Retro-commissioning software that does the investigation for you
The hardest part of retro-commissioning isn't the fixing. It's the finding.
Built for firms that deliver commissioning, not just buildings that receive it
Here's how companies can improve their retro commissioning services by using PEAK:
Cross-vendor from day one
Multi-client visibility
Prioritised by impact, not noise
Verification that closes the loop
What it looks like when the loop closes
Data-driven workflow drives a speedy AHU fix
A fault diagnosed from trend data and resolved in days - without a diagnostic site visit.
Read the story →Rectifying overnight operation
The classic retro-commissioning finding - plant running out of hours - caught, fixed and verified through PEAK.
Read the story →Anomaly detection catches post-project drift
The drift that erases RCx savings - caught because monitoring continued after the project ended.
Read the story →Across the industry, organisations running continuous fault detection and diagnostics achieve a median 8% energy saving (Lawrence Berkeley National Laboratory, 550 buildings). PEAK is rated 4.8 on Capterra.
Turn a one-off project into a standing service
Retro-commissioning has a built-in expiry date: performance drifts the day the engagement ends. That is bad for the building - and worse for your revenue model, because it makes RCx a procurement event instead of a relationship.
With PEAK staying connected after handover, your RCx project becomes the on-ramp to monitoring-based commissioning: continuous fault detection, a review cadence you own, and verified savings your client can report year after year. Your firm moves from selling investigations to operating a service - recurring revenue for you, sustained performance for them.
The engagement delivers real savings - then performance drifts the day the monitoring stops, and the value quietly erodes until the next procurement cycle.
The firm that turned commissioning projects into a platform business
Aero Performance Group, a division of the Hill Group based in Chicago, has been one of the leading retro-commissioning and MBCx providers in the ComEd utility program since it began - and has saved its clients more than $26.5M in energy costs. Before PEAK, its engineers reviewed BMS data manually. On PEAK, Aero runs commissioning across its US portfolio from one platform: faults surface automatically, savings are verified for utility incentive claims, and fixed-term projects keep converting into long-term engagements.
“The platform’s real-time monitoring, powerful FDD, client-friendly dashboards, and exceptional support from the CIM team have helped us to scale quickly, improve client engagement, and maintain a high standard of operational excellence across our growing portfolio.”
Daniel Hosko, Commissioning Manager, Aero Performance Group
Frequently asked questions
Does PEAK replace the RCx engineer?
No. PEAK does the data work - detection, diagnosis, prioritisation and verification. The engineering judgement, client relationship and implementation remain yours. Firms use it to redeploy engineering hours from investigation to resolution.
Does it work on old or mixed-vendor BMS estates?
Yes - that is the normal case, not the exception. Serial networks are bridged with a router, closed systems are reached through a gateway or vendor interface, and read-only access means no control-system risk. An old BMS usually means more findings, not fewer.
How fast is a building connected?
Typically two to eight weeks from data access to a meaningful first fault list, depending on BMS accessibility and point naming quality. Subsequent buildings in a portfolio connect faster.
What is the difference between RCx with PEAK and monitoring-based commissioning?
Retro-commissioning is the point-in-time engagement; monitoring-based commissioning is what it becomes when the monitoring stays on. PEAK supports both - most partners start with an RCx project and transition the client to a continuous service. Read the complete MBCx guide.
