure data points are labeled clearly and consistently for quick interpretation.
Verify live data streams and address any lags or inconsistencies.

Test communication between devices (e.g., controllers, sensors, actuators) to ensure reliable data exchange.
Review network topology for bottlenecks or unnecessary latency and address as needed.
Ensure all devices are running the latest stable firmware to improve performance and security.
Test remote access functionality to ensure uninterrupted monitoring capabilities.

Verify the efficiency of boilers, chillers, and heat pumps by analyzing trends and checking modulation levels.
Optimize fan and pump speeds via VSDs to align with actual demand.
Check air and water flow rates to ensure they match design specifications.
Inspect dampers and valves for proper modulation and seal integrity to prevent energy losses.
Implement plant rotation schedules to evenly distribute wear and extend equipment lifespan.

Analyze energy meter data for spikes or irregularities and investigate root causes.
Ensure sub-metering is properly configured to monitor specific equipment or areas.
Generate reports on energy performance and identify trends for further optimization.
Benchmark building energy use against industry standards or previous performance.
Recommend actionable changes based on insights from energy data analysis.

Ensure all peripheral devices (sensors, actuators, switches) are operating accurately to enable optimized control.
Train facilities management staff on energy-saving techniques and system operation.
Engage occupants with feedback on energy performance and comfort to encourage energy-efficient behavior.
Schedule regular system reviews to maintain optimal performance and align with changing building needs.
