McKenney's offers a comprehensive retrocommissioning (RCX) process designed to improve the performance and efficiency of existing buildings by identifying and implementing cost-effective operational and maintenance improvements. This approach not only enhances energy efficiency and reduces operational costs but also contributes to overall occupant comfort and satisfaction. With proven results from various projects, McKenney's emphasizes the long-term value and profitability of integrating RCX into building management strategies.

2. ENHANCE PERFORMANCE,
EXCEED EXPECTATIONS
Operational and occupancy changes can challenge a commercial building’s mechan-
ical, electrical and controls systems—which can compromise performance and
efficiency. That’s why McKenney’s offers a comprehensive, systematic commission-
ing 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.

Make the smart choice
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.

the RCx process to gain equipment knowledge and enhance their troubleshooting skills.
Training may include walkthroughs with the commissioning team, classroom-style pre-
sentations, or even hands-on trend research and analysis. The goal is to make the opera-
tor self-sufficient to maintain equipment and respond efficiently to occupant requests.
Save energy, save money
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.
Enhance the environment
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.
Be prepared
A thorough, guided review of important building system documentation such as opera-
tions and maintenance manuals, operations sequences and system diagrams with the
building operator is an important component of a comprehensive RCx process.
