Positive Feedback Commissioning
Positive Feedback Commissioning (PFCx®) is an automated, ongoing process developed and trademarked by RS&H to proactively identify and resolve issues in order to ensure a facility continues to operate at optimal efficiency. PFCx provides a building owner with a real-time picture of energy usage, rather than a one-time snapshot captured by traditional commissioning services.
In PFCx, the RS&H commissioning authority remotely monitors the performance of critical systems through sub-metering, building automation systems, and utility data. A departure from normal operation generates an automatic notification triggering RS&H to investigate the issue and work with the building owner and operations and maintenance staff to initiate corrective actions.
