An incomplete operating picture
Bills, meters, building systems, equipment and condition records live in different places, making it hard to see what is happening across the site or estate.
Optim EOS · Energy Operating System · BEMS
See what needs attention. Improve what matters.
Optim EOS is Optim Energy's building-performance platform, delivered technically as a Building Energy Management System (BEMS). It brings selected site data into one operating view so teams can understand what changed, take appropriate action and verify the result.
Start with one recurring site problem and one measurable outcome.

The Challenge
Physical sites generate data. Responsible teams need answers.
The challenge is not simply collecting more readings or adding another dashboard. It is turning selected energy, equipment, condition, utility and site-activity data into clear priorities, owned action and measurable improvement.
Performance without context
Energy data alone cannot explain whether demand follows occupancy, weather, indoor conditions, production or service activity, opening hours or equipment operation.
Slow operational response
Drift, unusual demand and out-of-range conditions can persist until someone notices a bill, complaint or equipment problem, with no clear record of who is responding.
Evidence spread across teams
Facilities, operations, production, energy, sustainability and compliance stakeholders may need dependable records, but manual collection makes review and reporting harder.
Optim EOS creates one configured operating workflow for the buildings, physical-site systems and priorities in scope.

Built around the work your site team does.
Optim EOS is configured around the questions, systems and responsibilities that matter at each building or physical site, not around a fixed device bundle.
Understand
Understand what is happening
Organise performance from portfolio and site level down to buildings, systems, circuits and equipment. Relate resource use to the conditions, equipment state and production or service activity that help explain it.
- Estate, site, building and equipment views
- Whole-site, circuit and appliance energy detail
- Occupancy, indoor conditions, utilities, equipment and activity context
- Period and site comparison using retained history
Prioritise and own
Turn readings into owned action
Use site-tuned alarms and severity to show what needs attention. Responsible users can acknowledge ownership, investigate the related history and follow the condition through to resolution.
- Site-specific thresholds and alarm severity
- Device, condition, time and status in one list
- Acknowledgement that records who is responding
- Active and historic alarms for follow-up
Control
Move from insight to suitable control
Connect appropriate loads and plant so authorised teams can act remotely and agreed routines can run automatically within the site's technical and operational limits.
- Remote switching of compatible loads
- Heating, cooling, ventilation and lighting routines
- Schedules, occupancy-led operation and setbacks
- Defined limits, permissions and manual overrides
Verify and document
Check whether the response worked
Compare the agreed measure with its baseline or operating expectation after a change, then retain the evidence needed for review, reporting and the next improvement.
- Review against an agreed baseline or expectation
- Time-stamped history and configurable dashboards
- CSV, XLS and REST API access for analysis or integration
- Evidence that supports, rather than replaces, professional assessment
How it connects
One operational layer across mixed site systems.
Optim EOS can work alongside suitable existing meters, building systems, plant and process interfaces, then fill evidence or control gaps with appropriate meters, sensors, gateways and controllers. Authorised systems can also use EOS time-series data through CSV, XLS or the REST API. Each architecture is engineered for the site.
Sensors
Capture the agreed energy, utility, environmental and operational data from suitable new or existing meters, sensors and systems in scope.
Controllers
Turn insight into authorised action through compatible controllers, configured rules, operating limits and manual overrides.
Gateways
Connect field devices and compatible building or site systems to Optim EOS without requiring wholesale replacement of existing infrastructure.

Getting Started
Configured around your site, not a fixed bundle.
A site may begin with a bounded monitoring problem, then add control and automation as the evidence, technical suitability and operating confidence develop.
01
Define one useful outcome
Start with a recurring site problem, the person responsible, the available evidence and one primary measure of success.
02
Design the operating view
Agree metering, sensing, integrations, dashboards, alerts and any suitable controls for the scope.
03
Connect and commission
Install and integrate the agreed equipment, verify data quality and controls, and orient authorised users.
04
Verify and improve
Compare the agreed measure with its baseline or operating expectation, refine the response and expand only where the evidence supports it.
Sustainability and compliance
Better processes begin with dependable evidence.
Optim EOS retains time-stamped energy, environmental and operational data. Where this replaces separate manual extracts, dashboards, history, exports and API access can reduce repeated evidence collection and support baselines, sustainability reporting, internal governance, investigations and applicable compliance work.
The platform contributes operational evidence; it does not by itself certify a building or physical site, demonstrate compliance or replace the assessment and judgement of appropriately qualified professionals.

Common Questions
Optim EOS FAQ
How Optim EOS fits existing sites and estates, expands from monitoring to suitable control and makes operational data usable.
Who is Optim EOS designed for?
Optim EOS is Optim Energy's building-performance platform, delivered technically as a Building Energy Management System (BEMS). It is designed for organisations responsible for commercial, public-service and industrial buildings or physical sites. A deployment can serve one site or a multi-building estate, with views relevant to owners, facilities, operations, production, energy, sustainability, quality and compliance teams.
Does Optim EOS replace an existing BMS?
Not necessarily. Optim EOS can work alongside compatible existing building systems and add meters, sensors, gateways or controls where there are evidence or control gaps. In some buildings it may become the principal operating view; in others it complements systems already in place. Integration is confirmed during technical design, and authorised external systems can use EOS time-series data through CSV, XLS or the REST API.
Is Optim EOS another dashboard?
The dashboard is one part of the product. Optim EOS is configured as an operating workflow around selected site data, site-tuned alarms, response ownership, suitable controls, retained history and an agreed measure of improvement. Optim Energy also designs, commissions, supports and tunes the deployment.
Can we begin with monitoring and add control later?
Yes. A deployment can begin with visibility, alarms and evidence, then add compatible controls and approved automation as priorities, technical suitability and operating confidence develop.
What can Optim EOS monitor?
Depending on the configured deployment, Optim EOS can bring together whole-site, circuit and equipment energy; equipment state; temperature and humidity; CO₂ and other indoor-condition readings; anonymous presence or footfall counts; door state; water and other relevant utility signals; and selected product, storage, process, production or service context.
What can Optim EOS control and automate?
Optim EOS can remotely switch compatible loads and apply configured schedules or rules to suitable connected equipment. Examples include out-of-hours setbacks, occupancy-led ventilation or lighting, open-door response and peak-load management. The final scope depends on the equipment, technical design, operating authority and required safeguards.
Can it support more than one building?
Yes. Optim EOS can organise information across an estate and allow teams to move from portfolio and site comparison into building, system, circuit or equipment detail. Each site can retain its own dashboards, thresholds and operating rules.
Can we use the data outside Optim EOS?
Yes. Time-series data can be reviewed through the browser interface, exported from widgets in CSV or XLS format, and made available for machine-to-machine integration through the Optim EOS REST API.
Does Optim EOS make a building compliant?
No platform can establish compliance on its own. Optim EOS provides time-stamped operational data, history and exports that can support applicable reporting, governance, sustainability and compliance processes. Formal assessment, certification and professional judgement remain with the relevant qualified people and authorities.
Who responds to alerts and maintains connected plant?
Alarm routing, response expectations and escalation are agreed for each deployment. EOS records the device, condition, severity, time and status, and authorised users can acknowledge ownership and follow the alarm until it clears. Continuous system monitoring does not imply a staffed 24-hour response centre. Optim Energy maintains Optim EOS hardware and software in scope; connected customer plant remains with its competent maintainer unless explicitly included.
