At the halfway point of the year, facility managers face a critical opportunity to evaluate and fine-tune their Building Automation Systems (BAS). At Facility Engineering Services, we understand the critical role BAS plays in maintaining operational efficiency, occupant comfort, and energy savings. That’s why we’ve compiled a list of 7 essential mid-year BAS tasks that every facility manager should prioritize.
1. HVAC Tune-Up
A mid-year HVAC tune-up is essential to maintain system efficiency during the most demanding months of the year. Summer heat places a heavy load on cooling systems, and without proper maintenance, performance can degrade rapidly. Scheduled maintenance such as checking refrigerant levels, cleaning coils, inspecting belts and motors, and verifying damper functionality help prevent breakdowns, reduce energy consumption, and extend equipment lifespan. Regular tune-ups also support consistent indoor comfort, vital for occupant satisfaction and productivity.
2. Energy Data Review
Analyzing energy usage data from the first half of the year provides valuable insights into system performance and operational trends. Identifying anomalies, peak demand periods, and inefficiencies allows facility managers to make informed adjustments to schedules, setpoints, and control strategies. This data-driven approach supports cost reduction, sustainability goals, and compliance with energy performance benchmarks.
3. IAQ Sensor Check
Indoor air quality (IAQ) sensors play an essential role in maintaining a healthy and safe environment. Over time, sensors can drift or become obstructed, leading to inaccurate readings and ineffective ventilation control. A mid-year inspection and recalibration of CO₂, humidity, and particulate sensors ensures that air quality remains within the proper thresholds. This is especially important in facilities with high occupancy or sensitive environments, where poor air quality impact health, comfort, and regulatory compliance.
4. Lighting Optimization
Lighting systems are often overlooked in BAS audits, yet they represent a significant portion of a building’s energy use. Mid-year is an ideal time to evaluate lighting schedules, occupancy sensors, and daylight harvesting systems. Adjusting these systems to reflect seasonal changes and occupancy patterns can lead to substantial energy savings. Properly optimized lighting also enhances visual comfort and supports occupant well-being, contributing to a more productive and sustainable environment.
5. Alarm Testing
Alarm systems are designed to alert facility teams to critical issues, but their effectiveness depends on regular testing and validation. A mid-year review ensures that alarms are properly configured, routed to the correct personnel, and functioning as intended. This includes testing for temperature deviations, equipment failures, and security breaches. Proactive alarm management reduces response times, minimizes downtime, and helps prevent costly damage or safety incidents.
6. System Updates
BAS software and firmware updates often include important security patches, performance enhancements, and new features. Delaying updates can expose systems to vulnerabilities and limit functionality. Mid-year is a strategic time to assess the current version of your BAS software and apply any necessary updates.
7. Network Security Audit
As building automation becomes increasingly connected to IT networks, cybersecurity has become a top priority. Because cybersecurity threats are constantly evolving, a mid-year network security audit helps identify and mitigate vulnerabilities that could be exploited. This includes reviewing user access permissions, updating credentials, verifying firewall configurations, and ensuring encryption protocols are in place. Protecting your BAS from cyber threats safeguards building operations, occupant data, and organizational reputation.
