BeMS Performance Optimisation
Independent BeMS Performance Optimisation That Works With Your Existing Contractor
Most Building Energy Management Systems perform well when first commissioned. Over time, buildings change, occupancy evolves and operating strategies drift. Zerith provides an independent engineering review that works collaboratively with your incumbent BeMS contractor.
We start before we touch the controls.
Every project begins with a complimentary half-day desktop review — understanding how the building was intended to operate before assessing how it performs today.
What we review
Description of Operation
Control philosophy
Energy data
BeMS graphics
Previous optimisation reports
Metering information
Building use
Trend logs
What that delivers
Better first discussions
Faster mobilisation
Early opportunity ID
Better targeted investigations
More valuable recommendations
Collaboration before criticism.
Our role is not to replace or criticise your incumbent BeMS contractor. We provide an independent engineering perspective that complements their expertise.
By working collaboratively, we avoid unnecessary conflict, encourage open technical discussion and achieve better outcomes.
We work with your contractor, not around them
The Zerith BeMS Methodology
A structured, non-adversarial process
1
Review Documentation
Description of Operation, control philosophy, graphics, points, alarms, schedules.
2
Review Live Head-End
Plant status, setpoints, schedules, alarms, trends, sequencing.
3
Validate Performance
Spot-check air/water temps, occupant comfort, terminal performance.
4
Positive Challenge
Raise engineering questions with the incumbent contractor first.
5
Recommend Improvements
Only after understanding strategy, operation and contractor rationale

The Commercial Benefit
Improvements your existing contractor can often deliver
Our collaborative approach frequently identifies improvements that can be delivered by the existing contractor as part of their maintenance obligations, or via low-cost daywork instructions.
Reduces consultancy costs
Delivers practical savings
Speeds implementation
Maintains contractor relationships
Frequently Asked Questions
What building owners ask us about BeMS reviews
Will this create conflict with our existing controls contractor?
No — our whole methodology is built around collaboration, not criticism. We raise questions with your contractor before drawing conclusions, and often deliver findings jointly.
What kind of savings can we expect?
Savings depend on how far current operation has drifted from original design intent — your free desktop review will indicate the likely scale of opportunity for your specific building.
How often should a BeMS be reviewed?
Building use, occupancy and operating strategies drift over time, so periodic reviews — and our Continuous Optimisation option with seasonal reviews — help catch drift before it becomes costly.
Will this disrupt building operations?
Our review process is designed around desktop analysis, head-end review and targeted spot-checks — minimising on-site disruption to occupants and operations.
Do you work with all BeMS platforms?
Our engineering approach is platform-independent, focused on control philosophy and building performance rather than any single manufacturer's system.
Who implements the recommended changes?
Often your existing contractor, as part of maintenance obligations or low-cost daywork — that's a deliberate part of our commercial approach, not an afterthought.
