About Retrocommissioning

Building Commissioning and Retrocommissioning Service Technician

Retrocommissioning (RCx) seeks ways to improve how building equipment and systems function together. It can resolve issues occurring during design or construction. It also addresses problems that have developed throughout the building’s life. We tackle these issues to improve your building’s operations and maintenance (O&M) procedures and enhance overall building performance.

Our Retrocommissioning Process

The retrocommissioning process involves developing and applying audit, review, analysis and reporting activities on an existing facility. This allows us to identify areas, systems and equipment that are no longer meeting the original design intent.

Our team of National Facility Specialists includes designers, engineers, energy auditors and building commissioning agents. All are committed to providing you with expert energy management assistance. Because of this, we offer a value-driven, practical approach to retrocommissioning. This helps us identify more efficient uses of natural resources, resulting in reduced operating costs and risks.

NFS also has expertise in retrofitting buildings, providing comprehensive lighting and energy efficiency retrofit services.

Finally, we can help you improve work environments and productivity, align with sustainability initiatives and comply with federal and state energy legislation.

Retrocommissioning FAQ

What is retro-commissioning?2020-06-30T15:19:05+00:00

Many factors can impact the overall performance of your building and equipment over the life the facility. These can include regular wear and tear, insufficient maintenance, changes to original equipment, and more. Retro-commissioning involves inspection and testing of key systems to understand the current level of functionality, provide recalibration or tune ups, pinpoint issues reducing efficiency and implement corrective measures.

What is the difference between an energy audit and retro-commissioning?2020-06-30T15:19:40+00:00

Both energy audits and retro-commissioning identify problems with key building systems. An energy audit of your facility will tell you if there is equipment in need of maintenance, repair or replacement. Energy audits also compare your utility usage to that of similar buildings in a process called ‘benchmarking’ to determine deviations from the average that may indicate a problem. Retro-commissioning takes the process one step further to include implementation of corrective measures to achieve the cost savings identified.

How does retro-commissioning or an energy audit benefit me as a building owner/operator?2020-06-30T15:36:44+00:00

Retro-commissioning and energy audits provide a strong return on investment. Research confirms that retro-commissioning delivers an average 15% annual energy savings with a payback ranging from 0.2 to 2.1 years2. Additional benefits include reduced wear and tear on equipment resulting in longer lifespans, improved reliability with decreased outages/downtime, and a healthier environment your building occupants.

What should I look for in a retro-commissioning/energy audit firm?2020-06-30T15:21:23+00:00

Open communication is crucial when seeking an energy services firm. The depth of a retro-commissioning or energy audit effort varies. The process should be tailored to meet the specific objectives, budget, or current challenges of each client. An experienced energy services provider knows the right questions to ask and listens to develop an approach that prioritizes your unique concerns and requirements.

Can retro-commissioning costs be offset by rebates or incentives?2020-06-30T15:21:57+00:00

Many utility providers across the nation offer incentives that help offset the cost of energy efficiency improvements. Retro-commissioning or an energy audit is often the first step to pinpoint areas of concern.
