High reusability, no data duplication
We bundle our reusable Core Foundation Services to create highly efficient IoT services. The uniformity in the architecture provides access to the same data pool of a building via various IoT services. This makes it easier to exchange data between various IoT services, for example, and simplifies administrative tasks such as setting up and managing authorizations as well as preparing and implementing security audits.

NEXOSPACE Service Suite architecture with the Building, Core Foundation Services, and IoT services layers. The Building layer include sensors, building systems, and system models. The Core Foundation Services layer consists of twelve basic services in total. The overlying IoT services, which are divided into the Assist, Operate, Protect, and Sustain clusters, use these services.

The microservice-based architecture is the success factor for providing new and innovative digital building management quickly and efficiently. One example is the basic mechanisms and environments for models from the artificial intelligence arena, which are bundled as Core Foundation Service Building Analytics. Our IoT services combine this service with other basic services to enrich data semantically and provide context for the analysis with AI models.

Creating Building Digital Twins

Building Digital Twins structures the information from buildings with semantic knowledge graphs and creates a digital copy of a building. The Core Foundation Service uses open ontologies developed by Bosch to consolidate data from facilities from different manufacturers and models into a standardized logical structure. This facilitates seamless integration and interoperability of the various systems within your real estate. Thanks to the standardized data structure, you can analyze information in combined views, aggregate data according to individual requirements and, for instance, accurately compare the energy consumption of multiple buildings.

Building Analytics – Forecasting building data

The Core Foundation Service Building Analytics offers advanced functions for the model-based forecasting and integration of voice-based artificial intelligence. To forecast values, the service uses smart algorithms based on specialized models developed in-house for building management with the incorporation of leading AI libraries. These are packaged in Domain Expert Insight Models (DEIMs) and provided in the respective IoT service. When it comes to generating language, current large language models (LLMs) from established cloud providers are incorporated to implement innovative applications. This allows you, for instance, to predict the energy consumption of your buildings intelligently or to query it based on a dialog with a chatbot.
