A Cost-Effective Alternative to Replacements

Many older or poorly maintained buildings have veered off their intended design. This negatively impacts occupant comfort and energy consumption and puts undo stress on the facilities team.

The purpose of retro commissioning (RCx) is to identify and correct the deficiencies within a building that are preventing the building from operating as it was commissioned and designed. Once a building is retro commissioned, any energy conservation measures implemented will perform at peak efficiency due to the surrounding equipment starting from an optimized baseline.

The benefit of the RCx process is that by first identifying the deficiencies, the equipment can be repaired and refurbished, thereby achieving the same result as replacing the equipment. Unlike other companies who might recommend a “rip and replace” approach, CM3’s RCx process offers a different strategy that is industry-recognized and provides proven results.

Our Approach

Using a systematic process, our RCx specialists perform a standardized review and test of each mechanical system within your building. From that information, we determine where you are losing money based on inefficiencies. We then provide you with a comprehensive findings report and corrective action recommendations which can help reduce your energy bills and maximize occupant comfort.

• a systematic process that quickly identifies deficiencies and allows for repairs based on severity and impact.
• performed by a standardized review and test of each mechanical system.
• provides a comprehensive findings report and corrective action recommendations.
• may be eligible for utility rebates, which CM3 will help you identify and qualify for.
• Upon approval by the customer, the repairs can then be performed and the system commissioned.

The Retro-Commissioning Process

Repairs

The RCx report provides a clear path forward for system repair and enhanced energy efficiency – whether you partner with us for those repairs or choose to manage that process with internal staff.

Once the identified repairs and refurbishment are complete, the system can be commissioned to ensure that proper unit operation has been achieved.

Continuous Performance Validation (MBCx)

CM3 also offers additional monitor-based commissioning services. With this solution, repairs and unit functionality are verified and continuously monitored to ensure the building and equipment continue performing as it was commissioned.
