System and plant context
Map the available BMS architecture, connected services, interfaces, meters, sensors and control points around how the building is actually used.
Existing BMS and BEMS
Find what your BMS is missing.
Optim Energy reviews how your existing building management system is configured, documented and used. We identify faults, avoidable energy use and practical improvements, then help verify what changed.
Technology-neutral · Defined scope · Nationwide in Ireland
Useful without a replacement
The review stands on its own, even when the right answer is to retain and improve the existing system.
Action, not another shelf report
Findings become agreed changes, owners, priorities and a practical sequence for improvement.
Evidence after the change
Available trend and energy data are used to check whether the intended result appeared.
Review scope
See the system as part of the building
A useful review connects BMS configuration with plant behaviour, energy use, operating hours and the people responsible for action.
Schedules and control logic
Review operating hours, optimum start and stop, setpoints, deadbands, sequencing, weather compensation, overrides and suitable control routines.
Sensors, alarms and trends
Check available sensor behaviour, point naming, alarm usefulness, trend history and whether the system provides evidence an operator can act on.
Energy and operating waste
Investigate out-of-hours operation, simultaneous heating and cooling, persistent overrides, abnormal cycling, baseload and other visible sources of avoidable use.
Documentation and operation
Assess control descriptions, drawings, point lists, maintenance information, access arrangements and how operators currently investigate and resolve issues.
Improvement and verification
Prioritise immediate corrections and longer-term work, then use the available BMS and energy data to check whether agreed changes produced the intended result.
How it works
A controlled route from inspection to improvement
The scope reflects the system, access and operating risks. We agree what can be inspected and changed before work begins.
-
Step 01
Qualify and scope
We begin with the building type, BMS make and model, connected services, known problems, available data and the people who operate or maintain the system.
-
Step 02
Review the system
We inspect the agreed BMS evidence and operating context on site and, where appropriate, through available trend and remote-access information.
-
Step 03
Optimise what is safe
With written authority, we can make agreed low-risk adjustments. Original settings and changes are recorded, with specialist or vendor coordination where required.
-
Step 04
Report and verify
You receive a prioritised action plan and a record of findings and changes. One follow-up review normally checks the available trend and energy evidence after four to six weeks.
Your deliverable
A report built for decisions and follow-through
You own the agreed review report. It separates what can be corrected now from work that needs planning, investment, vendor access or another competent specialist.
Recommendations remain technology-neutral. If Optim EOS could close a demonstrated capability gap, we explain why. It is not the predetermined outcome of the review.
- Executive summary for the responsible owner or management team
- System, access and documentation gaps
- Faults, control issues and visible sources of energy waste
- Change log for agreed adjustments completed during the review
- Immediate corrective actions with ownership and dependencies
- Prioritised improvement and upgrade recommendations
- Risks, constraints and items requiring a competent specialist
- 30-, 90- and 180-day action plan
- One follow-up verification using available trend and energy data
Responsible by design
Access, authority and safety stay explicit
Access shapes the answer
Engineering access, point lists, control descriptions, drawings, trend history, energy data and maintenance records improve the review. Missing inputs are documented as limitations rather than hidden assumptions.
Changes need approval
Agreed low-risk changes require written authority and a change log. Safety-critical programming, unsupported proprietary work and plant-maintenance responsibility remain outside scope unless separately agreed with the relevant specialists.
Savings are site-specific
Results depend on the system condition, connected plant, occupancy, access and which actions are implemented. Any site-specific estimate states its assumptions and proposed verification method.
Possible project support
Where SEAI BMS Optimisation may apply
SEAI currently describes BMS Optimisation support of up to €2,000 or 50% for a qualifying specialist review and optimisation of an existing BMS. This service may align with that measure where the project, provider and applicant meet SEAI's current requirements.
Eligibility, provider requirements, approval and payment are determined by SEAI. Confirm the current position before relying on grant support or committing expenditure.

BMS review questions, answered
What is a BMS performance review?
A BMS performance review examines how an existing building management system or building energy management system is configured, documented and used. Optim Energy reviews the available architecture, connected services, sensors, meters, schedules, setpoints, overrides, alarms, control sequences, trends and operating practices to identify faults, avoidable energy use and practical improvements.
Does Optim Energy replace our existing BMS?
Not automatically. The review is technology-neutral and useful as a standalone service. Optim Energy may recommend retaining and improving the current system, coordinating work with its incumbent vendor, or adding capability where a demonstrated monitoring or control gap exists. Optim EOS is one possible recommendation, not a predetermined outcome.
Can Optim Energy change BMS settings during the review?
Agreed low-risk changes such as suitable schedule, setpoint or alarm adjustments may be made with written authority and a recorded change log. Original settings are recorded where access permits. Safety-critical programming, unsupported proprietary changes and work outside the agreed operating limits require separate scope and the relevant competent specialist.
What do we receive after the review?
The agreed deliverable normally includes an executive summary, system and documentation gaps, faults and energy-waste findings, a record of changes made, immediate corrective actions, prioritised upgrades, risks and dependencies, and a 30-, 90- and 180-day action plan. One follow-up verification using the available trend and energy data is normally included.
What information is needed before a BMS review?
Useful inputs include the BMS make and model, login and engineering access, point lists, control descriptions, drawings, trend history, utility or meter data, operating hours, maintenance records and known issues. Missing information does not always prevent a review, but it can limit the conclusions or require vendor coordination or separately scoped data-enablement work.
Can an Optim Energy BMS review receive an SEAI grant?
The service may align with SEAI's BMS Optimisation measure where the project, provider and applicant meet SEAI's current requirements. SEAI currently describes support of up to €2,000 or 50% for a qualifying review and optimisation of an existing BMS. Eligibility, provider requirements, approval and payment are determined by SEAI and should be confirmed before relying on grant support.
How much does a BMS performance review cost?
Optim Energy scopes each review according to the system size, connected services, available data, site access, vendor involvement and required follow-up. After a qualification call and review of the available system information, Optim Energy provides a defined scope and proposal.
