BMS Maintenance: SCOPE of WORKS

System Health Review

The foundation of effective BMS maintenance is ensuring the system itself is stable, reliable, and functioning correctly.

WR8Tech performs comprehensive system health reviews including:

• BMS server and supervisor health checks
• Network communication review
• Controller status verification
• Alarm review and cleanup
• Trend logging verification
• Database integrity check
• Backup verification
• Time synchronisation review
• User access review
• License and software review

These checks ensure the system infrastructure remains stable and reliable, reducing risk and improving operational confidence.

Sensor & Field Device Review

Accurate sensors are critical to effective building control. Even small sensor inaccuracies can result in significant energy waste and comfort issues.

WR8Tech reviews and validates:

• Temperature sensors
• CO sensors
• CO₂ sensors
• Humidity sensors
• Pressure sensors
• Flow sensors
• Energy meters
• Valve and damper feedback signals
• Faulty sensor identification
• Calibration recommendations

Sensor drift is one of the most common and overlooked causes of poor building performance. Identifying and correcting these issues often delivers immediate improvements.

Control Strategy Review

Control strategies define how your building operates. Over time, control logic may become outdated or ineffective due to building changes or system modifications.

WR8Tech reviews and optimises:

• HVAC control sequences
• Economy cycle operation
• Static pressure reset optimisation
• Chilled water reset optimisation
• Heating optimisation
• Supply air temperature reset
• Plant sequencing
• Deadband optimisation
• Valve and damper control optimisation
• Simultaneous heating and cooling prevention

Optimising control strategies typically delivers 5–20% energy savings without capital expenditure.

Scheduling Optimisation

Operating schedules are one of the largest drivers of energy consumption. Buildings frequently run outside of required hours due to outdated schedules or manual overrides.

WR8Tech reviews and optimises:

• After-hours operation
• Tenant schedules
• Equipment start and stop times
• Warm-up and cool-down strategies
• Holiday scheduling
• Night purge operation
• Weekend operation
• Override management

Reducing unnecessary run time often delivers immediate energy savings and improved equipment life.

Alarm Management & Fault Detection

A well-managed alarm system ensures that critical issues are identified quickly, while nuisance alarms are removed.

WR8Tech reviews and improves:

• Nuisance alarm removal
• Critical alarm configuration
• Alarm prioritisation
• Fault detection review
• Equipment fault identification
• Communication failure review
• Sensor fault detection
• Plant fault detection

Effective alarm management improves response time and operational awareness.

Energy Performance Review

A BMS generates valuable data that can be used to improve building performance. WR8Tech uses this data to identify optimisation opportunities.

Energy performance review includes:

• HVAC energy performance review
• Base building energy analysis
• After-hours energy analysis
• Trend analytics
• Monthly performance reporting
• Seasonal performance review
• NABERS improvement opportunities
• Carbon reduction opportunities

This data-driven approach supports ongoing performance improvement.

Graphics & User Interface Improvements

Clear, effective graphics help operators understand building performance and identify issues quickly.

WR8Tech provides:

• Operator graphics review
• Dashboard improvements
• Energy dashboards
• Equipment performance dashboards
• Alarm dashboards
• Plant overview graphics
• Metering dashboards

Improved graphics support better operational decision making.
