CASE STUDY: BMS Field Services & Performance Optimization

Category: BMS Field Services / Smart Building Maintenance

Client Type: [Commercial Project]

Location: [Dubai, UAE]

The Challenge

Over time, even the most sophisticated Building Management Systems (BMS) encounter “performance drift.” Our client reported inconsistent zone temperatures, frequent false alarms, and energy bills that were steadily climbing. The issue wasn’t the software—it was the field level. Sensors were out of calibration, and actuators were failing to respond correctly to commands, leading to massive energy waste and mechanical strain.

The GESS Solution

GESS deployed a specialized field engineering team to conduct a comprehensive BMS Lifecycle Audit. We moved beyond the control room to ensure every physical component was communicating and performing at 100% accuracy.

Precision Field Calibration: We performed NIST-traceable calibration on temperature, humidity, and $CO_2$ sensors to ensure the “brain” of the building was receiving accurate data.
Actuator & Valve Overhaul: Detailed physical inspection and testing of dampers and valve actuators to ensure airtight seals and precise flow control.
PID Loop Tuning: Re-stabilized the system’s control logic to prevent “hunting”—a common issue where fans and pumps cycle unnecessarily, leading to premature equipment failure.
Network Health Check: Diagnostic testing of the MS/TP and IP communication trunks to eliminate data packet loss and improve system response times.

Project Impact & Results

Key Performance Indicator	Improvement
Data Accuracy	98% increase in sensor reliability post-calibration
Operational Savings	18% reduction in HVAC energy consumption
System Stability	65% decrease in nuisance alarms and manual overrides
Equipment Life	Estimated 2-3 year extension of AHU and Chiller lifespans

The GESS Advantage
