RCx is a cost-effective approach to improve system performance in buildings facing problems that stem from performance degradation or design and construction issues. For more info visit http://mckenneys.com.

2. 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.

3. 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.

strategies for reducing energy costs and greenhouse gas emissions in
buildings today.

5. 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.

7. 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.

8. 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.

9. 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.

10. 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.
