01 / The operating picture

Every building runs on dozens of systems. Almost none of them speak to each other.

How a building automation system is built

A modern building is a collection of good systems that behave badly together: HVAC, lighting, access, CCTV, parking, fire, guest rooms, energy meters. Each has its own interface, its own alarms and its own version of the truth.

IBMS is the layer that turns that collection into one operating picture. Not another dashboard on top, but the integration architecture underneath: one data model, one alarm model, one set of interlocks, one audit trail.

We build that layer on the product line that fits the project — KNX or BACnet where the plant is multi-vendor, Modbus or DALI where the field devices demand it, Loxone where local-first control and a single device ecosystem help. Every one of them has to expose open interfaces.

02 / What breaks without it

The cost of fragmentation is operational, not theoretical.

Four failure modes we design out of every project.

The building is already complex

01

Information islands

Every subsystem has a separate workstation. Operators reconcile alarms by phone and memory.

02

Manual routines

Schedules, reports and energy checks depend on someone remembering to run them.

03

Blind energy

Meters report consumption, not causes. Savings projects start without a baseline.

04

Specialist dependency

Simple changes require the original integrator, the original laptop and the original password.

03 / The architecture

Three layers. One source of truth.

The platform is flat by design: fewer gateways, fewer translations, fewer points of failure.

Operator experience & business decisions

Dashboards, mobile access, reports, tenant and guest views, portfolio rollups. Every role sees the building at the resolution it needs.

Supervision

One data model, one alarm model

The integration core normalises every subsystem into a common object model, then applies schedules, interlocks, alarm routing and audit logging.

Device

Open protocols & local control

Loxone controllers and gateways connect the plant room, the floor and the guest room. Control stays local; the platform supervises.

Product ecosystem

One platform, from the controller to the room.

The IBMS is built on Loxone hardware and software. These are the product families we specify, configure and commission.

04 / Capabilities

What the platform actually does.

Six capabilities that show up in every successful IBMS deployment.

Office lobby with green accent lighting

Integrated monitoring & control

Live graphics, trends and commands for every integrated subsystem, from one interface.

Loxone Touch controls on a dark surface

Cross-system interlock

Access opens a room; lighting, HVAC and CCTV respond. Rules are configured, not hard-wired.

Energy & carbon intelligence

Meter data, degree-day normalisation and baselines that make savings measurable.

Bedroom with integrated lighting

Healthy building performance

CO₂, PM2.5, TVOC, humidity and temperature held to explicit design targets.

Restaurant interior with warm lighting

Guest room & hospitality

Room status, PMS integration, scenes and energy control for hotels and resorts.

Campus building and lawn

Multi-site operations

One operating model across buildings, with local control and central oversight.

Design position

The operator is the user.

Most IBMS tools are built for the integrator's demo, not for the person on shift at 02:00. We design for the operator: clear hierarchy, explicit alarm states, one-click drill-down, and no hidden modes.

  • Role-based views for operators, engineers and management
  • Alarm routing with escalation and acknowledgement
  • Every command and setpoint written to an audit trail

Inside the building

The same operating model, at different scales.

Workplaces, guest rooms, residences and campuses — one architecture, tuned to the space.

05 / Integration

14 subsystems. One integration model.

We integrate what the building already has, then add the control layer that makes it behave as one system.

Fire alarm linkage

Fire alarm linkage is implemented through potential-free contacts and supervised inputs, with the fire system remaining the authority.

06 / Healthy building standard

Comfort is a specification, not a feeling.

We design to measurable targets for air, water and thermal comfort — then trend them for the life of the building.

ParameterAcceptableHigh performance
CO₂< 1,000 ppm< 600 ppm
PM2.5< 35 µg/m³< 15 µg/m³
TVOC< 0.5 mg/m³< 0.4 mg/m³
Formaldehyde (HCHO)< 0.4 mg/m³< 0.3 mg/m³

Design targets from the Aster Building Automation healthy-building standard. Final values are agreed per project and local code.

Questions, answered

The things owners and consultants ask first.

All questions
What is a building automation system?
A building automation system monitors and controls HVAC, lighting, shading, energy, access and other building services from one architecture. It replaces isolated controllers and workstations with a common data model, schedules, alarms and cross-system logic.
What is the difference between BAS and BMS?
BAS usually refers to the control layer that runs plant and field devices. BMS is the management layer that supervises those systems, handles alarms and produces reports. In smaller buildings the terms overlap; in larger portfolios they are distinct scopes.
What is the difference between BMS and IBMS?
A BMS manages building services. An IBMS integrates multiple subsystems and often multiple buildings into one operating picture, with cross-system interlocks, a unified alarm model and portfolio reporting.
How is building automation priced?
Price follows point count, system scope, controller and gateway count, integration complexity, commissioning and documentation. We quote after a point schedule and scope review rather than a per-square-metre guess.
Can you integrate KNX, BACnet and Modbus?
Yes. We integrate KNX, BACnet IP, Modbus RTU/TCP, DALI, Loxone Tree/Air/1-Wire and other open interfaces through gateways and a documented point map.
Can the system keep running without the cloud?
Yes. Control and interlocks run locally on the controllers. Remote access and dashboards are optional layers; a WAN outage does not stop local schedules, alarms or HVAC control.
