Retro-Commissioning

Identify and correct control, scheduling, and operational issues that prevent existing systems from performing as intended.

RESTORE SYSTEM PERFORMANCE

Existing Building Systems Can Drift From Their Original Intent

Schedules change. Setpoints get adjusted. Sensors fail. Equipment is replaced. Programming is modified. Over time, even a properly designed building can begin operating differently than intended.

CIMCO Building Solutions uses retro-commissioning to evaluate existing controls and system operation, identify performance issues, and help restore appropriate sequences and operating strategies. The objective is not simply to find faults—it is to understand how the building is actually operating and identify practical improvements that can increase reliability, comfort, and efficiency.

FIND THE PERFORMANCE GAPS

Understand How the Building Is Actually Operating

Retro-commissioning looks beyond individual service problems to examine how controls, equipment, and operating strategies work together. CBS combines system information with field observations to identify conditions affecting building performance.

Controls Review
Evaluate programming, schedules, setpoints, alarms, and sequences for potential operating issues.

System Trending
Use BAS trend data to understand equipment and system performance over time.

Field Verification
Compare information reported through the BAS with actual equipment and conditions in the facility.

Corrective Recommendations
Identify practical control adjustments and system improvements based on documented findings..

CORRECT THE CAUSE

Look Beyond the Individual Comfort Complaint

A hot room, excessive runtime, unstable temperature, or recurring alarm may be the visible symptom of a larger controls or operating issue. Simply correcting the immediate complaint does not always address the reason it occurred.

Retro-commissioning takes a broader view. CBS can evaluate system operation, control sequences, schedules, sensor information, and equipment response to help identify underlying issues and determine practical corrective actions. The result is a better understanding of how the building is operating—and where improvements can have the greatest effect.

TURN FINDINGS INTO IMPROVEMENTS

Focus on Corrective Actions That Make Operational Sense

Retro-commissioning is most valuable when findings lead to practical changes. CIMCO Building Solutions can help facility teams distinguish between programming adjustments, maintenance issues, equipment limitations, and controls upgrades that may be affecting performance.

Programming Corrections
Adjust sequences, schedules, setpoints, and control logic when operation differs from the intended strategy.

Sensor & Device Issues
Identify unreliable inputs, actuators, or field devices that are affecting system response.

Equipment Coordination
Address controls conditions that cause connected systems to operate against one another or inefficiently.

Modernization Opportunities
Identify obsolete controls or system limitations that may require a longer-term upgrade strategy.
