Issues caught early
Fault detection, control logic analysis, analytics and Foresight work together, so developing problems show before they become breakdowns, complaints or wasted energy.
Apex Innovation Labs
Your building runs on control logic.We help you understand it.
Lower running costs and fewer faults start inside your building's controls. We read the control strategy, check each finding against the live BMS, and work with you to put it right.
Book a conversationScroll
Behind the glass sits the plant.
Air handling, heating, pumps.
Every item of plant follows the controls.
Fans, valves and pumps, all to one strategy.
That is where we start.
Inside the strategy itself.
Inside the controller, ApexAnalytica reads the strategy live.
Ask Apex rates it and shows the evidence behind each finding.
Then it recommends improvements, referenced to ASHRAE Guideline 36 and CIBSE Guide H.

Why Apex
Find issues before they become problems.
Most wasted energy, repeat faults and comfort complaints trace back to how the plant is controlled. We look at the controls, the plant and the meters together, so problems show early and repairs are quicker.

Faster repairs
Ask Apex explains each finding with the evidence behind it. When a visit is needed, the engineer arrives already knowing what to fix.

Optimised plant sequences
Control strategies are rated against ASHRAE Guideline 36 and CIBSE guidance, with improvements such as supply air temperature reset and optimum start. What the existing controls can do now comes first, so hardware is bought only when it is needed.

Spikes spotted as they happen
Anomaly detection flags unusual energy use as the data arrives, not weeks later when the bill lands.

Savings you can evidence
Savings measured against a weather-normalised baseline following IPMVP, the international method for verifying energy savings, with carbon from stored grid intensity.

Supplier electricity invoices checked line by line against your own metered data.
How we do it.
- 01
Read
We connect to the building's controls and read the strategy, the meters and the plant data together.
- 02
Rate
Each item of plant is rated 0 to 5 against recognised standards, with the evidence shown.
- 03
Improve with what you have
Software changes the existing controls can make now, at no hardware cost.
- 04
Plan what to add
Sensors or equipment that would take the rating higher, listed and prioritised.
- 05
Deploy and verify
Changes applied on an engineer's approval, then checked against the live BMS.
Coming soon
Demand flexibility.
Demand flexibility rewards sites for reducing or shifting their electricity use for a short period when the grid is under strain. Because ApexAnalytica already reads every point in the control strategy, choosing which plant responds to an event, and by how much, becomes a configuration step rather than a new engineering project.
ApexAnalytica
One platform.The whole building.
Meters, plant and control logic are read together.
One set of data, not separate systems.
Energy, cost and carbon sit beside the plant.
So you can see what drives them.
One platform for how your buildings run.
Control logic and fault detection come first. Energy, reporting and verification sit alongside them, on one platform and one set of data.
Operations
Command Centre
Findings and alerts from every building, in one place.
Fault detection
Faults identified from how the plant is operating.
Control logic and Ask Apex
The strategy read live from the Niagara station or Trend controllers, explained in plain English.
Energy
Energy analytics
Half-hourly electricity, gas and water, with carbon from stored grid intensity.
Performance tracking
Cumulative deviation from expected use, so drift shows early.
Reports
Built to order, on demand or on a schedule.
Savings and revenue
Measurement and verification
Savings against a weather-normalised baseline, following IPMVP.
Energy generation
On-site generation read from the building's own meters.
Demand flexibility
Demand Flexibility Service events and their history. Automatic plant response is coming soon.
Invoice validation
Supplier electricity invoices re-checked line by line against metered data.
Building IQ
The building's record
The asset data for each building, held in one place.
01
Checked at the source
Findings are verified against the live BMS, not only stored data.
02
Evidence on every finding
The readings, links and logic behind it are shown alongside it.
03
Written for everyone who runs the building
Plain English for owners and FM teams, standard controls terms and point names for the engineers who act on it.
Master systems integration
Many systems.One building.
A building runs many systems.
BMS, lighting, access, CCTV, fire and lifts, often from different vendors.
We join them in one integration layer.
So they can be monitored and operated together.
Master systems integration
Bringing your building systems together.
One team is accountable for how your systems work together, so no problem falls between vendors. A modern commercial building runs many systems from many vendors, each with its own protocol and its own naming. As master systems integrator we bring them together, so the building can be monitored, analysed and operated as one.
- Single point of accountability
- One team responsible for the interfaces between systems, not only the systems themselves.
- Open protocols
- Integration over BACnet, OPC UA, REST APIs, SNMP and MQTT, including Google's UDMI message format.
- One data model
- Every point from every vendor described the same way using Google's Digital Buildings Ontology.
- BMS and metering connectivity
- Building automation over BACnet, Modbus and Niagara, and utility and sub-meter data alongside the plant it serves.
BMS installations
From an empty panelto a building under control.
Each panel is engineered to the control strategy.
Controllers, I/O and wiring.
Then it is programmed and commissioned.
And tested against the design intent.
BMS installations
Engineered, built and commissioned to the strategy.
Controls that do what the design intended from the day of handover. We deliver BMS projects from design through to handover, as building controls engineers.
- Design and engineering
- System architecture, control strategies and technical specifications.
- Control strategy development
- Control sequences written for energy efficiency and occupant comfort.
- Programming and graphics
- Custom programming and clear operator graphics, including Tridium Niagara and Trend Controls.
- Commissioning and validation
- Testing each sequence against its intent, so the system does what the design says it should.
BMS servicing
Service and maintenance for the systems you already run.
Servicing that keeps the controls running as they should, not only the panels clean. We service and maintain building management systems across the major controls platforms.
- Panels
- Control panels inspected and cleaned.
- Software
- Control software reviewed and optimised.
- Backups
- Backups taken of the control software.
- Inputs and outputs
- Every input and output checked, so the BMS reads what the plant is doing.
- Checked in ApexAnalytica
- The results checked in ApexAnalytica after the visit.
- Savings
- Savings shown where they can be measured.

Smart buildings consultancy
A clear specification.A building delivered to it.
We help you plan, specify and set the standards.
Drawing on experience of delivering the work.
Then we oversee delivery.
So what is specified is what gets built.

Vendors bid against one clear specification, so what you pay for is what gets built. Independent advice from engineers who have led BMS teams and delivered projects.
- BMS strategy and planning
- What to keep, what to upgrade and in which order, based on what is installed on site.
- Energy consultancy
- Understanding where energy goes and which changes will make a measurable difference.
