(canceled)

A non-transitory, computer-readable storage containing instructions that when executed by a computer cause the computer to operate a building (100) comprising systems (112.1, 112.3, 122.1, 122.2, 122.3, 136.1, 136.2, 136.3) which are installed in the building and act as a data source, each system being assigned one of a plurality of domains (110, 120, 130) of the building, by:

• providing a digital twin (160), by means of which at least one part of the building (100) is imaged as a model, wherein the plurality of domains (110, 120, 130) are combined in the digital twin (160),
• obtaining data (154) detected by the systems, supplying the data to the digital twin (60), and processing the data via the digital twin, and
• operating the building (100) by using the data (156, 158) processed by the digital twin (160).
