McKenney’s, Inc. Retrocommissioning (RCx) - A comprehensive, systems-based approach to improve building operations
Operational and occupancy changes can challenge a commercial building’smechanical, electrical and controls systems—which can compromiseperformance and efficiency. That’s why McKenney’s offers acomprehensive, systematic commissioning process for existing buildings toidentify and implement cost-efficient operational and maintenance (O&M)improvements. Retrocommissioning (RCx) enables building owners tointegrate critical equipment and processes to help buildings evolve asquickly 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 providescapital improvement recommendations aimed at saving energy andincreasing system efficiency to reduce cost and optimize operations.

McKenney’s RCxidentifies root causes and implements orrecommends measures that willsystematically improve building systemsto operate more efficiently, effectivelyand reliably for many years. Buildingowners reduce costs, managers improveoperations and tenants experiencegreater comfort.

RCx doesn’t end when our engineers leave the building. It continuesthroughout the building’s lifecycle. For instance, building operatortraining is key to maintaining system performance. Our team providesthis training and encourages the operator to participate in the RCxprocess to gain equipment knowledge and enhance theirtroubleshooting skills. Training may include walkthroughs with thecommissioning team, classroom-style presentations, or evenhands-on trend research and analysis. The goal is to make the operatorself-sufficient to maintain equipment and respond efficiently tooccupant requests.
The result of a building’s RCx analysis includes specificrecommendations for reducing energy use. This can range from simple,low-cost repairs to complex, highly integrated system renovations andmodifications of operational practices.One key piece of the planning phase is the review and analysis of utilitybills and facility performance as compared to peer buildings. Utilitydata is gathered and performance is tracked to show before, duringand after analysis of the RCx process effectiveness in your facility.
The comfort, health and productivity of occupants is directly tied toindoor environment quality (IEQ). From poor lighting and inconsistenttemperatures to poor air circulation and ventilation, the McKenney’sRCx team conducts rigorous testing and training to help improve everyaspect of the indoor environment.A thorough, guided review of important building systemdocumentation such as operations and maintenance manuals,operations sequences and system diagrams with the building operatoris an important component of a comprehensive RCx process.
For a facility to achieve LEED ExistingBuilding certification, it must becomemore energy efficient. Documentationis necessary to prove that specificguidelines have been met. Thisincludes several related credits formonitoring energy performance,reducing overall energy use andsupporting operations andmaintenance plans. McKenney’s,along with the U.S. Green BuildingCouncil, recognize the important roleRCx plays in making these certificationefforts a reality.
The McKenney’s Commissioning Group together with our EnergyServices Group has extensive experience in identifying operationalissues, providing comprehensive solutions and ensuring repairs andmodifications are conducted to create long-term success. Our RCxservices are complemented by a wide-ranging, diverse breadth ofservices, refined by more than 60 years of proven mechanicalengineering service and construction performance.
