Building Automation

Integrate building technology independently of any vendor

Building technology grows over decades and usually consists of isolated solutions from different vendors. retavi connects ventilation, heating, lighting and access control through open interfaces, controlled from one shared software base - and has gaps and faulty software corrected automatically.

Your benefit

Cross-system control on an open software base

Integrate existing automation stations, devices and APIs

Provide data for monitoring, reporting and operational optimisation

Your starting point

Building check

Tell us about your problems, systems and interfaces. We show what a shared control system looks like, how an outdated controller can be replaced or extended, or how isolated systems can be integrated - with a concept and effort estimate.

Challenges

Isolated trade solutions

Ventilation, heating, lighting and access control run on separate, vendor-specific systems.

No overarching control

A shared view or control across all technical areas is usually missing.

Building data is hard to use

Operating data sits in closed systems and can barely be used for monitoring or reporting.

Existing stations tie up effort

Existing automation stations can only be integrated with extra effort instead of simply being kept.

How retavi solves it

Three steps from isolated systems to shared control.

1

Connect systems

You connect ventilation, heating, lighting and access control through open interfaces.

2

Integrate what exists

retavi integrates existing automation stations instead of replacing them.

3

Control centrally

All technical and structural areas run from one shared software base for monitoring and reporting.

Examples

Control ventilation, heating and lighting for a school building together

Situation

In a modernised school building, an existing building automation system controls heating circuits and ventilation, the lighting comes from a different manufacturer, and shading and room occupancy supply their own signals. Each system works on its own; the combination of occupancy, CO₂ level, window contact, light and temperature has so far had to be checked across several user interfaces.

With retavi

retavi connects the existing trades to a shared industrial PC via suitable communication modules. A C# module implements the room logic: a presence detector activates lighting and demand-based ventilation, an open window lowers the heating setpoint, and elevated CO₂ levels raise the ventilation stage. BACnet serves as the manufacturer-independent communication standard between the trades.

Benefit

The technical implementation follows how the building is actually used instead of rigid point solutions. Operators get a shared, traceable control basis without every trade keeping its own isolated logic. Functionally separate systems stay maintainable and work together in overall operation.
