A modern building produces large amounts of operational data.
CX2 collects data from the building's technical systems, stores it locally, and describes what it means.
The same data can then be used for analyses, dashboards, reports, AI and other tools.
From the building's systems to the finished analysis.
Data comes from many technical systems, is collected on an edge server in the building and described so that people and software alike can understand it. Only then does it become usable for analyses, reports and other tools.
The next eight steps look more closely at each link in the chain.

One building. Many systems. One shared data foundation.
Ventilation, heating and cooling are often gathered in the BMS, the building management system, while lighting control, solar shading, energy meters, solar panels, elevators and other technical systems may live in systems of their own.
CX2 is a shared data layer where data from different technical systems is brought together and used across them.

The building owner should own and control their own data.
CX2 is built around an edge server located at the building.
Operational data is stored here in a local time-series database, so the building owner has access to their own historical data without depending on an external cloud service.

Access to data is not enough.
VE01-TT-401 is clear to the person who knows the system's structure and naming. Outside the original system, that knowledge is often missing.
That is why CX2 links the data points to their physical and functional context in the building. It draws on technical diagrams, floor plans, 3D and IFC models, point lists, specifications and the structure of the building management system itself.

The semantic model is the building's table of contents.
A room is on a floor. A sensor measures the temperature in the room. An air handling unit supplies the room. A valve belongs to a specific heating system.
The semantic model lets analyses and software work with the meaning of the data rather than just the original point names.

Time series tell you what happened. The model tells you what it means.
Used together, the same analysis can be applied to many rooms, zones and systems without first manually translating every single BMS tag.
That makes it possible to automate analyses that otherwise require extensive manual work.

From spot checks to a systematic check of the whole building.
When the system knows which points belong to which rooms, zones and systems, the same check can be run automatically across the building.
That makes it possible to go from spot checks to systematic verification of all relevant zones.

Data is not tied to one particular tool.
Once data is collected, historised and described, it does not have to be tied to one particular user interface.

Data ownership is a core principle of CX2.
Data ownership is a core principle of CX2. The building owner keeps operational data locally and stays in control of how it is used. CX2 is meant to reduce dependency on vendors, not create a new one.
That is why the architecture is transparent: where the data lives, which connections leave the building, who has access, how backup works, how analysis and AI tools get access, and how data is kept separate from critical building automation.
