We measure how intelligent a building is today and accompany it step by step into connected, automated operation. In four phases, explained on one building.

PORTFOLIO OVER TIME2026
One building is the beginning. The portfolio is the goal.
The same indicators, the same prioritisation for every building. Measures are bundled into packages and rolled out across the whole portfolio in waves, all buildings connected through one data model.

How it works
Today, buildings are often a black box.
Heating, ventilation and lighting work behind this door, often regardless of whether anyone is there. How well a building uses its technology has not been measurable until now.
We record every system.
One day on site or automatically from existing data. The assessment checks the level of automation for every system: operated by hand, partly automated or connected and demand-controlled.
Three indicators show where a building stands.
The Smart Readiness Indicator from the EU directive EPBD rates the intelligence of the technology from 0 to 100 %. Added to this are the building automation class according to DIN V 18599 part 11 and the automation class according to DIN EN ISO 52120, each from A to D. All from one assessment.
Many measures, many sources. What comes first?
Every measure has a cost, a saving, a return and a CO₂ effect. But it competes with others, some reinforce each other, some rule each other out. BAIOSS brings all sources together and orders them by the goals you weight. If the goals shift, the order shifts.
Set a target. Accompany. Re-prioritise.
A target value is set for one indicator by a set year. We accompany the way there, compare regularly with the target path and reorder the measures when the building goes off course. Every point below the path is a measure that has been implemented.
Today: data chaos. Nothing talks to each other.
The technical systems on the roof and in the basement have their own controllers, the sun protection is operated by hand, the lighting by switches, the charging point reports to the manufacturer’s cloud. Analyses across the whole building are not possible this way.
Sort, connect, network. The building at the centre.
BAIOSS assigns every system to its equipment and its room and connects everything into a semantic data structure with the building at the centre. Orchestrated, manufacturer-independent, readable by people and machines, directly usable by every planner and every trade.
Now data flows. Agents work with it.
Data streams from every system into the model, agents evaluate it and control back: energy, maintenance, comfort. This only becomes possible through the shared data model of BAIOSS. Every agent can be switched on and off individually, including those from third parties. Your own processes are rethought and set up as agents yourself.
Now it’s your turn.
All systems with a plus sign are clickable, in the building or in the list on the right. Every click moves up one level: manual, partly, automated. The display above the building shows whether the target is reached.
Four phases, one data model.
With BAIOSS from today’s state to automated operation, on one shared data basis, from a single building to the whole portfolio.
1
Understand
Assess the current state
All systems recorded, one indicator per building, in one day on site or automatically from existing data.
2
Decide
Prioritise and plan
Measures from all sources ordered, including those without technology. Target set, checked regularly and re-prioritised.
3
Design
The basis for all trades
Islands become one shared data model used by planners, installers and operators, independent of any manufacturer.
4
Operate
Agents at work
Energy, maintenance, comfort, your own processes. Full control over data and access.
Digitalisation is not an end in itself. It cuts costs, fulfils obligations, makes buildings more pleasant and portfolios manageable. The same data, four perspectives.
OWNERS AND INVESTORS
Less energy, more value.
A connected, automated building uses significantly less heating energy and electricity. The investment pays off within a few years, and the building remains lettable and financeable.

OPERATORS AND FACILITY MANAGEMENT
Better immediately, without investment.
Simply setting up existing technology better raises the smart readiness. Agents detect faults early, maintenance becomes plannable, quotes become comparable.

PUBLIC SECTOR AND SOCIETY
Less electricity, less CO₂, obligation fulfilled.
The building automation obligation under § 56 GModG becomes part of the list of measures instead of a surprise. Every building in the portfolio gets a path towards climate neutrality.
