RealEstateCore

for and by property owners

What are the benefits for the property owners?

Property owners can use RealEstateCore to describe the data of interaction within the buildings that they operate – as well as the management, storage, and sharing of this data. RealEstateCore is a modular ontology, that is, a collection of data schemas that describe concepts and relations that can occur in data that is generated to model buildings and building systems, or that is sourced from such systems.

Having the shared language that these data schemas provide enables property owners to connect their buildings with new services on a large scale, and not have to worry about building- or technology-specific implementation details and formats

Ever increasing amounts of data are generated by and within buildings

Several different systems exist to control climate, lighting, access control, IoT devices, etc., not to mention the need to interact with facility management and financial systems. These large amounts of heterogeneous data need to be organized into digital twins if they are to contribute to cost-efficient and environmentally friendly real estate management.

RealEstateCore adds language for control

RealEstateCore adds language for control over technical systems, facility maintenance, certification, financial aspects, etc. Valuable data flows more freely, formerly complicated system integrations become easier and more reliable, and building managers gain a consistent overview of building operations. This means that smart building benefits become far more accessible – both now and in the future, as the possibilities continue to grow.

An extendable ontology that describes anything in its context of a building

Several industries have interfaces to the construction industry and buildings in particular without this being their main industry. As there is often a need to describe some sensor, product, device in the context of the building in which it sits and as the building is itself also a feature of interest in the context of a smart city, there is a demand for a minimal, extendable ontology that describes anything in its context of a building.

Not replacing, but rather merging different standards

RealEstateCore is not aiming to replace all standards, but rather intends to bridge existing standards and find the common denominators. RealEstateCore uses and maps existing standards in a pragmatic manner. RealEstateCore focuses on merging and bridging four domains:

  • Business administration
  • Digital representation of the building’s elements – BIM
  • Control and operation of the building BMS
  • IoT technologies
