Operational and occupancy changes can challenge a commercial building’s mechanical, electrical and controls systems—which can compromise performance and efficiency. That’s why McKenney’s offers a comprehensive, systematic commissioning process for existing buildings to identify and implement cost-efficient operational and maintenance (O&M) improvements. Retrocommissioning (RCx) enables building owners to integrate critical equipment and processes to help buildings evolve as quickly as the world around them.
McKenney’s RCx offers immediate low-cost and no-cost improvements—including data collection and analysis of existing systems. It also provides capital improvement recommendations aimed at saving energy and increasing system efficiency to reduce cost and optimize operations.
RCx is a cost-effective approach to improve system performance in buildings facing problems that stem from performance degradation or design and construction issues. McKenney’s RCx identifies root causes and implements or recommends measures that will systematically improve building systems to operate more efficiently, effectively and reliably for many years. Building owners reduce costs, managers improve operations and tenants experience greater comfort.
If you had the opportunity to make an investment that could deliver a 50% return on your money, would you be interested? An independent study by the Lawrence Berkeley National Laboratory* demonstrates that commissioning is one of the most cost-effective strategies for reducing energy costs and greenhouse gas emissions in buildings today.

RCx doesn’t end when our engineers leave the building. It continues throughout the building’s lifecycle. For instance, building operator training is key to maintaining system performance. Our team provides this training and encourages the operator to participate in the RCx process to gain equipment knowledge and enhance their troubleshooting skills. Training may include walkthroughs with the commissioning team, classroom-style presentations, or even hands-on trend research and analysis. The goal is to make the operator self-sufficient to maintain equipment and respond efficiently to occupant requests.
The result of a building’s RCx analysis includes specific recommendations for reducing energy use. This can range from simple, low-cost repairs to complex, highly integrated system renovations and modifications of operational practices. One key piece of the planning phase is the review and analysis of utility bills and facility performance as compared to peer buildings. Utility data is gathered and performance is tracked to show before, during and after analysis of the RCx process effectiveness in your facility.
The comfort, health and productivity of occupants is directly tied to indoor environment quality (IEQ). From poor lighting and inconsistent temperatures to poor air circulation and ventilation, the McKenney’s RCx team conducts rigorous testing and training to help improve every aspect of the indoor environment.
A thorough, guided review of important building system documentation such as operations and maintenance manuals, operations sequences and system diagrams with the building operator is an important component of a comprehensive RCx process.
For a facility to achieve LEED Existing Building certification, it must become more energy efficient. Documentation is necessary to prove that specific guidelines have been met. This includes several related credits for monitoring energy performance, reducing overall energy use and supporting operations and maintenance plans. McKenney’s, along with the U.S. Green Building Council, recognize the important role RCx plays in making these certification efforts a reality.
The McKenney’s Commissioning Group together with our Energy Services Group has extensive experience in identifying operational issues, providing comprehensive solutions and ensuring repairs and modifications are conducted to create long-term success. Our RCx services are complemented by a wide-ranging, diverse breadth of services, refined by more than 60 years of proven mechanical engineering service and construction performance.
